DTEK and Fluence energise the largest energy storage portfolio in Ukraine with a total capacity of 200 MW

• Project construction and commissioning, split between six sites across Ukraine, was completed in under six months to ensure it is ready to operate during the upcoming winter season
• The project uses Fluence’s Gridstack™ solution and is designed to provide 400 MWh of dispatchable energy – enough to power 600,000 homes for two hours

AMSTERDAM, Sept. 11, 2025 (GLOBE NEWSWIRE) -- Fluence Energy B.V., a subsidiary of Fluence Energy, Inc. (NASDAQ: FLNC) (“Fluence”), a global market leader delivering intelligent energy storage systems, services, and asset optimization software, has energised Ukraine’s largest battery-based energy storage project with a total capacity of 200 MW together with DTEK Group, Ukraine’s largest private energy company.

The project includes six battery energy storage systems of varying capacities – from 20 to 50 MW each – connected to the Ukrainian power grid. Collectively, the systems have the capacity to store 400 MWh of electricity, enough to power 600,000 Ukrainian homes for two hours. The storage systems, leveraging Fluence’s innovative storage technology, are expected to enhance grid stability and resilience in Ukraine through advanced grid-forming capabilities.

The project’s construction was completed in only six months, significantly faster than the industry average for projects of such complexity. The speed of construction was primarily driven by the urgent need for the project to become operational ahead of the winter season. Due to the challenges of war and restricted access to Ukraine, this is the first project Fluence has commissioned fully remotely. In preparation for remote commissioning, 20 Ukrainian power engineers received advanced training on Fluence’s existing project sites in Germany and Finland. The intent of this training was to enable the engineers to install and commission the battery project without Fluence staff on site. This advanced training and remote commissioning model played a key role in expediting delivery.

"This is a historic step for the Ukrainian energy system and will shape its development for years to come. We have implemented it together with Fluence, a global leader in energy storage. In cooperation with our American partners, we are integrating the latest technologies to make Ukraine's energy system more reliable and sustainable," said DTEK CEO Maxim Timchenko.

“We are honoured to collaborate with DTEK on this landmark energy storage project. The exceptional determination and effectiveness demonstrated by DTEK in bringing this forward is truly inspiring. This achievement is a beacon of resilience and a symbol of what can be achieved through strong international cooperation. Even in these very challenging times, innovation and partnership can light the way toward greater energy security. Together, we are contributing to a stronger, more resilient, and decentralized energy system that will support Ukraine’s long-term stability,” said Fluence CEO Julian Nebreda.

The new systems are expected to increase the security of electricity supply and reduce the risk of outages and accidents, especially in the event of a breakdown in dispatchable generation, such as gas turbines. Fluence’s energy storage systems will contribute to the development of a clean and resilient energy system through increased system decentralisation and should enable Ukraine to store power generated from a wide range of energy sources.
