Wedoany.com Report-Dec.16, Hitachi Energy has obtained a contract from Nordic Electro Power (NEPower) to supply advanced power conversion technology for Finland's largest battery energy storage system (BESS), currently under development by Switzerland-based energy firm Alpiq in Haapajärvi.

The project involves a 125MW facility designed to support Fingrid's reserve market and balance energy production and consumption fluctuations.

The facility features a capacity of 125 MW and is intended to participate in Fingrid's reserve market, helping to stabilize fluctuations between energy production and consumption. Commissioning is planned for mid-2027.

Hitachi Energy's solutions focus on enhancing overall system efficiency and contributing to the reliability of Finland's electricity grid. The delivery package encompasses power conversion systems, transformers, ring main units, a power plant controller, and an energy management system based on supervisory control and data acquisition technology.

The company will also oversee installation supervision, commissioning, maintenance activities, and integration assistance for the overall power setup. These elements provide operators with real-time monitoring, predictive analytics, rapid fault identification, and ongoing performance improvements, supporting dependable operations for Alpiq.

The power conversion design is modular and expandable, tailored specifically for challenging Nordic climate conditions. It incorporates rapid response capabilities for load management, robust cybersecurity measures, and grid-forming functions, aiding progress toward Finland's carbon neutrality targets and reinforcing energy supply stability.

"We are pleased to partner with NEPower on this landmark clean energy investment that strengthens Finland’s energy system. Energy storage, power electronics, automation, and electrification are essential for maintaining grid stability and flexibility as the energy transition accelerates," said Matti Vaattovaara, managing director of Hitachi Energy Finland.

Global projections from the International Energy Agency indicate that energy storage capacity worldwide could increase six times by 2030. Recent international commitments at COP29 highlight the critical role of storage systems and grid enhancements in developing sustainable electricity networks.

The Haapajärvi project exemplifies growing investment in flexible energy infrastructure to accommodate variable renewable sources while ensuring consistent supply. Battery storage facilities like this one enable better utilization of generated power, reduce waste, and respond quickly to demand changes.

Hitachi Energy's involvement draws on its expertise in high-voltage and digital solutions for modern grids. The collaboration with NEPower and Alpiq demonstrates coordinated efforts among industry participants to deliver large-scale projects efficiently.

In September 2025, Hitachi Energy revealed plans to allocate over one billion dollars toward expanding manufacturing facilities for electrical grid components in the United States, reflecting continued commitment to supporting energy infrastructure development across regions.

This Finnish initiative contributes to broader European goals for secure and sustainable power systems, integrating advanced technology to meet evolving operational needs.
