Ukraine’s largest private energy company, DTEK, has announced a €140 million collaboration with Fluence Energy, Inc. to deliver the country’s first large-scale battery-based energy storage portfolio. The project, featuring six energy storage sites with a total capacity of 200 MW and 400 MWh, aims to enhance grid stability, support renewable energy integration, and improve Ukraine’s energy independence.

The systems, expected to be operational by October 2025, will supply short-term power for 600,000 homes—approximately half the households in Kyiv. The initiative forms part of DTEK’s #FightforLight campaign, ensuring energy supply amidst the ongoing challenges of war.

Maxim Timchenko, CEO of DTEK, highlighted battery storage as pivotal in creating a decentralized, secure energy system. Julian Nebreda, CEO of Fluence, emphasized the project’s alignment with Fluence’s mission to deliver cutting-edge energy solutions globally.

The battery systems will provide rapid frequency and power balancing services, stabilizing the grid within milliseconds. Their advanced grid-forming capabilities position Ukraine among the leaders in energy innovation. The decentralized approach aims to prevent outages and accelerate recovery after disruptions.

Fluence was chosen for its extensive experience, including projects in Lithuania and Germany. Post-installation, Fluence will train DTEK teams to oversee operations, ensuring sustainable maintenance and paving the way for future collaboration.
