Spain prepares to auction 5.8 GW of grid access

The Spanish government will hold an auction to award 5.8 GW of grid access for renewables and energy storage at 17 nodes located across all regions of mainland Spain.

Spain’s ministry for ecological transition released the draft ministerial order with tendering rules and criteria on Friday, and invited the public to send comments until June 24.

The capacity at each of the nodes is provisional until Spanish grid operator Red Electrica de Espana (REE) releases its 2026 plan for the transmission network, the ministry said.

Projects that consider high degrees of self-consumption, energy storage, hybridisation of technologies or repowering, and can start operations sooner will gain more points come evaluation time. Environmental and socio-economic considerations will carry more weight in the scoring process, with these including creating more direct jobs, re-investing in communities, setting the project in depopulated areas, and leaving behind the least amount of environmental damage at the power plant site and at transmission lines, the ministry said.

Any leftover capacity that is not awarded in this round will be available in future auctions.
