Government officials from Botswana will meet with South Africa’s electricity ministry this week after power-import costs more than doubled, worsening a supply crisis. Breakdowns at Botswana’s main plant, the 600 MW Morupule B facility, have caused blackouts that last as many as four hours. South Africa’s state-owned power company fills the shortfall, but Eskom Holdings SOC Ltd. has raised tariffs significantly, Botswana’s energy minister, Bogolo Kenewendo, told lawmakers Monday.
