Nov 23 (Reuters) - South African power utility Eskom reported a surge in first-half profit on Tuesday, boosted by higher power tariffs, and said it had secured the necessary funding to build much-needed power plants. [ID:nLDE6AM0QG]
Below are details of Eskom's generating capacity.
CAPACITY AND SHORTFALL
* Eskom has a total net maximum capacity of nearly 41,000 megawatts (MW).
* It operates 13 coal-fired stations and Africa's only nuclear-powered plant along with other smaller stations.
* Eskom, established in 1923, generates 95 percent of South Africa's electricity and 45 percent of Africa's electricity.
* In January 2008, the utility said it was unable to supply power to the country's mines, sparking a major energy crisis, which cost the country billions of dollars in lost production.
* Eskom plans to invest 440 billion rand ($62.56 billion) in new power plants over seven years. Some plans had been delayed as the utility struggled to find all the funds needed.
* The expansion programme is funded from Eskom's balance sheet, power tariffs and government support which includes 350 billion rand worth of guarantees, a 20 billion rand equity injection and a loan of 60 billion rand. In addition, Eskom has secured funding from international institutions, including a $3.75 billion loan from the World Bank.
* Eskom said South Africa would need to add 50,000 MW of new supply to meet rising demand and to replace ageing plants.
* Eskom has said South Africa's power supply is expected to be tight until 2015, and especially between 2011-12.
* The government is drafting a new energy supply plan which could see South Africa halving its reliance on coal by 2030, with nuclear and renewable energy playing a bigger role in plugging its power deficit. The plan is expected to be finalised and made into law by early 2011.
PLANNED POWER STATIONS
* Eskom started construction on the 4,788 MW Medupi power station in 2007. The first of six units is due in 2012.
* The first unit of the 4,800 MW Kusile plant is due 2014.
* The 1,352 MW Ingula hydro-power station is due in 2014.
* The utility has invested in a wind farm with 50 wind turbines providing 2 MW of electricity each.
* The mothballed Camden power station has been recommissioned and is now fully operational; the Grootvlei and Komati power plants are also being brought back to service.
