Visit to Green Power Aarau AG – Biogas Meets Precision Measurement Technology

24. Sep 2025

Yesterday, we had the opportunity to take a behind-the-scenes look at a true flagship facility: Green Power Aarau AG operates one of the most modern biogas plants in Switzerland. A drone shot of the site highlights the impressive scale and complexity of this infrastructure.

From regional green waste, climate-neutral biogas is produced here. This not only generates electricity and heat but is also directly fed into the natural gas grid. Each year, around 1,600 households are supplied with renewable energy, making a significant contribution to the regional circular economy and CO₂ reduction.

During an extensive tour, Mr. Markus Regez, Managing Director of Green Power Aarau AG, guided us through the facility. With impressive expertise and visible passion, he explained the complex processes – from the fermentation of organic waste to the upgrading and injection of biomethane into the grid.

A special highlight for us was seeing our own measurement device in action: In the upgrading facility, the gasQS static continuously monitors the methane concentration. This precise measurement ensures that the biomethane meets strict quality requirements before it is fed into the grid. The picture shows Mr. Siragna and Mr. Regez in the upgrading facility, right where the device is in operation.

We sincerely thank Mr. Regez for his valuable time, the in-depth insights, and the inspiring exchange. Green Power Aarau AG is a striking example of how modern technology, dedication, and sustainability can go hand in hand – a true role model for the energy future.
