Generation, solar thermal

Solar thermal electricity generation was 10.8% lower than in 2024.

Annual share of solar thermal generation in total generation

Andalucía and Extremadura are the autonomous communities with the highest solar thermal generation, together accounting for over 85% of this generation.

July was the month with the highest generation, with a value 2.1% lower than July of the previous year, which also marked its monthly peak. The seasonality of this technology is similar to that of photovoltaic, although its daily electricity generation is distributed more evenly throughout the day due to the capacity of these power plants to store part of the heat they obtain from the sun and use it in later hours.
