The wind energy sector reached a maturity status within the Portuguese power system in 2016. The country deployed an additional 279 MW of wind power capacity—representing the highest value since 2012. Portugal reached a total of 5,313 MW installed wind power capacity, which represents 40% of the total renewable operational capacity in the country.
In 2016, Portuguese wind farms produced 12.5 TWh, meeting 24% of the nation’s electricity demand with wind energy [1–5]. For the second consecutive year, at certain hours wind energy covered more than 100% of the electricity demand without any technical problems reported by the Portuguese Transmission System Operator (TSO). The electricity production from renewable energy sources in 2016 reached 66% of the national consumption, and during four consecutive days in May, continental Portugal met 100% of its electricity needs with renewables.
The high contribution from endogenous resources enabled Portugal to reduce their dependency on foreign energy and exports exceeded imports for the first time since 1999.
