With energy. For the region.

Reliably supplying the city and the region is our task, and ensuring a high quality of life is our greatest concern. In addition to electricity, gas, heat and water, we take care of Giessen's local transport and public baths. In the course of the energy transition, we are always looking ahead and making a decisive contribution to shaping a sustainable future. We do this because Giessen and the region are important to us.
