Current (operating) costs for environmental protection in 2020 amounted to 481,978 thousand rubles. (less by 7%). In connection with the sale and purchase transaction of Krasnoyarskaya GRES-2 branch of OGK-2 JSC, since 01.10.2020, the current costs of waste management of the facility has not been taken into account. The current costs of land reclamation have significantly decreased, since Novocherkasskaya GRES branch of OGK-2 JSC did not clear the supply canal corridor of the Don River.
During the reporting period, work was carried out for 236 million rubles, within the environmental safety improvement program, including:
- investment program – 26 million rubles,
- environmental protection measures – 130 million rubles;
including:
- monitoring costs – 24 million rubles;
- costs for the development of permits – 6 million rubles.
Payments for negative impact on the environment decreased by 12% vs. previous year indicators due to a decrease in the actual negative impact on the environment by the branches of OGK-2 JSC a result of their production activities.
The actual negative impact on the environment turned out to be lower than that of the previous year due to a decrease in electricity generation from 54,688 to 44,247 million kW*h (↓ by 19%), delivery of thermal energy from 6,647 to 5,844 thousand Gcal (↓ by 12%). In addition, a decrease in the negative impact is due to a change in the volume of fuel burned: a decrease in the amount of coal burnt from 7,442.3 to 5,151.3 thousand tons (↓ by 31%), the amount of gas burnt from 11,478.4 to 9,732.3 million m3 (↓ by 15%), and the amount of fuel oil from 17.8 to 14.4 thousand tons (↓ by 19%).
In connection with the construction of a new section of the M4 Don highway, excess methane emissions took place when gas was released into the atmospheric air as a result of work on the reconstruction of a part of the main gas pipeline branch of Novocherkasskaya GRES, branch of OGK-2 JSC. Thus, payment for excess emissions has increased.
Payment for excess discharge can be explained by the discharge of insufficiently treated wastewater at Kirishskaya GRES, branch of OGK-2 JSC (the neutralizing tanks only allow adjusting the pH of wastewater). In addition, according to cl. 5 of Article 16.3 of Federal Law No. 7-FZ dd. 10.01.2002 “On Environmental Protection”, since 2020, the coefficient to payment for limit-exceeding impact has increased by 4 times, therefore, payment for discharges in Kirishskaya GRES, branch of OGK-2 JSC, has increased significantly.
At Troitskaya GRES, branch of OGK-2 JSC, payment for limit-exceeding discharge was significantly reduced due to the transfer of household waste water treatment facilities, which, due to dilapidation, failed to provide sufficient treatment, from the village of Troitsk to the City Administration.
Payment for limit-exceeding waste disposal is due to the absence of approved waste disposal limits for Troitskaya GRES within two months in the reporting year.
Emissions of Pollutants
Gross pollutant emissions into the air decreased, in total, mainly due to a decrease in electricity generation, lower fuel consumption and a change in the balance of burned fuel: reduction in the amount of coal burned from 7,442.3 to 5,151.3 thousand tons (by 31%), the amount of gas burned from 11,478.4 to 9,732.3 million m3 (by 15%), and the amount of fuel oil from 17.8 to 14.4 thousand tons (by 19%).
In addition, the decrease in gross emissions is due to the final decommissioning of coal-fired generating equipment of Serovskaya GRES, branch of OGK-2 JSC.
Limit-exceeding methane emissions at Novocherkasskaya GRES, branch of OGK-2 JSC, is associated with the construction of a new section of the M4 Don highway.
In terms of greenhouse gas emissions in 2020, there is a decrease in the indicator from 34,730,442 to 27,799,178 tons of CO2-equivalent, which is due to a decrease in the generation of electrical and thermal energy, a decrease in the amount of fuel burned.

Waste generation
Waste generation decreased by 25.5% due to a 21% decrease in ash and slag waste generation (hereinafter – ASW) due to a reduction in solid fuel combustion.
The presence of waste at the beginning and end of the year at Troitskaya GRES is shown only at facilities located in the Russian Federation (the ash disposal area of the branch is located in the Republic of Kazakhstan, in the territory of the Russian Federation there is only an emergency tank where ash and slag waste can be temporarily placed).
In 2020, the amount of waste used at the enterprise has significantly decreased. In 2019, Novocherkasskaya GRES, branch of OGK-2 JSC, in accordance with the requirements of the approved WGDLB, disposed waste “soil formed during excavation, not contaminated with hazardous substances, sand waste not contaminated”, generated when clearing the corridor of the supply canal and used for filling dams. In 2020, these works were not carried out.
The increase in generation of oil sludge wastes is associated with the pumping of water-oil emulsion from the emergency oil tanks of KTC-1 and KTC-2, its treatment at the unit for treatment of oil contaminated wastewater and sludge formation at Surgutskaya GRES-1, branch of OGK-2 JSC.

Water Use
Total water intake and preparation in the Company decreased. This indicator directly depends on the generation of electricity. In 2020, there was a 19% decrease in electricity generation.
An increase in underground water consumption occurred in Ryazanskaya GRES, branch of OGK-2 JSC, due to the following reasons:
- cleaning the pipeline after repair (partial replacement of the pipeline) before commissioning;
- repair of shower rooms and restoration of the working capacity of shower heads;
- transfer of plumbing units from industrial water to artesian water.
In Surgutskaya GRES-1, branch of OGK-2 JSC, the water consumption for block air conditioners increased due to the early start and late end of the warm period in 2020 (April – October).
Water use and wastewater disposal in 2020 decreased by 22–23%. This indicator directly depends on the generation of electricity and water intake. In 2020, there was a decrease in electricity generation by 19%, as well as a decrease in water intake by 23%.
In addition, in connection with the sale and purchase transaction in relation to Krasnoyarskaya GRES-2, branch of OGK-2 JSC, since 01.10.2020, the environmental impact from the economic activities of this facility has not been taken into account.
In 2020, the disposal of contaminated wastewater to surface facilities was significantly reduced due to the transfer of dilapidated treatment facilities to the City Administration by Troitskaya GRES, branch of OGK-2 JSC, in accordance with a court decision.
