Power transformer for battery energy storage system in Finland

Łódź, Poland, January 2024  ZREW produced and, in cooperation with its Finnish partner Eurolaite Oy, delivered a power transformer to supply the battery energy storage system (BESS). For ZREW, this was the first order to Finland.

Order details:

  • Transformer specification: 31.5 MVA (118/20 kV)
  • Place of installation: Lempäälä, Finland
  • Delivery date: December 2023

The delivered power transformer enables the energy transfer between local electrical grid and the BESS. ZREW managed to supply the transformer within a relatively short period of time – 10 months from the contract being awarded, as well as fulfilled all requirements and expectations during the entire project’s execution. The delivery to Finland is fully in line with company’s long-term strategy to develop new markets and support green energy generation.

“We would like to express our gratitude to all our business partners involved and supporting ZREW to properly and timely execute this project – starting from inquiry, tender and contract preparation, going through all milestones within the execution process and finally during the transportation as well as on-site installation and commissioning activities. Having this experience, ZREW is fully committed to further support Finish market, and we’re looking forward to new opportunities and projects there,” says Marcin Błaszczyk, Sales Director at ZREW.

ZREW has plenty of references in many countries for substations supporting wind, solar, and hydro generation, and now can add a new one from Finland for energy storage application.

The BESS supplier, including the substation, is Merus Power, and the end customer is Taaleri SolarWind III – fund-managed by Taaleri Energia. The transformer supply was part of the substation delivery by Elegrid Oy, who also erected the transformer.
