Portugal can easily achieve its EU target for 31% of its total energy consumption to be met by renewable sources by 2020, but only if it increases its goal for renewable energy in the electricity supply mix from the current 45% by 2010 to 60%, says António Sá da Costa of the Portuguese renewable energy association. Around a third of the 60% mix would come from wind plant, he says, with hydro accounting for slightly more, and a quarter of it made up of small hydro, biomass, solar and wave plant. He also calls for higher power purchase prices for wind-generated electricity. "Over the past four years, the price of equipment has increased by fifty per cent and network operators require that generators are capable of supporting the instability of the electricity network," he says. "This imposes the installation of control equipment and the observing of other sets of rules that increase the cost of the equipment."
