In 2008, Net electricity use in Portugal (gross production + imports – exports – losses) was 51.2 TWh. Portugal imported 9 TWh electricity in 2008. Population was 10.6 million.IEA Key energy statistics 2010 Page: 27, 54

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.https://www.iea.org/reports/monthly-electricity-statistics see: Downloads → Revised historical data

By 2023, the share of renewable power sources of Portugal's electricity rose to 61% (from 49% in 2022). 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.

Main power stations

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.EWEA Annual statistics 2010

Solar power

In Lisbon, the energy payback time (see also EROEI) in the roof top solar photovoltaic (PV) 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.Compared assessment of selected environmental indicators of photovoltaic electricity in OECD cities European Photovoltaic Industry Association (EPIA) 5/2006

Transmission

Redes Energéticas Nacionais manages the high voltage power lines.

In 2014, Portugal had an electricity interconnection level (international transmission capacity relative to production capacity) of 7%, below the recommended 10% level.COM/2015/082 final: "Achieving the 10% electricity interconnection target" Text PDF page 2-5.
