Calculations based on data from Portuguese grid REN show the share of renewable electricity in 2009 increased to 36.5%. But this figure increases to 41.7% once annual variations in hydro capacity are factored in, says Quercus. Hydropower is one of Portugal’s main sources of renewable energy.

Portugal’s non-binding target for 2010 under the 2001 directive on renewable electricity is 39%. A European Commission progress report published last year showed many member states including Portugal were not on track to meet their targets. The report is based on 2006 data.

Electricity – supply and demand

Demand grew by 4.4% a year from 1997-2007, higher than the rate of economic growth (though electricity demand growth slowed after 2005). In 2007, electricity production decreased by 3.6%. Portugal is connected to the Iberian electricity network. 38% of electricity in Portugal is used by industry, 31% by commerce and 28% by households (see IEA figures).
