According to data from Associacao de Energias Renovaveis (APREN) in Portugal, a renewable record was set in March 2018, with renewable electricity production surpassing the demand of mainland Portugal.

This resulted in electricity prices on the Iberian wholesale market being reduced by 10%, an export electricity balance of 878 GWh, and emission of 1.8 million tons of CO2 avoided. Portugal exports electricity to Morocco and France.
