Energy saving and energy efficiency enhancement

Measures aimed at energy saving and energy efficiency enhancement in JSC Tyumenenergo in 2014 were implemented in accordance with Russian legislation (Appendix 9.2) and JSC Tyumenenergo Program on energy saving and energy efficiency enhancement for the period of 2014–2018 (hereinafter — Program). The Program was approved by JSC Tyumenenergo Board resolution dated 27 December 2013 No.26/13.

In the course of energy management system implementation (hereinafter — EnMS), EnMS documentation required to conform to the ISO 50001: 2011 was developed. When performing primary energy analysis based on ISO 50001: 2011 and in accordance with JSC Tyumenenergo energy analysis technique, the following consumers requiring a considerable amount of fuel and energy resources were detected: processes, equipment types, variable factors and staff categories, exerting significant impact on energy consumption.

When implementing EnMS, training workshops for Company employees were held to cover the following subject areas: “Implementation of Energy management system in accordance with ISO 50001: 2011” and “Internal audit of Energy management system in accordance with ISO 50001: 2011”. The training familiarised participants with the requirements imposed by ISO 50001: 2011 on EnMS, its elements and EnMS documentation. Participants gained knowledge on how to plan and conduct EnMS audits, define and resolve non-conformances, carry out corrective and preventive actions by dealing with EnMS.

Internal audits of EnMS were conducted in Company.

Results of EnMS internal audit, in principle, confirm efficiency of EnMS implementation and its operation state maintenance including energy efficiency enhancement (energy performance).

In accordance with the Program the target values of energy saving and energy efficiency enhancement are the following:

  • Energy loss at transmission and distribution over electric mains;
  • Consumption of energy resources for economic needs;
  • Energy meters available on retail market in accordance with the Program on implementation of energy consumption metering system.

The program on JSC Tyumenenergo energy saving and energy efficiency enhancement consists of sections, target-oriented subprograms (activities) and relative measures. The last are divided into measures on reduction of losses at transmission and distribution of electrical energy over electric mains and measures on reduction of energy resource consumption for industrial and economic needs that are subdivided into administrative and technical measures.

Target-oriented measures include measures that provide reduction in energy resource (including electrical energy) and (or) water consumption at least by 15% of annual resource consumption, 80% — return on investment within 5 years for energy resource and (or) water consumption in the field of industrial and economic needs. Payback period for measures providing reduction of loss at transmission and distribution of electrical energy over electrical mains does not exceed 10 years.

Associated measures for optimization of industrial and economic costs and measures on reduction of electrical energy loss include measures that have positive energy efficiency and do not correspond to criterion characterizing target-oriented measures.

According to the results of 2014 effect, amounts to 18, 400.9 TOE and 108.7 mln RUB excluding VAT and for subprograms:
