The wind energy sector achieved a maturity status within the Portuguese power system. In 2017, Portuguese wind farms produced 12.3 TWh, meeting 24.0% of the nation’s electricity demand with wind energy. For the third consecutive year, wind energy covered more than 100% of the electricity demand during certain hours, without any technical problems reported by the Portuguese Transmission System Operator (TSO). The instantaneous and daily electricity demand met by wind energy achieved new records during the year as well: 110% and 82%, respectively.
For the first year since wind energy capacity was deployed in Portugal, no additional wind power capacity was deployed, although repowering of some wind farms has occurred to maintain the installed capacity.
The total installed wind power capacity at end of 2017 was 5,313 MW, which represents 38.6% of the total renewable operational capacity in the country. A new paradigm is emerging in Portugal, with the first licensing requirements to deploy wind farm projects without feed-in tariff.
