AEGE’s managing director, Pedro González, analyses the impact of the validation of the 80% discount on grid levies until July and stresses that only a wider deployment of renewable energy, decoupled from gas and CO2, will allow the recovery of competitiveness for industry.

In July, Spain lost 1.1 TWh of renewable energy due to grid restrictions. While solar PV and wind capacity continues to grow, energy markets expert and Managing Director of Our New Energy, Miguel Marroquín, stresses that storage is emerging as the key pathway to integrate surplus generation.

In July 2025, 11% of the renewable electricity generated in Spain could not be injected into the grid, compared with just 0.8% a year earlier. 93% of the restrictions came from the transmission network.

In August, seven projects totalling 646.665 MW were approved and four totalling 253.26 MW were rejected. The leaders were Iberdrola (180 MW), Zelestra (156 MW), and European Energy (26.16 MW), while Sungrow received approval for 55 MW of storage.

The updated document commissioned by aelėc indicates that the Spanish electricity system was operating on 28 April with only 60% of the usual margin to absorb reactive power. In Andalusia, the available capacity was just 7.5% of its potential.

Promotes the incorporation of storage in existing renewable energy production facilities. Facilitates the development of industrial projects by establishing the expiration of access and connection permits after five years. Accelerates the implementation of new demands, such as charging points, by setting response deadlines for distribution companies
