Overview of Repower Group employees in full-time equivalents (FTEs)

Greenhouse gas emissions

The calculation of greenhouse gas emissions is based on the Greenhouse Gas (GHG) Protocol and the operational control approach. The base year is 2022. The base year chosen was 2022 because that was the year greenhouse gas emissions for Scopes 1, 2 and 3 were systematically recorded for the first time.

Explanations of greenhouse gas emissions

Direct greenhouse gas emissions (Scope 1)

Scope 1 covers all direct greenhouse gas emissions (excluding biogenic emissions) of the Repower Group. These include emissions from stationary combustion sources and fuel consumption of vehicles, which are calculated based on the fuel used. Fugitive emissions comprise SF₆ and refrigerants. These are calculated on the basis of weight. Direct emissions from electricity generation depend on the volume of electricity generated and are calculated on an activity basis. Direct emissions from natural gas combustion in Italian plants such as combined-cycle gas turbine power plant are modelled using the plant’s ETS data combined with national standard coefficients (M.A.S.E) and DEFRA factors to increase accuracy. The T&D and WTT components are considered separately in the corresponding Scope 3 categories using the DEFRA factors and the results of Repower’s ISO 14067 study. Biogenic emissions are not included because only very small amounts are involved.

Energy indirect greenhouse gas emissions (Scope 2)

Scope 2 covers the indirect emissions stemming from the Repower Group’s use of electricity and the transmission losses in its own power grid. The emissions are calculated on both a market basis and a location basis The market-based figures are relevant for the climate targets. Emissions at Repower Switzerland are calculated on both a market basis in accordance with electricity labelling and on a location basis in accordance with the generation mix. Repower Switzerland uses the previous year’s electricity labelling for the calculation. Repower Italia uses the Association of Issuing Bodies (AIB) factors both for the market approach (residual mix) and for the location approach (generation mix). In each case, Repower Italia uses an internal estimate for the calculation. The final figures are not available until April.

Other indirect greenhouse gas emissions (Scope 3)

Scope 3 emissions relate to upstream and downstream activities along the value chain (excluding biogenic emissions). These are divided into 15 subcategories according to the GHG Protocol. Repower Switzerland and Repower Italy did a separate materiality analysis in which the relevant subcategories were defined. Given their low share of total emissions, subcategories 3.4, 3.8, 3.9, 3.10, 3.12, 3.13 and 3.14 were not considered relevant for the Repower Group or were disclosed in other categories. Subcategories 3.6 and 3.15 are only calculated for Repower Switzerland; for Repower Italia, these subcategories were not considered relevant given to their low share of Repower Italia’s total emissions. Biogenic emissions are not included because only very small amounts are involved.

3.1 Purchased goods and services: Repower does a spend-based calculation. At Repower Switzerland, for 2022 and 2023 only purchased goods and services at Repower AG were included. Since 2024, data for all Repower companies have been included. The data for 2023 and 2022 were not adjusted, because the change accounts for less than 0.1 per cent of subcategory 3.1 and is therefore negligible. In addition to purchased goods and services (modelled on the basis of a spend-based calculation), Repower Italia also covers the upstream emissions (WTT) of the natural gas sold in subcategory 3.1, using an activity-based approach.

3.2 Capital goods: Repower does a low-accuracy, spend-based calculation. At Repower Switzerland, for 2022 and 2023 only capital goods at Repower AG were included. Since 2024, the capital goods of all Repower companies have been included. The data for 2023 and 2022 were not adjusted, because the change accounts for less than 1 per cent of subcategory 3.2 and is therefore negligible.

3.3 Fuel and energy-related activities: Subcategory 3.3 includes, firstly, the upstream emissions of purchased fuels, which are calculated on a fuel basis; secondly, the upstream emissions of purchased electricity; and thirdly, the emissions of purchased electricity for end-consumers, which are calculated on a market basis. Repower Switzerland uses the previous year’s electricity labelling for each of these. Repower Italia uses the previous year’s AIB factors for the calculation. For 2022 and 2023, the upstream emissions from Repower Switzerland’s electricity generation were also conservatively counted in subcategory 3.3. Since this led to double counting, since 2024 the upstream emissions from electricity generation have only been included in subcategory 3.1 or 3.2.

3.5 Waste: Emissions from waste are calculated on a weight basis. If no information on waste is available, Repower Italia uses average Italian recovery factors from the Il riciclo in Italia report.

3.6 Business travel: Repower Switzerland calculates the emissions stemming from business trips based on expenditure. For 2022 and 2023, only business travel at Repower AG was included. From 2024, data from all Repower companies in Switzerland and Germany have been included. The data for 2023 and 2022 were not adjusted, because the change accounts for less than 1 per cent of subcategory 3.6 and is therefore negligible. Repower Italia does not take subcategory 3.6 into account because its share of total emissions is very low.

3.7 Employee commuting: Repower Switzerland calculates emissions using country-specific average data. Repower Italia uses data from an internal study of commuting habits among employees of the Milan office. The emissions for the employees of the Teverola gas-fired combined cycle power plant are estimated by applying an average factor.

3.11 Use of products sold: The subcategory primarily includes emissions from natural gas sold to and combusted by customers in Italy. The emissions are calculated using the same methodology and from the same sources as explained in Scope 1.

3.15 Investments: Repower Switzerland does an activity-based calculation. For power generation assets without operational control, only Repower’s interests are taken into account. Nuclear power plant purchase rights are not included, as Repower has no interest in them. Repower Italia does not include subcategory 3.15 as it does not have generation assets without operational control.

Other: For the 2022 and 2023 reporting years, Repower Switzerland calculated the emissions for categories 3.4 (upstream transport and distribution), 3.8 (rented and leased tangible assets) and 3.12 (end-of-life treatment of sold products); these are summarised in the category Other. These subcategories are no longer be calculated for the 2024 reporting year because they are currently not considered relevant.

Emission factors used

BEIS Department for Business, Energy & Industrial Strategy (formerly DEFRA), IPCC Intergovernmental Panel on Climate Change, Intep Greenhouse Gas Emission Factors for the Building Sector, PCAF Partnership for Carbon Accounting Financials, AIB Association of Issuing Bodies, Exiobase, ecoinvent, M.A.S.E. Ministero dell’ambiente e della sicurezza energetica, ISO 14067, Stromkennzeichnung.ch, Swiss Post. Greenhouse gas emissions are expressed in CO₂ equivalents (CO₂e), based on their global warming potential over a 100-year period (GWP100). The values for global warming potential are based on the Fourth, Fifth or Sixth Assessment Report (AR4, AR5 or AR6) of the Intergovernmental Panel on Climate Change (IPCC). The analysis includes at least the following greenhouse gases: carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O).

Intensity of power generation

The intensity of electricity generation at Repower is calculated on an operational control basis. The base year is 2022.

Energy consumed within the organisation

Explanations regarding energy consumption

Fuel consumed: Fuel consumed includes petrol and diesel consumed by vehicles and generators, as well as natural gas consumed by Teverola combined-cycle gas turbine power plant and heating systems. At Repower Switzerland, diesel and petrol consumption is determined on the basis of fuel supplier invoices. At Repower Italia, consumption is recorded on the basis of estimates. These estimates are based on the maximum annual mileage of the individual vehicle types.

Other energy consumed: Other energy consumed includes the company’s own electricity consumption for administration, the grid, power generation and pumping energy. The electricity consumption of sites in Switzerland that are outside Repower’s supply area and of externally charged electric vehicles is estimated. Heating and cooling energy are included in electricity consumption. Repower does not consume any steam.

Sales: At Repower Switzerland, sales covers the amount of energy supplied to basic supply customers, free-market customers and trade customers. Since 2024, the actual volume consumed has been used for free-market and trade customers. For basic supply customers, the gross volume continues to be reported, as complete information on their own production is not available. At Repower Italia, sales covers the total amount of energy sold to end users. In addition, the electricity (gas) sold is reported separately, as gas sales are significant at Repower Italia This presentation is for transparency purposes and does not correspond to the GRI standards.

Total energy consumed: Reporting total energy consumed in accordance with the GRI is of limited use for an energy company such as Repower, as its core business is the generation of energy for sale. Accordingly, the amount of energy sold significantly exceeds the amount of energy consumed by the company itself. Total energy in accordance with the GRI is therefore not reported.

Work-related injuries

Explanations regarding work-related injuries

The figures cover employees of the Repower Group. They include the working hours of all employees of the Repower Group, including those who left during the year. A total of 1,303,818 hours were worked from 1 January to 31 December 2025. From 2025 onwards, the working hours of members of the Executive Board and divisional heads are estimated. The data for Year 2022 and 2024 were not adjusted, because the change accounts for less than 5 per cent and is therefore negligible.The rate of work-related injuries is calculated on the basis of 200,000 hours worked. Repower does not provide any information on work-related injuries to workers who are not employees. Since they are insured through their own employers, no data is available, and Repower does not receive any accident reports.
