Water and wind synergies found in new plant

Installation of three 750 kW turbines near an existing 6.4 MW hydro station at Alto Tamega in northern Portugal will allow the German developer, Harpen, to sell the power at a premium green tariff rate to national Portuguese utility EDP. The country has a 12 year green tariff arrangement giving a return which averages EUR 0.05-0.06/kWh, says Harpen's Peter Klingenberger. Harpen already owns the hydro facility, one of three hydro plant that it owns and operates in the country. "We will achieve real synergy benefits because the wind station will use the same 24 kilometre, 60 kV cable that transmits power from the hydro station to the national network," says Klingenberger. The company has all the necessary building permits in place and a tender for turbine supply will close in the summer. "We have to decide fast because manufacturers have delivery periods of up to 12 months and we want to install the turbines before the end of 2001,"he says. The wind station will be operated by Altberg, a company founded by Harpen and named after the region in northern Portugal where the station is situated.
