Energy consumption and energy saving

The Company has the Energy Saving and Energy Efficiency Improvement Programme for PJSC Rosseti South for the period 2022–2026Approved by the decision of the Board of Directors of PJSC Rosseti South on 13 May 2022 (Minutes No. 480/2022 dated 13 May 2022)..

Target indicators of the Programme:

• Reduction of electricity losses in transmission and distribution
• Consumption of energy resources for housekeeping needs
• Number of LED-based lighting devices

The actual electric losses for 2025 amounted to 2,929 million kWh, or 9.74%, compared with the planned value of 2,634 million kWh, or 9.36%, in accordance with the business plan for 2025, due to the inclusion of indicators for the Company’s Kubanenergo branch in December 2025 and exceeding the level of losses by this branch.

Reasons for non-fulfilment of the indicator related to motor fuel consumption by motor vehicles and special-purpose machinery:

• An increase in fuel consumption by motor vehicles and -purpose machinery on detached duty;
• Untimely renewal of the Company’s fleet of motor vehicles by derecognising obsolescent, inefficient vehicles and purchasing cutting-edge, cost-effective, multifunctional special vehicles (cranes, lifting trucks, drilling rigs and delivery vehicles). These new vehicles allow for a number of technological processes to be carried out by one vehicle, thereby reducing the consumption of motor fuel. These purchases are not included in the Company’s investment programme.
