African nations need to diversify energy supply, particularly countries reliant on hydropower, industry experts said at an energy conference in Johannesburg on Wednesday.
The region has been affected by severe droughts in recent years, affecting not only food security but also energy supply in countries that make heavy use of hydropower.
Low rainfall in Kenya, where electricity generation capacity is mostly from hydroelectric and geothermal sources, pushed the country to generate more electricity using costly diesel last year.
"You need a mix that allows you to mitigate those types of issues," said George Njenga, GE Power's regional executive for sub-Saharan Africa.
