Johannesburg, South Africa — ESI-AFRICA.COM — 16 January 2012 – South African national power utility Eskom Holdings says it needs people to cut their power usage by 10% to keep the country’s electricity supply running.
“We urge all South Africans to partner with us to keep the lights on,” Eskom said in a statement.
“If all our customers can save 10% off their electricity usage, this will make it significantly easier to manage the power system during this challenging time.”
Eskom previously warned that the power system this year would be particularly challenging, and said it would issue news bulletins on the state of supply.
Available capacity to meet last Thursday’s peak demand was 34,618MW, while demand was forecast at 31,168 MW. Current planned maintenance stood at 4,461MW, with unplanned outages at 3,678 MW.
On Wednesday, peak demand of 31,108MW was met by available capacity of 32,601MW, and on Monday peak demand of 30,282MW was covered by available capacity of 30,742MW.
Peak demand for the rest of last week was forecast at 31,303MW on Friday, 29,762MW on Saturday and 29,205MW on Sunday.
The performance of the system had improved since last Monday, but during the course of Wednesday, the supply from Cahora Bassa, in Mozambique (1,500MW), was lost for approximately two hours, Eskom said.
Although supply was restored, the system remained constrained and customers were reminded to use electricity as efficiently as possible.
