RPC marks next stage of BESS development in Finland

  • Renewable Power Capital has signed the main construction/supply contracts for the Kalanti 50MW BESS facility and has confirmed that the construction works will start in March 2025.
  • The site will provide a 2-hour storage solution to the Finnish electricity Market.

IMMEDIATE RELEASE – London 11 March 0800 GMT

Renewable Power Capital’s first BESS site is planned to be operating in summer 2026. Located in Uusikaupunki, Finland, the project will bring 50MW/100MWh of storage to the system. The timelines were confirmed alongside the announcement of key project partners that will see the delivery of the significant project to the Finnish energy system.

Batteries for the site will be supplied by Sungrow, who will install a 2-hour solution with their newest model PowerTitan 2.0 liquid-cooled technology, as part of a 15-year contract with RPC.

Balance of Plant services will be provided by Suvic Oy, encompassing civil works, substation construction and BESS equipment mechanical and electrical installation.

The project is one of the largest of its kind in Finland and adds storage to RPC’s growing renewables portfolio in the region, including over 170 MW of onshore wind in operation across three sites. The BESS will provide grid services including frequency response but can also participate in energy trading on wholesale power markets.

Sarwjit Sambhi, CEO of Renewable Power Capital, said: “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. This is why we’re so pleased to be able to partner with organisations we really trust and have fantastic relationships with.

“We look forward to working with Suvic Oy and Sungrow to deliver this vital infrastructure to the Finnish energy system.”
