3.3.3 Environment Protection

Environmental Policy

PAOPublic Joint-Stock Company Rosseti Ural, being one of the largest distribution grid companies of Russia, is interested in environment safety and compliance of its operations with environmental regulations. Company’s facilities (power lines, substations, production sites) have minor impacts on the environment. The Company’s operations include such environmental impacts, as waste generation, physical effect, air contamination (minimal emissions); the Company has no wastewater discharges to surface water bodies.

The PAOPublic Joint-Stock Company Rosseti Ural’s environment policy was adopted by the Board of Directors^[33]. The focus of the Environmental Policy is to preserve a benevolent environment for current and future generations.

As of 31.12.2025 PAOPublic Joint-Stock Company Rosseti Ural has 196 facilities with an adverse impact on the environment, incl. 123 III category facilities and 73 IV category facilities. PAOPublic Joint-Stock Company Rosseti Ural has a license for collection, transportation, processing, utilization, deactivation, dumping of hazard Class I-IV waste (in terms of transportation of hazard Class I-IV waste)^[34]. The Company has 10 extraction licenses and extracts groundwater at 11 wells.

In 2025, the Company arranged a set of trainings for the employees: 88 directors and specialists underwent training on environment protection and ecological security, 84 employees were trained to process hazard Class I-IV waste.

The increase in costs in 2025 compared to 2024 by 17% was attributable to the development of sanitary protection zone projects, the conduct of inventories of emissions of pollutants into the atmospheric air, the arrangement of sites and procurement of containers, and the installation of metering units. The 52.4% reduction in payments for negative environmental impact in 2025 was due to the transfer of industrial waste for utilization rather than disposal under newly concluded agreements, as well as the recalculation of planned and actual payments for negative environmental impact.

Atmospheric Air Protection

The primary sources of atmospheric air pollution and harmful physical impact are motor vehicles (garage, open parking, enclosed parking), mechanical processing areas, welding stations, and workshops. All sources of atmospheric air pollution have an insignificant negative environmental impact. In accordance with production environmental control programs, annual laboratory-instrumental surveys of stationary emission sources and monitoring of atmospheric air quality at the sanitary protection zone (SPZ) boundary are conducted, with research protocols prepared. In 2025, laboratory studies of atmospheric air quality and physical factor impacts at industrial sites were carried out under production environmental control. Measurement protocols were obtained. No exceedances of established emission standards were identified based on measurement results. Since the facility’s contribution to atmospheric pollution at the SPZ boundary and residential areas does not exceed permissible levels, no additional measures to reduce pollutant emissions are required. No noise exceedances were observed at the SPZ boundaries of production sites, rendering noise protection screens unnecessary. PAOPublic Joint-Stock Company Rosseti Ural is not a regulated organization, as greenhouse gas emissions amount to less than 50 thousand tons of carbon dioxide equivalent per year (2025 greenhouse gas emissions totaled 29.2 thousand tons). The total volume of pollutant emissions into the atmospheric air across PAOPublic Joint-Stock Company Rosseti Ural in 2025 decreased by 11.9% compared to 2024 levels due to the inventory of emission sources.

Energy consumption and energy-saving

The Company has the Energy-saving and Enhanced Energy Efficiency Program through 2028^[36]. The Program stipulates the list of target indicators based on the Federal Law^[37] and decrees of regional tariff regulators.

Positive dynamics were observed by year-end compared to the previous year across all resource categories, except for hot water consumption for economic needs. The reduction in electricity losses was primarily driven by the effects achieved through both targeted and ancillary measures of the program. The decrease in in-house load of substations, as well as electricity, thermal energy, and gas consumption for economic needs, was attributable to temperature factors. Changes in hot water consumption were predominantly influenced by modifications to the resource supply contract terms, as well as metering device malfunctions (metering devices have been installed, and identified deficiencies have been rectified). The reduction in gasoline and diesel fuel consumption resulted from vehicle maintenance downtime and a lower volume of emergency restoration works compared to the analogous prior-year period, accompanied by an overall decrease in requests for vehicle provision. The proportion of energy-saving lighting fixtures utilizing LEDlight emitting diodes reached 93.8%. The majority of targeted and ancillary measures under the Energy Saving Program were implemented. Additionally, unplanned measures to reduce electricity losses and resource consumption for economic needs were executed.

The actual aggregate effect from targeted measures under the Energy Saving Program amounted to 34.4 million kWhkilowatt-hour, 724.3 Gcal, 909.7 m³ of gas, and 38.2 thousand liters of motor fuel (support measure), equivalent in monetary terms to RUBruble 157.5 million. In aggregate execution of targeted Energy Saving Program measures (including support measures), the Loss Reduction Program, and other ancillary measures, the effect totaled 40,567.5 tfoe (RUBruble 1,411.8 million).
