Production

During the first nine months of 2019, renewable energy sources have represented 51.9% of the electricity production mix in mainland Portugal.

Electricity produced in September (3,472 GWh) accounted for only 89.1% of the continent's electricity consumption, with 51.8% resulting from renewable power plants. 

From January until December of 2018, renewable energy sources accounted for 31.1% of the overall electricity production of the Autonomous Region of Madeira.

From January until December 2018, renewable energy sources accounted for 39% of the overall electricity production of the Autonomous Region of Azores.

The greater use of Portuguese endogenous and renewable resources for the production of electricity has altered the composition of the electricity production mix in Portugal and has, consecutively, played an increasingly important role in the satisfaction of consumption.
