The plan, to be approved soon by the Council of Ministers, is considered a "strategic commitment to Spain's present and future" and a "major driver of transformation," according to Aagesen. The initiative aims to generate economic activity, attract investment, create quality jobs, and strengthen the industrial fabric, while also promoting territorial cohesion and prosperity.
Unlike previous plans, the new roadmap focuses on new electricity demand, multiplying by 23.5 the amount to be met by the transport grid, from 2 GW to 47 GW. This figure represents a 71% increase over the initial proposal, after analyzing 2,566 public comments received.
Of the 47 GW capacity, 55% (26 GW) will be handled by the transport grid and 45% (21 GW) by the distribution grid. The demands to be met include 14.9 GW for industry, 12.4 GW for renewable hydrogen, 9.3 GW for data centers, 6 GW for housing, 2.5 GW for transport, and 1.8 GW for ports.
To achieve this deployment, 6,706 km of new transport lines will be built and 8,164 km of existing ones will be reinforced, along with 193 substations. 301 distribution support positions, 270 for generation and storage, 162 for direct consumption, and 59 on railway axes and in ports will be enabled.
Demand for housing, which has seen a significant increase after public comments, will be allocated 6 GW, equivalent to one and a half times the electricity demand of the Community of Madrid. The total investment required for this plan amounts to 17.142 million euros, almost 150% more than the current plan.
This investment will be channeled through the regulatory framework revision approved in July, Royal Decree 640/2026, which enables an additional investment of 17.900 million in transport and distribution networks. Aagesen recalled that renewable energy, with 154 GW since 2018, has provided competitiveness and a "shield against the volatility of fossil fuel prices."
