Merus Power has announced a significant contract with Neve to supply a large-scale battery energy storage system designed for some of the planet’s harshest environments. The deal, valued at approximately 13 million euros, marks a major step forward in expanding reliable renewable infrastructure for Arctic conditions.
The agreed facility, boasting a 30 MW power output and 80 MWh storage capacity, is engineered to operate in extreme cold, enduring temperatures as low as –50 °C, as well as heavy snow and ice. The bespoke energy storage solution is slated for delivery to Rovaniemi, Finland, by the end of 2026. Alongside equipment supply, Merus Power will provide comprehensive operations and maintenance services for the installation.
Merus Power’s system integrates advanced grid-forming technology, which not only stores energy but also supports grid inertia — a critical factor for stabilizing electrical networks, especially in regions with high renewable penetration. The technology reinforces the grid’s ability to balance supply and demand, helping ensure stable power delivery under fluctuating conditions.
This project builds on Merus Power’s growing track record in delivering cutting-edge battery energy storage solutions across Northern Europe. Just last year, the company completed the first grid-forming energy storage projects in the Nordic region at Valkeakoski and Lappeenranta, demonstrating its capability to deliver resilient energy assets under challenging conditions.
Neve Oy, a multi-sector municipal group owned by the city of Rovaniemi, is responsible for critical infrastructure services in northern Finland — including electricity and heat production, transmission networks, water services and fiber-optic connectivity. The new storage system is expected to play a pivotal role in enhancing the operational flexibility and reliability of the region’s energy system.
Merus Power’s Chief Executive Officer, Kari Tuomala, emphasized the company’s commitment to meeting demanding grid requirements with scalable and reliable solutions. The agreement further strengthens Merus Power’s position as a key supplier of advanced energy storage systems in both Nordic and international markets.
