Energy transition

Repower facilitates implementation of the energy transition in Italy and Switzerland in three areas: renewables, energy availability and supply reliability, and energy efficiency. Repower is going about this by systematically expanding and modernising its portfolio of renewables. At the same time, targeted expansion and ongoing renovation of the grid infrastructure will boost long-term security of supply.

Impacts

Renewables: Repower helps implement the energy transition by investing profitably in renewable energies and developing energy storage projects, thereby supporting ongoing electrification and decarbonisation efforts. However, the generation of renewable energy at hydropower, wind power and solar power facilities can also have negative effects, such as increased land use (see Changes to biodiversity and landscape).

Energy availability and reliability: A reliable electricity and gas supply is essential to the economy and society. In addition to a loss of comfort, power cuts can also result in high costs and losses in manufacturing processes and even jeopardise lives (e.g. in healthcare).

Energy efficiency: The energy efficiency of power plants and the distribution grid determines the energy lost in the generation and distribution of energy and has a direct influence on the costs for customers. By providing efficiently generated and distributed energy, Repower makes a contribution to the economy.

Risks

Renewables: The expansion of renewables is changing the electricity system and posing new challenges in terms of grid stability and security of supply. At the same time, Repower is also focused on the reputational risks: accelerated expansion must not be to the detriment of the landscape and biodiversity nor ignore local stakeholders.

Energy availability and reliability: Power cuts can be costly for Repower and its customers, especially if they are prolonged. If energy that has already been sold is not sufficiently available, procuring energy to replace it can be expensive.

Energy efficiency: High efficiency losses along the value chain increase Repower’s operating costs and thus reduce profitability.

The risks of power supply system failures, damage to generation assets and distribution networks, unexpected fluctuations in energy prices and unexpected changes in the availability of natural resources are part of the Repower Group’s risk and control assessment (see Introduction).

Guidelines and due diligence

Renewables: In accordance with its strategy, Repower is striving to generate 100 per cent of its own production from renewable resources in the long term.

Energy availability and reliability: To ensure a reliable supply of electricity, Repower Switzerland complies with the requirements of the law and is an active member of the Association of Swiss Electricity Companies (VSE), hydrosuisse and other industry associations. The quality of supply is assessed and monitored annually by the Swiss Federal Electricity Commission (ElCom) on the basis of standard international indicators.

Measures

Renewables: In Switzerland, Repower generates most of its own electricity at hydropower facilities. The existing hydropower plants are expertly maintained. Repower systematically modernises existing plants to increase their performance. The company is also pushing ahead with the construction of new hydropower facilities such as Chlus power plant. At the same time, Repower is continuing to expand solar power capacity in Switzerland. The aim is to equip all suitable Repower buildings with solar installations. Repower Italia is also gradually expanding its portfolio of renewables and optimising the efficiency of its existing facilities. It has a total of more than ten wind farms, 23 solar installations and two small hydropower plants with a combined total generation capacity of 128 MW.

Energy availability and reliability: Targeted grid expansion makes it possible to further advance the energy transition through renewables. Repower Switzerland’s strategic target grid planning ensures the early integration of renewables and guarantees a stable supply. Repower Switzerland has proven specialists and tested processes to ensure a reliable supply of power. The company has a grid control centre staffed around the clock, all year round which monitors the electricity grids, as well as regional on-call organisations with specialists to remedy disruptions to the electricity supply that can occur, for example, as a result of storms. Every year Repower also takes part with other operators in Swissgrid grid redevelopment training.

Energy efficiency: The Repower Group works to improve the efficiency of its power plants, distribution grid and its own energy consumption, and offers energy efficiency services for its customers. The smart meter rollout is currently under way in Repower Switzerland’s supply area with SMARTPOWER. This innovative measurement and control system was developed by EVUlution AG, which originated at Repower. As of the end of 2025, around 45 per cent of the meters in the grid area were smart meters. These smart meters facilitate the energy transition by enabling customers to optimise their consumption behaviour via a digital customer portal. The metering data obtained also helps to better understand grid load and make planning grid expansion more efficient. Further information on the current status of the smart meter rollout can be found in the Overview of the year.

In the field of electric mobility, Repower sold its Swiss private vehicle charging infrastructure business to AVIA Volt in April. Repower Switzerland continues to operate in electric mobility and will focus in future on high-performance charging solutions for heavy goods vehicles and public transport. Repower E-Mobility plans, designs and supports the construction of durable and robust hardware for depot and intermediate charging of electric buses and HGVs, and also offers customers optimised energy management.

Repower Italia is helping actively promote electric transportation by developing products such as GIOTTO and SYMBIOSIS, which can be used to charge electric vehicles, and through membership of the Repower Charging Net. Repower Italia organises events dedicated to the topic of sustainable transport, produces and regularly runs a podcast on energy issues, and publishes an annual white paper on electric mobility.

Stakeholder engagement: When planning new projects or renovations that affect the environment or local infrastructure, Repower Switzerland involves the relevant stakeholders at an early stage. Stakeholder feedback is collected at information events in the regions and, where possible, actively incorporated into the development process.

Measuring effectiveness

Renewable energy in power generation

Repower Switzerland generates 100 per cent of its electricity from renewable resources. The share of renewables in Italy is 73.9 per cent. Across the group, 90.5 per cent of the electricity generated in 2025 came from renewables. In 2024 the figure was 59.9 per cent. The significant increase in the share of renewables over the previous year is due in particular to a prolonged outage at Teverola gas-fired combined cycle power plant. Production at Teverola was very low overall in 2025, which led to a marked increase in the relative share of renewables in the total volume generated.

Compared with the previous year, in 2025 17.3 per cent less electricity was generated at hydropower plants and 11.5 per cent less electricity by wind turbines overall. The decline in hydropower is the result of weak snowmelt in the spring and below-average precipitation throughout the rest of the year This contrasts with an increase of 40.3 per cent in solar energy, which is mainly due to the commissioning of new solar plants in Melfi. This figure takes into account own production without minority interests, Repartner Produktions AG and purchase agreements.

Supply security: In 2025, the System Average Interruption Frequency Index (SAIFI: the average number of interruptions experienced by an end-consumer) for the Repower Switzerland distribution grid was 0.54. The System Average Interruption Duration Index (SAIDI: average outage duration for each end-consumer served) was 12.59 minutes in 2025, making it the best year since the introduction of the analysis in 2014.

Development of charging points for electric vehicles: In 2025, 884 new charging points for electric vehicles were sold in Italy. Repower Italia has thus created a network of around 8,180 charging points throughout Italy, an increase of 12 per cent over the previous year. Repower E-Mobility was launched in Switzerland in 2025 and sold 137 charging points for electric buses and HGVs in the year under review.
