WINDHOEK – The national energy utility, Nampower, yesterday, issued a ‘critical’ status alert on the electricity supply situation in the country, with an appeal for households to immediately implement electricity saving measures during peak periods.
s 350 MegaWatts, and Nampower yesterday said the appeal to households is to conserve at least 10 percent of the average consumption.
“Given this situation, we wish to remind our customers and the nation at large that the electricity supply situation remains critical,” Nampower spokesperson Monica Nashandi said in a statement yesterday.
Eskom issued its warning earlier as the recent heat crippled some power plants making them unable to operate at full capacity, because they could not cool their water fast enough.
However, this week Eskom said the arrangements it made with large power consumers would be sufficient to manage capacity and avoid large scale load-shedding, as experienced in 2008.
“Nampower wishes to inform the public that the system of one of its regional suppliers and transmission partners, Eskom is currently under severe constraint, due to the loss of additional generating units from their power stations and the extensive use of emergency reserves. The situation has prompted Eskom to declare an emergency,” Nashandi said. Yesterday Nampower said it would “continue to do everything in its power to ensure security of supply.”
“We appeal to all our customers and the nation at large to continue implementing electricity saving measures such as switching off air-conditioners, geysers and swimming pool pumps and all other non-essential appliances during peak times – which is eight to ten in the morning and six to nine in the evening – to reduce the demand,” Nashandi said.
She further said despite local and regional power supply challenges, Nampower has continued to provide uninterruptable electricity supply to the nation. Nampower is currently supplying the country through its local generation sources, in addition to imports.
Nampower is currently importing 110 MegaWatts from South Africa, “but strictly from 06h00 in the morning up to 17h00 in the evening. The average hourly Eskom import during these hours is approximately 110 MegaWatts.
The period with the highest risk for Namibia is from 17h00 pm to 21h00pm, therefore during these hours the import from Eskom is zero MegaWatts in order to minimize the risk to Nampower,” the energy utility said yesterday.
Nampower also has power-sharing agreements in place to import 150 MegaWatts of electricity from the Zimbabwe national energy utility, 50 MegaWatts from Zambia’s energy utility and 115 MegaWatts from the energy utility of Mozambique.
