1. Includes motor fuel (petrol and/or diesel) in the Company's vehicles (owned or fully leased), which are used to move employees, transport fuel, materials, equipment, waste/by-products and other uses. The record relates to vehicles such as cars, buses, trucks and other types of vehicles on which fuel consumption is controlled by the Company. It also includes fuel used to transport power generation fuel to the islands by tankers, which are fully leased by PPC.
2. Includes fuel for the needs of buildings in and outside Attica.
3. Includes electricity for the needs of buildings in and outside Attica.

Calculation assumptions and constraints:

PPC's energy consumption is mainly related to electricity generation. Very small energy amounts (in relation to the consumption of energy for the electricity generation) are consumed for the Company's buildings operation (space heating/ cooling and electrical purposes), as well as for company vehicles (service and corporate vehicles).

Consumption figures can be broken down as follows:

• Fuel consumption in thermal plants. This consumption includes including consumption by the plants themselves and consumption for district heating.
• Electricity consumed by PPC hydroelectric power plants.
• Fuel consumption for company vehicles and for heating company buildings.
• The consumption of heating oil for the needs of buildings in the area of Attica, AES/ASP/TSP, LKDM and LKM (Lignitiki Megalopolis).
• PPC operates a fleet of 1,421 vehicles, including 1,067 vehicles with ordinary license plates and 151 only used within the boundaries of the company’s premises, as well as 203 vehicles with license plates issued with Prefectural authorization. Those vehicles travelled 3.098 million km.

The table calculates the self-consumption electricity energy of the Interconnected Transmission System and the Non-Interconnected Islands units. As self-consumption energy is considered the energy used by a power plant and is NOT DERIVED from its own production but is supplied by the System / Network. The consumption of the hived-down Units that belong to our subsidiaries LIGNITIIKI MELITIS S.A. & LIGNITIKI MEGALOPOLIS S.A. is also included.

A-E2 | Climate change risks and opportunities

Sustainable Development Report 2020

Unit 5.4.2 presents "The TCFD's climate-related risks and opportunities - Strategy", and the scenario analysis results, performed by PPC's Strategy Department.

Actions for mitigating climate change risks are presented in unit 6.1 "Environmental Protection and Combating Climate Change"  (pp 139-155).

 

SS-E4 | Water management

Regulatory Risks

The Group may incur significant costs for compliance with environmental legislation, which includes, inter alia, the proper and efficient management of water resources.

Compliance costs may have an adverse effect on business, results, financial position and cash flow. Water management issues require the adoption and implementation of preventive and corrective measures which may mean limiting or even terminating existing activities or projects.

Future laws or regulations may affect the Group's business decisions and strategy by requiring significant environmental investments or payment for water use in hydro and/or thermal power plants and could potentially have a significant negative impact on business, strategic and financial planning.

Natural Risks

E/E consumption is subject to seasonal fluctuations and is primarily affected by climate conditions. However, the huge penetration of RES in E/E production has led to significant changes in the coverage of the remaining load and has to be covered by thermal and hydroelectric power plants, both in terms of seasonality and in relation to the intra-day load curve. 

Currently, peak load demand occurs more frequently during the winter season. E / E production may also depend on climate conditions, such as droughts or heat waves, which may limit energy production due to specific flow requirements for downstream cooling facilities or due to speed and wind or sunshine direction for the production of E / E from renewable energy sources.

Weather conditions are beyond the Group's control and, therefore, no assurance can be given that its hydroelectric plants will be able to meet their expected production levels. If hydrological conditions result in drought or other conditions that adversely affect hydroelectric production, there could be a material adverse effect on the Group's results. Lastly, potential rise in sea levels will cause significant damage to coastal infrastructure which means that the uninterrupted supply of electricity to island and coastal areas is in doubt.

Reputation Risks

Due to the volume and complexity of processes requiring the use of water resources, failures in water management may occur in the future, causing a potential risk to the company's reputation for its responsible attitude towards its environmental impact. Violations of applicable environmental laws and regulations or non-compliance with licenses could result in shutdowns of production plants, fines or lawsuits or other sanctions causing negative publicity. 

Water Management at Hydroelectric Power Plants

Through hydroelectric projects, flood protection is achieved and water supply and irrigation needs of adjacent areas are served. In addition, the dams ensure a minimum continuous supply to the riverbed (ecological flows), even during periods of severe drought, thus contributing significantly to the protection and management of the country's water resources. The operation of the plants is planned in such a way as to meet the conditions of the ecological flows, the needs for water supply and irrigation, in cooperation with the relevant regions (annual / daily planning), as well as the energy needs of the system.

Water Management at Thermal Production Plants

In the areas of the thermal power plants, water is taken from various sources and for various uses, such as in the Cooling Towers of the power plants. In the direction of rational water management, PPC recycles and reuses significant quantities, resulting in the reduction of the total volume required to meet its needs.

Water Management at Lιgnite Mines

In the mining areas of PPC's mining activity, the pumped water (surface and groundwater) for the protection of the mines, which is not used to meet these needs, will be allocated to neighboring municipalities mainly to meet irrigation needs. The surplus quantities are redistributed to the surface receptors (Sulu stream, irrigation channels and Chimaditida-Petron stream at the Western Macedonia Lignite centre and Alfeios at the Lignitiki Megalopolis S.A.). This discharge of drainage water enhances in the Ptolemaida region the water balance of the respective areas, improving surface water quality and ensuring the balance of the ecosystem by maintaining the ecological flow in some cases (Sulu stream).

 

Optional Environment Indices (Ε)

SS-E1 | Emission Strategy

PPC's environmental policy includes actions to reduce carbon dioxide emissions (CO2) during the electricity generation process in order to tackle climate change, which is one of the United Nations 2030 Sustainable Development Goals.

In order to reduce CO2 emissions by Thermal Power Plants, and tackle climate change, PPC implemented actions and programs that include:

• Investments involving the replacement of old thermal power plants, with new plants of modern technology and high efficiency, as well as the improvement of the environmental behavior of existing plants.

• Further development of hydroelectric projects and renewable energy projects.

• Further inclusion of natural gas in the energy mix.

• Promotion of energy saving actions and rational use of electricity.

• Participation in research programs for the application of efficient lignite technologies.

These actions result in the reduction, over time, of the average CO2 emission factor of the PPC energy generation system.

Assumptions, hypotheses, constraints used for the calculation

Based on the data of the annual reports submitted by the obligated facilities to EWR in 2020

 

In 2020 PPC has 63 facilities that fall within the scope of the Electronic Waste Register (EWR). Respectively, Lignitiki Megalopolis has 5 facilities and Lignitiki Melitis has 3 facilities. The obligation of the environmentally licensed facilities to submit an annual waste report is fulfilled through EWR.

 

The materials derived from the combustion of lignite (ash, gypsum, etc.), are included in the total quantities of waste to be managed by the two lignite subsidiaries and constitute the major part of the quantities, which in the case of these installations are considered and declared as waste. For this reason, the disposal rates (disposal operations D) appear particularly high.
