Spain has been facing significant challenges in the transition to renewable energy. Despite the obvious benefits of clean energy sources, the initial investment is often expensive and, until recently, taxes were added that made the outlook even more difficult.
To counteract these barriers, the European Commission (EC) has approved a public aid scheme in Spain, the aim of which is to encourage the installation of renewable energies through subsidies. These grants comply with EU regulations and contribute to meeting the objectives of sustainability and reducing greenhouse gas emissions.
This article takes a detailed look at renewable energy subsidies in Spain, including the characteristics of the available programs, the recipients, and the most important details on how to access these benefits. We will review the origin of these subsidies, the different incentive programs, and make key distinctions between subsidies aimed at residential, business, and public administrations. In addition, we will review the environmental objectives that are expected to be achieved with these subsidies.
Aid for renewable energy in Spain

The latest renewable energy auctions have highlighted the importance of competition in this sector. Companies have shown increasing interest in installing new renewable energy sources with the aim of reducing CO2 emissions. Thanks to these auctions and the active participation of companies, sustainability goals are on track to be achieved.
Through Spain's aid scheme, more than 40.000 beneficiaries have already received subsidies for the installation of renewable energy systems since 2014. The scheme offers a premium to power generation plants and manufacturers that produce electricity through renewable energy or cogeneration systems. In other words, producers receive compensation for costs not covered by sales on the market.
Competitive auctions and grants
Since 2016, aid has been aimed at companies participating in competitive auctions. Successfully awarded companies that achieve a price below the current market price are entitled to receive compensation. This allows them to cover costs without incurring losses and to obtain a reasonable profit margin.
Following a thorough review of the aid scheme, Brussels has confirmed that it complies with state aid rules. This ensures that there is no overcompensation and that public funds allocated to this aid are proportionate and do not harm competition in the European energy market.
Additional aid programs in Spain
In Spain, auctions are not the only indicator of success in the energy transition. Recently, several autonomous communities have launched specific aid programs to promote the adoption of renewable energy. These programs are largely financed by the European Regional Development Fund (ERDF) and the European Union's Recovery and Resilience Facility .
Some of the most notable programs are:
- El Renewable Energy Programme of Catalonia (PROENCAT), which aims to add 12GW of solar capacity by 2030.
- El PREE5000 Program, which provides aid of 20% to 50% for municipalities with less than 5000 inhabitants.
- Regional incentive programmes in communities such as Andalusia, the Basque Country and Galicia, where aid is granted for thermal and photovoltaic renewable energy for both the residential and business sectors.
Aid for self-consumption
Self-consumption has gained ground largely thanks to public subsidies and programs such as Royal Decree 477/2021 . This royal decree, approved in 2021, allows the installation of self-consumption systems in the residential and productive sectors, promoting renewable energies such as solar photovoltaic and wind power. It also allows the incorporation of storage systems to maximize energy use.
Thanks to this decree, the aid, which initially had a budget of 660 million euros, was extended to 1.320 billion euros in 2022. This reinforces the Spanish government's commitment to a more sustainable and accessible energy system.
Financing and costs covered
The aid scheme covers a variety of costs related to the installation and operation of renewable systems, from the purchase of equipment to installation services. In the case of thermal renewables, for example, technologies such as aerothermal, biomass, geothermal and solar thermal are financed.
Beneficiaries of the aid
The beneficiaries of this aid are broad and varied. The aid is aimed at individuals, businesses, and local entities interested in reducing their energy consumption and investing in renewable energy. This includes:
- Individuals and communities of owners seeking to install photovoltaic or thermal solar systems.
- Private companies wishing to incorporate renewable energy into their production processes.
- Local entities and public bodies that seek to promote energy sustainability in their municipalities.
New opportunities with the Recovery Plan
With the extension of the Next Generation EU program until 2026, opportunities to apply for grants are expected to continue growing. The additional funding will facilitate the installation of renewable energy systems nationwide, with the aim of electrifying energy demand and reducing emissions. Available support includes tax deductions, property tax breaks, and direct subsidies for solar installations.
The impact of these measures is already visible, with a notable growth in grant applications in 2024. The number is expected to continue to increase as the deadline for some grants approaches, set for December 2023 and July 2024.
As investments in renewable energy grow, Spain is positioning itself as one of the leading European countries in the sustainable energy transition.
