Taranenko, a case worth 93 million hryvnias and an order from Poroshenko: how the businessman ended up at the center of a scandal
The owner and director of JSC Dnipro Switch Plant, Serhiy Taranenko, is named in a case about embezzlement of 93,2 million UAH during procurements for Ukrzaliznytsia. At the same time, law enforcement is investigating possible overpricing of railway equipment purchased by the Pivdennyi (Southern) port.
This was reported by Telegraf.
The director and owner of JSC "Dnipro Switch Plant", Serhiy Taranenko, a former official aide to Member of Parliament Yaroslav Dubnevych, became one of the accused in the case about embezzlement of 93,2 million UAH during Ukrzaliznytsia procurements. At one time his name appeared in a draft decree on awarding the Order of Prince Yaroslav the Wise, and now companies connected to him appear in the investigation of procurements by Pivdennyi port.
The order, which was explained as a technical glitch
Taranenko runs JSC "Dnipro Switch Plant" and is its owner. According to YouControl, he also owns 42,2% of LLC VKP "TAKO". This company supplied the state port with railway equipment manufactured by the plant.
In May 2019, the businessman's name appeared in a published document from then-president Petro Poroshenko about awarding the Order of Prince Yaroslav the Wise, fifth class. Later the presidential administration said that a draft decree containing errors was posted on the site due to a technical glitch, and Taranenko’s award was part of that draft.
How the scheme worked in Ukrzaliznytsia procurements
The Specialized Anti-Corruption Prosecutor's Office is appealing a decision by the HACC (High Anti-Corruption Court of Ukraine), which in May 2026 closed the case on procurements of turnout products for Ukrzaliznytsia in 2015–2017. The court closed it due to procedural issues regarding pre-trial investigation time limits and their extension.
According to NABU and SAP, Yaroslav Dubnevych organized supplies of equipment through intermediaries — KRT Corporation and LLC Argo — even though the railway could have purchased it directly from Dnipro Switch Plant. The investigation claims officials tailored tender conditions to a specific manufacturer, and companies simulated competition.
According to the Judicial Power of Ukraine portal, the next appellate hearing in case No. 991/878/22 is scheduled for 18 November 2026.
What investigators found in Pivdennyi port procurements
The investigation is checking possible price inflation for switch, rail, and joint products for the state enterprise Maritime Commercial Port Pivdennyi. This concerns procurements from 2024–2025, in which the winner was LLC VKP "TAKO".
In March, July, and September 2024 the port held three procurements with an expected total value of almost 21 million UAH excluding VAT. The sole participant was TAKO. Contracts were signed by port director Oleksandr Oliynyk and the company's general director Vyacheslav Satunovskyi.
According to the investigation, officials informed the supplier in advance of product requirements and financing volumes. Tender documentation was drafted for the plant's products, restricting competition. BEB detectives compared the prices with prices for this manufacturer's products supplied to Poltava GOK, DTEK and other enterprises. They recorded markups of 1,5–2 times. Damages for the three contracts were estimated at 4,9 million UAH.
In March 2025 the port announced a new procurement with an expected value of over 6 million UAH including VAT. Dnipro Switch Plant asked to split the procurement into lots in order to participate directly in the bidding. The port rejected the request, and TAKO again became the winner.
Investigators believe that Satunovskyi agreed with the leadership of LLC Budindustriya and LLC ZRS on fictitious commercial proposals with inflated prices. They were supposed to create the appearance of a market price for the equipment. According to the investigation, the price of this contract was inflated by 2 million UAH.
