ABOUT US

ESS Modern AG
Swiss Quality Since 2001

We have been your partner for energy efficiency and power quality for over 25 years. Swiss engineering for industrial applications worldwide.

Our Mission

The low-voltage grid experiences significant fluctuations due to increasing use of power electronic consumers and rapidly growing cross-feeding from wind power and photovoltaic systems. This results in grid failures as well as voltage and frequency fluctuations.

Our ESS systems create more operational and process reliability, stabilize the grid, reduce electricity costs and extend the lifespan of your equipment – with a contractual guarantee.

Our Vision

Our vision is to become the leading service provider for energy efficiency and the number one partner for industry, commerce and public institutions when it comes to ensuring safety, sustainably saving energy, reducing CO₂ emissions, permanently lowering costs and thereby sustainably strengthening the future viability and performance of operational facilities.
