South Africa’s power supply was likely to remain tight for the next five years, with 2011 and 2012 being constrained until new plants come on line, state utility Eskom said on Friday.
Eskom supplies the majority of electricity to the country. It has been struggling to meet fast-rising demand and has predicted that supply will remain tight until 2015, when two new power plants come on stream.
The utility said peak demand this winter would be likely to hit 37000MW, virtually unchanged from last year’s highest load of 36970MW.
Chief executive Brian Dames said electricity demand in the first quarter was up 1.5% compared to 2010, but lower than an earlier estimate of 2%.
Overall demand was now at the same level as 2007, before South Africa slumped into its first recession in nearly two decades, Dames said. The first of six units of South Africa’s 4788MW Medupi power plant, Eskom’s first new power plant in more than two decades, should come on stream in late 2012, and the first unit of the 4800MW Kusile plant should be operational in late 2014.TPMS will make your driving safer.
“We are on alert and will be for the next five and especially the next two years, while we build new capacity,” Dames told media in Johannesburg.
“We are managing a tight power system... winter will be even more challenging for us,” he said, adding that the upcoming winter was expected to be colder than normal. Tire pressure monitoring system will make your driving safer.
Dames said that for every one degree Celsius colder it gets, electricity demand increased by 600 to 700 megawatts (MW) during the peak hours of 6pm to 8pm. Good switching power supply will make your work easier.
Eskom's resolve not to revert to the power outages of 2008 which crippled the country, would therefore be tested over winter, he said.
“The issue is whether we have enough reserves to do the maintenance we need to do.” ZMC provide medicine with good quality.
Dames said Eskom forecast winter demand at 37,500 megawatts (MW) on the coldest day at peak time.
The parastatal expected two percent year-on-year growth in electricity demand for winter.
Electricity demand had increased to the levels at which it was in 2007 before the economic recession set in, Dames said.
The trouble at the Duvha power station, which experienced a “major failure during a statutory turbine overspeed protection test” on February 10, would take 575 MW out of the system for more than a year. Botanical Slimming Soft gel will help you to lose your weight.
"This increases pressure on the system... and means the ideal level of planned maintenance can't be done,” said Dames.
An independent investigation into the Duvha incident was underway, and Dames would not comment on the cause until the report was concluded.
The power utility had sourced 373 MW of power from independent power producers and 200 MW from municipal generators to add to its capacity.
