The TSOs of Bulgaria, Greece, Moldova, Romania and Ukraine jointly propose a route monthly product for bundled firm capacity for the period from June to October 2025 that will facilitate the transportation of gas from Greece to Ukraine.
The bundled capacity product for natural gas transmission from Greece to Ukraine will be offered via the strategically positioned Trans-Balkan route through the following Interconnection Points: Kulata/Sidirokastron, Negru Voda 1/Kardam, Isaccea 1/Orlovka, Kaushany and Grebenyky.
The monthly capacity product for June 2025 amounting to 31 356 129 kWh/d will be offered on the Regional Booking Platform (RBP) on 29 May 2025. Due to the limited time until the auction, in case that significant amount of the offered capacity remains unbooked, the TSOs consider running another auction for the rest of the month at a time that will be jointly announced.
Subsequently, on the 4th Monday of each month, the capacity product auctions for the following calendar month are planned to be held. The Uniform Price Auction mechanism shall be implemented for the allocation of capacity.
By October 2025, Ukraine needs to inject about 5 billion cubic meters of natural gas into its UGS facilities in order to prepare for the winter season and guarantee the security of vulnerable consumers. This joint solidarity action of the TSOs aims to satisfy the urgent needs of Ukraine given the critical position the country has been put in. It will facilitate Ukraine in procuring part of the necessary quantities through various sources, including LNG from the USA and other reliable sources via the Trans-Balkan route, allowing diversification and enhancing security of supply.
In order to ensure that the offered product is going to be utilized correctly and for the purpose of supplies to Ukraine only, auction participants will not be allowed to access national Virtual Trading Points (VTPs) and national exit points in the countries along the route, except Ukraine. Taking account of these restrictions, the route product shall be offered at a reserve price equal to the sum of the reserve prices applicable for monthly capacity at the IPs for the respective month, discounted by 25% (46% for GTSOU). This will not only enhance the attractiveness of the route, but will also contribute to minimizing the negative effects of financial barriers and the challenges that Ukraine is facing.
The vision of the Operators entails the principles of transparency and fairness, contributing to Ukraine’s security and energy independence in line with European policies for competition, sustainability and solidarity.
The route product is expected to lead to an increase of the utilization rate of the TSOs’ infrastructure along the route. This, in turn, would result in increased revenues for the Operators that will be generated from the sale of the so far unused capacity and thus lead to a reduction of transportation tariffs to the benefit of users of the gas transmission systems of Greece, Bulgaria, Romania, Moldova and Ukraine.
