The electricity use in Portugal (gross production + imports – exports – losses) was 51.2 TWh in 2008. Portugal imported 9 TWh electricity in 2008. Population was 10.6 million.[1] In 2014 electricity was generated by 30% hydroelectricity, 27% natural gas, 22% wind, 20% coal and 1% solar.[2]

Main power stations[edit]

Hydro[edit]

The pumped-storage hydroelectricity plant at Frades works as 880 MW for generation and 780 MW for pumping.[3]

Wind power[edit]

Portugal produced 11% of electricity with wind power in 2008[4] 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.[5]

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.[10]

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.[11]
