Ukranian president promises accountability after anticorruption bureau announces probe into alleged Energoatom scheme.

Ukraine’s anticorruption agency has launched an investigation into an alleged $100m kickback scheme involving Energoatom, the state-run nuclear power company that supplies more than half of the country’s electricity.

The National Anti-Corruption Bureau of Ukraine (NABU), which operates independently of the government, announced the probe on Monday as the country faces another harsh winter under daily Russian bombardment.

In a statement posted on social media, NABU said that a “high-level criminal organisation” orchestrated the alleged scheme, led by a businessman and involving a former adviser to the energy minister, Energoatom’s head of security, and four other employees.

“In total, approximately 100 million USD passed through this so-called laundromat,” NABU said, without naming the suspects.

“The minister’s adviser and the director of security at Energoatom took control of all the company’s purchases and created conditions under which all contractors had to pay illegal benefits,” according to NABU chief detective Oleksandr Abakumov.

He said the group discussed increasing the kickback rate during work on protective structures at the Khmelnytskyi nuclear plant last October.

Investigators said Energoatom’s contractors were forced to pay bribes of 10 to 15 percent to avoid losing contracts or facing payment delays.

“A strategic enterprise with annual income exceeding 200 billion hryvnias [$4.7bn] was managed not by authorised officials but by individuals with no formal authority,” NABU said.

Zelenskyy calls for ‘criminal verdicts’

President Volodymyr Zelenskyy, addressing the nation on Monday evening, urged full cooperation with the investigation. “Everyone who has been involved in corruption schemes must receive a clear legal response. There must be criminal verdicts,” he said.

Zelenskyy’s comments come just months after he was forced to reverse plans to curb the agency’s independence following widespread protests. Eradicating corruption remains a crucial condition for Ukraine’s European Union membership bid, a goal Kyiv views as central to its post-war future.

Energoatom confirmed on social media that its offices were being searched and said it was cooperating with investigators.

Deputy Minister of Energy of Ukraine Svitlana Grynchuk told reporters she was not yet familiar with the case details, but promised a “transparent process” and accountability for anyone found guilty. “I hope that the transparency of the investigation will reassure our international partners,” she said.

Ukraine’s power infrastructure has suffered extensive damage from Russia’s air strikes this autumn, leaving large parts of the country without electricity. Although Moscow has not targeted nuclear reactors directly, Ukrainian authorities say substations linked to them have been repeatedly hit.

NABU released photographs showing stacks of cash, Ukrainian hryvnias, US dollars and euros, stuffed into bags and piled on tables. The agency did not disclose the owners of the seized money.

The agency conducted 70 searches, reviewed more than 1,000 hours of audio recordings, and deployed its entire detective staff over 15 months.

Opposition lawmaker Yaroslav Zheleznyak, a strong supporter of anticorruption reform, said he would introduce a parliamentary motion to dismiss Grynchuk and her predecessor, German Galushchenko, now serving as justice minister. Hrynchuk declined to comment on the proposal, while Galushchenko did not respond to requests for comment.

As Ukraine continues to battle both corruption and Russia’s war, Kyiv’s ability to convince its international partners of reform may prove as critical to its future as the fighting on the front lines.
