Main aspects of energy saving policy implementation:

Development and implementation of measures, and achievement of energy saving and energy efficiency improvement targets as well
Development and improvement of regulatory and internal documents that address energy saving and energy efficiency improvement
Upgrade of the organisation and management of energy saving and energy efficiency improvement system based on the requirements of ISO 50001:2018, Energy Management Systems. Requirements with Guidance for Use (national standard GOST R ISO 50001‑2023)
Introduction of pilot projects to improve energy efficiency; implementation of organisational measures aimed at planning, organising and managing the development and introduction of new equipment and technologies
Implementation of measures under the Energy Efficient Substation national project

To reduce technological consumption (losses), PJSC Rosseti implements measures aimed at the following:

Optimising circuit parameters and operating conditions under operation and operational management of power grids
Reducing power consumption for substations’ demands
Constructing, renovating and developing power grids, as well as commissioning the energy‑saving equipment (so, loss reduction is concomitant)

For more details on the amount of energy resources utilised at the Rosseti Group in 2023, please see Appendix 1 .

Energy Management System

PJSC Rosseti and most of PJSC Rosseti’s subsidiaries have the Energy Management System (EnMS) in place, which contributes to:

Improvement of energy efficiency targets
Reduction in consumption of fuel and energy resources
Achievement of the planned value of electric power losses
Procurements with due regard to energy efficiency requirements

Subsidiaries have implemented and maintain key elements of EnMS: planning, risks, documentation, functions and interaction of divisions, internal audits, and analysis by the management.

For more details on energy consumption and energy management, please see the Report on Social Responsibility and Corporate Sustainability of the Rosseti Group for 2023.

In 2023, the transmission grid complex of PJSC Rosseti obtained certificates of compliance with the ISO 50001:2018 international standard and GOST R ISO 50001‑2023 national standard for three years.
