49Komma8 to build 120 megawatt-hour battery park in Bonaduz, Switzerland

In 2027, le largest battery storage facility in Switzerland will go into operation in Bonaduz in the canton of Grisons. Developed by 49Komm8 AG, the battery park with a performance of 60 megawatts (MW) and a storage capacity of 120 megawatt-hours (MWh) is an investment of the Avadis Anlagestiftung, which is investing in large-scale battery storage for the first time.

49Komma8 AG, which specializes in the project development and implementation of large-scale battery storage systems, is planning and implementing a 60 MW battery park with a storage capacity of 120 MWh in Bonaduz in the canton of Grisons. 49Komma8 has now successfully found an investor for the newly founded "BESS Bonaduz AG".  Avadis Anlagestiftung, which is managed by Avadis Vorsorge AG, will acquire all shares in BESS Bonaduz AG and will continue to rely on the expertise of 49Komma8 AG for the implementation of the project.

Christian Dürr, founder and CEO of 49Komma8 AG, states: "We are proud to have won such an important investor for the Bonaduz battery park as the Avadis Anlagestiftung. This underlines the possibility to achieve sustainable and interesting returns with such promising investments in energy infrastructure".

Aquila Capital, an experienced asset manager in the field of clean energy infrastructure investments based in Hamburg, advised the Avadis Anlagestiftung on its investment decision. "We appreciate the professionalism and efficiency with which 49Komma8 AG has developed the Bonaduz battery park to date. We are therefore convinced that the Swiss battery storage specialist will continue to implement the project with the same precision over the next two years," says Christian Krebs, Head Investment Management Clean Energy at Aquila Capital.

The Bonaduz battery park will be operational in the first half of 2027. It will then be by far the largest battery storage facility in Switzerland. It will be built on a 5,500 square-meter industrial site in the immediate vicinity of a substation and a major hub of national distribution grid. This will ensure an efficient connection of the battery park to the Swiss electricity grid.
