Finland's largest wind farm to date is to be built at a west-coast site at Tahkoluoto, near Pori by traffic fuel trader St1 Suomi, based in Helsinki. The company plans to use five 3 MW turbines, to be online in the first half of 2007. A turbine supplier is yet to be selected, although St1 hopes to make a final decision by the end of this year. "More of our customers want green energy and the wind farm project will secure the capacity we need to supply this market," says the company's Juha Kokko. Under its "electricity at market prices" product guarantee, St1 customers are offered the same retail energy prices wherever they live in Finland. When the Tahkoluoto wind farm comes into operation, it hopes to offer electricity at prices below those offered by conventional power plant operators. "St1 wants to be competitive in the electricity markets in Finland and in Sweden. Our decision to become a wind power producer is based on our strategy to build our own production base and to grow our market share within the area of green energy," Kokko says. It is the company' first wind power venture. It currently buys all of its electricity from NordPool, the Nordic power exchange.
