Our shared goal
Implementing the energy transition locally
We support cities and energy suppliers in heat planning and integrated grid planning. This includes analyzing existing heat sources, defining target scenarios, and developing a heat transition strategy. The objective is to achieve a climate-neutral heat policy by 2040, with interim targets set for 2030.
As an easy entry point into the energy transition, our web-based photovoltaic configurator solarfind has proven successful in many municipalities and cities. It enables local homeowners to independently assess the photovoltaic potential of their rooftops and estimate the associated costs. By integrating local craft businesses, implementation is fast and straightforward. In these projects, municipalities and cities save up to nearly 10,000 tons of CO₂ per year.
Our vision is to become a comprehensive solution provider for the optimization of energy systems. That is why we always tailor our joint projects individually to your service area and specific needs.
