Spain Unveils 2025–2030 Transmission Draft as Regions Push to Accelerate Key Links

By routing new renewable capacity toward Madrid’s overloaded grid, the draft sets off regional bids to accelerate projects now slated after 2030.

Overview

  • In a plan now out for public consultation, the energy ministry details three alternatives to move large renewable flows from Andalucía and Castilla-La Mancha toward Madrid, with specific corridors, substation sites and line upgrades.
  • The Junta de Andalucía will file formal objections to bring forward a high‑voltage link for Northern Córdoba—Maguilla–Peñarroya–La Lancha—with new substations, which the draft places beyond 2030.
  • Castilla-La Mancha’s government, through consejera Mercedes Gómez, said it will submit objections to secure full inclusion of regional transport and distribution needs, noting the draft partially meets its requests.
  • The proposal cites Madrid’s grid loading at about 82% and warns that failure to integrate planned renewables by 2030 would force greater thermal generation and higher emissions.
  • Named projects include the Manzanares–ManchegaBelinchón axis, multiple new substations (Montalbanejo, Barataria, Albaceteña, Casas) and conductor upgrades on key routes, with submissions due by December 16.
