On 3 November 2026, following open bidding, JSC Ukrposhta signed a contract for the supply of electricity with Kyiv-based company LLC Enerho Zbut Trans. The total value of the contract was UAH 274.83 million, according to data from the public procurement system Prozorro.
Contract terms and price structure
Under the terms of the agreement, 32 million kilowatt-hours of electricity have been ordered for the following year. The price per unit of energy is set at UAH 8.59 per kilowatt-hour. This amount includes several components: a calculated wholesale price of UAH 6.20, a tariff for energy transmission services of UAH 0.93, a supplier margin of UAH 0.03, and value-added tax of UAH 1.43.
The calculated wholesale price is determined as the weighted average price on the Day-ahead Market (DAM) for the base period. To calculate the actual price of the commodity in future settlement periods, this base price is multiplied by a fluctuation coefficient, with the transmission tariff and supplier margin added. At the time of signing the contract, the fluctuation coefficient equals one. It is calculated using the formula: the weighted average price on the DAM for the relevant period divided by the weighted average price on the DAM for the base period. The supplier margin remains unchanged throughout the contract term, while the electricity transmission tariff is set by the National Commission for State Regulation of Energy and Public Services (NCRECPS).
Comparison with other market operations
A margin of UAH 0.03 is typical for similar contracts. However, there are cases where other buyers procure energy on terms significantly more favourable to suppliers.
For example, on 3 November, the same day Ukrposhta signed its contract, state enterprise SkhidGZK contracted energy with a supplier margin of UAH 0.34. High margins were also recorded in contracts with Chernihiv municipal enterprise Teplokomunenergo (UAH 0.30) and municipal enterprise Ternopil Elektrotrans (UAH 0.55).
Meanwhile, many other state and municipal enterprises are ordering energy for the next year at margins similar to those in Ukrposhta's tender. These include:
- Municipal enterprise Vinnytsia Transport Company — margin UAH 0.00;
- State enterprise Ukrainian Special Systems — margin UAH 0.02;
- Delta-Lotsman branch — margin UAH 0.03;
- JSC Zhytomyroblyenergo — margin UAH 0.04;
- Pervomaisk municipal enterprise Zhytlo — margin UAH 0.06;
- JSC Ukrtransnafta — margin UAH 0.10.
Competitors and the winner's owner
In Ukrposhta's tender, among the competitors offering a higher price were LLC Poltavaenergozbut, LLC Trade Energy Solution, and JSC Energy Company of Ukraine. The formal savings on budget funds amount to 0.4%.
Kyiv-based LLC Enerho Zbut Trans, headed by Oleksandr Sereda, is owned by LLC Zbut Energy Ltd. The director of the latter is Andrii Sheludyko. In turn, LLC Zbut Energy Ltd is owned by JSC Ukrzaliznytsia. Since 2019, contracts between the winner and buyers totalling UAH 39.51 billion have been published.
This is the first time since the start of the full-scale invasion that Ukrposhta has procured electricity specifically from Enerho Zbut Trans. The postal enterprise's previous award of a tender to this company took place in 2019.
