One of the main pillars of Hungary’s energy security is Magyar Földgáztáróló Zrt. (MFGT) has four underground gas storage facilities, of which the largest capacity is located in the southern part of Bács-Kiskun county, in Zsana near Kiskunhalas. The modernized storage facility, put into operation in 1996 and expanded several times since then, has a capacity of 2.2 billion cubic meters; this amount is more than two-thirds of the total annual residential natural gas consumption.
Siemens compressors have been used in the storage in Zana for the storage that typically takes place in the summer, i.e. for injecting the gas arriving via transmission lines into the storage layers. Their continuous and safe operation is ensured by cooling water, the temperature of which is normally below 40°C. If the temperature is higher than this, overheating of the individual cooled systems and their coolants will result in the shutdown of the equipment. Avoiding such outages has become more and more challenging in recent years due to the persistent ambient temperatures above 35°C.
In order to ensure business continuity, taking into account the changed temperature conditions, it became necessary to develop a system with a cooling performance that is capable of producing the appropriate cooling demand even in the hottest summer heat. The electricity supply of the new facility was made possible by expanding the existing Siemens low-voltage electricity distribution equipment with two fields, by replacing the protection member of an existing reserve field, and by installing new auxiliary branches. For the implementation, Siemens Zrt. provided the devices and components, as well as provided support during the planning process through its partner, Univill-Trade Kft., which carried out the investment.
In addition to the current development, in the gas storage in Zana, Siemens’ control technology solution is also involved in the input and output of the energy carrier.
