Permskaya SDPP, Power Unit No. 4

Construction of 800 MW combined cycle power unit no. 4 at Permskaya SDPP

Customer — OJSC Inter RAO – Electric Power Plants

The project includes construction of an 800 MW combined cycle power unit at the site of Permskaya TPP. Commissioning of the fourth power unit of Permskaya SDPP will meet the growing demand for electricity supply in the energy-limited region of the Kama region. The project will secure energy supply required by large-scale chemical production plants, ferrous and non-ferrous metallurgy, timber processing and mining industry in the region. As a result, Permskaya SDPP will increase its total installed power capacity up to 3,200 MW to become one of the five largest thermal power stations in Russia.

Power Plant was launched in 2017.
