Reduction of the Impact on the Environment in 2016

Бурейский заповедник

RusHydro Group focuses its activities on the rational use of natural resources, prevention of negative impact and environmental conservation in a favorable condition for present and future generations.

RusHydro supports advanced environmental technologies and initiatives that increase environmental safety of production facilities and reduce anthropogenic load on the environment.

4.2.1. Protection of atmospheric air

There is regular monitoring of emissions of pollutants into the atmosphere at production facilities of RusHydro Group. In 2016, the amount of emissions did not exceed the threshold criteria.

PJSC RusHydro uses renewable energy sources while implementing its activities. In the operation of reservoirs, there are no significant carbon dioxide (CO2) emissions, thereby the greenhouse effect is not exacerbated.

COOPERATION FOR COMBATING THE CLIMATE CHANGE

At the end of 2015, PJSC RusHydro supported the initiative to combine efforts of the Russian business to reduce environmental impact and prevent climate changes by signing the Statement of Russian business in terms of negotiations and adoption of new climate agreement at the 21st Conference of UN Framework Convention on Climate Change.

This initiative was an additional step focused on adoption of a new climate agreement at the 21st Conference of UN FCCC.

Since 2015, PJSC RusHydro is a member of the «Russian Partnership for Climate Conservation». This partnership is a voluntary association of Russian companies that recognize the need to reduce the anthropogenic impact on the environment and to prevent the climate change.

The main goal of the partnership is to unite the efforts of business in the interests of transition to environmentally friendly technologies and to bring the Russian economy to a new level of responsibility.

Since 2016, PJSC RusHydro has been regularly participating in the events organized by the «Russian Partnership for Climate Conservation».

In 2016, PJSC RusHydro continued to report in terms of greenhouse gas emissions to CDP (Carbon Disclosure Project), in which the Company has been participating from 2015.

In 2016, the PJSC RusHydro established together with JSC EuroSibEnergo and the «Association of Russian Hydropower» a working group to develop methodological approaches to study the processes of global climate change in terms of greenhouse gas emissions from the surface of freshwater reservoirs of HPPs and to assess their absorbing capacity.

The main tasks of the working group are the analysis of domestic and international experience of assessment of the emissions values and absorbing capacity of the HPPs reservoirs and the development of the assessment for the planned, projected, operated HPPs and those under construction.

PERFORMANCE OF RAO ES OF THE EAST ON GREENHOUSE GAS EMISSIONS

Emissions of greenhouse gases are calculated in accordance with the Decree of the Ministry of Natural Resources of Russia No.300 of 30.06.2015 and using RD 153-34.0-02.318-2001 «Methodical guidelines for calculation of gross emissions of carbon dioxide into the atmosphere from TPP boilers and boiler houses» and inventory data of the Carbon Trust. The amounts of emissions of greenhouse gases are determined on the basis of the data from specific facility, taking into account the facility’s fuel balance.

In 2016, the volume of greenhouse gas emissions decreased by 5.8%.

ACTIVITIES TO REDUCE HAZARDOUS SUBSTANCES EMISSIONS

Holding takes measures to reduce the level of impact on atmospheric air.
In April 2016, the subsidiary structure of PJSC RusHydro JSC Sakhalinskaya SDPP-2 completed the concreting of the foundation of a 150-meter chimney. The height of the structure will reduce the impact on atmospheric air, as the flue gases will be completely dispersed in the atmosphere, due to electrofiltration and purification by 99.6%.

A significant effect on reducing emissions is provided by the gasification of the power plants of JSC FEGC. From 2007 to 2016, Nikolaevskaya CHPP, the Khabarovskaya CHPP-2, seven boilers of the Khabarovskaya CHPP-1, power-generating unit No.4 of the Khabarovskaya CHPP-3 switched to gas. Thus, the hazardous substances emissions into the atmosphere decreased by a factor of 3, the output of ash and slag wastes decreased by a factor of 4.

For the whole duration of power plants gasification project, emissions from the Khabarovsk CHPP-1 decreased by 14 thousand tons per year, the output of ash and slag was reduced from 263 to 85 thousand tons. Atmospheric emissions of the Khabarovskaya CHPP-2 decreased by a factor of 10. Emissions into the atmosphere from the Nikolaevskaya CHPP have decreased for 10 years by 122.8 thousand tons, and the output of ash and slag wastes decreased by 900 thousand tons.

The Vladivostokskaya CHPP-2 became the main object of reconstruction in Primorsky Krai. Over the past seven years of the project, the station has reduced emissions from 49.3 to four thousand tons per year. The output of slag decreased by a factor of 13: from 629 to 48 thousand tons. Three boiler houses of Vladivostokskaya CHPP-1, the boiler-houses «Severnaya» and «VtorayaRechka» switched to gas.

By the end of 2017, the boiler No.15 of the Khabarovskaya CHPP-1 will be switched to gas. The reconstruction allows reducing the emissions by 15%.

In 2014, the Program of Development of Renewable Sources was established for the period until 2016 with a prospective for up to 2020 in RAO ES of the East. As part of the Program implementation, the replacement of diesel power stations production is carried out in the isolated zones.

4.2.2. Water management and water protection activities

Starting from 2013, the Company publishes information on hydrologic situation at HPP of the RusHydro Group companies at the special portal.

The RusHydro Group is one of the primary water consumers in the system of water management complex of the Russian Federation, most of the Company’s activities are carried out at water bodies.

RusHydro Group operates water facilities in a strict compliance with the requirements of the legislation. The company receives timely permits for water use and protection of water bodies in the relevant executive authorities. Water intake from the water bodies by PJSC RusHydro does not impact significantly the water sources.

In 2016, the total amount of water extracted by RusHydro Group decreased by 0.97% and amounted to 756,261 thousand m3 (in 2015, the amount was 763,646 thousand m3).

In 2016, shore protection works and hydrotechnical repairs took place in RusHydro Group. A number of branches carried out works on:

  • Repair of anti-erosion hydraulic structures;
  • Repair of regulatory structures;
  • Regulation of clearing of dredging of water bodies;
  • Clearing of river beds, canals, etc..

IMPACT OF THE RAO ES OF THE EAST ON WATER BODIES

Subsidiaries of PJSC RAO ES of the East also use water bodies for the purpose of withdrawal of water and wastewater disposal. Most of Holding’s companies do not impact significantly the water sources as total amount of water taken by the affiliates is less than 5 % of the water body amount.

RAO ES of the East does not take water from water bodies classified as natural area of preferential protection. The sources providing water are not valuable from the point of view of biological diversity. An exception is water intake by JC Chukotenergo at water reservoir on Kazachka river in Anadyr – water intake amounts to 1,602.82 thousand m3 or 20.5% of the total amount of water body – 7.8 million m3.

An important project on reduction of the negative impact on water bodies is the construction of a chemical-biological treatment and sanification station for wastewater of the Khabarovskaya CHPP-2.

In 2016, the amount of repeatedly used water by RAO ES of the East increased by 7.1%

4.2.3. Waste management

Production and consumer wastes are generated during the operating activities of the RusHydro Group enterprises. Primarily, there are wastes of hazard class IV and V, they are generated during reconstruction, repair works and maintenance of the equipment at facilities. The RusHydro Group companies do not transport wastes by their own efforts. Generated wastes are transferred on a contractual basis to specialized organizations that have licenses to collect and handle the wastes.
