South Africa’s state-owned power utility Eskom on Wednesday said it had signed a new three-year deal to export electricity to Botswana.

Eskom, the sole power provider in South Africa, has struggled to meet power demand in the country in the past due to its ageing infrastructure. The utility now has excess capacity of 4,000 megawatts (MW) after new generation units were brought online and maintenance was carried out on power plants.

“Eskom reaffirms its position that we are ‘open for business’ and stand ready to undertake further long-term supply agreements,” Interim Eskom CEO Matshela Koko said.

South Africa signed a similar deal last month with its neighbour, Namibia.
