The integration of a new gas reduction unit manufactured by ENERGAZ is nearing completion at the Verkhnetagilskaya GRES in Sverdlovsk Oblast. The modular unit has already been installed at the station, and specialists are currently conducting commissioning work before its operational launch.
The new equipment will become a key element of the station's power unit fuel supply system and is designed for a maximum capacity of up to 170 thousand Nm³/h. Its task is to stabilize and reduce the pressure of natural gas supplied to steam turbine boilers, ensuring stable and safe operation of power generation.
The gas is reduced from an inlet pressure range of 2–4.6 MPa to a design level of 1.2 MPa. The module includes three technological lines, two of which operate in normal mode, and one is provided as a backup. The throughput of each line is 85 thousand Nm³/h, which increases the reliability of the entire gas supply scheme.
The unit is additionally equipped with gas parameter control systems at the inlet and outlet, as well as measuring and analytical equipment that allows real-time monitoring of key fuel characteristics. The control is built on a two-level architecture: a local automated system is located directly in the technological compartment with a protective enclosure, and the operator's console is brought out to the power plant's control room.
Verkhnetagilskaya GRES, part of the Inter RAO – Electrogeneratsiya structure, remains one of the largest sources of electricity in the Middle Urals. The station's installed capacity exceeds 1 GW, and its annual output reaches approximately 5 billion kWh, making the facility one of the backbone enterprises in the region.
