Overview

• Spain’s energy ministry opened public consultation on a 2030 transmission plan worth about €13.6 billion, projecting 375 TWh demand, a 61.4 GW peak, integration of 159 GW of renewables and more than 22 GW of storage.
• The CNMC began processing time‑limited operational measures and amended operating procedures 3.1, 3.2, 7.2 and 7.4 after Red Eléctrica reported recent abrupt voltage variations that could jeopardize supply security.
• On October 1, Red Eléctrica ordered wind and solar plants to lengthen injection ramps from 2 to 15 minutes with eight days to comply, a change industry groups say will cut production revenues and restrict access to adjustment markets until voltage‑control participation is enabled around January 1, 2026.
• The draft plan triggers regional moves: Catalonia stands to gain roughly 5.4 GW to power desalination, port electrification, petrochemical decarbonisation, the Tres Xemeneies Media City and the proposed Móra la Nova AI project, while Madrid warns more than 70,000 planned homes could slip past 2030 though the ministry allows revisions during consultation.
• Territorial details include new and expanded substations and lines such as Piélagos (2027) and ‘Cantabria Central’ (2029) in Cantabria, reinforcements in Asturias’ central and western zones, and upgrades in Castilla‑La Mancha to support projects like Hydnum Steel and Saceruela’s Power‑to‑X, with roughly 65% of funds aimed at network reinforcement, new links and distribution support.
