One of Finland's most significant battery energy storage projects launches in Rovaniemi – Energy solution for Arctic conditions
In Rovaniemi, one of Finland’s largest battery energy storage systems (BESS) will be built for Neve Oy, designed to operate in demanding Arctic conditions. The capacity of the energy storage system to be built in Rovaniemi is 30 MW / 60 MWh. The tendering process for the facility supplier is currently underway. Contract award is expected in January 2026. The aim is to commission the energy storage facility in early 2027.
The project will ensure the reliable supply of energy, support green transition to a more sustainable energy system, and improve the reliability of the electricity grid in the Rovaniemi area. The storage solution will strengthen Neve’s ability to provide safe and responsible power electric services to the region.
“The share of renewable electricity production has grown significantly in recent years and still continues to grow. Because electricity production depends on weather conditions, it is challenging to predict production volumes accurately. A functional power system based on highly renewable energy sources requires power generation equipment capable of adjusting the grid frequency. Electricity storage facilities make it possible to quickly balance the relationship between consumption and production and support the regional power grid,” says Jukka Partanen, Production Director at Neve.
Power Grid Engineers PGE Oy is selected to provide owner’s engineering services for the project, leading the project and managing its commercial and technical interests. PGE’s scope includes tendering process for battery energy storage system as well as ensuring the quality and technical compliance during the project execution. Power Grid Engineers PGE Oy brings decades of experience in project management, power grid modeling, and analysis of demanding energy systems to the project.
“Electricity storage can be used to balance the capacity of the electricity grid when consumption and production fluctuate. When faults occur in the power grid, such as a sudden drop in electricity production, the electricity storage system immediately supports grid frequency, balances the production-to-consumption ratio, and thus acts as a reserve that can be quickly utilized. This improves the fault tolerance of the entire power grid,” explains Aki Leinonen, PGE’s battery energy storage expert on the project.
Insplan Oy is responsible for the preliminary electrical engineering of the project, the procurement of Rovaniemi’s new 110/10 kV substation and power cable, and acts as the project’s safety coordinator. Sweco is responsible for the structural engineering design, including civil works and other construction related to the project.
