Fluence Secures Contract for Trzebinia Battery Storage Project in Poland

Home » Energy » Battery Storage » Fluence Secures Contract for Trzebinia Battery Storage Project in Poland

Fluence has been awarded the contract to deliver the 133 MW Trzebinia Battery Energy Storage System (BESS) being developed by DRI in southern Poland. DRI is a subsidiary of Ukraine’s DTEK Group. Additionally, DRI acquired its 133 MW / 532 MWh battery storage project in Trzebinia, Poland, on 24 July, 2024 after buying 100% of the shares from Columbus Energy.

Trzebinia BESS Project Factsheet

Location: Trzebinia, southern Poland

Developer: DRI (subsidiary of DTEK Group)

Capacity: 133 MW / 532 MWh

Construction Start Date: Later in 2025

Commercial Operations Start Date: January 2027

Technology Partner: Fluence (Siemens/AES JV)

Technology Type: Modular grid-scale lithium-ion battery platform (6th gen)

National Grid Operator: Polskie Sieci Elektroenergetyczne (PSE)

Supply Contract: 17-year contract via Poland’s capacity market with Polish PSE to provide capacity starting from 2027

Project Importance: Strengthens Polish grid flexibility, supports coal transition, enhances EU energy security

Scope and Significance of DRI-Fluence Trzebinia BESS Project in Poland

The Trzebinia BESS by DRI and Fluence will provide critical flexibility services to PSE – Poland grid operator. Additionally, as one of the first large-scale storage projects in Poland, it will provide frequency regulation and reserve capacity. Once operational, it will also help store excess renewable generation for grid support during peak demand periods. This will come from the country’s growing solar and wind portfolio, like the recently announced 390 MW BC-Wind offshore wind farm being developed by Ocean Winds in the Polish Baltic Sea.

Trzebinia BESS is also a cornerstone project. This is in the sense that it complements both existing renewable projects and new buildouts planned under Poland’s 2030 energy strategy.

Furthermore, Poland has traditionally relied heavily on coal, but EU climate mandates and national commitments are pushing developers to invest in renewables. This announcement continues to highlight the country’s effort to incorporate large-scale storage into its national grid as it diversifies away from coal.

Fluence: Delivering DRI BESS Project in Trzebinia, Poland

Fluence, a U.S.-German joint venture between Siemens and AES, is a global leader in battery energy storage solutions. Its selection to deliver the Trzebinia BESS reflects its proven track record in delivering large-scale systems across Europe, the U.S., and Asia.

The Trzebinia project will leverage Fluence’s sixth-generation modular technology platform. According to the manufacturer, these are designed for scalability and grid reliability.

Aligning with EU Energy Transition Goals

Other than achieving Poland’s 62 GW installed renewable energy target by 2030,  projects like Trzebinia BESS continue to support the EU’s Fit-for-55 framework. They also help meet renewable penetration targets by stabilizing variable output from wind and solar projects.
