Energy storage systems

A well-designed and properly maintained Battery Energy Storage System (BESS) is a smart investment. The balance of Finland’s power system increasingly relies on industrial-scale BESS. Energy storage systems balance the grid, help industries manage peak loads, and provide backup power when electricity supply must remain uninterrupted.

During periods of overproduction, excess electricity is stored in batteries. When production falls short, the stored energy can be used to cover demand. We design, build and maintain BESS in Finland and the Baltic countries.

We are a reliable construction and maintenance partner for BESS

We specialise in the construction and maintenance of large, industrial-scale battery energy storage systems. We deliver and maintain BESS competitively and efficiently, tailored to each customer’s needs. Regular and expert maintenance ensures that the energy storage system operates optimally throughout its lifecycle – improving safety, extending service life and reducing overall costs.

Our services include:

•  Project and site management
• Procurement and delivery supervision, including main transformers and BESS equipment
• Infrastructure, civil and electrical engineering design and documentation
• Civil works, foundations and construction
• Equipment installation (mechanical and electrical)
• Testing and commissioning
• Construction of substations and power lines
• Maintenance: inspection visits and planned service work for substations and BESS
• Electrical operation management
• Fault repair readiness
• Control room services

We design, build, modernise and maintain the substations and power lines connected to energy storage systems, ensuring reliable and safe grid integration.

In addition, we build energy storage systems integrated with wind and solar farms – so-called hybrid parks – either as part of a new project or to complement existing renewable energy production. Our team has strong expertise in planning, executing and managing large-scale projects, and we tailor the scope of our services to each customer’s needs.

Our services ensure you get the most out of your BESS.
