BACKGROUND
GIS MAPS & ENERGY ACCESS MODELLING
CONCLUSIONS AND RECOMMENDATIONS
Background
The Energy Commission was set up by an Act of
Parliament, the Energy Commission Act, 1997 (Act 541)
with functions relating to the regulation, management,
development and utilisation of energy resources in
Ghana.
The Energy Commission is the technical regulator of
Ghana’s electricity, natural gas and renewable energy
industries, and the advisor to Government on energy
matters.
GIS-based Energy Access
Project Objectives
General Objective
Contribute to effective implementation of
policies & plans for achieving energy access
targets in Ghana by 2020.
4
Specific Objectives
1.
Review existing energy policies and plans for increasing
energy access in Ghana.
2.
Use GIS to collate & analyze data, provide timely
information on pop. distribution, socio-economic
activities, status of energy access programs.
3.
Identify gaps in energy policies & plans for achieving
expected energy access targets by 2020 and provide
timely mitigation measures.
4.
Develop methods & tools to facilitate business models,
investment plans and capacity development to
complement planned activities to achieve energy access
targets by 2020.

GEAR Toolkit
• GIS-based Energy Access
Review (GEAR) Toolkit for
viewing / investigating
– Communities Electrified/Un-Electrified with attributes
(population, recommended electrification option, costs of
electrification, etc)
– User defined queries (Community/ District/ Region/ Ghana)
– Electrification Rates
• GEAR Toolkit has been updated into Ghana energy
access database. www.ghea.energycom.gov.gh
Network Planner:
Columbia University / Earth Institute Decision
Support Tool for Electricity Planning
Network Planner is:
• A datadriven, algorithmic
method for designing
least-cost national
electricity plans
It includes:
• A graphic interface for
displaying results
• Numerous data-views
to see detailed and
summary cost and
technical data.
Network Planner ‘GIS-based Energy
Access Project’ –
Study initiated to complement efforts at increasing access
to electricity and other modern energy forms by conducting
assessments and developing tools for capacity building
Study used Network Planner (developed by Prof
Modi, Columbia University) to estimate costs of extending
electricity to 2600 communities using grid extension, diesel
mini-grid and off-grid solar home systems
Cost of extending electricity to the communities using least
cost technologies came to about 700 million Ghana Cedis
GIS-based Energy Access Review (GEAR) Toolkit was
developed to present results in graphical format
Ghana
• Greater
concentration of
communities
connected to the
grid in the South
• Unconnected
communities
distributed across
the whole country
Map of mini-grid
communities
showing solar
radiation levels
and small hydro
resources
Solar mini-grids in
Upper and Northern
Regions should be
considered
Many cases of mini-
grid communities
close to potential
small hydro sites in
Upper
West, Northern, Brong
Ahafo, Ashanti and
Western Regions
Map of off-grid
communities
showing solar
radiation levels
and small hydro
resources
Solar radiation
highest in Upper and
Northern
Regions, between 5.2
and 5.6 kWh/m2/day
Many off-grid clusters
in Upper West and
Northern Regions
Upper West Region map showing recommended
technology for un-electrified communities
No. of communities –
294.
Off-grid = 10%
Mini-grid = 9%
Grid = 81%
Comes after Northern
Region with highest
number of communities
recommended for offgrid
Smaller clusters of
identifiable off-grid
communities
Northern region map showing recommended
technology for un-electrified communities
No. of communities –
660.
Off-grid = 20%
Mini-grid = 10%
Grid = 70%
Region with highest
number of communities
recommended for offgrid
More smaller clusters
of identifiable off-grid
communities
Summary of Findings
Network Planner recommends 7% for off-grid and 8%
for mini-grid with remaining 85% for grid
electrification.
Choosing least cost technology reduces cost of
extending electricity by close to US$ 100 million.
There are a good number of off-grid community
clusters which could be given out as concessions for
decentralised solar home systems
Many mini-grid communities are in solar rich parts of
the country and a good number are close to potential
small hydro sites
Conclusions
• Ghana on course to achieve “universal access to
electricity” by 2020
• Ghana is unlikely to achieve 50% access to LPG by
2015 if current situation continues
