Electricity sector in Portugal

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.[1]

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.[2][3][4]

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.[5]

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.[6]

Main power stations

edit

Hydro

edit

The pumped-storage hydroelectricity plant at Frades works as 880 MW for generation and 780 MW for pumping.[7]

Wind power

edit

Portugal produced 20% of electricity with wind power in 2017[8] 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.[9]

Solar power

edit

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.[14]

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.[15]
