The Spanish government has proposed a EUR17bn development plan for its electricity transmission network until 2030, which would suppose the “largest investment in electrical networks in the country’s history” (Spanish government press release, 16/09/2026). The proposed investment represents 30% increase above the originally proposed budget of EUR13.6bn and a 144% increase from the current budget for the country’s electricity grid. The increase answers to comments received after the plan had been submitted for a public hearing.
The investment is expected to cover the country's electrification needs in industry and housing and meet the objectives of its National Integrated Energy and Climate Plan 2023-2030. According to the Spanish vice president and minister for Ecological Transition and the Demographic Challenge, the updated plan aims to support renewable power generation and to promote electrification of ports, industries and the housing stock.
The plan is expected to provide maximum additional funds of EUR10.2bn in the field of distribution networks, while the transport networks managed by Red Eléctrica de España (REE) should receive additional funds of up to EUR7.7bn conditioned on the definitive Planning approved by the Government. Overall, more than 6,700 km of new lines should be built, and nearly 8,200 km of existing networks should be repowered.
Spain targets a 48% share of renewables in final energy consumption and a 32% reduction in GHG emissions in 2030 (Enerdata’s Global Energy Research).
