In 2026, the European energy storage market will continue to explode, with a year-on-year increase of 67% in new installed capacity from January to April. Spain leads Southern Europe with 2.1GW of new capacity. In this context, Grenergy recently signed a cooperation agreement with CATL to purchase 1.5GWh battery products for its two major energy storage projects in Spain, Oviedo and Escuderos. CATL will deliver 252 sets of TENER S energy storage battery compartments, using high-density lithium iron phosphate technology, specifically designed for large-scale energy storage scenarios.

Double project landing in Spain

108 sets of battery compartments (700MWh) are deployed in the Oviedo project, which is the flagship benchmark project of Greenbox platform under Grenergy. It is expected to be put into operation in the first half of 2027 and has signed a ten-year capacity leasing agreement with an investment grade international utility company. The remaining 144 sets (800MWh) will be deployed to the Escuderos project, with a planned 200MW photovoltaic and 680MWh energy storage system. The battery system will be launched in the second half of 2026 and put into operation in 2027. A 12 year capacity lease agreement has been signed, and the photovoltaic sector signed a 12 year power purchase agreement with Galp as early as 2020. Escuderos will continue the integrated development model of photovoltaic and energy storage from the previous Atacama Oasis project in Chile. Both parties have previously supplied 1.25GWh of energy storage batteries to Gabriela in the fourth phase of the project.

Grenergy CEO David Ruiz de Andr é s stated that following the implementation of multiple large-scale energy storage projects in Chile, he hopes to bring technology and experience to Europe, and through the integration of independent energy storage and photovoltaic energy storage projects, help create a safer, more flexible, and cleaner power system.

30GWh reserve in Europe

According to reports, Grenergy has accumulated over 30GWh of independent energy storage projects in key European markets, including 3GWh in Germany, 5.8GWh in Italy, 5GWh in Poland, 7GWh in Romania, 6GWh in Spain, and 4GWh in the UK. Keywords: energy storage, new energy

The average duration of energy storage in Europe has increased from 2.1 hours in 2024 to 2.8 hours, indicating a rapid release of long-term energy storage demand. In the market window of a 67% year-on-year increase in installed capacity, this batch of reserves will become the core ammunition for Grenergy to seize the European energy storage market.Editor/Cheng Liting
