Addressing a fund-raising dinner for the ruling African National Congress night, Mbeki said his government should have heeded pleas by state power utility Eskom several years ago to invest more in electricity generation to keep up with country's economic growth.
"When Eskom said to the government: 'We think we must invest more in terms of electricity generation', we said no, but all you will be doing is just to build excess capacity," Mbeki said in comments broadcast on public radio.
"We said not now, later. We were wrong. Eskom was right. We were wrong."
Mbeki's rare public apology comes at a time when the country is experiencing the worst power cuts in years, forcing Eskom to start rationing electricity this week as part of a programme that should last until the end of the week.
The rationing has led to a raft of complaints from businesses and retailers in the build-up to Christmas, while traffic jams are a common sight with many traffics lights out of action.
