Storage, as identified by the Smart Grid Forum, is one of the key smart interventions likely to be required in the future smart grid. However, challenges in leveraging the full potential of storage on distribution networks to benefit other industry segments, and a lack of scale demonstrations are currently hampering the efficient and economic uptake of storage by the electricity sector. The Smarter Network Storage (SNS) project is carrying out a range of technical and commercial innovation to tackle these challenges and facilitate more efficient and economic adoption of storage. It is differentiated from other LCNF storage projects through the demonstration of storage applications across multiple parts of the electricity system, including the distribution network but also outside the boundaries of the distribution network. By demonstrating this multi-purpose application of 6MW/10MWh of energy storage at Leighton Buzzard primary substation, the project is exploring the capabilities and value in alternative revenue streams for storage, whilst deferring traditional network reinforcement. The project aims to provide the industry with a greater understanding and a detailed assessment of the business case with the full economics of energy storage, helping to accommodate increasing levels of intermittent and inflexible low carbon generation. The project was awarded funding of £13.2 million by Ofgem, under the Low Carbon Network Fund (LCNF) scheme in December 2012 and will last four years, from January 2013 to December 2016. 1.2 Summary of Progress In this reporting period the project has completed the construction and commissioning of the Smarter Network Storage facility, making it Europe’s largest battery owned by a network company. Despite some issues encountered during the commissioning process, the facility is now operational and is completing testing ready for the System Integration Testing phase, however there remain outstanding system defects that need further investigation which are covered in more detail later in Section 2.1. Figure 1: The site in May 2014 (left) and later in November 2014 with landscaping and fencing (right) During this period Work Stream 1 (WS 1) has seen a vast effort in completing the civil and electrical construction work at Leighton Buzzard and continuing into the testing phase. All installation work has been completed and the Electrical Storage Device (ESD) has passed site acceptance testing, with 6MW of power exchange now demonstrated and at time of writing is ready for System Integration Testing to begin. During this period Work Stream 2 (WS 2) moved from software design phase and entered into development and testing phase. The software suppliers completed development and their testing; in turn the project team integrated the software solution and carried out acceptance testing using UK Power Networks’ infrastructure. Integration testing is in progress to make the solution ready for trails. Workstream 3 (WS 3) has identified a range of individual trials to demonstrate the storage capabilities and various value streams. A comprehensive suite of detailed trial design documents has been completed which describe the UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 3 of 54 Smarter Network Storage Progress Report December 2014 hypotheses, technical requirements, processes, risks and expected outcomes. This includes pre-trial tests which chronologically sit between commissioning of the energy storage system and handover of the software and hardware infrastructure before the kick-off of the trial phase once the storage is operational. The pre-trial tests aim to serve as confidence building tests as well as system integration tests for the various software and hardware sub-systems. The initial trials to be carried out will be network-related, which have been designed by Imperial College London, and support the work assessing the contribution to security-of-supply of shared-use storage. The pre-trial designs and the initial network-related trial designs have been drafted and are awaiting confirmation of the exact execution dates and the PI naming tags before completion, which are both expected in early January 2015 after completion of the full commissioning of the SNS hardware and software infrastructure. The key focus and deliverables from Workstream 4 (WS 4) during the period has been the completion of a report detailing Commercial Arrangements for Integrated Use of Flexibility (SDRC 9.3 report, SNS4.6) together with the completion and signing of agreements with Smartest Energy and Kiwi Power. This together with a confidential report compiling other relevant evidence, mainly meetings and workshop notes, forms the evidence demonstrating the successful completion of successful delivery reward criteria 9.3. 1.3 Risks and Issues Summary Procurement Risks and Issues RTU firmware had to be upgraded to cope with DNP3 protocol – This was because GE documentation was inaccurate, as a result additional consultancy was required from GE to resolve this at an extra spend of £3,100. Vodafone & BT data communications issues – Vodafone made a number of errors during the delivery of the VRF connection at Leighton Buzzard, which is now completed. This resulted in delays in connectivity tests and unplanned resource utilisation. Installation and Other Risks and Issues 11kV switchgear joggle-box error – There was an error made by a sub-contractor of the supplier of the 11kV 1 switchgear that required the replacement of a joggle box required to extend the existing 11kV switch-board. This was completed behind schedule but the supplier agreed to cover all additional costs. Samsung SDI rack BMS error – Samsung SDI advised that the BMS circuit board they had supplied had a fault that caused intermittent operation; this was identified on another installation. Replacement circuit boards were supplied to resolve this issue by Samsung SDI and installed by S&C Electric and their subcontractor causing some short delays. Communications Interference issues – Electromagnetic interference causing loss of communications on a CAN-BUS interface between the batteries and the battery management system caused significant delays, meaning the completion of the commissioning was behind schedule. This has been rectified by improving software resilience, replacing the cables with better screened cables and the installation of physical containment. There are some further issues relating to circulating currents within the building that are still under investigation at the time of writing, but are expected to be resolved within the next reporting period. Towards the end of this reporting period and moving into the start of the next period full end to end integration testing of the system will be carried out. Naturally work during the design stages has attempted to mitigate all problems that could be encountered in enabling the different sub-systems to work together; however as with all innovative work involving first-of-a-kind software and hardware platforms, there is an elevated risk of unexpected issues arising that could cause further delays to the programme. 1 Joggle box: switchgear extension panel to enable on switchgear make/model to be connected to another UK Power Networks (Operations) Limited.

The key learning outcomes are summarised below, with further information available in Section 7.1: Building a large scale ESD in a building presents different challenges to a containerised solution The application of some standard charges as part of The Electricity Supplier Obligations could lead to disadvantages for storage operators, and double counting of industry charges; The application of some distribution-related charges do not always reflect the potential value or capability that the storage system can offer; The firmware of Remote terminal Units (RTUs) should be up to date prior to testing; Improved understanding of storage amongst energy suppliers and standardisation of energy supply contracts is needed to facilitate the adoption of energy storage DNOs may need to contract or develop additional expertise in DC design To ensure that the project is continually capturing learning resulting from the project, regular workshops involving the project team are scheduled, outside of other governance and project meetings, which provides a forum for specifically discussing and capturing new learning. In addition, the partner forums, which have been held on 28 July and 18 November, provided an opportunity to discuss and capture any additional learning with external project partners. As part of WS 5, which is dedicated to learning capture, dissemination and stakeholder engagement, the Knowledge Dissemination Roadmap has been reviewed and updated to reflect the evolving plans for engagement and dissemination by the centralised learning and dissemination team. The following internal dissemination activities, project–related events, communications and engagement have been carried out during this period. Further detail is available in Section 7.2: Network control briefings to ensure key staff remain engaged and integrated into processes for operating the storage; Construction site meetings and tours at the working level and management level; Contributions to an EPRI Software Case Study Report; Contributions to Storage and BSC Report by Elexon; ESOF Meeting – A presentation was given on the business case for the SNS installation in Shetland, hosted by SSE; Knowledge sharing with the Japanese Institute for International Socio-Economic Studies; Energy Central Article on Smarter Network Storage; The project was featured in a short film, commissioned by the ENA on several aspects of Smarter Networks, including the use of storage.

The following organisation chart, in Figure 3, shows all the allocated resources within the SNS project structure as of December 2014. Figure 3: Smarter Network Storage organisation chart Engagement continues with the core project partners both through ongoing work, and at a more senior level through the Partner Forums. A Partner Forum meeting was held on 28 July, where an update was provided on construction and installation progress and the activity around SDRC 9.3 was discussed. UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 7 of 54 Smarter Network Storage Progress Report December 2014 A second Partner Forum was also held on 18 November at the storage facility in Leighton Buzzard. This provided our project partners an early opportunity to have a tour of the storage facility, and discuss further the trial work to be carried out in the next phase of the project. 2.1.1.2 Project Governance The governance model, as described in the previous six month progress report, is unchanged and continues to be operated by the Programme Management Office. The model identifies two distinct streams: Solution Governance and Project Governance and helps to ensure a focus on developing effective technical and commercial solutions to meet learning outcomes, as well as an effective structure for ensuring the overall solution is delivered on time, to budget and to the appropriate quality. Further information on this governance model, including supporting project control and reporting mechanisms, is documented in the SNS Project Handbook (SNS5.4). A number of additional processes have been developed to cover specific activities relating to operating the ESD during the trial phase. These are listed below, but include processes for developing and agreeing trials, reconciling and billing from the delivery of commercial services and internal reporting. Key issues encountered No significant issues have been encountered in this area during the reporting period. Key deliverables SNS 3.16 – Trials Process SNS 3.17 – SNS Trials and Operation Invoice Billing Reconciliation Process flow 2.1.2 Project Planning As highlighted in the previous 6-month progress report, the current reporting period has represented a critical period in the project with a significant amount of activity occurring as the construction and commissioning took place, in parallel with the development and testing of the IT solutions. More regular progress reviews and workstream-level project planning has therefore continued throughout this current reporting period to ensure progress is closely monitored and plans updated accordingly. Several issues encountered during the commissioning of the storage facility have led to a delay of approximately eight weeks in trial start, which are further described in Section 2.1.3 This has required ongoing re-phasing of various dependent activities, but will not affect the level of learning generated from trials or subsequent key milestones due to the flexibility and design of trial arrangements in the following phase. An updated high-level summary of the SNS activities and deliverables achieved in 2014 is provided below in Figure 4. UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 8 of 54 Smarter Network Storage Progress Report December 2014 Figure 4: SNS 2014 key deliverables summary Similar to the previous year, a strategic planning session was held with the project team on the 7 November 2014. This provided an opportunity to review the objectives and structure of the project team ahead of the transition to the operational and trial phase, identify the priorities and core work packages for 2015 and any additional dependencies and risks for the year. Key issues encountered No significant issues have been encountered in this area during the reporting period. Key deliverables No new deliverables have been developed in this area during the reporting period. 2.1.3 WS 1 – Energy Storage Hardware WS 1 covers the design and development of the storage system; hence many of the activities in the current stage of the project are encapsulated within this WS. The focus within this reporting period has been the installation, commissioning and testing of the energy storage system (see Figure 5) within the new building at Leighton Buzzard, along with the additional equipment and network modifications required for its safe and effective integration. Detailed preparations have been made for the operation of the system including the preparation of user guides and training materials; delivered to UK Power Networks staff in the local area as well as to network control engineers and other relevant staff.

Specifically this has included the approval of the appearance of a low fence along the edge of the land being leased to the council for the use of the local residents. This includes the provision of ongoing access for the council and the Environment Agency to maintain the land they are leasing and the Clipstone Brook respectively. At the close of this reporting period the site will have been de-mobilised and the landscaping completed. The landscaping is in progress at time of writing; having been delayed slightly by the warm autumn. The semi-mature trees needed to be dormant before they could safely be moved. Documents have been prepared to ensure that upon the completion of the site works the requirements of the Section 106 agreement with Central Bedfordshire Council are met. This includes the lease to the land that is being made available for the use of the local residents, as shown in Figure 12; transfer to the council of the land they requested alongside the Clipstone Brook, as shown in Figure 6; and a payment to the council to support the maintenance of the land being leased to them.

During this period there were some late design changes that were implemented in the project. Although all relevant stakeholders had been consulted during the design phase some late requests were made to add an additional 11kV circuit breaker to the primary substation bus-bar and an additional Ring Main Unit. These are being used to support the 11kV network in the area by enabling additional 11kV circuits to be run from the primary substation and to provide additional network flexibility. Although the work for this has been carried out by the SNS project the funding for all the work has been provided separately 2.1.3.2 Construction On 15 May 2014, in the last reporting period, the interior of the new building was handed over to S&C Electric to install the batteries, power conversion systems, fire suppression system and cooling equipment. The first battery deliveries from Samsung SDI arrived on 19 May. These were the first of 14 shipping containers of equipment from the Korean supplier. Due to the difference in levels between the ground, a container on a lorry trailer and the building loading bay an intermediate level scaffold platform was constructed, as shown in Figure 7. This allowed the palletised equipment to be easily offloaded from the containers onto a scissor lift that could raise them to the level of the building loading bay, reducing the time taken to offload each container and ensuring employee safety in the process. Figure 7: Completed scaffold loading platform and high level DC bus-bars being assembled. The first elements to be installed were the DC bus-bars, hung from the high level structure of the building above the position of each of the battery arrays (see Figure 7). The battery rack frames were then positioned and bolted together and to the floor to create a stable structure. Once these frames were in place they could be populated with the battery UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 11 of 54 Smarter Network Storage Progress Report December 2014 trays themselves. This process carried on until early July, with the last array then completed on 18 August following the delivery of the Power Conversion Systems (PCSs). Following the completion of the battery arrays the different cable supports, cabling and ancillary equipment were installed, as shown in Figure 8. The control cabling on the battery racks was installed between 22 July and 29 August with the power cabling to connect the battery trays together left to the last stage before testing. This was done to minimise the risk posed by the energy stored within the batteries by keeping them isolated in as small units as possible. The PCSs arrived in sections (see Figure 8) on 31 July from the USA and re-assembly was completed on 6 August. These were then positioned with the transformers in the SNS building. Work then commenced on re-assembling them from the shipping splits and connecting up the main and auxiliary cables. Figure 8: PCS assembly on site and DC cable supports and termination boxes. During this time further work was done inside the SNS building to install the fire suppression system and the heating, ventilation and cooling system. These involved the mounting of acoustic louvers, fans, ducting, vents, gas sampling pipework, fire grade cabling, control cabling and control boards, some of which are shown in Figure 9.

Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 12 of 54 Smarter Network Storage Progress Report December 2014 Figure 9: Fire suppression bottles and a ventilation louver during installation. Outside the building, work commenced in earnest during June to stitch the energy storage device into the local 11kV network. From 11 June the CDM construction site was extended to include the existing Primary Substation adjacent to the SNS building. A scaffold loading bay was erected to allow equipment to be safely delivered to the building as it is also raised above the site flood level. Using this platform on 16 June new 11kV circuit breakers were delivered to extend the existing switchboard and enable the connection of the energy storage device (see Figure 10). Between 17 June and 1 July the new auxiliary battery systems, automatic voltage control panel and Remote Terminal Unit (RTU) were delivered. As it is not possible to run multiples of these systems, significant effort was required to integrate these with the existing equipment so that the new unit could cope with the requirements of the energy storage system.

Due to the increased auxiliary demand and the requirement for this supply to be secure the existing padmount substation (providing low-voltage supplies) was removed and replaced with two new distribution substations on raised plinths. Construction of the bases and access platform began in mid-July and was complete on 27 August. The first new 11kV cables were installed on 21 August with the last cables on 9 September and all joint bays reinstated during the first two weeks of October. The changes to this area of the site are shown in Figure 11. Figure 11: Before and after of the area within Leighton Buzzard 33/11kV site with the local substation providing the site auxiliary supplies. UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 14 of 54 Smarter Network Storage Progress Report December 2014 Once the majority of this work was complete UK Power Networks’ security contractor mobilised to site to install the permanent security. The new building is secured to current company standards but the security at the adjacent existing site was upgraded to protect the network connection of the energy storage device. This minimises the likelihood of anyone interrupting the supply with potential network security or commercial implications and secures the high value assets installed. During the current period there was a break in to the site on 17 September causing damage to the site office. Nothing was taken and no damage was done to the SNS building itself or equipment contained within it. During the week commencing 6 October the site management and facilities were moved into new cabins to enable the original cabins to be removed and the land to be landscaped prior to leasing the land to the council. The hoarding has also now been removed along with the hard-core that had been laid to form a working surface. Topsoil that had been stockpiled from the original site clearance could then be distributed to make up the ground levels and provide for planting. Figure 12: Levelling and preparation of the ground to be leased to the council for the use of the local residents. At time of writing the planting is complete and, by the close of this reporting period, the site will be completely demobilised. It is planned to leave a single cabin on site to provide a safe room for meetings and to facilitate visitors to site to support the dissemination of the learning from this project to other DNOs and the wider energy storage industry. 2.1.3.1 Testing The initial 11kV energisation of the SNS switchboard took place on 12 September with sequential tasks following to test the step-up transformers and AC side of the Power Conversion Systems. This formed part of a detailed testing programme governed by the SNS1.3 Testing Strategy document. The electrical testing continued largely without incident including full reactive power tests until the testing of PCS DC side and transfer of power to/from the batteries. This is described in more detail in “Key Issues Encountered” below. The ESD was broken down into its constituent units and commissioned by PCS and by Battery Energy Storage Device Manager (BESDM – section of the ESD). The PCSs were checked following re-assembly then their auxiliary power and control systems were tested. The PCS inverters were then tested to their full reactive power capability before control by the BESDM devices was attempted and real power testing. For each BESDM (representing two battery arrays) the communications were tested first, then basic control of the DC contactors then initial charge and discharge tests. Following the resolution of the key issues (described below) the batteries were then put through a “State of Health” calibration to confirm the batteries could be charged/discharged fully and an endurance test, where any poor cell performance would be detected. Once each of the six BESDM devices and their respective battery arrays were tested in this way the communications were enabled between these and the Battery Energy Storage System Manager (BESSM) controller. Tests on the whole ESD could then be carried out. The ESD system tests, operating in each mode required driven by the battery management system BESSM, are complete. This marks the completion of the Site Acceptance Tests of the equipment supplied by S&C Electric and their sub-contractors Younicos and Samsung SDI. System Integration Tests including other aspects of the IT and forecasting system covered in WS 2 can then be carried out at the end of this reporting period through into the start of the next one.

Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 15 of 54 Smarter Network Storage Progress Report December 2014 Aside from the main electrical systems the ancillary systems were also all thoroughly tested. In order to sign off the fire suppression system it was required to test the ability of the building to maintain air pressure to a certain level. This ensures that if released the suppressant gas remains in place for long enough to suppress a fire. The building passed this test at the first attempt. The heating ventilation and cooling systems were tested to ensure the appropriate responses to temperature change are made. The auxiliary supplies, metering and communications systems were also thoroughly tested. 2.1.3.2 Health and safety considerations During this reporting period there have been two areas of focus regarding health and safety considerations. Firstly has been the planning and management of the on-site construction work. Secondly has been the preparation to bring the energy storage device into operation and preparing the business to receive it. During this time there have been over 21,000 man-hours worked on site from S&C Electric and their subcontractors alone with regularly 50-60 people on site at any time. For an extended period the site has been operating 12 hours days Monday through Thursday to enable the efficient use of staff who have travelled to the area for the work and are staying locally. This has required the full time attendance of one or at times two site mangers from the Principal Contractor Morrison Utility Services (along with site management and supervisory staff from S&C Electric and their subcontractors) to ensure that the work is co-ordinated and staff are controlled. At time of writing there have been no Lost Time Incidents on the construction of this project. The follow are some positive comments received by Morrison Utility Services from visitors to the sites through their feedback cards: “Well organised site. Very good induction, clear, balanced and effective. Site controlled, partitioned and zoned for access control and work activity. Impressive generally, taken guidance for our systems”; “Site person in charge gave me thorough site induction. All my questions were answered. I found the induction was very descriptive and was presented excellent”; and “Clear instruction, good visual aid for induction. Presentation Highlighted to risks on site, very good”. On 9 July the site was audited by the Considerate Constructors Scheme receiving a very good score in the final report. The specific feedback points were discussed with Morrison Utility Services to identify where further improvement might be achieved. Figure 13: Considerate Constructors Scheme banner displayed prominently on the construction hoarding. During the build phase specific labour and manual handling saving devices were developed including the scaffold platform discussed above and a device for the safe and efficient installation of the battery trays into the racks on site. In preparation for the operation and ownership of the ESD by UK Power Networks significant effort was put into developing approved procedures for the new equipment. This included discussions with the internal Health & Safety teams and engineers as well as the suppliers involved. Discussions were also had with other DNOs to incorporate their UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728.

Acknowledgements specifically go to Ian Lloyd from Northern Powergrid for supplying and discussing their procedures, in addition to engagement from the Energy Storage Operators Forum. Version 1 of an Engineering Operating Standard (EOS), “EOS 09-0074 Energy Storage Device at Leighton Buzzard” was approved on 22 October. This first version contained all available information at the time of commissioning, which was required before the system could be brought into operation. A revised version is planned for re-approval in the next reporting period with the inclusion of final details incorporating as-built photographs and screen shots from control systems that were not ready for inclusion in issue 1. This document becomes the reference document for site visitors, ESD operators and network control engineers who have to interact with the ESD and points towards the various subsystem user guides where applicable. At time of writing some initial training material has been developed to use to train both the local area engineering staff and the network control engineers, those who might interface with the ESD on a day by day basis. This consists of presentation slides and spoken training describing the system and operating requirements along with the issue of a copy of the EOS document. Plans are in place to develop interactive training including guidance videos on the specific tasks involved which it is expected will be produced in the next reporting period. At time of writing as the construction work is coming to a close our CDM Co-ordinator is working closely with all the parties involved in the project to ensure that a detailed and accurate Health and Safety file is compiled for the work on site. It is expected this will be largely complete by the end of this reporting period with the final details closed out in the next period. Key Issues Encountered There were several issues encountered during this reporting period, as might be expected. These are detailed below in turn. Upon initial preparations to position the battery racks in the new building late May/early June 2014 it became apparent that the cast floor slab was not sufficiently flat for all the racks in an array to site level. This was resolved by using steel packing shims to sit underneath the rack frames to ensure they could be correctly installed and would be supported at all points required. Detailed investigations revealed that although a few sections of the floor were outside design tolerance, even floor sections within the design tolerance were not sufficiently level. Tighter cast concrete floor tolerances or the installation of fixing rails would be required for future applications. This would need to be considered in future designs with regards to flexibility and future upgrades within a fixed building. To make the 11kV connections to the existing primary switchboard work was required to extend the existing Reyrolle LMT board with new HSS Eclipse circuit breakers coupled together with a bus-bar joggle chamber. This was a critical task that had been done multiple times before so was not considered a high risk to the project. It transpired that a subcontractor to HSS had made an error in their design and provided an incorrect joggle chamber, stepping the new switchgear too far backward. This meant that the back of the gear was not correctly supported and the operating handle fouled the side of the joggle chamber, preventing correct operation. Once HSS were made aware of this issue they took steps to construct a new joggle chamber in a reduced time-frame and covered all UK Power Networks costs incurred in the replacement. This delayed the 11kV re-configuration work and particularly the modification of the SNS2 feeder CB but these delays were managed within the tolerance available in the site work programme. There were two delivery issues relating to the novel equipment supplied to the project. The batteries supplied by Samsung SDI were shipped with two separate palletised stacks of batteries on top of each other within the shipping containers. Due to the motion in transit and the fact that the pallets were not tightly held in place the top layer moved during shipping. It was the not possible to off-load them directly on site due to the equipment available; requiring double-handling of equipment and some off-site storage. The second issue was a delay in shipping. Due to some problems at their Wisconsin facility S&C Electric were not able to carry out the final testing and ship the PCS units until seven weeks after the original planned ship date. The installation of these was not on the critical path of the project but eliminated any opportunity to complete the installation work on site early and carry out extra testing. It also required one of the battery arrays to be left out to allow for the delivery of the PCS units to their final position. We were advised on 28 July 2014 Samsung SDI had identified (on another installation) a problem with their rack BMS circuit boards. They had designed, manufactured and tested replacement circuit boards that were shipped to the UK for UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 17 of 54 Smarter Network Storage Progress Report December 2014 installation. This caused a small delay in the work on site that was within the project contingency; none of the associated costs were borne by UK Power Networks. By far the biggest issue encountered within WS1 during this reporting period came during the initial real power testing of the batteries. Due to the time and logistic constraints it had not been possible to bring the batteries and PCSs together for testing until the site installation (one is manufactured in Korea, the other in the USA) and we were aware this presented an additional risk to the testing phase. During the initial “real power” tests, significant problems were identified with the communications over a CAN-BUS link between the Younicos Battery Energy System Device Manager (BESDM) PLC and the Samsung SDI battery rack BMSs. These were the first tests to use the “DC chopper” side of the PCSs and to charge/discharge the batteries. This affected all the battery arrays to varying degrees and resulted in the inability to run any further testing. Following some initial investigations on site that determined this was an Electro Magnetic Compatibility (EMC) issue an expert from TUV SUD, a specialist EMC testing and consultancy practice, was brought in to carry out detailed testing, assessment and to provide recommendations. Obtaining sufficient measurements was a challenging issue due to the ESD only being able to operate for short periods before tripping off due to the comms issue and requiring resetting. In parallel with this testing, investigations into the components involved were carried out. It was confirmed they were all CE marked stating tested compliance with the EMC directive and the factory test reports were assessed. It was determined that the test reports were showing compliance and that the issues were therefore most likely to stem from a result of the scale and specific nature of the installation situation and connecting cabling. Initial recommendations from TUV SUD included adding additional EMC shielding and containment as well as changing the cabling used for the CAN-BUS to screened cables (it transpired that the original cables supplied by Samsung SDI were not screened). Implementing these changes, along with some software updates to improve error rejection and resilience, allowed testing of the ESD to resume. At time of writing more detailed investigations are still underway, however the full 6MW of the ESD has been successfully operated over a period of several hours and the overall impact to UK Power Networks has been approximately a six week delay. Once testing resumed following the rectification of the EMC issue some other unexpected performance issues have been identified. Part of this has been traced to some errors in the installation leading to circulating currents, which may also be exacerbated by the unique nature of the installation in a raised, purpose-built building but as stated above further investigations are underway and it is expected to have this resolved early in the next period. Figure 14: Testing of the CAN-BUS signals There have been additional issues encountered around the level of audible noise in the PCS/Transformer room while the ESD and the cooling system is in operation. This restricts the ability of people to be in this room during operation without hearing protection. It was noticed during the autumn weather that there were a few places where the structure of the building housing the battery was letting in water. This was however sufficiently clear of all electrical equipment to not present a safety UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 18 of 54 Smarter Network Storage Progress Report December 2014 hazard. It was identified that where the ends of the Kingspan cladding were hidden behind a piece of trim these were not all completely sealed, allowing the wind to blow water in through the join. The whole building was checked and the issue was quickly resolved by Morrison Utility Services. 2.1.4 WS 2 – Smart Optimisation & Control Systems (SOCS) WS 2 is responsible for managing the design, development, testing, integration and deployment of the end to end IT solution; Smart Optimisation and Control System (SOCS). This platform will manage the shared-use of the storage across multiple applications, whilst ensuring network security is maintained. The SOCS solution comprises two distinct sub-systems, the software hosted within UK Power Networks’ corporate IT environment, called the Forecasting, Optimisation and Scheduling System (FOSS), delivered by AMT-SYBEX, and the control software co-located with the storage at site, called the Energy Storage System (ESS), delivered by Younicos on behalf of S&C Electric. Progress against plan During this period WS 2 entered into the software development and IT infrastructure implementation phase. Software The SOCS solution is made up of: Forecasting, Optimisation and Scheduling System (FOSS) – built on AMT-Sybex’s various Affinity Suite modules Energy Storage System (ESS) developed by Younicos and S&C Electric on a Zenon SCADA platform. ESS consists of the following functional composition: o Battery Energy Storage System Management (BESSM) o Battery Energy Storage Device Management (BESDM) o Storage Management System (SMS) ENMAC – UK Power Networks’ Network Management System Remote Terminal Unit RTU PI – UK Power Networks’ data warehouse Enterprise Service Bus (ESB) – UK Power Networks’ IBM Message Broker ESB (WebsphereMQ) As per the agreed design and approach defined in SDRC 9.2 (Confirmation of the Smart Optimisation and Control System design) the suppliers produced the technical specifications for each module; developed the code and tested the software prior to delivering into UK Power Networks environments.

Successful exit from FAT enabled the supplier to deploy the solution onto UK Power Networks infrastructure in a controlled manner. Each deliverable was then Site Acceptance Tested (SAT) by replaying the FAT scenarios on ‘Production to be’ environment, these tests were conducted by UK Power Networks and/or the supplier based on the nature of the test. At time of writing the SAT of the SOCS installation is complete and the project team are ready to commence System Integration Testing (SIT), Non Functional Testing (NFT), User Acceptance Testing (UAT) and Operational Acceptance Testing (OAT). These all use test plans/cases developed by UK Power Networks and Newcastle University. Through all the testing phases, defects were identified, captured and tracked using UK Power Networks defect management tool (IBM Rational Rose). The priority and severity of each defect was agreed by all parties through defect management forums and subsequently released using the above testing model (shown in Figure 15). Often a number of test cycles iterations are required before a successful conclusion of each test. UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728.

Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 23 of 54 Smarter Network Storage Progress Report December 2014 IT Infrastructure As part of Work Stream 2 scope, the IT infrastructure was procured, installed, validated against architecture design and made available for deployment of the SOCS solution. In particular, in this reporting period the following environments were implemented: FOSS Test environment – comprising of an application server and a database server; on these servers Oracle and IBM WebSphere were installed and then connected the application server to a test instance of the IBM Websphere MQ/IBM Integration Bus. AMT-Sybex then installed the FOSS application and database tier connecting to a test instance of PI database. Finally, after the all the connectivity checks, the FOSS system was ready for Site Acceptance Test (SAT) on this environment. FOSS Production Environment – similar to FOSS Test environment, the production environment comprising of an application server and database server; fully installed with Oracle and IBM WebSphere and integrated with the production instance of the IBM Integration Bus. Then AMT-Sybex installed the SAT accepted version of FOSS solution onto this Production environment and connected the database with Production PI SCADA database. Finally, after the all the connectivity checks, the FOSS system was ready for System Integration test on this environment. BESSM test – this system was set up in Berlin by Younicos which was connected to test BESDM machines which in turn was connected with a battery simulator. UK Power Networks conducted its Factory Acceptance Test on this environment. Following the FAT period, this environment was used for testing connectivity with IBM Integration Bus and the Test RTU. BESSM Production – as part of the commissioning plan the BESSM and BESDM production infrastructure was installed and implemented at Leighton Buzzard. This production environment is being used to perform the end to end System Integration Testing. ENMAC Pre-Production – an extract of the current ENMAC system was taken from production and restored in a Pre-Production instance of ENMAC, and then the SNS changes were configured on top. This had to be aligned with the line drawings defined by the drawing office team to change the EPN diagram to reflect SNS on the control system. ENMAC Pre-Production was linked to the PI testing database. RTU Test environment – a test RTU was modelled on the final Production RTU design and configured accordingly. This was connected up to the Pre-Production ENMAC system, a network simulator and BESSM test system in Berlin. The test RTU was used to confirm the DNP3 measurements settings between BESSM and the RTU RTU Production – as part of the SNS project it was a strategic decision to replace the RTU with a new T5500 RTU, this was installed at Leighton Buzzard during this phase. The SNS configurations were then installed on top of the existing setup allowing SNS data to be transmitted to control and PI system via production ENMAC. The SOCS technical solution is split between multiple sites with the principal UK Power Networks sites being the Leighton Buzzard sub-station, UK Power Networks control centre and the UK Power Networks data centre. There are external connections from non-UK Power Networks systems being integrated into the design. The ESS is sited at Leighton Buzzard and has the need for resilient, real-time communication with the storage device. Therefore, the following communication requirements were delivered in this reporting period: Communication with storage device at Leighton Buzzard via a fibre broadband connection and backup ADSL link; Communication with the on-site RTU at Leighton Buzzard; Communication with other SOCS components via the UK Power Networks’ ESB; Provision of remote access for partners/suppliers to provide support. UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 24 of 54 Smarter Network Storage Progress Report December 2014 The communication architecture enables ESS to communicate with different parts of the UK Power Networks’ network infrastructure: The on-site RTU is on the SCADA VRF (Virtual Routing and Forwarding), whilst the ESB is on the corporate VRF, and third party support is normally provisioned through VPN tunnels through the corporate VRF. As a result a number of firewall rules had to be configured across the UK Power Networks’ communication infrastructure. Key Issues Encountered A number of issues were encountered during development and test phase of the project. The key ones that had an impact on the project time lines are listed below: RTU firmware had to be upgraded to cope with DNP3 protocol When testing data points between BESSM and RTU it transpired that the firmware version used on RTUs did not have the DNP3 protocol capabilities contrary to technical documentation. Thus after numerous test and consultations with General Electric (GE) it was deduced that a latest version of the RTU firmware was required. This delayed the RTU configuration and testing by approximately four weeks which in turn had an impact on testing the DNP3 settings defined in BESSM. Additional consultancy was required from GE at an extra spend of £3,100. Vodafone & BT data communications issues There were number of process related issues with getting Vodafone to deliver the VRF connection at Leighton Buzzard. After a number of site surveys it was deduced that BT Openreach needed to dig the road outside the UK Power Networks building in Leighton Buzzard. Secondly, the routers and switches installed were incorrectly configured. This did not have any impact onto the overall project timelines, though it resulted in the WS lead spending a lot of time chasing the supplier. Revisited the Energy Cost model for the optimisation algorithms During the design walk through of the optimisation module, it was agreed with Newcastle University that the energy calculation can be improved and thus a revised model was designed. This has now been implemented as part of the optimisation solution. This delayed the delivery of the FOSS phase 2 by approximately eight weeks form originally planned. There were no addition costs incurred as AMT-Sybex and Newcastle University absorbed this additional effort in their timetable to accommodate this refinement. Key Deliverables During this period the following milestones were achieved: SNS 1.3 – SNS Testing Strategy SNS 2.5 – Demand Forecast Error Analysis SNS 2.10 – SOCS Training SNS 2.12 – Long Term Electricity Demand Forecast for Energy Storage Scheduling SNS 2.13 – Improving Long term Electricity Demand Forecasting Through Data and Interactions FOSS and ESS testing and results SOCS Test and Live Environments UK Power Networks (Operations) Limited.

Progress against plan In this reporting period, the detailed trial designs have been completed and the DNO trials are ready to be initiated as illustrated in Figure 16. 2013 - Services Approach - Services Use Cases - Conflicts, Synergies and Commercial Strategies for Storage 2014 2015 - Wholesale Market Trials - Detailed Trial - TSO Trials Designs - DNO Trials (In Progress) - Optimised /Integrated Trials - Trial Data Analysis - Storage contribution to Security of Supply 2016 - SDRC 9.6 Analysis of Integrated Storage Contribution to Security of Supply - SDRC 9.7: Successful Demonstrations of Storage Value Streams - Value, Carbon Benefit and Cost Targets of Storage and SDRC 9.6 and 9.7 Reports Figure 16: High Level Deliverables of WS 3 during the Project Lifecycle Within DNO trials, a number of pre-trial tests will be conducted to validate that the SNS software and hardware solution is able and ready to deliver the core and long-term trials. It should be noted that numerous tests have been conducted previously under WS 1 and WS 2 commissioning and testing processes; however these WS 3 pre-trial tests are part of the whole SNS System Integration Testing, firstly because they require a number of SOCS subsystems and ESS hardware to be integrated and secondly, because they aim to verify that the anticipated functions of the end to end SNS solution comply with the requirements to deliver the core trials. Specifically, the pre-trial tests to be conducted are: Set-point stability and accuracy tests: the aim of these tests is to ensure that the required set-points were sufficiently realised by the BESSM control system and that network voltage changes does not affect the realisation of the set-points. Reserve tests: the aim of these tests is (i) to ensure that the interface with KiWi Power was efficient in transferring dispatch/deactivation signals for the delivery of reserve services (i.e. Fast Reserve and Short Term Operating Reserve) following an instruction from National Grid and (ii) to ensure that BESSM delivers the service within required performance criteria that include defined energy delivery within specific timelines. Response tests: the aim of these tests is to ensure that BESSM is able to deliver response services (i.e. Frequency Control by Demand Management, Static and Dynamic Firm Frequency Response) adhering to the required technical characteristics (i.e. dispatch power vs grid frequency characteristic) within the required response time (i.e. 2 seconds). Peak shaving tests: the aim of these tests is to ensure that BESSM is able to deliver peak shaving using active and reactive power capabilities of the ESS taking into account various pre-defined parameters (such as loading limit at the 11kV) and trigger signals from the RTU to flag N-1 conditions. The above tests are planned to be carried out and their results will be documented in the DNO Trials report which will be completed in the next reporting period. Operational and reporting templates for the trial period have been developed. These templates will be used by the SNS operational team to inform the control room and network operations of the upcoming trials on a weekly basis, but also aggregate operational and anticipated costing information to assist with reconciliation of the cash flows between UK Power Networks and the trial partners during the trial period. UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 26 of 54 Smarter Network Storage Progress Report December 2014 Modelling work has been conducted to support the negotiations between UK Power Networks and National Grid for deciding the pricing for frequency response services provision. Availability and utilisation prices were decided based on the installed cost of SNS, fixed and variable charges that are anticipated during its operation and an index-linked component for energy utilisation and these have now been factored into the new business case view as shown in Section 3. The metering system that will be used in SNS has been designed and developed with Siemens plc and FAT was witnessed successfully on 26 June. The metering system was installed, and was commissioned on 15 November. The contracts required for metering system provision and metering system operation have been finalised and signed. A spreadsheet-based tool that will serve as a decision making tool for acceptance or rejection of a tolling profile has been developed. Every Friday, a tolling profile for the following week will be sent by Smartest Energy and the SNS operational team will use this tool to evaluate whether the proposed profile is technically feasible. This tool requires as inputs the load forecast for the evaluation week and the active schedule for that week that indicates the services that have already been booked and their parameters. A triad avoidance process has been developed. During each triad period (i.e. November to February inclusive each year), Smartest Energy and KiWi Power will send approximately 25-40 triad warning messages via email to the SNS operational team highlighting the possibility of a triad on the day of the warning. Triad forecasting has been out of the scope of the SOCS system and the SNS operational team will consult the triad avoidance process on receipt of a triad warning message to decide whether amendment in the daily dispatch schedule is required to minimise the potential costs from importing energy during the triad period. Key issues encountered No issues have been encountered in this area during this reporting period. Key deliverables SNS 3.5 – Service Trial Detailed Approach SNS 3.16 – Trials Process Flow SNS 3.17 – Trials Invoicing and Reconciliation Process 2.1.6 WS 4 – Commercial & Regulatory Frameworks This work-stream is responsible for the commercial and regulatory aspects of the project, including assessment and validation of specific business models for storage, and identification of key regulatory barriers. 2.1.6.1 Smart Commercial Agreements The key focus and deliverables from this work-stream during the period has been the completion of a report detailing Commercial Arrangements for Integrated Use of Flexibility (SDRC 9.3 report, SNS4.6) together with the completion and signing of agreements with Smartest Energy and Kiwi Power. This together with a confidential report compiling other relevant evidence, mainly meetings and workshop notes, forms the evidence demonstrating the successful completion of successful delivery reward criteria 9.3. During this reporting period, the new Storage ‘Aggregator Services Agreement’, which has been under development over the course of this year, was completed. The contract allows delivery of the range of ancillary services to be trialled with Kiwi Power. Kiwi Power has also put in place back-to-back commercial arrangements with National Grid for the provision of ancillary services using the storage capacity. If storage is to be operated in this multi-purpose way, the need to access the balancing markets also leads to the requirement for access to the wholesale electricity market to enable charging and discharging when required.

Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 27 of 54 Smarter Network Storage Progress Report December 2014 In the SNS model operated by the project, charging and discharging of the battery is enabled through Smartest Energy, an energy supplier with whom an Energy Supply and Tolling agreement has also been successfully completed during the period. This agreement also provides an opportunity for an additional ‘Tolling’ service, which enables the supplier to take commercial control of the device for a period of time to manage their imbalance risk or arbitrage, in return for a fixed fee. Negotiation of these first-of-a-kind contracts has generated a comprehensive understanding of the structure, costs and benefits of all non-energy related charges and levies that helps to further inform the business case for storage, in addition to key market-related learning around issues that could pose further barriers to the adoption of energy storage. SDRC 9.3 demonstrates that these commercial arrangements for the independent service trials and optimised period of operation have been developed and translated into ‘skeleton’ contract heads of terms, providing the basis of commercial arrangements that could be tailored for other forms of flexibility and leveraged system wide by other DNOs. 2 The SDRC 9.3 report has been published on the SNS project web page and was submitted to Ofgem before the end of October. This learning report describes the implemented smart commercial arrangements for the SNS commercial operating model, which represent first of a kind contracts for operating storage in this way, and shares them in the form of ‘skeleton’ contract heads of terms. It also identifies new specific learning relating to additional barriers in implementing such agreements for storage, and in the frameworks for certain industry charges. The project has been consulted by Ofgem on the legal and regulatory barriers work undertaken, the details of which were reported in the June 2014 progress report. A presentation was made to the Ofgem WS6 Smart Grid Forum group. In addition, a response was provided to a letter dated 14 November 2014 from Ofgem seeking a more detailed view on how storage fits into the current European framework, in particular the ‘third energy package’ (Directive 2009/72/EC). Key issues encountered With regards to the Aggregator Services Agreement, Kiwi Power required suitable back to back arrangements to support all of the balancing services being provided. Suitable arrangements were in place for all services with the exception of Firm Frequency Response (FFR). Here, it was necessary for Kiwi Power to negotiate a bespoke back-toback agreement with National Grid. Whilst this negotiation took much longer than was anticipated, it did provide the project with an opportunity to understand the assessment methodology operated by National Grid, and an opportunity for National Grid to understand more about the technical capabilities of energy storage. It also identified that there was a trade-off between the level of pricing and the length of contract that could be achieved. This results from National Grid factoring their greater uncertainty of requirement into the prices they offer resulting in a short term increase, and is an additional challenge that new storage developers may face when securing finance for storage projects.

Work associated with developing this business case will come from the specific learning that is gained throughout the life of the SNS project. This generic business case will be dependent upon the form of business model which is chosen and the assumptions that are made regarding all of the current unknowns. This project is looking to identify and quantify many of these unknowns and apply them to the various different business model structures to help drive forward the adoption of storage for the benefit of customers and industry. These business model structures were consulted upon in 2013 3 (SNS4.1 – Storage Business Model Structures Consultation) . For the particular project installation, we are tracking changes to the main drivers of the business case and it is the project’s intention to use this section to provide an ongoing update to the general economics of the installation as these drivers evolve and as further learning emerges. During this period, further refinements to the final costs of the civil build and electrical connection aspects have now fed into the business case assessment. In addition, the conclusion of the pricing discussions with National Grid have allowed more accurate pricing to be included for the ancillary services that are to be trialled in the upcoming phases of the project. The revised discounted cash flow incorporating all of these changes is shown below.

Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 30 of 54 Smarter Network Storage Progress Report December 2014 ‘First of a kind costs’ represent non-core storage installation costs, including other R&D work, and first-of-akind development costs within SNS; ‘Technology cost reduction’ represents the expected price reduction in core storage technology occurring between the period of the SNS installation, and the point in time when storage would otherwise be installed as part of a BaU intervention to relieve the network constraint; and System cost savings represents the wider system efficiencies materialising from reduced curtailment, reduced greenhouse gas emissions and system balancing and operation savings. In this reporting period, the overall lifetime installed cost (£11.4m) has become very slightly more favourable, reflecting more accurate actual costs from the final stages of the site work. The estimate for future revenues, over the 10 year period, has also increased favourably to £2.6m due to the inclusion of finalised pricing for FFR. The overall revenues represent a conservative even split between the two key ancillary services STOR and FFR. Additional services are being trialled as part of the SNS project, but have not been included here in the interests of maintaining a conservative estimate. As an example, benefits from triad avoidance have not been factored in, due to the uncertainty in estimating the actual triad periods, however could represent a reasonably significant additional benefit for commercial storage operators. As in the previous 6-month report, a basic sensitivity analysis has been performed to indicate an approximate upper bound of expected revenues for a commercial operator assuming the storage is just optimised towards providing the higher value service of FFR. The table below shows these results: Scenario Future Income Estimate (10 yr NPV) Future Net Method Cost (10 yr NPV) Even mix of STOR and FFR (as above) £2.6m £3.3m FFR Only £4.7m £1.2m Table 3: Storage revenue sensitivity to operating different services As shown in the table above, if just the higher value service of FFR is provided, revenues of circa £4.7m may be possible which would reduce the future net method cost to £1.2m, making the storage solution cost competitive with the conventional reinforcement (even without the system cost saving aspects included). This highlights the importance of optimisation in maximising the benefits for storage, and is due to be explored further within the project using the SOCS platform currently under development.

Page 37 of 54 Date 30 December 2016 Smarter Network Storage Progress Report December 2014 7 Learning outcomes 7.1 Main Learning Outcomes from the Reporting Period During this reporting period, SNS has continued to capture specialised learning relating to the construction, installation and commissioning as well as the regulatory and market aspects of distribution-scale energy storage. The key learning outcomes from this reporting period are explained below. A number of key findings have been identified through the installation and commissioning of the storage facility, development of the SOCS platforms and development of the smart commercial arrangements. These include: 1. Building a large scale ESD in a building presents different challenges to a containerised solution Important learning has been generated by the project as a result of carrying out the storage installation and commissioning at this scale in a purpose-built building. Overall system design becomes more important and additional aspects need greater consideration when installing an ESD into a building rather than in containers. The reduced distance and screening between plant and equipment presents additional challenges around electromagnetic interference that may not otherwise be apparent. Although the root causes of the issues identified are not fully confirmed at time of writing, considerations from suppliers for a “whole system” design and testing of the systems they supply rather than individual elements may have gone some way to eliminating the problems seen and the manufacturer has also learnt valuable lessons from this stage of the project. 2. The application of some standard charges as part of The Electricity Supplier Obligations could lead to disadvantages for storage operators, and double counting of industry charges In developing the smart commercial arrangements for the SNS operating model, that have been shared in SDRC 9.4 (Commercial Arrangements for the integrated use of flexibility), a number of key learning points have been generated in relation to a number of standard industry charges and their applicability for storage. Climate Change Levy In particular, the application of the Climate Change Levy (CCL) to storage, which is an energy tax administered by HM Revenues & Customs (HMRC) under primary legislation introduced through the Finance Act 2000 leads to some discrepancies. It is typically levied on energy consumed by industrial and commercial users (but not domestic consumers). The statutory instrument (SI) that defines the CCL framework defines ‘renewable sources’ of energy as being ‘sources of energy other than fossil fuel or nuclear fuel and includes waste provided that it is not waste with an energy content 90 per cent or more of which is derived from fossil fuel’. Aside from the debate that storage could be considered to be time-shifting energy only, and not a source as such, this definition could give latitude for storage qualifying as a renewable source of energy, as it is not fossil fuel or nuclear. The SI however states that ‘the amount of a supply of renewable source electricity is to be calculated at the point at which such electricity is first delivered from a generating station to a distribution or transmission system within the United Kingdom (excluding territorial waters)’. This confirms that a LEC is allocated at the original point of generation. As export from storage relies first on prior import of energy, this existing generation output may be from a renewable source, and so a LEC could already have been issued. If this was the case, issuing a LEC at the point of export from storage would therefore be double-counting. By default, it may be argued that CCL charges should apply to storage operators, which has the effect of increasing the import charges for everyday operation. However, from engagement with the HMRC, it was recognised that the guidance did not deal explicitly with the treatment of energy storage and it was advised that storage in a battery would not change the fact that it was initially generated from a renewable source. Therefore HMRC would not see the discharge of electricity from a (lithium-ion) battery storage device as generation, and therefore it would not be subject to CCL upon discharge. It was possible to reflect this exemption in the commercial arrangements surrounding the SNS facility, but it is believed the industry would UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 38 of 54 Smarter Network Storage Progress Report December 2014 benefit from formal guidance or amendments to the scheme to ensure consistent application of this exemption and avoid disadvantages for storage operators. Contracts for Difference & Feed in Tariff Similar to the above learning point, the application of renewables subsidy payments including FIT and Renewable Obligations to storage operators increases import charges and leads to further disadvantages over conventional generation response providers. Feed-in tariffs with Contracts for Difference (FIT CfD) will replace the current support mechanism, the Renewables Obligation (RO), in 2017 after running in parallel from 2013 and will be administered by Ofgem. The first payments to developers start from April 2015 and a levy will be applied to all suppliers in proportion to their supply account to pay for it. Imported energy used to charge up storage devices will by default be subject to this levy. Similar to the CCL charges above, the subsequent export of energy from storage means that this same energy will be ‘consumed’ for a second time, meaning that a subsequent customer will be liable for FiT payments on the same energy. This suggests that suitable exemptions for storage need to be implemented to prevent double-counting and prevent any disincentives for storage developers. 3. The application of some distribution-related charges do not always reflect the potential value or capability that the storage system can offer The project has identified that there may be scope to improve pricing frameworks to better reflect the benefit that storage could provide to the distribution networks in some circumstances. A particular example relates to charges to connected customers for reactive power. Reactive power exchange with the network is currently charged based on the type of asset, i.e. load or generator. The charges are calculated based on the amount of reactive energy exchanged with the network, but only the amount above 33% of the active power exchange at each half-hourly period, is charged. Storage systems which include power electronic inverters have the ability to provide four-quadrant operation (i.e. independent provision of real and reactive power in different directions). However, with the current pricing structure there is no mechanism to be appropriately compensated (or charged) for combinations of real/reactive power that are in different directions (e.g. import real power, export reactive power). As a consequence, there is currently no incentive for any third-party owned/operated storage connected to the network to provide any reactive power services, that could potentially be utilised for distribution network support, for example to reduce losses or improve power quality. 4. The firmware of Remote terminal Units (RTUs) should be up to-date prior to testing The RTU unit is a key device in the overall system that facilities communication between the onsite control system BESSM, the SCADA network and the FOSS control system. An issue was encountered, as described further in Section 2.1.4, during the testing of the RTU which manifested as an inability for the BESSM system to communicate correctly with the RTU. The cause was the firmware version used on the RTUs which did not have the correct DNP3 protocol capabilities as described in the latest available technical documentation from GE. Several days of diagnosis and testing were needed to identify this issue, which could have been avoided if the latest firmware had been installed at the beginning of the test process. 5. Improved understanding of storage amongst energy suppliers and standardisation of energy supply contracts is needed to facilitate the adoption of energy storage A reasonably significant amount of time and effort was required to develop the contract with Smartest Energy for the energy supply to the storage facility. This was in part due to the first-of-a-kind nature of this contract UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Page 39 of 54 Smarter Network Storage Progress Report December 2014 between a large-scale DNO-owned storage facility and an energy supplier, but also due to some of the ambiguities over application of supplemental industry charges, as described in learning points 1 and 2 above. Contracts more typical of the core business of energy suppliers, for example power purchase agreements with generators, or standard commercial tariff agreements with demand customers, have been in existence for a long period of time, and so require relatively little input and development to implement. In order for this particular commercial model to be a viable and interesting proposition for energy suppliers, much greater standardisation is needed in these contractual arrangements. Increased awareness of the benefits and operating characteristics of storage amongst energy suppliers would also benefit the industry in the same way. The risk otherwise, is that storage developers could find it challenging to put commercial arrangements in place for efficient access to wholesale markets, and potentially fails to secure the ability to charge/discharge at economical rates. 6. DNOs may need to contract or develop additional expertise in DC design It has been identified that DNOs may not have the expertise within their organisation to review and sign-off on contractor’s design of DC systems. DC system design has some differences from AC system design which may lie outside the experience of DNO engineers. If this is the case a third party consultancy may be required or a commercial structure implemented where the contractor self certifies but takes on all the commercial risk. 7.2 Learning, Communications and Dissemination Activities in this Period As described previously, a comprehensive Knowledge Dissemination Roadmap has been developed in order to capture all the key learning activities and events. This has continued to evolve and be updated with the project and is available on request. There are four core elements to the Knowledge and Dissemination Roadmap, covering the following areas: Internal Communications; External Communications; Local Engagement; and Knowledge Dissemination. The following provides an update on the progress on each of the above elements: 7.2.1 Update on Internal Communications Network control briefings – Meetings have been carried out with our control engineers to show them the SNS facility, ahead of training, as well as to allow input into the control screen designs to ensure they remain engaged and integrated into processes for operating the storage; Construction site meetings and tours – Monthly meetings have continued to be held by Morrison Utility Services at the Leighton Buzzard construction site to review progress, discuss any risks and issues and engage with third parties involved in the programme, for example communications providers. Capital Programme management meetings – Monthly meetings have been held with Capital Programme at the senior management level, to review progress and spend, and discuss any risks or issues during the construction and commissioning Training sessions for local engineers – A training session has been held for the engineers in the area local to Leighton Buzzard who might get called out to operate or inspect the ESD, or potentially visit to assist investigation of a fault.

It allows for the communication and escalation of key risks and issues within the project, it also defines where decisions will be made and how this will be communicated back to the WS level where the risk or issue has arisen. Risks are reviewed weekly at WS level and fortnightly at project level by the Project Board. Key project risks are then escalated to the Project Steering Committee for review and approval of the mitigation on a monthly basis. 9.1 Full Submission (BID Risks) – update This section is provided in Appendix C. 9.2 Risks raised in the current reporting period REF NO. Status R0104 RAG WS RISK & IMPACT DESCRIPTION - WS 3 R0105 G WS 3 R0106 - WS 3 Connections works for Stewkley Rd 23MW PV Farm are incorrectly perceived as an overrun or modifications to the consented SNS development by the Council and/or residents. Output from the Stewkley Rd 23MW PV Farm is not monitored, or considered in FOSS. Consideration is not given to the visual impact of the connection equipment for Stewkley Rd PV Farm. R0107 - WS 4 R0108 A WS 2 R0109 - WS 4 No LV metering on auxiliary feeders. R0110 G WS 4 R0111 A WS 2 Under the EST Agreement with Smartest there is a risk that UK Power Networks will have to compensate Smartest for lost triad benefit costs if during a week that Tolling has been chosen and they schedule to export from the device during what is later confirmed as a triad period, and UK Power Networks have chosen to disrupt their submitted schedule casing them to lose valuable triad benefit. ENMAC migration from pre-production to production has a resource conflict. Pricing information/back-to-back FFR arrangements with National Grid are still outstanding when KiWi service is due to start on 31/10/14. ENMAC & RTU development delayed. Testing of ESS cannot take place without RTU. MITIGATING ACTIONS Risk Closed: Risk was raised with Connections directorate, and civil works agreed to be carried out in existing compound under permitted development. Monitor risk and initiate mitigating actions if Stewkley Rd Farm connection is confirmed. Risk closed: Visualisations were updated to check visual impact & discussed with OP&C (UK Power Networks consents team). Feedback from UK Power Networks’ consents team was that no further engagement with the council is needed. Risk closed: Negotiations between KiWi and National Grid completed. 02/10/14: RTU software upgraded to the latest version. ENMAC testing started. New problems have been identified with RTU calibration. Risk closed: metering installed. Don't choose tolling option during a likely triad period (i.e. between November and February). To eliminate the risk completely, the Tolling option should not be selected between November and February.

R0020 R0026 R0027 R0029 R0030 RAG Status RISK & IMPACT DESCRIPTION Detailed load studies to understand maximum demand and future increases. Estimates of availability to be refreshed on a regular basis. Ensure ongoing tracking of demand. The lack of available technical, commercial and project resources result in delays in project delivery. Resourcing plan completed during resources within UK Power Networks/Future Networks. Significant connections activity in the area puts pressure on SNS business case. A connections customer prepared to invest a lot, could pay for the third circuit and transformer ahead of expected date. Or there could be pressure on SNS to release the capacity for connectees. The project has been scoped to look at multiple ownership/operational structures, so should be robust to legislative changes. A G G UPDATE Site load growth exceeds expectations, pushing peak demands beyond the spare capacity range of the battery. A G MITIGATING ACTIONS Unfavourable changes in legislation or market arrangements that restricts on the usage and reduces the identified benefits. Resource availability during the life cycle of the project resulting in delays. Early resourcing/recruitment Provide adequate notice when planning meetings, workshops and events. Resource pooling within Future Networks. UK Power Networks (Operations) Limited. Registered in England and Wales. Registered No. 3870728. Registered Office: Newington House, 237 Southwark Bridge Road, London, SE1 6NP Additional storage provision has been included within the design to allow for capacity to be increased to 18MWh. Future connection requests continue to be monitored. Evaluation of load profile to be reviewed on ongoing basis. Project team mobilised, including appointment of two external contractors to ensure deliverables remain on track. Ongoing resourcing meetings being held to ensure regular reviews and monitoring of resource. Monitor and track connections activity and materialisation of load growth Develop action plan for post-security of supply operation (e.g. as part of ANM). The project has been scoped to look at multiple ownership/operational structures, so should be robust to legislative changes. Trial demonstrations still possible in conjunction with National Grid on a demonstration basis only. Ongoing resourcing meetings being held to ensure regular reviews and monitoring of resource.

R0032 R0035 R0038 R0039 R0041 R0042 RAG Status RISK & IMPACT DESCRIPTION A - - G UPDATE Local opposition to building the storage facility causes both delivery timescales being extended and reputational damage. External stakeholder engagements to be conducted prior and throughout the project to ensure concerns are managed appropriately. Continue to monitor LB Substation mailbox, and respond with input from the Care team. There is significant flooding at the site whilst building works are taking place causing damage and delays. Put temporary protection place to stop significant flooding of the site. During the project delivery stage the appropriate UK Power Networks staff do not engage adequately or in a timely manner with the Project. Resulting in poor engagement and delays. Design and implement a robust internal and external stakeholder road map to identify all the key stakeholders. Step up engagement with control team and Operational teams as we approach commissioning. Strong engagement and collaborative working with partners. Put in place strong commercial agreements. Ensure clear scopes of services and deliverables from partners defined. Full continual engagement with partners, with penalties clauses included for late delivery. Contingency has been built into well designed plans. Tender process was carried out for several projects aspects and provides alternatives therefore reduces this risk. - - MITIGATING ACTIONS Commercial arrangements with Smartest, National Grid and KiwiPower are not acceptable to all parties resulting in delays. Delay in delivery of hardware or software from partners and contractors. Delay in delivery of hardware or software from partners and contractors. Key Project partner(s) withdraw their participation in the SNS project during the project has started, leading to delays. UK Power Networks (Operations) Limited. Registered in England and Wales.

R0043 R0044 R0045 R0046 R0051 R0053 RAG Status RISK & IMPACT DESCRIPTION MITIGATING ACTIONS UPDATE Partner resources not available to complete work, attend meeting etc. Resulting in project delays and issue with quality of work. All partners are to provide multiple names as contacts, with deputies of the same standing. Also partners are to provide an escalation path should any issues be identified. Lack of clear scope/requirements for Partners result in scope creep and delays. During scoping/design phase ensure all elements of work are captured through engagement & 'sign off' from key internal stakeholders. All partners have provided multiple names as contacts, with deputies of the same standing. Also partners have provided an escalation path should any issues be identified. Acquisition of AMT-SYBEX by Capita and change of resource at KiwiPower raised as separate risks. Poyry notified of a resource change in October 2014 but working contact remains engaged. Some Product Descriptions to be completed and approved for partner-led work and reports, however 50% of project work is now complete. Partners do not have a clear delivery plan, which will result in delivery delays and missing milestones. Partners are involved in producing a project plan and monthly reports to track progress. Payment for any works will be linked to its completion on time to cost and quality. Ensure close collaboration between storage supplier and Capital Programme directorate to ensure planning app reflects requirements. Partners are involved in producing a project plan and monthly reports to track progress. Payment for any works will be linked to its completion on time to cost and quality. Some overspend has occurred, within project contingency. Partner spend is higher than anticipated. Overspend on project studies or services. Partners may have concerns about the level of resource they need to dedicate to the project. The risk is that partners withdraw involvement, leading to delays or additional costs to mitigate. Make contingency available for additional partner costs. Provide update to partners in forums on expected upcoming resource needs. Monthly account reconciliations and forecast undertaken to understand financial reporting. Any deviations on forecast or unexpected elements will be reported or escalated as necessary. Remain sensitive to time draw on partners where there is no funding Resource forecasts have been provided to project partners for improved forward visibility.
