Eskom will ask the National Energy Regulator for an electricity tariff increase of 25.3 percent from 1 July.
The request for a much larger than expected tariff hike reportedly has the backing of Government’s so-called “war room”.
S&P downgrades Eskom credit rating to junk
Ratings agency S&P has downgraded Eskom’s credit rating to BB+.
The announcement came late on Thursday and will cause a spike in the cost of borrowing for the beleaguered utility.
S&P also put Eskom on a "negative outlook," citing last week's unexpected suspension of Eskom CEO Tshediso Matona and three other senior executives.
The ratings agency says it doesn't have confidence in government's support plan and that Eskom's operating performance hasn't stabilised because of a spike in costs and the extremely tight generation capacity margin.
