Preliminary data from the Spanish grid operator, Red Electrica de Espana (REE), reveals a remarkable increase in renewable energy's contribution to Spain's total electricity production in October. Renewables accounted for 50.7% of the country's electricity generation, representing a substantial uptick from the 42.1% recorded the previous month.
Renewable sources generated 10,609 GWh of electricity in October, marking a notable year-on-year increase of 25.5%. Notably, on October 20, Spain achieved an unprecedented renewables share of 70.5% in its daily electricity production, propelled primarily by wind power generation. This record was surpassed on November 2, with renewables contributing 73.3% to the daily power mix.
Wind energy played a significant role, representing an average of 28.1% in Spain's total power mix for October, surpassing combined-cycle gas turbine plants and nuclear power. Wind farms in Spain generated 5,888 GWh during the month, exhibiting a substantial improvement from the 3,600 GWh recorded the previous month.
On October 26, wind power made history by accounting for 54% of Spain's daily electricity production, marking its highest share in the daily generation mix, according to REE.
Solar photovoltaic plants, however, contributed 12.3% to the overall electricity mix in October, down from 16% in September.
Spain's electricity demand in October was estimated at 19,806 GWh, reflecting a 2.5% annual increase in gross terms. When adjusted for working hours and temperatures, demand rose by 1.3% year-on-year.
