Unipro PJSC
Annual Report for 2020

Environmental Responsibility

Environmental Policy and Strategy

Environmental protection is a strategically important component of Unipro’s activities. The Company considers the environmental protection as a prerequisite for doing business as a going concern.

Unipro’s activities related to environmental protection and sustainable nature management are carried out in accordance with the approved Environmental Policy, which is based on the provisions of the federal and regional laws of the Russian Federation, as well as of the applicable international documents ratified in the country in accordance with the established procedure and the policies of Uniper Group.

The objective of Unipro PJSC environmental policy is to define the framework for the Company’s business and its commitments in various environmental areas subject to the requirements of ISO 14001:2015. These are decisions regarding use of environmental protection technologies, mitigation of adverse environmental impact, management of environmental risks, and liaison with stakeholders, whether government authorities, non-governmental organizations, or even Unipro employees.

Refining of Unipro Environmental Policy

The Company’s environmental policy is reviewed and refined taking into account the changing circumstances, needs and internal affairs of the Company

The amendments of the current laws of the Russian Federation are considered a major driver of such adjustments. In particular, the amendments introduced by Federal Law No. 219-FZ of 21 July 2014, which change the environmental regulation system and, in general, approaches to limiting the adverse environmental impact. It is also a waste management reform (Federal Law No. 458-FZ of 29 December 2014), which involves gradual introduction of new approaches in these areas.

Another major driver is the change of ISO 14001:2015, namely its requirement to establish a clearer framework for goal-setting in the policy itself.

And the third major driver is the revision of the environmental policy of the principal shareholder of the company (Uniper Group) both in connection with establishment of a new company, and revision of E.ON policy which was used as the basis for the development of Uniper environmental policy, mainly in terms of water use and greenhouse gas emissions. These aspects were also taken into account as part of Unipro PJSC activities. This includes reduction of water consumption, waste water processing, protection of water resources, which are the basis for the technological processes of the Company

To promote the objectives set out in the environmental policy, Unipro has adopted an environmental strategy that is updated on an annual basis and provides for the planning and scheduling of environmental protection activities for the next three years.

The environmental strategy provides for the activities required for upgrading the power plants to the best available technologies (BAT) (i.e. activities associated with incorporation of large-scale environmental protection projects into the Company financial program) wherever applicable. Besides, the strategy contains certain clauses providing for transition to zero waste by minimizing waste generation and maximizing waste recycling. At the same time, one of the most relevant objectives is to develop a system of corporate carbon regulation: 2021 — elaboration of BAT Reference Document No. 48 on energy efficiency, 2022-2023 — implementation of measures and recording the carbon footprint reduction. It is planned to implement ISO 14080:2018 (Greenhouse Gas Management and Adaptation to Climate Changes).

Strategic Environmental Plan for 2021-2023
Environmental Impact Management Scheme in Unipro

Unipro PJSC has developed environmental efficiency improvement programs for each power plant. The most far-reaching of these programs are obviously the ones developed for Adverse Impact Class I facilities. The programs developed for the other branches are aimed at improving the indicators to the extent possible given the age of equipment and physical possibility of implementing any additional environmental protection technologies there.

The existing environmental impact management scheme is developed through implementation of ISO 14001:2015 in Unipro PJSC. The environmental issue is the primary element of the management system (activities having a positive or negative environmental impact). The environmental issues are prioritized according to their significance, based on the established criteria.

Currently, Unipro PJSC uses the following criteria for assessing the significance of environmental issues:

  1. Are there any violations of the legal requirements regulating the environmental issue (for emergency situations - was there any incident, accident)?
  2. Is this issue covered by BAT?
  3. Does the impact of this issue relate to Environmental Policy?
  4. Does the issue have an impact on individuals outside of the Company?
  5. Are there any significant costs associated with the issue?

There are two possible answers “yes/no” for each criterion. The significance of the environmental issue is determined as predominance of “yes/no” answers over the other answers. Depending on the number of “yes/no” answers for each of the criteria, environmental issues are rated by the scale:

  • if the number of “yes” answers is 3 or more, the issue is significant;
  • if the number of “yes” answers is less than 3, the issue is not significant;

For significant issues, programs are developed to improve environmental efficiency (for Adverse Impact Class I facilities) or action plans for environmental protection (Adverse Impact Class II facilities).

The updated version of ISO 14 001:2015 contributes to the formation of a risk-based approach to the environmental management system. The procedure for environmental risk management is developed based on the approaches adopted in ISO 31000 series. For details on environmental risk management see Risk Management section.

Environmental management system

The Environmental Management System of Unipro uses the PDCA management cycle logic (Plan-Do-Check-Act).

For each environmental issue, the applicable requirements are identified, which include the mandatory legal requirements regarding environmental protection, as well as the policies of the main shareholder, the expectations and sometimes non-documented requirements of stakeholders.

Mandatory requirements include the requirements set by regulatory legal acts that are related to business and other economic activities and the assessment of compliance with which is carried out under state control (supervision), municipal control, bringing to administrative responsibility, granting licenses and other permits, accreditation, product conformity assessment, other forms of assessment and expertise.

Further, the applicable requirements form the basis for assessing the compliance of the Company’s branches through level 1 internal audits (at the level of branches), level 2 audits (conducted by Headquarters representatives) and certification audits for compliance of the environmental management system with the requirements of ISO 14 001:2015, as well as environmental SWOT analysis.

Based on the identified deviations and risks, the environmental efficiency improvement programs (action plans for environmental protection) and environmental risk management programs with specific measures, assigned deadlines and responsible persons are developed.

All the said actions are integrated into PDCA cycle.

In late 2020, for purposes of validating its EMS certificate received in 2019, Unipro successfully passed its first EMS certification audit for compliance with the ISO 14001:2015 international standard, administered by the Russian Register Certification Association (accredited by international certification bodies, which are members of the International Accreditation Forum)

Unipro cooperates with the FSAU Research Institute Center for Environmental Industrial Policy and the BAT Bureau on working issues related to explanations and business games on the introduction of the best available technologies

Environmental Investments

The environmental expenditures depend on such factors as the need to comply with environmental regulations, to make repair and upgrade equipment, and on schedules for the implementation of issue-related events. These activities also include development of regulatory and permitting documents which depends on the legal term of the documents (in most cases it is 5 years).

In 2020 the total environmental investments were RUB 119,802.6 thous. More than half of the amount relates to financing of the construction of fish protection facilities at Yaivinskaya GRES and PP Surgutskaya-2; RUB 24,145,807 thous. — to reconstruction of the sewage treatment facilities in Sharypovo, RUB 4,855,624 thous. — to reclamation of two sludge dump basins at PP Surgutskaya-2, RUB 2,945,253 thous. — to activities under NOx emission reduction program at PP Surgutskaya-2. The current operating expenses were to RUB 14,835,549 thous. and are related to waste disposal services, instrumental industrial ecological control, development of supporting and permitting documentation.

Energy Consumption and Energy Efficiency

A steady decrease in the specific consumption of conventional fuel for electricity supply is due to an increase in the total generation by the most economical CCGT power units in the total production balance. Total generation of the CCGT power units broken by years: 2018 - 22.4 %, 2019 - 23.4 %, 2020 - 26.0 %.

Fuel consumption per production (supply) of thermal energy makes up only 2.7 % of the total fuel consumption of the Company’s power plants (97.3 % of fuel is spent on electricity production). Changes in the specific fuel consumption for heat supply are due to the difference in the operating modes of the equipment in the combined production cycle.

Unipro power plants take energy saving and energy efficiency improvement measures. The differences in absolute resource savings per years are due to the difference in the measures taken.

Unipro uses water facilities in compliance with the applicable laws of the Russian Federation. The Company timely receives water use and water body protection permits in the relative executive authorities. The water withdrawal from water bodies by Unipro branches does not have a significant impact on water sources. 303-2

In 2020 the water withdrawal volume was 389,751 thous. cub. m. Most water withdrawn is consumed for industrial needs

Water consumption, thous. cub. m303-5


Reduction of the gross emissions for all substances is mainly due to a decrease in electricity generation in 2020, as compared to 2019. In addition, nitrogen oxides emissions are reduced in PP Surgutskaya-2 branch following the initiation of the nitrogen oxides reduction program in 2019 to reach the technological indicators set by the best available technologies.

Regarding the climate policy, Unipro PJSC primarily ensures that greenhouse statements comply with the Russian laws and, starting from the reference period of 2018, verifies greenhouse statements through independent auditors in accordance with International Standard on Assurance Engagements (ISAE) 3410 “Assurance Engagements on Greenhouse Gas Statements” with a level of “reasonable assurance engagement” at the request of the main shareholder Uniper SE to confirm the reliability of environmental statements on greenhouse gases.

The Company prioritises minimisation of waste generation and maximum recycling as the key elements of waste management.

Most of the waste produced by the Company is non-hazardous wastes of classes IV and V. Ash and slag waste from burning of coal (hazard class IV) is disposed of in ash disposal areas at Company facilities based on a special license. The same procedure is used to dispose of ash and slag waste from burning of coal, which is referred to hazard class V (not subject to licensing).

The higher hazard category wastes were generated in significantly smaller volumes: I-III. Oil and petroleum product sludge in hazard class III is used as lubricants or transferred to specialised licensed providers for neutralisation (incineration).

Waste in hazard class II (sulphuric acid from batteries and sulphuric acid electrolyte sludge) is neutralised in special tanks based on a license.

Wastes in hazard class I (mainly waste containing mercury, including fluorescent lamps, mercury thermometers and other measuring equipment) is transferred to licensed providers for neutralisation (de-mercurisation).

More than 90 % of wastes is placed at its own waste disposal sites, about 7 % - in landfills, 2 % - extraction of valuable components (including energy), 1 % - combustion in bulk.

Conservation of Biodiversity

Being fully aware of its responsibility, Unipro strives not to produce any significant impact on biodiversity and protected natural areas. The Company’s production activities do not cause any reduction in the number of species, changes in habital areas, spread of invasive species, pests and pathogens. 304−2

The Company pays special attention to the conservation and restoration of the fish stocks of rivers. Unipro assesses the impact on aquatic biological resources of those water bodies that it plans to use in its activities. Following the assessment results, certain conservation and compensation measures are taken. In particular, fish protection devices (FPD) are designed, baby fish is released.

In 2020, lake stocking was carried out at Shaturskaya GRES. In October, the branch carried out another stocking operation on the Shatursky lakes: 929 species of silver carp were released into Lake Svyatoe. Shaturskaya GRES stocks the Shatura area lakes with baby fishes every year to restore the local ecosystem. According to the established rules, the fall is the best season to stock lakes with fish, because the survival rate is relatively high. The baby fishes have been delivered to their new habitat in a special vehicle equipped with containers with oxygen frames. The place was inspected before their release. There was a check whether the artificial environment matched the natural environment, the temperature conditions and noise wave level were recorded. Baby silver carps were released to the water body by means of a special release hose.

Within the reference period the fish protection facilities were completed at PP Surgutskaya-2; fullscale tests of the actual fish protection efficiency under the program agreed with Rosrybolovstvo were started. The technical solution involved the use of a combined FPD with bottom electrodes, pontoon sections and a baffle boom.

Also in 2020, the construction of fish protection facilities was completed at Yaivinskaya GRES. The technical solution was an air bubble curtain with a floating boom.

Two fish protection projects

once again demonstrate how multifaceted the production activities of Unipro PJSC branches are, and what various tasks the Company’s specialists have to solve together with design and construction organisations.

Protection of aquatic bioresources shall be provided both by ensuring the regulatory quality of water in water bodies used by the power plants, and by measures designed to protect against direct mechanical damage of aquatic inhabitants, especially baby fish. The designers carefully calculated and justified the guaranteed fish protection efficiency of the facilities at both branches, to ensure zeropass of fish into the water-intake structures, which it will no longer be able to leave due to high speeds and flow turbulence. This was a truly fascinating and interesting engineering challenge. Now Unipro faces an equally important stage of instrumental confirmation of its effectiveness
