[9] In June 2007, Enel bought 29.99% of the shares in the company, previously owned by RAO UES.
[12][13] In 2020, Enel signed a deal to expand renewable energy development in the Republic of Tatarstan in collaboration with the Ministry of Industry and Trade.
[16] The 2nd stage includes three high pressure boilers (140 standard atmospheres (14,000 kPa) abs) and three turbo-units with respective capacities of 100, 100 and 38 MW.
The 3rd stage features two two-boiler single-turbine units for supercritical parameters with capacities of 310 and 300 MW, and the 4th stage includes one two-boiler single-turbine unit for supercritical parameters with a capacity of 300 MW.
The power plant also has a gas turbine expansion station (GTES) with a capacity of 11.5 MW.
In 1960, a high powered district heating system providing an output of 1,150 Gcal of heat power and 2,000 tons of hot water per hour for the cities of Sverdlovsk, Verkhnyaya Pyshma, and Sredneuralsk was put into operation at SUGRES.
[citation needed] In 1982, SUGRES converted the first stage of the power plant from coal to natural gas, with oil as a backup fuel.
[18] Nevinnomysskaya GRES is one of the largest thermal power plants in the North Caucasus.
The water supply for the power equipment is drawn from the Great Stavropol Canal and the Kuban River.
The startup of a newly constructed 410.2 MW CCGT on 15 July 2011 resulted in a significant increase in the power plant's installed capacity.
[citation needed] In June 2017, Enel Russia won the tender for the construction of two windfarms, one in the Murmansk Region with an installed capacity of 201 MW and one near Azov in the Rostov region with a capacity of 90 MW.
On 19 September 2019 construction began on the 201 MW Kolskaya wind farm, the largest renewable project in the Arctic Circle.
