On that day, wind power led the renewable energy mix, producing 256 GWh and contributing 45.8% of the total output. Solar energy generated 151 GWh, accounting for 27%, while hydroelectric sources provided 129 GWh, or 23.1%. Solar thermal contributed 11 GWh, representing 2%, and other renewable sources added 11 GWh, or 1.9%. Renewable waste generated 1 GWh, making up 0.2% of the total.
At 11:15 a.m. on April 16, wind and photovoltaic (PV) sources together produced 100.63% of Spain’s electricity demand, a historic first for the nation’s energy system. Notably, this achievement occurred on a weekday, distinguishing it from previous renewable energy milestones.
Red Eléctrica highlighted the growing role of renewables, stating: “This milestone demonstrates the strength and reliability of Spain’s renewable energy infrastructure in meeting national electricity needs.”
On April 21 at 1:35 p.m., solar power set a new record for instantaneous power generation, reaching 20,120 MW. This surpassed the previous record of July 12, 2024, by 0.7%. At that moment, solar accounted for 61.5% of the national energy mix and covered 78.6% of the country’s electricity demand.
A Red Eléctrica spokesperson noted: “The record-breaking solar output on April 21 underscores the rapid advancements in Spain’s solar capacity and its critical contribution to our energy system.”
These achievements reflect Spain’s ongoing commitment to expanding renewable energy infrastructure. The combination of wind, solar, hydroelectric, and other renewable sources has enabled the country to meet its electricity needs sustainably, reducing reliance on non-renewable sources. The milestones on April 16 and April 21 highlight the increasing efficiency and capacity of Spain’s renewable energy sector, positioning it as a leader in clean energy adoption.
The successful integration of renewables into Spain’s grid supports the country’s broader environmental goals, ensuring a stable and sustainable energy supply for its peninsular system. These developments pave the way for further advancements in renewable energy utilization across the nation.
