Kenya's KenGen plans 120 MW thermal plant by 2010

21st July 2009

Kenya Electricity Generating Company (KenGen) plans a fuel-powered electricity plant for 120 MW by 2010 to steer clear of outages, it said on Tuesday.

The utility produces 77% of Kenya's 1 296 MW power. Most of it is generated by hydroelectric dams but drought has depleted water levels and forced the company to shut down one station.

"To address the increasing power supply-demand imbalance, KenGen has been mandated ... to construct and commission a 110-120 MW thermal power plant on a fast track basis," the firm said in a newspaper advertisement.

"It is intended to develop the project under an Engineering Procurement and Construction or turnkey contract basis and that the plant would be operational by end of 2010."

KenGen said it was in the process of contracting a supplier and installer of the generator sets.

The new plant will be located in the coastal city of Mombasa, next to an already functioning station producing 75 MW from diesel-fired generators and another 60 MW by turbines turning on gas.

Kenya wants to ramp up production of environmentally-friendly energy by adding 2,000 MW of electricity from coal, geothermal, wind and clean coal sources.

whenever I see thermal plants..i know its bad news...thermal power is too expensive..but we have no option

What about the coal power station? Hope someone can get info on that project.

Kenya to build Africa's biggest windfarm

One of the hottest places in the world is set to become the site of Africa's most ambitious venture in the battle against global warming.

Some 365 giant wind turbines are to be installed in desert around Lake Turkana in northern Kenya – used as a backdrop for the film The Constant Gardener – creating the biggest windfarm on the continent. When complete in 2012, the £533m project will have a capacity of 300MW, a quarter of Kenya's current installed power and one of the highest proportions of wind energy to be fed in a national grid anywhere in the world.

Until now, only north African countries such as Morocco and Egypt have harnessed wind power for commercial purposes on any real scale on the continent. But projects are now beginning to bloom south of the Sahara as governments realise that harnessing the vast wind potential can efficiently meet a surging demand for electricity and ending blackouts.

Already Ethiopia has commissioned a £190m, 120MW farm in Tigray region, representing 15% of the current electricity capacity, and intends to build several more. Tanzania has announced plans to generate at least 100MW of power from two projects in the central Singida region, more than 10% of the country's current supply. In March, South Africa, whose heavy reliance on coal makes its electricity the second most greenhouse-gas intensive in the world, became the first African country to announce a feed-in tariff for wind power, whereby customers generating electricity receive a cash payment for selling that power to the grid.

Kenya is trying to lead the way. Besides the Turkana project, which is being backed by the African Development Bank, private investors have proposed establishing a second windfarm near Naivasha, the well-known tourist town. And in the Ngong hills near Nairobi, the Maasai herders and elite long-distance athletes used to braving the frigid winds along the escarpment already have towering company: six 50m turbines from the Danish company Vestas that were erected last month and will add 5.1MW to the national grid from August. Another dozen turbines will be added at the site in the next few years.

Christopher Maende, an engineer from the state power company KenGen, which is running the Ngong farm and testing 14 other wind sites across the country, said local residents and herders were initially worried that noise from the turbines would scare the animals.

"Now they are coming to admire the beauty of these machines," he said.

Kenya's electricity is already very green by global standards. Nearly three-quarters of KenGen's installed capacity comes from hydropower, and a further 11% from geothermal plants, which tap into the hot rocks a mile beneath the Rift Valley to release steam to power turbines.

Currently fewer than one-in-five Kenyans has access to electricity but demand is rising quickly, particularly in rural areas and from businesses. At the same time, increasingly erratic rainfall patterns and the destruction of key water catchment areas have affected hydroelectricity output. Low water levels caused the country's largest hydropower dam to be shut down last month.

As a short-term measure KenGen is relying on imported fossil fuels, such as coal and diesel. But within five years the government wants to drastically reduce the reliance on hydro by adding 500MW of geothermal power and 800MW of wind energy to the grid.

Not only are they far greener options than coal or diesel, but the country's favourable geology and meteorology make them cheaper alternatives over time. The possibility of selling carbon credits to companies in the industrialised world is an added financial advantage.

"Kenya's natural fuel should come from the wind, hot underground rock and the sun, whose potential has barely even been considered," said Nick Nuttall, spokesman for the United Nations Environment Programme. "After the initial capital costs this energy is free."

The Dutch consortium behind the Lake Turkana Wind Power (LTWP) project has leased 66,000 hectares of land on the eastern edge of the world's largest permanent desert lake. The volcanic soil is scoured by hot winds that blow consistently year round through the channel between the Kenyan and Ethiopian highlands.

According to LTWP, which has an agreement to sell its electricity to the Kenya Power & Lighting Company, the average wind speed is 11metres per second, akin to "proven reserves" in the oil sector, said Carlo Van Wageningen, chairman of the company.

"We believe that this site is one of the best in the world for wind," he said. If the project succeeds, the company estimates that there is the potential for the farm to generate a further 2,700MW of power, some of which could be exported.

First, however, there are huge logistical obstacles to overcome. The remote site of Loiyangalani is nearly 300 miles north of Nairobi. Transporting the turbines will require several thousand truck journeys, as well as the improvement of bridges and roads along the way. Security is also an issue as the region is known bandit country, and many locals are armed with AK-47 assault rifles.

LTWP also has to construct a 266-mile transmission line and several substations to connect the windfarm to the national grid. It has promised to provide electricity to the closest local towns, currently powered by generators.

Just noted, this 120mw plant was supposed to be operational by end of last year, did it get off the ground?
