This month, 19 resolutions were published in the BOE for solar-wind hybridisation and storage projects. In addition, 115 MW of wind capacity were rejected, corresponding to Repsol and Aspiravi.

The public hearing begins on the draft royal decree regulating investment plans for electricity networks.

Sara Aagesen chaired the presentation of the results of the PRTR (Plan for Investment in the Ecological Transition), held at the Madrid College of Architects. The ministry recognizes 39 exemplary initiatives in the implementation of the Recovery, Transformation and Resilience Plan.

Grid saturation is leaving no capacity for new industries and electrification projects, hindering stand‑alone batteries and putting downward pressure on PPAs. Experts are calling for urgent measures to enable flexible connections and accelerate investment in networks.

The publication of firm demand capacity maps confirms that 83.4% of nodes are saturated and shows 0 MW available in key substations, constraining new industry, renewables and green hydrogen. The sector is calling for flexible connections and investment in networks with clear rules from CNMC and MITECO.

Methane accounts for 18.62% of net emissions in Spain and is 84 times more potent than CO2 over 20 years. Environmental groups and experts are calling for an intersectoral plan to boost renewables and curb dependence on gas.

The MITECO is processing seven renewable projects from Iberdrola, Boreas Energy, Naturgy, Siemens Gamesa and Sistemas Energéticos, involving hybridisation, batteries and repowering in Cáceres, Burgos, Aragón, Navarra, Ciudad Real and Zaragoza.

An official chart shows a sustained rise in technical curtailment since May. Experts warn that without grid reinforcements, storage and demand management, renewable projects will lose financial viability.

52.4% of our country’s electricity production in August was renewable, and 74.1% did not emit CO2 equivalent. Solar photovoltaic has covered a quarter of demand and is once again the top technology in the mix for the fourth consecutive month, with production 8.5% higher than in August 2024.

The financial markets reflect the boom in renewables in Spain: in 2025 more than 56% of electricity generation comes from these sources, with Solaria rising by 10% and drivers such as Acciona Energía and Iberdrola diversifying and modernising.

AEGE’s Energy Barometer reveals that electro-intensive consumers in Spain face significantly higher costs than their European competitors, due to exclusive system adjustment charges and lower indirect CO₂ compensations.

In the last week of August, projects by Statkraft, Naturgy, Enel, Elawan and Villar Mir were approved, while two wind farms promoted by Forestalia in Zaragoza were rejected.
