The project, the first one in the country utilizing the PowerTitan 2.0, is set to begin construction this month and will mark a new phase of energy storage development in the region, strengthening grid stability and optimizing renewable energy integration. The ceremony of the agreement between RPC and Sungrow took place during the recent Energy Storage Summit 2025 that was held in London.
The PowerTitan 2.0 system, a fully liquid-cooled solution, is designed to enhance efficiency and extend battery lifespan by ensuring precise temperature control across all battery cells. By adopting intelligent liquid cooling technology, the system significantly improves thermal management, reducing operational risks while maximizing performance achieving 90% round-trip efficiency (RTE), enhancing charging/discharging efficiency and longevity.
Sungrow will supply 20 units of its 5 MWh energy storage system, housed in compact 20-foot containers, seamlessly integrating battery cells and Power Conversion Systems (PCS). Additionally, Sungrow will provide comprehensive Operations & Maintenance services under a 15-year contract with RPC, ensuring long-term reliability, efficiency, and optimal project performance.
“This project represents a major milestone for energy storage in Finland, and we are honored to partner with RPC to bring our latest liquid-cooled BESS technology to the market,” said Iker Labiano, Head of ESS at Sungrow Iberica.
Sarwjit Sambhi, CEO of Renewable Power Capital, commented,“Finland is such a significant market for us. The energy system is in real need of efficient and well-managed storage to make the most of its abundant wind resources. We look forward to working with Sungrow to deliver this vital infrastructure to the Finnish energy system.”
The Kalanti BESS will provide two-hour storage capacity, enabling it to deliver essential grid services, such as frequency response, and actively participate in wholesale energy trading. Sungrow’s cutting-edge technology will play a critical role in optimizing the site's efficiency, reducing maintenance costs, and ensuring seamless integration with Finland’s renewable energy infrastructure.
“Thanks to its C5 corrosion rating, the PowerTitan 2.0 supports installations in diverse and challenging environments,” said Iñigo Cayetano, Senior ESS Product Manager at Sungrow Iberica. “The system has been already successfully implemented in projects around the world, including Uzbekistan, Philippines and the UK to mention only a few of them. Efficient, robust and safe, PowerTitan 2.0 is at the same time a reliable and high performance solution.”
