The first step is to install the platform in the distribution network of the
City of Évora - Unesco World Heritage Monument
1. Évora municipality:
• 54.000 inhabitants
• 1.307 km2 of area
• Urban and rural areas
2. The project includes:
•
•
•
•
•
30k Energy Boxes
341 DTC in MV/LV transformers
Integration of IT systems
Communications infrastructures
Set-up of new services and products
3. Involvement of the major players
of the municipality
4. Coordination with the national
electric vehicle charging network
23
EDP is also installing a technology that will offer new services and
products to a selected group of consumers

The consumer will benefit from the development of new and better
energy services
Today
Tomorrow
• Based on quarterly manual
meter readings combined
with energy estimation
• Based on remote reading and real
time consumption
Acess to the
information
• Avaliable by internet only
and based on the last meter
reading
• Increased flexibility through an
access to the energy profile using
internet, displays, PDA, etc.
Services
• Contract changes typically
need to be scheduled and
performed on location
• All contract changes can be
performed remotely
Tariffs
• Fewer price plans and tariffs
• Increased flexibility in pricing and
tariffs.
• Limited value added services
• Capacity to inform consumers by
different channels including
social networks
• Energy management kits

Conclusion
•
On top of improving the quality of service while maximizing operational efficiency, DSOs
also need to integrate more renewables and to promote energy efficiency
•
Smart grids are the answer to these new challenges; smart metering is one first step
towards that direction
•
Involvement of customers and other stakeholders is key for the success of the project,
as well as a solid communications infrastructure
•
EDP Distribuição developed an innovative SmartGrid Project, tested in Évora during 2010
and 2011. It will allow to test smartgrids from a commercial perspective (cost-benefit
analysis).
•
The project is aligned with the most innovative trends in the sector across the world.
•
Évora InovCity is a privileged location for testing the new solution being developed and
to prepare a future nationwide rollout
