DTEK and Fluence start up the largest battery system in Ukraine

The system will supply 600,000 homes for two hours in the middle of the winter season.
Proyecto BESS en Ucrania

Ukrainian energy company DTEK and the multinational Fluence have taken a key step in the transformation of the Ukrainian electricity system by initiating the commissioning of its portfolio of battery storage portfolio most ambitious battery storage portfolio to date.

BESS project in Ukraine strengthens the network

First of all, this project comprises six sites with a total installed capacity of 200 MW and 400 MWh of storage capacity. This will make it possible to supply 600,000 households in Ukraine for two hours, a significant figure in the current context of the country.

The commissioning phase then includes extensive testing, first battery discharge and final adjustments before commercial operations begin in October 2025. This date strategically coincides with the start of the heating season. heating seasoncritical period for grid stability.

In addition, the deployment incorporates 698 cubes Gridstack designed to provide essential services such as frequency backup, power support and grid balancing. These functions will be essential to avoid prolonged power outages and ensure continuous supply to the population and industries.

Technical training for local operators

Also, given the restrictions imposed by the war, this project sets a precedent, as it is the first that Fluence has commissioned completely remotely. To this end, a group of Ukrainian engineers received advanced training at similar facilities in Germany and Finland, enabling them to operate the systems autonomously and safely.

Finally, it should be noted that this development strengthens the Ukrainian energy infrastructure and also symbolizes the positive impact of international collaboration in a complex context. The collaboration between DTEK, Fluence and Ukrenergo consolidates a more resilient power grid. more resilient and flexible and flexible, ready to meet the challenges of a country under reconstruction.
