Introduction

Natural gas is now the most important energy source in Hungary. In meeting the winter peak demand, and in establishing and maintaining the security of gas supply, underground storage sites play a major role. On any colder winter day, most of the country’s gas supply comes from these facilities. Being the largest commercial natural gas storage company in Hungary, Hungarian Gas Storage Ltd operates, maintains and continuously develops four underground gas storage facilities, with a total gas storage capacity of 4.43 billion m3 and a total daily withdrawal capacity of 49.8 million m3. With these figures, Hungarian Gas Storage Ltd is the largest storage provider in Central and Eastern Europe.  It is a major objective for the company to operate with a high level of excellence to ensure smooth winter gas supply in Hungary.
