Background

The seven-unit, 1,373-MW coal-fired Nazarovskaya power station is owned by Nazarovskaya GRES-2 JSC which ultimately belongs to SUEK.

The plant’s seven units were brought online between 1961 and 1968.

Unit 7 was built already in 1968 with design capacity of 500MW, but could not achieve its projected capacity for 50 years. Over 2011-2013 the unit was rebuilt, achieving initial capacity of 415 MW, this was stepped up to 433MW and later to 498MW, thanks to auxiliary equipment and technical adjustments.

In November 2020, refurbishment of Units 1-6 was completed which increased their overall capacity by 65 MW.

The power plant produced 2,599 million kWh of electricity in 2021, in 2020 generation was 2,560 million kWh. In 2022, generation increased to 4,244 million kWh as a result of low hydrology of the Yenisei river coupled with growth in demand. The plant generated 5,411 million kWh in 2025.

In November 2023, a new generator to replace the old one at Unit 3 was installed. The capacity of the new generator is 165 MW. It was commissioned in April 2024. It was unclear whether the capacity of the plant would increase by 20MW as a result. One source implied that the capacity is the same as that of the old unit (145MW). System Operator's planning documents from 2023 and 2024 did not indicate capacity increases of the unit.

Incidents

In March 2022, one of the five pipes of the pulverizing plant collapsed at the station. Its replacement was scheduled to take place later in 2022. There were no injuries due to this incident.

In February 2023, a large fire erupted at Unit 5 where an oil tank in the engine room caught fire. Unit 5 was planned for repairs in summer 2023 but due to the fire the repairs started earlier. The fire took 3 hours to extinguish. It was also mentioned that Unit 6 was in cold reserve at that time. It appeared that there were no casualties in the fire incident.

Modernization, Repairs and Refurbishments

In 2025, the station's repair programme totalled approximately 2 billion rubles (~$22 million), during which 12 boilers, 7 turbines, and 4 generators were overhauled, 150 tonnes of heating surfaces were replaced, and the rotor of the turbine generator on Unit 2 was replaced. In November 2025, a 1964-vintage auxiliary transformer on Unit 2 was replaced with a new unit under the Renovatsiya investment programme. In 2026, SGK allocated over 3.1 billion rubles (~$34 million) to the station's repair and investment programme. In February 2026, Unit 5 was temporarily taken offline for planned overhaul, including partial replacement of heating surfaces and electrostatic precipitator repairs.

Environmental Issues and Upgrades

In October 2025, black snow was observed in the city of Nazarovo in Krasnoyarsk Krai. Environmental experts and local residents attributed the discolored precipitation to soot emissions from the Nazarovskaya coal-fired power station, prompting an official investigation.

From 2025 to 2032, it was planned to replace and overhaul environmental equipment at 10 boilers. As a result, all power units will be equipped with electrostatic precipitators with a solid particle removal efficiency of over 99%.

As of December 2025, environmental modernization was ongoing. The plant began installation of continuous emissions monitoring systems (CEMS) on its four main stacks as part of a federal air-quality program. The first system was planned to enter operation by late 2026, with work on the remaining stacks continuing through 2028. According to the operator, these activities were expected to reduce particulate emissions by about 47%.

In 2025, the station received a Comprehensive Environmental Permit (KER) from the Regional Office of Rosprirodnadzor, Russia's federal environmental supervision agency, along with an approved Programme for Improving Environmental Efficiency (PPEE), providing the legal basis for a large-scale modernisation of gas cleaning equipment. Design and survey works were completed in 2025. In summer 2026, replacement of wet scrubbers on Unit 7 was scheduled to begin, and in autumn 2026, construction works on modernisation of battery cyclone ash collectors on Unit 2 boilers were planned to commence, with equipment deliveries already arranged. The programme covered eight boilers across Units 1, 2, 3, 4, and 7, and was expected to reduce particulate emissions by 47.2%. Total investment in the gas cleaning modernisation programme would amount to approximately 3.3 billion rubles (~$37 million) through 2032. The governor of Krasnoyarsk Krai noted that the investments were being made on the company's own initiative, outside the federal Clean Air programme.
