As with Spain, this contrasts starkly with earlier performance — wind power penetration from Portugal's 4.73GW of cumulative wind capacity rose to 23.2% of generated power, from 19.8% in 2012.
The Portuguese coalition government has a pro-renewables stance but is under pressure from the European Commission to address its energy tariff deficit as part of the country's bailout agreement.
Last year, the government negotiated a voluntary agreement with wind-farm operators in return for regulatory stability. Income from existing and licensed wind capacity was reduced by EUR140 million up to 2020, with feed-in tariffs averaging EUR70/MWh. However, APREN believes the regulatory climate is not sufficiently stable to attract investment.
Portugal's wind-energy market now hangs entirely on the 800MW remaining from the previous government's wind-licensing allocations. Finance availability is a braking force but APREN's Antonio Sa da Costa expects capacity to advance at "a steady pace". That will serve the wind market until the end of the decade, when Iberian interconnections with France are completed, he adds.
