Spain generated 53% of its electricity from renewable sources in September 2024, according to provisional figures from national grid operator Red Electrica de Espana (REE). This marks a slight increase from the 52.6% share recorded in August, demonstrating a consistent rise in renewable energy generation as the country works towards its clean energy targets.
Renewable electricity production for the month totaled 11,513 GWh, representing a 33% year-on-year increase. This growth reflects continued expansion in renewable capacity, particularly in wind and solar power. Despite the overall increase in renewables, the contribution from solar photovoltaic (PV) decreased in September after leading Spain's energy mix for the previous four months. Solar PV's share fell to 19.5%, while nuclear power took the largest share of the mix at 22.9%, and wind power contributed 21.1%.
The dip in solar output is attributed to the transition into autumn, which brings shorter daylight hours and less favorable conditions for solar generation. Wind energy, on the other hand, remained steady, benefiting from more consistent seasonal wind patterns, keeping it as a major contributor to the country's renewable energy output.
Spain's total electricity demand rose by 1.2% compared to September 2023, reaching an estimated 19,831 GWh. When adjusted for temperature fluctuations and working hours, the increase was 3.1%, reflecting a notable rise in demand driven by both residential and industrial sectors. This growth in demand comes as Spain continues to expand its renewable energy capacity while navigating fluctuations in conventional energy sources.
