Udmurtneft (part of Rosneft’s oil production complex) has commissioned a two-transformer Yelnikovo electric substation. The substation has a 35 kV voltage class and a total installed capacity of 32 MVA. It will ensure a reliable power supply for the existing and prospective oil production facilities of the Yelnikovskoye field.

During the reconstruction of the substation, more powerful transformers were installed and a system of online diagnostics of their technical condition was introduced. All equipment is of Russian manufacture and meets the latest energy efficiency and industrial safety requirements. The automated diagnostic system provides real-time control of the equipment, enabling prompt monitoring of operations and correction of any changes in processes.

The upgraded substation will provide power supply to the growing drilling volumes at the prospective Yelnikovskoye field and new production facilities being commissioned. Plans have been announced to construct 18 new wells in the area by the end of 2026 alone.

Earlier, Udmurtneft commissioned the newly built Kotovo electric substation, which has an installed capacity of 20 MVA, as well as a 110 kV double-circuit transmission line stretching over 30 kilometres. The 110 kV Sokolovka electrical substation has also been upgraded, increasing its installed capacity to 80 MVA.

Improvement of production asset efficiency is one of the key components of the Rosneft Strategy. The Company and its subsidiaries carry out systematic work aimed at rational use of resources, optimisation of electricity consumption, and distribution of electricity loads.

Following a nine-month energy saving programme in 2025, Udmurtneft succeeded in saving more than 24 million kWh of electricity. The economic gain is around 157 million roubles.
