Exus Renewables is one of the first non utility companies to manage a Battery Energy Storage System in Spain. The 5MW BESS site is located in Galicia and is one of Spain’s first stand alone battery storage facilities. Sungrow, a leading Energy Storage System company, appointed Exus as energy asset manager for the site. The project is an important part of Spanish battery storage infrastructure. It is also an important platform for Exus to demonstrate its capability in third party energy asset management.
Exus Energy Asset Manager
Exus Renewables is a global energy solutions provider appointed by Sungrow to manage its stand alone 5MW BESS in Galicia. The project is part of Spain’s current 38MW of BESS capacity. The Sanxenxo site is made up of four battery containers with a total stored energy capacity of 20MWh. Exus Renewables owns and operates its own clean energy generation projects across Europe and South and North America. The partnership with Sungrow is a strategic platform for Exus Renewables to develop its third party BESS portfolio. It has also brought further investment in essential battery storage infrastructure for the renewable transition.
Alfonso Cebrián, Managing Director of Third-Party Energy Services at Exus Renewables, said: ‘We truly appreciate Sungrow’s trust in us to manage their Sanxenxo BESS site. This project is strategically important for our Third-Party Energy Services business and demonstrates how our expertise can create value across the entire energy generation value chain’.

BESS and the Renewable Transition
Spain’s Institute for Energy Diversification and Energy Saving (IDAE) invested in the project. This investment highlights Spain’s commitment to meeting the 2030 targets laid out in the National Energy and Climate Plan (NECP). Expanding the capacity of electricity networks is essential in the transition to renewables. Many renewable energy sources such as wind and solar do not have consistent output. As a result battery storage systems are key to flexible, balanced supply and improving the resilience and strength of the power grid. The 5MW project in Galicia is capable of providing the equivalent energy consumption of 2200 Spanish homes. It is investment in essential battery storage infrastructure during a significant turning point for energy networks.
Daniel Sánchez CEO of Sungrow Renewables Western Europe, said: ‘This facility is a strategic asset for our business in Spain, and we needed a partner with proven operational excellence and deep market expertise. We look forward to working closely with Exus to ensure the site delivers reliable flexibility and grid support as storage plays an increasingly important role in Spain’s power system.’
Essential Infrastructure
The 5MW BESS project is an example of Spain’s commitment to increasing BESS capacity. Sungrow appointed Exus Renewables as energy asset manager. Such partnerships help encourage investment and accelerate the growth of national BESS capacity. Battery storage infrastructure will provide essential flexibility and grid support in the transition to renewable energy sources. IDAE investment in the Sanxenxo site highlights Spain’s commitments to its 2030 NECP targets.
