Spain's renewables generated 9,249 GWh of power in June, increasing production levels by 8.4% compared to the same period a year prior, Spanish grid operator Red Electrica de Espana (REE) said in its latest monthly estimates report.

This level of output brought the renewables share in the total production to 46.3%, down from 50.7% reached in May, as REE estimated at the time.

Wind farms, Spain’s top source of renewable power, finished June with the combined output of 3,672 GWh, up 9.8% year-on-year. The share of wind was very close to that of nuclear power and combined cycle power plants.

Production from solar farms rose by 28% on the year to 2,296 GWh.

More details are presented in the following table:
