Africa’s biggest wind farm set for Kenya

SOUTH HORR, Kenya — Tumbling down to the jade waters below, the rugged hills around Lake Turkana in northern Kenya are made of boulders and lava stone.

This is a remote, lunar landscape and the site of what will one day be Africa’s largest wind farm.

A consortium of European and African companies is preparing to put up 365 wind turbines in a 165 km stretch of this desolate area inhabited only by semi-nomadic pastoralist herders.

As yet, there is little sign of the project. The hills appear untouched by humans, except for nine masts set up to measure the wind that surges between the Kulal and Nyiro mountains.

This wind, which rises over Lake Turkana before dying out over the Sahara, blows at an average speed of 11 metres per second and is a dream for any engineer working in wind energy.

“In Turkana, the wind speed and also the consistency provides for optimum conditions for wind power — in fact they are better than North Sea offshore wind power,” said Achim Steiner, executive director of the Nairobi-based United Nations Environment Programme.

“Here you can produce wind power at an interesting cost, without subsidies,” unlike the case in Europe, said Carlo Van Wageningen, chairman of the Lake Turkana Wind Power (LTWP) consortium.

LTWP has entered into a contract to sell the power produced to utility firm Kenya Power over 20 years at a cost of 7.52 euro cents/kwh, a much lower price than that paid for the hydro-electric power mainly used today.

If everything turns out well, the Turkana project will be a poster child for sustainable development — the notion that growth can be clean and improve life for the poor. Green groups, businesses and politicians are heading to Rio de Janeiro this month to give the doctrine a push, culminating with a UN summit on June 20-22.
The project all started when a Dutchman had to continually struggle to stop his tent getting blown away by the wind during a camping trip to Turkana.

He recounted the experience to a compatriot who specialised in wind energy — and so set the ball rolling on seven years of studies, financial negotiations and setbacks.
The financial backing is now secured, with only risk guarantees from the World Bank lending agencies Ida and Miga remaining to be finalised.

Once the green light is given on those, potentially by this August, then work can begin.

“All the contracts are in place. We’re ready to start,” Van Wageningen said.

The first step will be to build 204 kilometres of road to allow lorries to make the 12,000 round-trips needed to deliver all the necessary materials from Mombasa at one end of the country to Turkana at the other.

The turbines will be erected in one year, at the rate of one per day, and the first kilowatts of electricity should be delivered to the grid by the end of 2013.

By the time it reaches its full capacity, penciled in for the end of 2014, the site will produce 300 MW of electricity.

“We will represent about 20 per cent of the national electricity production” said Chris Staubo, a director at LTWP.

The project will cost 585 million euros ($728 million), plus an additional 142 million euros needed to build 428 km of high tension power lines linking the wind farm with the country’s main power transformer at Suswa. — AFP
