Overview
- REE’s new capacity map indicates only one in four transmission nodes can still accept new large-demand connections.
- Granted permits now total 129 GW for wind and solar, 16 GW for storage, and 19 GW for new demand, with 11.8 GW of demand awarded since 2022 still not in service.
- If all permitted demand on the transmission grid were built, Spain’s electricity use would rise by about 25%, according to REE.
- Coordination with distributors remains incomplete: agreements cover 45% of transmission–distribution interfaces totaling 33.1 GW, while distributor maps show roughly 88% node saturation.
- The government rejects claims of a grid collapse and is enforcing five‑year expiry and a 10% upfront payment on access rights, with a near‑term package to set connection rules for power‑electronics‑based demand.
