The automated emissions monitoring system at Krasnoyarsk CHPP-3 successfully passed the control of Rosprirodnadzor

The automated emissions monitoring system at Krasnoyarsk CHPP-3 has successfully passed control. The corresponding act was signed by a special commission of Rosprirodnadzor.

According to the document, installation and commissioning of the equipment were carried out in full compliance with the established requirements. The environmental monitoring system has successfully passed all the necessary tests. The data recorded by emission control sensors are recognized as correct and objectively reflect information about the operation of the plant.

All Krasnoyarsk thermal power plants of the SGC are equipped with an automatic emission control system (AEC). The sensors are installed on station pipes at an altitude of 80 to 100 meters and in real time measure the concentrations of five marker substances for production: nitrogen oxide and dioxide, sulfur dioxide, carbon monoxide, particulate matter (dust), as well as pressure, flow, humidity and oxygen content in the exhaust gases. Information is continuously transmitted to the company’s website and to the Ministry of Ecology of the Krasnoyarsk Territory, ensuring openness of data.

In December 2025, Rosprirodnadzor specialists confirmed the quality of the monitoring systems at two other Krasnoyarsk stations – CHPP-1 and CHPP-2. The automated monitoring system is an important component of the federal project “Clean Air” of the national project “Ecological Well-Being”. It provides objective control and records a reduction in the burden on the environment due to the implementation of large-scale environmental modernization and production development.

SGK, being one of the main participants in the project since 2018, has carried out a large range of environmental measures. Among the company’s landmark projects is the launch of the second power unit at Krasnoyarsk CHPP-3 in December 2025 under the capacity supply agreement (CSA-2). In conjunction with the new equipment, there is a modern electric precipitator, as well as a cooling tower to reduce water intake from the Yenisei and a dry ash removal system.

At Krasnoyarsk CHPP-1, large-scale environmental modernization will be completed in 2026. Here, instead of three old and low chimneys (from 105 to 120 meters), a chimney 275 meters high was erected to increase the dispersion area of ​​emissions and reduce their ground concentration. Two boiler units have also been replaced, and two turbines are being installed. 13 out of 15 electrostatic precipitators have already been installed with a dust collection efficiency of more than 99%. By the end of this year, two more gas treatment plants will be commissioned. Once all electrostatic precipitators are operational, the plant's particulate emissions will be reduced by 80% and total emissions by 20%.

As part of the “New Heat” project, SGK is converting private sector houses to electric heating. In Krasnoyarsk, 640 households have already switched to modern and clean electric heating, which has reduced atmospheric emissions by 2 thousand tons per year. 37 inefficient boiler houses were closed, and consumers were transferred to power from thermal power plants equipped with modern electrostatic precipitators. The expected result of the implementation of the comprehensive environmental program of the SGK in 2026 is a reduction of emissions into the atmosphere by 8.7 thousand tons.
