EXECUTIVE SUMMARY

The U.S. International Development Finance Corporation has approved a loan for DTEK’s 200 MW / 400 MWh battery storage portfolio in Ukraine. The six-site project, operational since September 2025, uses Fluence GridStack technology to respond to grid disruptions in milliseconds and support electricity system stability.

  • Companies: DTEK, DFC and Fluence

  • Capacity: 200 MW / 400 MWh

  • Location: Six sites across central Ukraine

  • Financing: DFC loan approved; amount undisclosed

  • Technology: Fluence GridStack

DTEK, a Ukrainian energy company, has secured loan approval from the U.S. International Development Finance Corporation (DFC) for its 200 MW / 400 MWh battery energy storage project in Ukraine. The financing was approved by DFC’s Board of Directors, supporting an operational battery storage portfolio designed to strengthen the country’s electricity grid.

The approval represents one of DFC’s largest debt financing transactions for Ukraine and its largest for the energy sector since Russia’s full-scale invasion in 2022. According to DTEK, the decision demonstrates continued U.S. support for Ukraine’s energy sector and could encourage further foreign private investment in the country’s recovery.

The battery storage portfolio comprises six sites distributed across central Ukraine. The facilities are already operational and use American technology to support grid stability. The batteries can respond to grid disruptions in milliseconds, helping maintain electricity system stability amid ongoing attacks on Ukraine’s energy infrastructure.

DTEK deployed GridStack battery technology supplied by Fluence, a U.S.-headquartered energy storage technology provider. Construction of the battery storage portfolio was completed in six months, with all six sites entering operation in September 2025.

The financing approval therefore applies to an existing operational battery storage portfolio rather than a newly announced construction project. The source does not disclose the loan amount, financing terms or the individual capacities of the six facilities.

DTEK CEO Maxim Timchenko described DFC’s decision as a demonstration of confidence in Ukraine’s energy sector. He said the approval would allow DTEK to deploy further capital into its project pipeline, strengthening energy security and supporting Ukraine’s recovery.

Timchenko also highlighted the role of international investment in mobilising long-term capital for Ukraine’s energy infrastructure. He thanked DFC and the U.S. Government for their continued support of the company’s energy resilience initiatives.

DFC CEO Ben Black said the agency’s investments would support American exports and critical infrastructure across several international markets, including Ukraine. His remarks also referenced projects in Jordan, Central Asia and Africa.

The announcement connects U.S. development financing with an operational battery storage portfolio that uses American technology. The six facilities provide rapid-response capabilities intended to help Ukraine manage electricity grid disruptions.

The DFC approval establishes a financing milestone for DTEK’s existing 200 MW / 400 MWh storage portfolio. It also supports the company’s stated plans to direct additional capital towards projects intended to strengthen Ukraine’s energy security in the coming years.
