“Enabling the transition to a renewable world”


We promote developments towards a world with a better quality of life, characterized by significant reductions in CO2 emissions, air pollution and noise. The aim of emost is to provide electrical energy wherever it is needed – regardless of the existing infrastructure. Sector coupling and the associated electrification of (almost) everything is one of the big trend topics of our time and emost will actively contribute to a successful energy transition. So that you can take care of your work, we take care of the necessary supply infrastructure.


The idea for project emost (electro mobile storage) was born in 2017 on the occasion of a workshop conducted by Axpo’s “Renewables” division at the Albert-Heim Hütte in Switzerland. The project objective was to replace diesel generators. Out of the range of identified market niches the initial focus was placed on the construction industry. The project was run in parallel with other regular activities of the Division until a full time team of experts was entrusted with the Butler development in 2019.


emost is embedded in Axpo, the largest Swiss producer of renewable energy and an international leader in energy trading and the marketing of solar and wind power. With our climate-friendly power plant park, 5,000 employees make an important contribution to a sustainable power supply in Switzerland. In over 30 European countries and in the USA, Axpo develops innovative energy solutions based on the latest technologies for its customers.

In line with our company’s motto, emost is also “full of energy”.
