Energy efficiency

The energy efficiency of PJSC RusHydro's facilities is initially very high, since most of the electricity produced by the company is generated from renewable energy sources. Nevertheless, at the Company's facilities, there are additional opportunities to upgrade energy efficiency through the modernization of primary equipment and the implementation of innovative energy-saving technologies, the optimization of using water resources, and the reduction of power consumption for in-house needs.

In 2013, the Company continued to implement the 2010-2015 Program on energy conservation and upgrading energy efficiency. The Program was developed pursuant to Federal Law 261-FZ (23.11.2009) "On Energy Saving and Improving Energy Efficiency and on Amendments to Certain Legislative Acts of the Russian Federation".

Implementation of the 2013 Energy Efficiency Improvement Program

Energy Efficiency Improvementin the Company's branches and SDCs

Efforts to upgrade the capacity and efficiency of hydro-power units and to reduce electricity losses at power transformers brought the Company a 220.186 million kWh growth in long-term average output per annum.

Progress to date has been the result of synergies from the technical rehabilitation and modernization program (technological loss reduction by replacing turbines and units, upgrading the quality and volume of repairs and installing the latest energy-saving equipment and devices).

In particular, in 2013, the Company replaced hydro-turbines with higher efficiency ones at the Sayano-Shushenskaya HPP. Furthermore, hydro-power turbine units and hydro-turbines were replaced with more efficient equipment at the Zhigulevskaya HPP and the Volzhskaya HPP.

In 2013, the Company carried out energy audits at the Bureyskaya HPP, the Zeyskaya HPP, the Nizhegorodskaya HPP, the Novosibirskaya HPP, the Sayano-Shushenskaya HPP and the Mainskaya HPP, the Cascade of the Verkhnevolzhskiye HPPs and the Cascade of the Kubanskiye HPPs. Based on energy audit results, the Company developed measures aimed at improving the energy efficiency of facilities and also prepared energy performance certificates.

Energy saving in sales activity is achieved by reducing technical and commercial electricity losses and by upgrading energy accounting. Principal efforts include:
  • introducing new methods of forecast consumption;
  • introducing the latest metering systems.

Businesses that do not have heavy energy consumption (e.g., design and engineering companies) are predominantly switching from incandescent lamps to energy efficient ones. These companies are also introducing automated control systems to monitor lighting and heating, etc.

Energy audit services

The Company provides energy audit services and issues site energy performance certificates. The service is provided to the Group, as well as to external consumers. JSC NIIES, JSC Ryazan Energy Supply Company, JSC Chuvash Energy Supply Company and JSC Krasnoyarskenergosbyt are members of the self-regulatory organization for energy audits, which is entitled to carry out energy audits. In 2013, energy supply companies in total carried out 35 energy audits. The cost of the services was more than RUR 5 million.

Education in energy saving

In working with customers (subscribers), energy supply companies hold consultations:
  • on organizational, regulatory, technical, financial and economic issues related to energy saving in industry, housing and the utility sector and the public sector;
  • on carrying out energy audits of businesses and organizations to determine the fuel reserve and energy resource savings and producing energy performance certificates;
  • on energy services (legal aspects, types of energy service contracts);
  • on assistance in working with information databases on energy-saving equipment and technologies.

In the reporting year, the Company continued to develop its regional Energy Saving and Energy Efficiency Centers, which have been established by energy supply subsidiaries in Krasnoyarsk, Novocheboksarsk, Ryazan, the Republic of Bashkortostan and the Chuvash Republic.

The Company's regional Energy Saving and Energy Efficiency Centers continue to work on installing automated electric power fiscal metering systems for different consumer groups. In 2013, these measurement systems were installed at 2,447 electricity metering points, and were then integrated into automated measurement and information systems for electric power fiscal accounting for energy supply companies.

Within the framework of the International Energy Saving Day, celebrated on November 11, regional centers conducted educational activities and a photo contest on energy saving and energy efficiency for schoolchildren.

In addition, in 2013, PJSC RusHydro energy supply companies' personnel replaced electric incandescent bulbs with energy-saving ones in children's social institutions as part of regional charity events.
