Overview
Spain pledged ambitious renewable energy targets for 2030. In the electricity sector, renewable sources will account for 81% of the total generation and the goal is set to 48% of renewables over total gross final energy consumption by 2030. Spain has also pledged to have 19 GW of self-consumption and 22.5 GW of storage and the reduction of foreign energy dependence from 73% in 2019 to 50% in 2030.
The country is comprised of three levels of governance: central, regional (Autonomous Communities) and local (municipalities). There are multiple support schemes for RES-E technologies in place and other areas focus on supportive measures in the energy transition domain. Many programmes are regulated at the National level, however, Autonomous Communities and Municipalities also administrate funds and specific support schemes, such as tax exemptions or subsidies to cover for example 50% of the total costs of PV installations (for self-consumption).
Support schemes for activities related to energy transition are mainly available under the framework of the Spanish Recovery, Transformation, and Resilience Plan (PRTR) and managed by The Ministry for Ecological Transition and the Demographic Challenge (MITECO) and the Institute for Diversification and Energy Savings (IDAE). The main themes where financial assistance is published are: energy efficiency, renewable energy, mobility, hydrogen, water management, biodiversity, circular economy and just transition and demographic challenge.
To facilitate the search for incentives, MITECO has created a search engine where a catalog of incentives for citizens and businesses (open and close calls) can be found using different filters such as the region, topic of action, costs covered, etc. The platform currently includes measures and grants provided related to NRRP and PERTEs (strategic sectoral government plans) and can be found at: PRTR grants calls.
Moreover, to cover all public grants, a National Inventory of subsidies and grants search engine was created, which allows users to National Inventory of subsidies and grants filter by several fields such as year of publication, area of application, field of action, region, funding instruments, specific calls for SMEs, etc. and covering national, regional, and local entities. Therefore, up to date links to application details, dates, topics, etc. can be succinctly gathered on this site: National System for the Publicity of Public Subsidies and Grants
Last of all, research and innovation policies covering a broad number of topics including energy transition-related are managed by the Ministry of Science and Innovation. The State Investigation Agency (AEI) is responsible for financing, evaluating, awarding, and monitoring scientific and technical research activities. The Center for Technological and Industrial Development (CDTI) promotes innovation and technological development in Spanish companies.
Summary of support system
-
Support schemes for activities related to energy transition are mainly managed by the Institute for Diversification and Energy Savings (IDAE) under the framework of the Spanish Recovery, Transformation, and Resilience Plan (PRTR). Specific lines available at the moment (Feb/25) for:
- Canary and Balearic Islands (circa 500 m Є) related to sustainable energy strategies open to June 2026. See link: Energy Balearic and Canary Island | Subsides
- Program (MOVES) renewed for the third call (1.550 mЄ) to finance part of the cost of acquiring electric vehicles and the installation of electric vehicle charging infrastructure, among others. Recently closed but, periodically open new calls. Refer to: IDAE support schemes
- Pilot energy community pilot projects, 5th and 6th call closed. This program aims to support financially the creation of Energy Communities. Recently closed but, periodically open new calls. Refer to See link: CE IMPLEMENTA
- BIOGAS Prefeasibility study program financial grants focus on biogas projects for thermal and/or electrical uses. See link: Biogas feasibility grants
- Subsidies for the promotion of collective self-consumption facilities with or without electric storage with renewable energy sources, thermal renewable energy facilities and actions for zero-emission mobility.
- Subsidy (Grants for investment in RE electricity and thermal projects) - Allocation of non-refundable grants for electricity projects using RES are regularly open under different schemes and Administration levels.
- Tenders / Auctions: Economic Regime for Renewable Energies as per RD 960/2000 and specific terms added in the different calls periodically open – Allocation of a sliding feed-in premium.
- Net-Metering & Net-Billing - Self-consumption projects with surplus subject to compensation can benefit from a simplified compensation mechanism.
- Tax regulation mechanisms (Allowance on the Real Estate Tax for solar energy systems) - 50 percent rebate of the full amount of the tax for properties where a solar energy system for thermal or electrical use has been installed.
- Tax regulation mechanisms (Allowance on the Tax on Constructions, Installations and Works) - Rebate of up to 95 percent in favour of constructions, installations or works in which systems for the thermal or electrical use of solar energy are incorporated used to be available, depending on Autonomous Community and Location.
- RES-E building obligation (Minimum generation quota from RES in non-residential buildings) – Buildings larger than 3,000 m2 shall install a RE generation system (between 30 kW and 100 kW).
