While electricity is required for almost all modern economic activity, in Sub-Saharan Africa access to power is limited: over 640 million are not connected to power supplies (African Development Bank 2019). Continuation of a business as usual pace, alongside population increase, will see 530 million people still without electricity in 2030 (90 percent of global number). The overall goal in Africa is therefore to increase energy access as a critical enabler of resilience, which will generate economy wide benefits and harness the abundant renewable endowments in the face of falling prices of renewable energy (World Bank 2020). Additionally, in places where there is access to electricity, supply is often poor and failures can be exacerbated by changes in climate. For example, unusual recent extended droughts in the Zambezi River basin have resulted in prolonged periods of power shortages from its hydropower plants, which causes heavy economic losses (World Bank 2023b).
