RN-Vankor, part of Rosneft's oil and gas production complex, has commissioned a 110/35/10 kV Tagul substation with a capacity of 2х63 MVA. The facility will ensure reliable power supply to sites at the Tagulskoye field, which is part part of the Vankor cluster.

Power is supplied to Tagul from the 150 MW Polyarnaya gas turbine power station at the Vankor field. A 110 kV transmission line spanning more than 70 km has been built to connect the power station with the Tagul substation.

Construction of the substation was accelerated through the installation of prefabricated structures.  The building contains power transformers, enclosed switchgear for 35 kV and 10 kV, and is equipped with a control centre.

The domestic engineering solutions applied at the Tagul substation have been proven by the successful operation of the Vankor energy complex in Far North conditions. The switchgear design remains operational even if individual components fail, enhancing overall reliability of power supply to the field's oil production facilities.

Tagul is the eighth 110 kV substation at the Vankor cluster fields. Two further similar substations are in the final stages of installation. The total length of overhead power transmission lines already exceeds 1,900 km.  The largest substation, Vankor, with a capacity of 250 MVA, connects the Vankor energy district to the country's Unified Energy System.
