South Africa’s power utility Eskom said on Tuesday the first unit of its Kusile coal-fired power plant has been connected to the grid, as it raises capacity to overcome electricity shortages in Africa’s most industrialised country.

Unit one of the Kusile plant will add 800 megawatts (MW) of power capacity. When fully completed, the plant will have total output of 4,800 MW, making it one of the largest coal-fired plants in the world, Eskom said.

Eskom has been in talks with Anglo American about supplying coal to the plant.
