International power grids/ exchanges:
An important strategy for exploiting the variability of renewable energy is to spread the electricity supply and demand over large areas. Large catchment areas with multiple nodes of concentrated supply and demand, allow flexibility in the system.
African Clean Energy Corridor
The African Clean Energy Corridor (ACEC) programme was launched by IRENA in 2014 to meet the huge increase in energy demand projected in the African continent while fulfilling climate objectives. The initiative will be taken up in three regions: the Eastern Africa Power Pool (EAPP), the Southern African Power Pool (SAPP) and the West Africa Clean Energy Corridor (WACEC). A regional approach to power sector development will enable the trade of least-cost renewable and clean electricity, and an optimal utilisation of renewable energy. ACEC will involve the following steps: 1) zoning and resource assessment to site renewable power plants in areas with high resource potential and suitable transmission routes; 2) national and regional planning to integrate cost-effective renewable power options; 3) enabling frameworks for open markets and reduced financing costs; 4) capacity building to plan, operate, maintain and govern power grids and markets; and 5) public information and awareness outreach.
