An autonomous power supply complex has been commissioned at the Kharasavey field of Yamal to provide electricity to construction sites

10 December 2021

As part of the project for arrangement of the Kharasavey field of PJSC Gazprom, a power supply complex has been created here to provide electricity to construction sites. The operating company and the owner of the power supply complex is Allocation Hub LLC.

The primary source of electric power is packaged gas-reciprocating power plants ROLT. These GRPPs are made based on the engines of MWM TCG 2020 series (Caterpillar) with a unit capacity of 2.0 and 1.2 MW. The main consumer is a rotational camp for 5,000 people.

Gas-reciprocating engines TCG 2020 V20 (2 MW) and TCG 2020 V12 (1.2 MW) have the best electrical efficiency in their capacity class - about 43%. GREs are characterized by high reliability, low operating costs, as well as are different by extended repair intervals and ease of maintenance.

The generating facility will also use mobile automated gas-turbine power plants PAES-2500 with a capacity of 2.5 MW each. These PAESs are designed to supply electricity to hydraulic flushing units.

The fuel for power supply complex is natural gas produced at the field. Its design parameters on purity, humidity, temperature, pressure and flow are ensured by the ENERGAS fuel gas treatment facility (FGTF). The maximum capacity of the facility is 8,000 m3 / h, including: consumption for GRPP – 5,000 m3 / h, for PAES turbines – 3,000 m3 / h.

FGTF is a multifunctional complex of two modules operating in cascade scheme. Process module No. 1 is intended for preliminary separation, filtration and pressure reduction of the incoming gas. Then the fuel enters to module No. 2, where the its final purification, flow measurement, heating and additional pressure reduction take place.


The Kharasavey gas condensate field is located in the Yamal-Nenets Autonomous Area, mainly on the Yamal Peninsula and partially in the Kara Sea. By the size of gas reserves (2 trillion cubic meters), it belongs to the unique category.

In March 2019, Gazprom began full-scale development of the Cenomanian-Aptian deposits here. The start of production is scheduled for 2023. In the future, it is planned to develop deeper Neocom-Jurassic deposits. The field is being equipped by JSC Gazstroyprom, the sole contractor of Gazprom Group enterprises.
