What They Do
Alpiq is a leading provider of energy and service offerings in Europe, formed from the merger of Atel Holding AG and EOS S.A. in 2009 (source: companieshistory.com). The company focuses on various technologies, including hydropower, nuclear energy, gas-fired and combined heat and power plants, as well as renewable energies like wind and solar power. Alpiq produces approximately 17,450 GWh of electricity annually, with generation from nuclear energy accounting for 37%, hydropower 31%, and conventional thermal energy 29% (source: wikipedia.org). Its target markets span across Europe, serving customers from industrial companies to public institutions and households, particularly in countries like France, where Alpiq has been active since 2021 (source: alpiq.com). Alpiq differentiates itself through its flexible asset base and independent trading expertise, enabling the company to remain competitive (source: energy-infrastructure-partners.com).
Projects & Track Record
Notable projects by Alpiq include the Gösgen nuclear power plant in Switzerland, in which the company holds a 40% stake and has a capacity of 1,060 MW (source: wikipedia.org). Other significant projects include the Leibstadt nuclear power plant with a 27.4% stake and the Nant de Drance pumped storage power plant, which has been operational since 2022 and contributes to system flexibility (source: energy-infrastructure-partners.com).

The company has also expanded its activities in household electricity and gas supply in France, which has been continuously developed since 2021 (source: alpiq.com). Although no major acquisitions or mergers have been documented after 2022, the previous delisting through the investment from Energy Infrastructure Partners has solidified Alpiq's private structure (source: energy-infrastructure-partners.com).
