Fluence, a market leader in energy storage technology, selected to supply the 55 MW / 110 MWh battery system supporting FinGrid with critical system services

DUBLIN and AMSTERDAM, April 30, 2025 (GLOBE NEWSWIRE) -- NTR, a leading sustainable infrastructure investor and asset manager, has signed contracts with all key equipment and contractor partners for its ready-to-build Uusnivala battery energy storage system (BESS) project located in Nivala, Northern Ostrobothnia province, Finland.

The 55MW / 110MWh BESS project will deliver system services including frequency regulation, grid balancing, grid forming and energy shifting.

Fluence Energy B.V., a subsidiary of Fluence Energy, Inc. (NASDAQ: FLNC) (“Fluence”), has been selected to provide their advanced battery technology solution, Gridstack Pro 5000, designed to effectively optimise land usage, enhance operations and reduce costs while providing industry-leading safety. Once deployed, the system will use Nispera, Fluence’s asset performance management platform, to ensure optimised performance.

Despro has been appointed as owners engineer and Nordic Electro Power “NEPower” has been appointed as balance of plant contractor, delivering both the BESS integration and 110kV substation works. Construction is anticipated to begin in the coming weeks with completion estimated by mid-2026.

Whilst NTR has a number of BESS projects under management, this project marks the first battery energy storage project of the L&G NTR Clean Power (Europe) Fund to go into construction, reaffirming its commitment to invest in and develop diversified clean energy infrastructure. The Fund is a joint partnership between NTR and Legal & General (L&G), a major global investor. At the beginning of April, the Fund reached its final close, securing total commitments of over €600m to drive Europe’s ambitious decarbonisation and energy security agenda.

The Uusnivala BESS is one of the larger BESS projects to be developed in Finland, with circa 250 MW currently installed across the market. This project is the Fund’s second development in Finland, having announced in October 2023 the acquisition of Pajuperänkangas 86.8MW windfarm which is now operational.

Liam Lyng, Associate Director, Construction at NTR, commented: “Uusnivala is a milestone project for us, being our first venture into the Finnish battery storage market. We are excited to partner with Fluence and local contractors to deliver a project that will contribute to Finland’s energy resilience and net zero ambitions.”

Hugo Smith, Managing Director, Benelux, Nordics, Baltics & France at Fluence commented: “We’re pleased to support NTR with the Uusnivala project — a BESS with grid-forming capabilities that reflects our shared commitment to accelerating the clean energy transition in Finland and enhance local system resiliency. This collaboration highlights the vital role of storage in enabling a more resilient and flexible power system.”
