So far in 2025, cleantech start-ups have raised €557 million, six times more than in 2024. However, the lack of capacity in the electricity grid and recent regulatory decisions are raising concerns about the future.

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.
