500 kV Preobrazhenskaya Substation of Main Power Systems of the Urals is Put in Operation

On July, 11, 2019, the 500 kV Preobrazhenskaya substation of Main Power Systems of the Urals was put in operation in Orenburg region.

Main power system of the Urals (MPS Urals) are a branch of Federal Grid Company of Unified Energy System operating in Ural and Volga federal districts.

The service area of the branch counts 7 federal subjects with a population of about 17 million people.

MPS Urals ensures fault free operation of over 16 thousand km of power lines and 106 substations with total installed transformer capacity of 41.9 GVA.
