JOHANNESBURG, Jan 7 (Reuters) - Two generators run by South Africa's power utility Eskom failed on Wednesday, a situation that has significantly increased the risk of power cuts in Africa's most advanced economy, a spokesman said.
Andrew Etzinger told Reuters there were "no reserve margins at the moment" and that there was a "60 to 70 percent chance" that rolling blackouts would have to be implemented as a result.
He also said that if the cash-strapped utility was unable to purchase crucial diesel supplies for its gas-fired power stations, Eskom would lose 5 percent of its capacity and blackouts would then occur on an almost "daily basis". But that was a "worst-case scenario", he stressed. (Reporting by Zandi Shabalala and Ed Stoddard)
