3.1.2 (i) Detailed descriptions of the points of the gas transmission system, names of the operators of the interconnected systems

​​“Transmission system operators shall publish at least the following information about their systems and services:

i) a detailed description of the gas system of the transmission system operator and its relevant points of interconnection as defined in paragraph 3.2. of this Annex as well as the names of the operators of the interconnected systems or facilities;”

Transmission system

County profile

The Company’s natural gas transmission network consists of “0” points, compressor stations, gas transmission nodes, measuring stations, high-pressure transmission pipelines and gas delivery stations directly supplying the regional natural gas distribution companies and industrial consumers.

The natural gas coming from imported gas sources, domestic productions and from underground gas storage facilities is injected into the Company’s transmission network at the entry points.

The natural gas received at the entry points is forwarded through the Company’s transmission network to the connected system operators and the direct industrial consumers. The transmission network is 5,874 km long and consists of steel pipes with a size between DN100 and DN1400, mostly with a design pressure of 63 bar (sometimes 75 bar).

In the compressor stations built into the transmission network are operating gas turbine-propelled centrifugal compressors, which have the function of increasing the system’s capacity by elevating the gas pressure so that the gas can be transported through the pipeline to the consumers.

The allocation of the natural gas transported through the pipeline system takes place at the gas delivery stations. These facilities continuously transport and transfer the gas to the connected system operators and the direct industrial consumers under monitored conditions.

The Company measures the amount of the natural gas and knows the quality of the natural gas at every input and output point of the transmission system. The quality of the delivered gas is measured with more than 600 measurement systems at the gas delivery stations, input points and international measurement stations for the gas suppliers, industrial and power plant consumers. We monitor the quality of the natural gas with continuously working gas chromatographs at the entry points, high capacity delivery and node points, where gases of different quality can mix.

There is a complex telemechanic remote supervision system (SCADA) on the natural gas transmission network supporting the execution of operation and system operation activities.

The Company operates a cathodic protection system covering its entire steel transmission pipeline network.
