Spain’s renewable energy output is on track to reach 135,048 GWh this year, surpassing last year’s total of 134,649 GWh, which set the country’s annual record, according to the Transmission System Operator (TSO). This impressive growth reflects a broader trend towards sustainability, with renewable sources now accounting for 56% of total power generation—up 13% from the previous year.
Significant Capacity Additions
From January to October 2023, Spain added 5.9 GW of green capacity, approaching the 6.5 GW of renewables connected throughout the entire year. The country aims to double its installed renewable capacity to 160 GW by 2030, highlighting its commitment to clean energy.
Record Wind Power Generation
The surge in renewable output is largely driven by wind energy, which reached a record high of 434 GWh (or 18.1 GW/day) on a recent Thursday. On that day, green energy sources covered 66% of Spain’s power mix, with wind energy alone contributing 52% of total generation.
Solar Energy Milestones
Spain’s solar power also marked significant achievements, including a record daily production of 212 GWh (or 8.8 GW) on July 12. Moreover, March saw a monthly record of renewable generation at 14,404 GWh, while April recorded the highest green share in the power mix at 64.4%.

Future Projections
Looking ahead, the TSO projects that renewable generation will exceed conventional generation in Spain for the second consecutive year in 2024. This trend underscores Spain’s ongoing transition towards a more sustainable and resilient energy system.
Conclusion
Spain’s renewable energy sector is flourishing, with record outputs in wind and solar generation. As the country continues to invest in green technologies and infrastructure, it is well-positioned to meet its ambitious energy goals and lead the way in the global energy transition.
