Introduction

Natural gas is currently the most important energy source in Hungary: accounting for more than 40% of the country’s primary energy sources. Underground gas storage facilities play a crucial role in covering winter peak demand, along with establishing and maintaining the security of supply, since on a colder winter day, more than half of the country’s natural gas supply comes from gas storage sites.

Being the largest commercial natural gas storage company in Hungary, Hungarian Gas Storage Ltd operates four underground natural gas storage facilities, with a total working gas capacity of 4.43 billion m³ and daily withdrawal capacity of 51.78 million m³. In addition to ensuring the country’s long-term winter gas supply, it is a priority for the company to contribute to Hungary’s becoming a key player in the Central-European region.
