The fundamental principles of the Company are to prioritise environmental protection, create safe working conditions, preserve the life and health of employees, improve efficiency, and apply the best available innovative and digital technologies that ensure sustainable development and eliminate negative impacts on the surrounding ecosystem and human health.
Environmental protection management
The Company’s main objectives in the field of environmental protection and environmental protection management are pursued in accordance with the following documents:
- PJSC Rosseti’s Climate Change Policy, which establishes climate risks relevant to Rosseti Group, risk management mechanisms and climate change adaptation measures. The purpose of the Policy is to streamline approaches to climate change in the course of the Company’s activities.
- PJSC Rosseti’s Sustainable Development Policy, which sets out PJSC Rosseti’s sustainable development agenda, particularly in the areas of environmental protection and rational use of natural resources.
- Environmental PolicyApproved by the decision of the Company’s Board of Directors (Minutes No. 568/2024 dated 16 April 2024)., the principles of which include the priority of environmental safety of production activities, taking into account the needs and expectations of stakeholders, and the scope of an environmental management system. This policy also emphasises openness and accessibility to information about ongoing environmental activities, as well as the continuous improvement of main production processes.
The environmental policy implementation programme at PJSC Rosseti South
Environmental management at PJSC Rosseti South in 2025 involved:
- Analysis of compliance of the Company’s production activities with mandatory environmental requirements for 2024, with target process performance indicators set for 2025;
- Certification audit for compliance with the requirements of GOST R ISO 14001. In the auditor’s opinion, the organisation maintains its management system in line with the standard requirements and demonstrated the ability to systematically achieve agreed requirements for products or services within the scope of its policy and objectives.
Results of environmental protection efforts
GRI 303-5, 305-1, 306-3, 306-5
All production sites of PJSC Rosseti South that have a negative impact on the environment are registered with government agencies. A total of 221 facilities were registered, including 194 facilities of the III category, 27 facilities of the IV category.
Protection of atmospheric air
All facilities that have a negative impact on the environment have respective permits (an inventory of sources of emissions of pollutants into the atmosphere was made, standards for permissible air emissions were established).
The Company engaged accredited laboratories to control the volume of air emissions in 2025. The test results did not show any above-limit values.
Water conservation
In 2025, there were 17 licences for the right to use subsurface resources for groundwater extraction (operating wells):
- 4 licences in the Volgogradenergo branch;
- 3 licences in JSC Rosseti Kuban (from 1 December
2025 – Kubanenergo branch); - 10 licences in the Rostovenergo branch.
In order to protect and rationally use water resources under licence agreements, groundwater quality assessment was carried out in 2025 (observation of groundwater level and temperature, recording of water consumption, sampling for bacteriological and chemical analysis, determination of physical properties of water).
Protection and rational use of land
In order to protect and rationally use land, the Company organised regular control over separate accumulation of municipal and industrial waste (waste tyres, transformers, batteries, mercury-containing lamps, oils, metal waste, etc.), their timely transfer to specialised organisations for treatment and placement in specialised landfills. In 2025, 2,119 trichlorodiphenyl condensers, waste equipment containing extremely dangerous pollutants, were transferred to the Federal Environmental Operator. The Company’s obligations under the Stockholm Convention on Persistent Organic Pollutants were fully fulfilled.

Main environmental protection activities
GRI 2-27
Atmospheric air protection
- Laboratory and instrumental control of air emissions at sources under contracts with accredited laboratories. The control results did not show any above-limit values;
- Development of measures to reduce emissions of harmful (polluting) substances into the atmospheric air during periods of unfavourable meteorological conditions;
- Development of sanitary protection zone projects for production sites, measures on observation programme at the boundaries of sanitary protection zones;
- Monitoring of carbon monoxide content in vehicle exhaust gases and timely repair of motor vehicles;
- Improvement of operational activities and repair production technology (by the enterprise);
- Use of certified fuels.
Protection and rational use of water resources
Groundwater was monitored in accordance with programmes developed and registered with the state authorities of the constituent entities of the Russian Federation in the field of regulating subsoil use relations for the Volgogradenergo, Kubanenergo and Rostovenergo branches.
Rational waste management
At all production sites, waste is accumulated in places arranged in accordance with the requirements of environmental protection legislation and legislation on ensuring the sanitary and epidemiological well-being of the population, with a view to its further transfer to specialised organisations.
The following measures were implemented in 2025 to achieve the waste management objectives set out by the Environmental Policy:
- Timely removal of industrial and solid municipal waste by specialised organisations;
- Maintenance of records of waste generation and movement;
- Control over the separate accumulation of industrial waste by type of waste and municipal solid waste in places specially designed and equipped for the accumulation of waste of a certain type.
Ecosystem and biological diversity conservation
The Company took measures to ensure the required level of ornithological safety at power grid facilities and, consequently, the required level of power supply reliability, which is achieved through the use of various types of bird diverters.
In 2025, PJSC Rosseti South installed 21,255 bird diverters on 10 kV overhead transmission lines, including 397 units at the Astrakhanenergo branch, 970 units at the Volgogradenergo branch, 16,923 units at the Kalmenergo branch, 2,675 units at the Kubanenergo branch, 290 units at the Rostovenergo branch.
Compensatory measures involved releasing 2,174 juvenile Black Sea trout and 653 Russian sturgeon fingerlings into the natural environment, which were grown at a special fish hatchery.
Two noise barriers were installed during the construction of the Yekaterininskaya substation. The power facility is located in Krasnodar Territory within the city of Krasnodar. The design of the substation site includes a pre-fabricated sound barrier built around the transformers.
