What is the African single Electricity Market (afsem)?
On June 3, 2021, The African Union oficially launched the African Single Electricity Market (AfSEM). This marked the commencement of an electricity market that connected the power supply infrastructure of the Union's 55 member countries. The goal is the development of one continuous eficient and afordable electricity market across the continent.
How reliable is Africa's electricity supply?
Electricity supply reliability remains a huge challenge for countries across Africa. Power rationing, outages, and grid collapses are huge fixtures for many markets. According to a 2022 survey by Afrobarometer, only 43% of Africans reported a reliable electricity supply, with significant variation across countries.
What is Africa's energy potential?
Africa has huge renewable energy generation potential. According to the Global Solar Atlas, the continent's average solar energy potential is 4.51 kWh/kWp/day, the highest of any region globally. Also, about 90% of the continent's hydropower potential remains unexploited— the largest proportion of untapped capacity globally.
How will Africa benefit from interconnected power grids?
Expanded electricity trade through a continent-wide interconnected power grid will link African countries' power networks ensuring that countries and regions that produce surplus energy can transmit it to regions with a power supply deficit.
