Electricity sector in Portugal
In 2008, Net electricity use in Portugal was 51.2 TWh. Portugal imported 9 TWh electricity in 2008. Population was 10.6 million.
In 2018 electricity was generated by 23% hydroelectricity, 26% natural gas, 22% wind, 20% coal, 5% biomass, 2% solar and 2% oil. In 2019 electricity was generated by 19% hydroelectricity, 32% natural gas, 26% wind, 10% coal, 6% biomass, 2% solar, 2% oil and 1% other combustibles.
By 2023, the share of renewable power sources of Portugal's electricity rose to 61%. Grid operator REN attributes the record percentage to favorable weather conditions.
Portugal aims to generate 85% of its electricity from renewables by 2030 and achieve carbon neutrality by 2045, five years ahead of its initial target.
Hydro
The pumped-storage hydroelectricity plant at Frades works as 880 MW for generation and 780 MW for pumping.Wind power
Portugal produced 20% of electricity with wind power in 2017 and had the average year capacity of 14% of wind power in the end 2010. Wind power capacity was 3,357 MW in end 2009 and 3,702 MW in end 2010.Solar power
In Lisbon, the energy payback time in the roof top solar photovoltaic technology is less than 2 years and less than in Sydney, Munich, Athens or Barcelona, but some more than in Madrid, Los Angeles or Ankara.Transmission
Redes Energéticas Nacionais manages the high voltage power lines.In 2014, Portugal had an electricity interconnection level of 7%, below the recommended 10% level. Exchange only occurs with Spain.
