Zimbabwe’s industrial power users have secured $250-million from the African Export-Import Bank to build floating solar panels at the world’s largest man-made lake. The Intensive Energy User Group, made up of mining companies including a former local unit of Rio Tinto and Mimosa, plan a 250 MW plant at the Kariba Dam to be implemented in 18 months, according to a copy of its presentation seen by Bloomberg. That can be expanded to 1 GW of solar capacity.
