Hitachi Energy has signed an agreement with Nordic Electro Power (NEPower) to provide advanced power conversion technology for Finland's largest battery energy storage system (BESS) in Haapajärvi. Switzerland-based energy company Alpiq is building the 125 MW / 250 MWh facility to support Fingrid's reserve market and help balance fluctuations in energy production and consumption.

The project represents a significant investment in Finland's energy infrastructure, with Hitachi Energy's technology designed to maximize system performance while reinforcing the stability of Finland's power grid. Construction of the Haapajärvi facility is currently underway, with commissioning planned for mid-2027.

Technology Components and Capabilities

Under the contract, Hitachi Energy will supply NEPower with several key components essential for the battery energy storage system's operation. The delivery includes a Power Conversion System (PCS), transformers, Ring Main Units (RMUs), a Power Plant Controller (PPC), and a SCADA-based energy management system.

The scope of work extends beyond equipment delivery to encompass comprehensive support services. Hitachi Energy will provide installation monitoring, commissioning, maintenance, and integration support for the project. These capabilities enable real-time monitoring and control, proactive decision-making, fault detection, and performance optimization, which enhances reliability for Alpiq.

The solution has been specifically designed as modular and scalable, engineered to withstand demanding Nordic conditions. The system offers fast load management capabilities, robust cybersecurity features, and grid-forming functionality, all of which support Finland's carbon neutrality targets while ensuring energy security.

Strategic Partnership and Market Context

Matti Vaattovaara, Managing Director of Hitachi Energy Finland, expressed satisfaction with the partnership, stating: “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.”

The project comes at a time when global energy storage capacity is expected to grow significantly. According to the International Energy Agency (IEA), global energy storage capacity is expected to grow sixfold by 2030. Additionally, commitments made at COP29 underscore the critical role of storage and grid infrastructure in building a sustainable energy system.

Company Experience and Market Position

Hitachi Energy brings substantial experience to the Haapajärvi project, having delivered more than 10 GW of energy-storage and renewable-integration solutions worldwide. The company's expertise is underpinned by over 30 years in the sector and includes more than 350 BESS references across utility, commercial, and industrial applications.

The company emphasizes that power conversion solutions are essential for unlocking the full potential of energy storage and safeguarding grid stability. High-performance power conversion solutions are identified as key enablers for large-scale projects like the Haapajärvi facility, which will serve as Finland's largest battery energy storage system once operational.

The facility's primary function will be to support Fingrid's reserve market operations while helping to balance fluctuations in energy production and consumption across Finland's electricity grid.
