GIS-BASED SUPPORT FOR BASED SUPPORT FOR IMPLEMENTING POLICIES AND
GISGIS-BASED SUPPORT FOR IMPLEMENTING POLICIES AND PLANS TO INCREASE ACCESS TO ENERGY SERVICES IN GHANA Ghana Geospatial Forum Movenpick Hotel, Accra, Ghana Henry Nii Arday Aryeetey Senior Programme Officer, Energy Commission-Ghana 4th March 2015 Presentation Outline 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. 5 Flow Diagram GIS Maps & Energy Access Modelling National electricity grid network Ghana Electricity Access Access to Electricity - Highest Access to Electricity - Lowest LPG Stations in Ghana 450,000 411,426 Population Per LPG Station 400,000 343,826 350,000 300,000 232,560 250,000 169,441 200,000 150,000 100,000 123,522 103,841 98,438 81,047 67,121 51,444 50,000 - Region Renewable Energy in Ghana 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 http://www.ghea.energycom.gov.gh/
