Spain’s €700 Million Plan to Boost Energy Storage and Renewable Power
Spain has launched an ambitious €700 million (around $796 million) program to increase its energy storage capacity. This plan will add 2.5 to 3.5 gigawatts (GW) of storage. It includes pumped hydro, thermal energy storage, and battery systems. The goal is to improve how Spain uses renewable energy and to make its electricity grid more reliable and flexible.
This article explains what the program involves, how energy storage benefits the grid and environment, the market opportunities it creates, and who will benefit from this major investment.
Inside Spain’s €700M Storage Surge
The European Commission approved a new support scheme. It targets large-scale energy storage projects in Spain. It focuses on technologies like standalone battery energy storage systems (BESS), pumped hydro energy storage (PHES), and thermal energy storage. The program supports hybrid projects, which combine storage with renewable energy, such as solar or wind farms.
Spain’s electricity grid already generates more than half of its power from renewable sources. Renewable energy, such as solar and wind, can be unpredictable. Sometimes, they produce too much electricity, and other times, not enough. Without storage, excess renewable energy often goes unused or wasted.

This program helps by storing surplus energy when production is high and releasing it when demand rises. This reduces waste and decreases reliance on fossil fuel power plants that fill in gaps when renewable output is low.
- The funding will cover up to 85% of eligible project costs, including civil works, storage systems, and auxiliary equipment.
The Ministry for Ecological Transition and the Demographic Challenge (MITECO) manages the program through the Institute for Energy Diversification and Saving (IDAE). Applicants have until mid-July 2025 to submit proposals. Almost half of the funds will go to Andalusia. Galicia and Castilla-La Mancha will also receive support for regional growth.
Strong and Steady: Why Storage Makes the Grid Smarter
Energy storage plays a key role in balancing electricity supply and demand. When the sun shines or the wind blows strongly, renewable sources can generate more electricity than the grid needs. Storage systems capture this excess energy, holding it until it’s needed—such as during cloudy periods or at night.
This capability makes the grid more stable and flexible. It helps stop blackouts by making sure power is ready, even when renewable energy changes. A stronger grid helps homes, businesses, and industries. It gives steady electricity and cuts down on interruptions.
In 2023, renewable energy sources made up nearly one-quarter of Spain’s final energy consumption, as seen below. Spain surpassed its 2020 target set by the Renewable Energy Directive, achieving a RES share that was 1.2 percentage points higher than the 20% goal.

Energy storage also reduces the need for fossil fuel power plants to operate as backup. This lowers greenhouse gas emissions and cuts fuel costs. Spain’s plan to add 2.5 to 3.5 GW of storage capacity will significantly improve the grid’s ability to integrate renewable energy sources.
The program requires projects to be completed within 36 months of receiving funding, with operations starting by the end of 2029. Subsidy amounts vary by technology, for example:
- €250 per kWh for battery energy storage systems (BESS)
- €300 per kWh for grid-forming BESS and thermal energy storage
- €1,500 per kW for new pumped hydro projects
- €1,000 per kW for existing pumped hydro projects

Expanding Energy Storage and Net Zero Goal
Spain’s 2030 net greenhouse gas reduction target is set at 32%, which represents an average annual reduction rate (CAGR) of -3.6%. If the country does not adopt more ambitious measures, it could fall short of its 2050 net-zero goal by about 100 million metric tons of CO₂ equivalent. This will be about 40% below the required reduction, as seen below.

Investing in energy storage helps Spain meet its climate goals. This includes achieving carbon neutrality by 2050. Storing renewable energy instead of wasting it helps the country rely less on fossil fuels. This also cuts down greenhouse gas emissions.
Pumped hydro, thermal storage, and battery systems are effective technologies. They help balance the fluctuations in renewable energy generation. This means cleaner electricity is available more consistently, reducing the need to burn coal, natural gas, or oil.
The program also boosts local economies. It creates jobs in construction, tech development, and operations. Expanding energy storage draws green businesses and sparks innovation. This boost further strengthens Spain’s clean energy sector.
By improving energy autonomy and security, the plan helps Spain reduce reliance on imported fuels. This enhances long-term economic stability while protecting the environment.
Market Opportunities in Energy Storage
Spain’s new support scheme positions the country as a leader in the growing global energy storage market. Analysts expect this market to grow by 21% each year until 2030, per Bloomberg data. This growth is fueled by more renewable energy use and global grid upgrades.

Europe’s energy storage market alone could reach €16.5 billion ($18.7 billion) by 2027. Spain’s plan to fund 80 to 120 projects will give it a strong share of this expanding sector.
The program supports hybrid projects. These projects mix storage with renewable generation. This boosts efficiency and cuts costs. Spain provides a stable environment for investors and developers. This is thanks to support from the European Union and helpful national policies.
Companies that focus on advanced battery tech, thermal storage, and pumped hydro are already interested. The government’s open call for applications allows these stakeholders to act quickly and secure funding.
Who Benefits from Spain’s Energy Storage Program?
The €700 million fund helps many groups. This includes local governments, private companies, and research institutions. This inclusive approach encourages teamwork across different sectors and regions. It spreads economic and environmental benefits all over Spain.
The program will create skilled jobs in construction, engineering, manufacturing, and technology. It will also drive innovation in energy storage technologies and grid management.
By reducing fossil fuel use and improving grid reliability, the plan helps protect the environment and public health. It also enhances Spain’s energy independence, reducing vulnerability to global fuel price fluctuations.
Spain is boosting its energy infrastructure with big storage solutions. This shows other countries how to increase their renewable energy use. With the right technology and funding in place, Spain is well-positioned to lead Europe’s clean energy transition.
