Alpiq is a power generation, trading and project origination business headquartered in Lausanne, with a portfolio across Europe that includes pumped hydro energy storage (PHES), nuclear, hydroelectric, gas and renewable energy.
The company inaugurated its first fully-owned battery energy storage system (BESS) project in October 2025, a 30MW/36MWh asset in Finland acquired from Merus Power. It was also the first BESS in the Nordics to meet grid-forming (GFM) requirements, according to Alpiq.
This first project’s acquisition was followed by Alpiq’s purchase of two projects of 100MW/200MWh each in France, acquired from the company’s eventual acquisition target Harmony Energy. Within Switzerland, it has experience in trading and optimising batteries, serving as one of two route-to-market (RTM) providers for a 28MW system brought online in 2024 by utility EWS AG and developer MW Storage.
The Alpiq project looks set to become Switzerland’s largest standalone lithium-ion (Li-ion) BESS so far, although the company did not give timelines for its planned construction and commissioning.
What is thought to be the largest announced in the landlocked country to date is a 50-60MW/100MW-120MWh project acquired by infrastructure investor Avadis Investment Foundation in late 2024. At the time of its acquisition, Avadis said construction would begin this year, with COD in 2027.
