As part of Ukraine’s plan to become an international gas hub, Ukrtransgaz has announced a tender to modernize the nation’s largest underground gas storage facility. Located about 75 km east of Poland, the Bilche-Volitsa caverns can hold 17 billion cubic meters of gas, the equivalent of half of Ukraine’s annual gas consumption. In the tender, expected to cost $35 million, Ukrtransgaz seeks modern gas turbine engines for the compressor station at the reservoir. Overall, Ukraine can store 31 billion cubic meters.
