Estonian energy company is helping to construct a large battery park in Poland

  • 2025-07-18

The Estonian energy company Diotech is participating in the development of a large-scale battery park in Poland, with a capacity comparable to Estonia's largest battery park to date, located in Auvere.

The battery storage system, with a nameplate capacity of 56 MWh, will be built in the Nowe Czarnowo area. The project is led by Energix Polska, which is part of the Energix Renewables group operating in Poland, the United States, and Israel. Energix Renewables handles the entire life cycle of solar and wind energy projects, from planning to operation.

Diotech CEO Raivo Videvik explained that this battery storage park is the second large-scale project in the region, comparable to the Auvere battery park completed in April in cooperation with Eesti Energia. “Diotech's responsibility is to provide a full-service system integration, which includes system planning, validation of technical requirements, delivery of control logic and controllers, technology implementation, and ensuring the timely handover of the entire battery park. The necessary technology for the project will be supplied by SMA AG and LG Energy Solution,” Videvik said.

As this is also one of the first comprehensive large-scale energy storage solutions on the Polish market, Videvik believes the project could become a major springboard into Poland’s vast energy market.

Energix Polska currently has 300.6 MW of operational renewable energy projects, 40 MW under construction, and approximately 1 GW of solar, wind, and energy storage projects in development.

Founded in 2014, Diotech has grown into a corporate group with an annual turnover of around 25 million euros. In addition to the parent company Diotech OÜ, the group includes subsidiaries such as Diotech Electric OÜ, Diotech Nord OÜ, and Solar Wheel OÜ (Sunecor), along with subsidiaries in Latvia and Lithuania. Diotech specialists have built over 1,000 solar power plants and have upgraded more than 100 of them into controllable capacity using battery storage systems.
