Gas system operation

The Czech gas system currently operates without serious fluctuations and with a high level of security. In terms of volume, the current capacity of border transfer stations is sufficient both for current demand and its anticipated development according to the individual case studies. New cross-border interconnections, particularly those with Austria and Poland, have the character of route diversification and their realization is not necessary for ensuring secure operation.

In terms of the network, the situation in supplying central and northern Moravia and Silesia is only conditionally good. These regions are located outside the transit system, and also, three gas storage facilities are located here (Lobodice, Štramberk and Třanovice), which are connected to the intrastate transmission system. Differences during years reflect situation on market (speculations of traders – waiting for lower price for natural gas) and consumption that is highly dependent on temperatures.

Growth of daily and also annual values of consumption will be caused mainly by higher use of natural gas for electricity generation and heat production in CHP. Higher gas consumption, and in particular, its utilization for electricity generation will require an adequate development of storage capacity: for the Conceptual case study the requirement is the highest; opposite to this, the case study EU – Energy Savings does not need any new storage capacity.

In all the proposed case studies, the gas system is operable at high level of reliability, in terms of actual state of storage capacity an operational reliability. If the Czech Republic will require high storage capacity, it will be needed to subsidy gas storage operation in the case of low rentability.

The designed development of domestic gas storages is not only possibility how to ensure flexibility and reserve for supplies. Foreign storage facilities can be taken into account (security standards require to storage gas anywhere in EU) or short-term trading (capacity must be reserved at borders). Both possibilities cause that the energy dependency on foreign countries is higher; mainly in situation when natural gas is widely used for electricity production or for CHP. Similarly, the same situation takes place in flexibility and ancillary services for source base of power system – in terms of gas infrastructure it is a significant threat in the unstable conditions for investments, that flexibility and reserves will not be accessible in the whole EU.

Number of days of operation without limiting gas consumption with gas imports decreased by 75%


Medium-term horizon

Outlook for gas system operation until 2030 can be summarized as follows:

  • operational configuration of the network will change due to new elements in it; in terms of transmission capacity utilization a growth is anticipated after commissioning of EUGAL; gas flows will flow in direction north-west to south-east of the Czech Republic in increasing number of cases,
  • in all the case studies, until 2030 there will be growth of maximum daily consumption volumes of natural gas (increase by 20% in the Conceptual case study, by 13% in the EU – Energy Savings and by 23% in the case study EU – Low-Emission Sources),
  • in the period until 2030 there will be no need of new storage capacity, except incremental capacity at Dambořice facility and connection of facility in Dolní Bojanovice to the Czech gas system.
  • ratio of storage capacity/gas consumption will not fall below 40% in any presented case study.

Long-term horizon

Outlook for gas system operation until 2050, in terms of securing daily balances of demand and supply, can be summarized as follows:

  • despite anticipated construction of new nuclear blocks, all the case studies counts on significant growth in electricity production and heat energy from natural gas; supposing actual configuration, it will not be possible to connect all these sources to the gas network, mainly in north and central Moravia and Silesia. Connection will be possible under condition of realization of new Moravia pipeline, or another solution (construction of new only partial parallel pipe to actual DN 700),
  • until 2040 in all the cases and case studies, there will be growth of daily values of consumption (by 32% for the Conceptual case study, by 4% in the EU – Energy Savings and by 23% in the case of EU – Low-Emission Sources),
  • until 2050 a slight decrease of daily values of consumption will occur in case studies EU – Energy Savings, and slight increase in cases of Conceptual and EU – Energy Savings case studies,
  • in case of EU – Energy Savings there will not be necessary to build new storage capacities; the case study EU – Low-Emission Sources anticipates fulfilment of SEP requirement with help of new 200 mcm capacity, and in the case of the Conceptual case study it is about 1.2 bcm of new capacity.
