Scaling Up Renewables Through Regional Planning and Coordination of Power Systems in Africa—Regional Power System Planning to Harness Renewable Resources and Diversify Generation Portfolios in Southern Africa
Tóm tắt
Southern Africa has an abundance of renewable energy resources, yet ~ 40% of its inhabitants do not have access to electricity. This paper summarizes the literature scan to understand the energy access challenge in the region, explores possible solutions, and examines the extent of planning and coordination at regional level aimed at exploiting energy from renewable energy sources and diversifying energy portfolios. The paper finds that the inhibiting factors are shortcomings in regional institutions and at government level, financial scarcity, inadequate grid, lack of interconnection among the member states, and a low skills base for renewable energy integration. The paper recommends empowering regional institutions to make binding decisions on regional energy planning; government commitment to renewable energy projects; innovative funding mechanisms; interconnecting all Southern African Power Pool (SAPP) countries; strengthening the existing interconnectors using high-voltage direct current (HVDC) and high-voltage alternating current (HVAC); accelerating renewable energy targets through hydropower, gradually increasing access by implementing off-grid, mini-grids, national grids, and eventually the regional SAPP grid; and improving skills in collaboration with countries that are experienced in renewable energy.
