Folie 1
An identification of suitable zones to investigate for
development of both grid connected and offgrid solar and wind
projects Results are presented for 15 countries in West Africa, all
of which are part of the ECOWAS community
for solar and wind energy in West AfricaCalculation is simple,
and based on critical parameters such as grid proximity,
topography, resource quality, population density, land-cover and
protected areas
4. Results are presented as maps and numbers that indicate
technical potential Suitability Analysis

electricity tariffs on the islandSites were assessed for economic
feasibility using proprietary models developed by IRENASite
