Alpiq’s Sustainability Focus
Foreword
2025 has been a transformative year for Alpiq – a year in which our long-term commitment to security of supply, resilience, and sustainability has taken tangible form across all areas of our business. Each project we completed, from hydropower modernisation to green hydrogen production, marks another step forward on our path toward the energy transition.
Our focus on flexibility is crucial for the energy transition. The completion of our first operational 30 MW battery energy storage system (BESS) in Valkeakoski, Finland, and the acquisition of a new 125 MW BESS project in Haapajärvi, Finland, are milestones that strengthen grid stability and enable the integration of renewable energy sources. Furthermore, Alpiq secured a 370 MW BESS pipeline in Germany. Alongside the P2X Solutions green hydrogen plant in Harjavalta – Finland’s first of its kind – we are expanding a portfolio that seamlessly connects power generation, energy storage, and clean hydrogen solutions.
At the core of our efforts is a clear conviction: a reliable and flexible energy system is fundamental to a sustainable society. The successful modernisation of the Mottec hydropower plant in Valais illustrates how we unite tradition with innovation. By upgrading infrastructure that has supplied communities with clean energy since 1958, we are safeguarding the long-term contribution of renewable hydropower to Switzerland’s energy supply. In parallel, we are investing in the efficiency and longevity of our conventional assets, as demonstrated by the upgrade of the San Severo gas power plant, while also enhancing the ecological performance of our hydropower facilities. Projects such as the new fish ladder at Flumenthal and the launch of the Winznau weir renovation highlight our commitment to ensuring that technological advancement and environmental responsibility go hand in hand.
Sustainability, however, extends beyond operations. In 2025, we strengthened our governance and resilience by establishing a new Chief Risk Officer position and an Integrated Assurance function to ensure a holistic approach to risk, security, and compliance. We also rolled out a comprehensive supply chain due diligence process, embedding transparency and responsibility across our entire value chain.
Our people remain at the core of this transformation. Guided by our “Care, Dare & Share” leadership principles, we continue to nurture a culture that empowers employees to innovate and grow. The recognition of our leadership approach as “best practice” by Advance and the University of St. Gallen (HSG) reinforces our conviction that sustainable success begins with empowered people. Since 2022, Alpiq has advanced a cultural transformation grounded in Secure Base Leadership. Through the work of an ever-growing internal community of coaching ambassadors and our certified internal executive coaches, these principles are becoming a core part of how we lead and operate. This commitment to building a sustainable, people-empowered culture has drawn academic interest: IMD has created a teaching case on Alpiq’s transformation, which is used in their executive programmes. Furthermore, in 2025, Alpiq was featured as a European best-practice example for driving sustainable business transformation in a research initiative conducted by IMD and Capgemini Invent.
As we look ahead, we remain committed to balancing energy security, economic performance, and environmental protection. The progress we achieved in 2025 reflects not only technological advancement but also a deep sense of responsibility – to our stakeholders, to society, and to future generations.
Together, we are shaping a sustainable energy future.

Sustainable business statements
The following section presents some specific examples of Alpiq’s actions and achievements in the area of sustainability in order to illustrate its commitment to sustainability and back up its sustainable business statements.
“Alpiq makes a significant contribution to security of supply by providing storage capacity and flexible power production.”
Strategic focus on flexibility: Alpiq acquires a 125 MW BESS
Alpiq is consistently pursuing its growth strategy in flexible systems to pave the way for the energy transition and acquired its third and largest battery project to date. The 125 MW BESS in the municipality of Haapajärvi, Finland, is scheduled to be commissioned in 2027. The project was developed by the Finnish company Pohjan Voima.

Mottec hydropower plant optimised for a sustainable energy future
First commissioned in 1958, the Mottec power plant in the Val d’Anniviers valley in central Valais is at the core of the hydroelectric complex belonging to the company Forces Motrices de la Gougra. In 2025, the revamped Mottec power plant opened, marking the completion of an overhaul project launched in 2018. This upgrade is part of the company’s commitment to ensuring sustainable and efficient power generation and is designed to boost the plant’s generating capacity and flexibility, which are essential for meeting future energy needs effectively.

Efficiency gain at the San Severo gas power plant after upgrade project
In 2025, the San Severo gas power plant underwent an upgrade that significantly extended its operational life and enhanced reliability, flexibility, and overall performance. The project involved replacing most of the main power train components, including the gas turbine, the high-pressure section of the steam turbine, and the generator.
Alpiq’s first operational 30 MW BESS
In 2025, Alpiq successfully commissioned its first BESS in Valkeakoski, Finland, marking an important milestone in executing the company’s strategy to expand the flexible asset portfolio across its core geographic markets. The facility, which began operations in Q3 2025, will enhance grid stability, increase system flexibility, and support the integration of renewable energy sources such as wind and solar.
Inauguration of Finland’s first green hydrogen plant
In 2024, Alpiq emphasised its commitment to climate protection and strengthening security of supply by acquiring a majority stake in P2X Solutions, a Finnish hydrogen pioneer headquartered in Espoo. A major milestone followed in March 2025 with the official opening of the P2X Solutions’ production plant in Harjavalta. Green hydrogen production had already begun successfully in mid-February, marking the first commercial operation of its kind in Finland. The 20 MW electrolysis plant is currently among the largest in Europe, representing a significant step forward in the country’s clean energy transition.
P2X Solutions’ plant secures Finland’s first International Sustainability & Carbon Certification (ISCC) EU RFNBO certificate
P2X Solutions’ Harjavalta production plant has become the first in Finland to receive an ISCC EU RFNBO certification. The certification confirms compliance with strict sustainability requirements for the production of green hydrogen and renewable fuels and enables the supply of certified RFNBO hydrogen with at least 70% lower life-cycle greenhouse gas emissions than fossil alternatives.
“The certification is an internationally recognized proof that we are also a pioneer in green hydrogen in terms of quality standards. The certificate is an important step in creating a market for green hydrogen and clean fuels. I am very proud of this achievement, which P2X’s Greenteam has accomplished together,” states Herkko Plit, CEO of P2X Solutions.
“Alpiq implements mitigation measures to reduce environmental impacts.”
Alpiq Flumenthal hydropower plant: new fish ladder for fish pass opened
Alpiq Hydro Aare AG replaced the fish ladder of the Flumenthal power plant in the canton of Solothurn with a near-natural bypass watercourse measuring 480 metres in length. The modern facility, which has now been officially opened, enables fish in the Aare to safely bypass the power plant and creates new biotopes and spawning habitats. This construction ensures compliance with the revised Waters Protection Act of 2011.
Green light for the renovation of the Wiznau weir
In 2025, the government of the canton of Solothurn granted a building permit for the renovation of the Winznau dam near Olten, enabling construction to begin in summer 2025 and conclude by 2027. The project will preserve and sustainably modernise the more than 100-year-old weir at Alpiq’s Gösgen hydropower plant while delivering key ecological benefits. It includes a new power plant to improve fish migration and around 30 ecological measures across the concession area, such as increasing residual water flow into the old River Aare and enhancing habitats for reptiles and amphibians. Together, these actions will strengthen the ecological balance along the Aare near the Gösgen plant. The renovation is linked to the new concession for the Gösgen hydropower plant, which stipulates that the weir must fulfil higher requirements in terms of earthquake safety and high-water discharge. However, the restoration also entails further modernisation as the new weir power plant will lead to a significantly improved fish pass.
Responsible resource use through Alpiq’s hardware refresh
Alpiq renewed laptops and screens across Switzerland, Italy, the Czech Republic, and the Nordics. As part of this initiative, 3,000 devices were collected and given a second life: 370 laptops were purchased by Alpiq employees, 500 screens were reused internally, and the remainder were sold to external parties. This initiative avoided 28 tonnes of electronic waste and generated a positive financial impact of CHF 75,000, which will be donated to non-profit organisations in all regions where the devices were replaced.
“Leadership That Drives Success.”
Leading in a fragmented world
The world is changing rapidly, and traditional recipes for success no longer work. In response, Alpiq is committed to a coaching-focused management style. “Care, Dare & Share” is our way of creating an environment in which people can develop their full potential. In September 2025, our leadership development approach was recognised as a “best practice” by Advance and the University of St. Gallen (HSG).
“Robust governance principles are fundamental to sustaining a responsible and resilient business.”
Enhancing Resilience with a new Chief Risk Officer position and Integrated Assurance Function
Over the past four years, Alpiq has made remarkable progress in strengthening its resilience, risk management, and security, while fostering a culture of courageous leadership and open feedback. To further support growth across the value chain elements – encompassing Assets, Trading, and Origination – Alpiq introduced a new organisational structure in 2025 with the establishment of an Integrated Assurance function. Under this framework, key units such as Security, Legal & Compliance and Enterprise Risk Management now report to a newly appointed Chief Risk Officer (CRO), who reports directly to the CEO. This integrated assurance model represents a significant step in reinforcing the long-term resilience and sustainability of Alpiq’s business model.
Successful implementation of the new supply chain due diligence process
In 2025, Alpiq rolled out its new supply chain due diligence process to all fully consolidated entities. Under this process, all suppliers exceeding a defined annual spend threshold are required to undergo a comprehensive Know Your Customer (KYC) check. In addition, suppliers must formally accept the new Code of Conduct for Suppliers. The implementation of this process strengthens Alpiq’s commitment to compliance, risk management, and responsible business practices. It enhances transparency, reduces potential risks, and aligns supply chain operations with the highest standards.
