Generation

Power generation is the process of producing electric power from sources of primary energy. Energy resources can be classified in three categories namely renewable, fossil, and nuclear. Within the generation categories renewable comprise of wind, solar, geothermal, biomass, and hydropower. Fossil fuels include coal, petroleum, natural gas For utilities in the electric power industry, generation is the stage prior to the delivery of power to end users (transmission, distribution, etc.) or its storage (using, for example, the pumped-storage method). Electricity generation is carried out in power stations also called power plants.

Stiegler’s Gorge hydroelectric project would have regional advantage

[img:Outages%20d_0.jpg| ]15 February 2012 - For several decades the Stiegler’s Gorge hydroelectric project has been seen by Tanzania as a key component of that country’s hydropower master plan. This plan, completed during the mid-1980s, identified eight potential hydropower projects in the Rufiji Basin.

These potential projects were Ruhidji (685 MW), Mnyera (485 MW) Kihansi (240 MW), Mpanga (165 MW), Iringa (80 MW), Lukose (130 MW), Kilombero (464 MW), and Stiegler's Gorge (2,100 MW). Only Stiegler's Gorge was taken to feasibility study stage.

Eskom’s unplanned outages lower

[img:Power%20SA.thumbnail.JPG| ]14 February 2012 - South Africa’s under pressure power generation network, while still tight, is experiencing some relief due to a lower volume of unplanned outages. This figure stood at 2,820 MW on Monday the 13th of February 2012, having exceeded 5,000 MW earlier in the month.

The utility has also been aided by the cooperation of some large ferrous metal companies that have taken smelters offline to alleviate some of the pressure on the national grid. At the beginning of the week of the 13th February, the utility had 35,427 MW available to meet demand of 31,593 MW. Current planned maintenance stands at 4,840 MW.

.]Johannesburg, South Africa --- ESI-AFRICA.COM --- 01 February 2012 - South African national power utility Eskom Holdings has registered concern about the security of coal supply beyond 2018, saying its suppliers are more interested in the higher paying Asian export markets.

Spokeswoman Hilary Joffe said that although current coal stockpiles were healthy at just over 40 days’ supply, new supplies after 2018 were not secured. “We are concerned about the security of supply beyond 2018. Investments should already be happening to provide mining capacity for coal we are going to need in the long term because our stations’ lives are 40 to 50 years,” she added.
