Portugal's installed wind capacity has now reached 80 MW following last month's 2.25 MW extension to the Maçao plant in Serra da Laze in central Santarém. Maçao I came on line in July 1999 using three 750 kW NEG Micon turbines, which have now been doubled in number to produce a total of 4.5 MW. Total investment is about ESP 805 million. The developer, Enervento -- an independent Porto-based company -- has also been given the go ahead to install a 5 MW wind plant in the northern district of Arouca, which should come on-line by the end of the year, according to Enervento's Aurelio Tavares. By the end of 2001 Tavares expects Enervento to have installed a total of 20 MW of wind ower. There are long term obstacles to further wind growth in Portugal in sight, however. Tavares says that Portugal lacks clearly defined regulations on grid connection regulation. As a result, there are a growing number of speculators manoeuvring to grab remaining development rights, with a view to selling them to the highest bidder.
