Sanxenxo BESS is equipped with Sungrows PowerTitan 2.0. With a total installed power of 5 MW and a storage capacity of 20 MWh, the facility sets new standards for flexibility, safety, and sustainability in grid management. This advanced solution provides up to four hours of autonomy, ensuring efficient and safe operation under all conditions.
Javier Blanco, Country Manager Spain & Portugal at Sungrow, "The Sanxenxo project is a significant step forward for Spain’s energy transition. By integrating our PowerTitan 2.0 technology, we are not only enhancing grid stability and operational flexibility, but also supporting local communities with reliable, sustainable energy."
Empowering the Grid and Local Communities
The Sanxenxo plant provides operational flexibility to participate in balancing and grid adjustment markets, contributing to Spain’s sustainability goals. It can absorb electricity from the grid during periods of low demand, store it, and return it to the system when needed. Under complex operating conditions, the project will supply energy to approximately 2,000 households per year.
The project is part of the national call for innovative storage solutions, supported by Spain’s Institute for Energy Diversification and Saving (IDAE) and funded by the EU’s Next Generation program.
Safe and Reliable: All-in-one BESS solution
The project demonstrates Sungrow’s commitment to energy optimization, cost reduction, and compliance with highest international standards in safety and reliability. The PowerTitan 2.0’s technology significantly reduces both capital expenditure (CAPEX) and operational expenditure (OPEX) costs.
The integrated AC block design, with pre-assembled battery modules and inverters (PCS), ensures seamless integration, significantly reducing installation time and commissioning. The project complies with the EU electricity market and participates in grid balancing, ancillary services, and wholesale energy trading, ensuring competitive benefits for stakeholders.
The used lithium iron phosphate (LFP) batteries are renowned for their high thermal stability, safety, and long operational life—key attributes for large-scale storage applications. The system now also features liquid-cooled string inverters, optimizing heat dissipation and performance even in demanding environments. This ensures maximum operational reliability and longevity.
Moreover, the facility integrates active fire detection and extinguishing systems, alongside a comprehensive Energy Management System (EMS) for intelligent energy flow management.
