August 3 (Renewables Now) - Spain produced 46.1% of its electricity from renewable energy sources in July, Spanish grid operator Red Electrica de Espana (REE) said in the latest estimates report.

The share of renewables in the total generation came down just slightly from the 46.3% achieved in June.

The nation's green power production reached 10,411 GWh, up by 13.4% compared to July 2020.

Wind farms generated 4,279 GWh in July, which represented an increase of just 0.7% year-on-year.

Spain’s solar PV output rose by 35.4% on the year to 2,576 GWh, reaching the highest level of production since REE started keeping records in 2007, the grid operator said.

Nuclear energy led Spain’s electricity mix in July with a 22.7% share in the total production, followed by wind power with 18.9%. In the January-July period, the combined share of wind surpassed that of nuclear power.
