Enernova, subsidiary of Portuguese utility group Electricidade de Portugal, has short-listed four turbine manufacturers for a 10 MW wind station to be erected near Serta. The company, based in Lisbon, will ask the companies -- which it declines to name -- for bids within the next two months, says Domingos Inacio de Costa of Enernova. The company already operates a 10.2 MW wind station of Danish Vestas machines and a 10 MW wind plant of German Enercon turbines, both situated close to Vila Lobos. It plans to install at least two additional wind farms of about 10 MW each by the year 2000, says de Costa. Any further development hinges upon how European energy ministers adopt the proposals included in the EU White Paper on renewable energies, he adds (Windpower Monthly, January 1998). If hydro plant above 10 MW are included as an element in the plan to double renewables, de Costa says, it will probably be chosen over wind power for new development. Meantime, the Portuguese government is considering raising the rate of payment for wind generated power, he says. At the moment the figure is about PTE 10.3/kWh -- compared to PTE 13-14/kWh paid in Spain and PTE 18/kWh in Germany. Wind potential in Portugal amounts to about 300 MW, exploiting sites where wind speeds are around 7.5 m/s at 30 metres height, according to Enernova.
