PV-Anlage bei untergehender Sonne

Engine of the regional energy transition

The energy transition did not require any strategic reorientation on our part. On the contrary: we, Stadtwerke Gießen, have been heralding it for a long time - and are therefore also your contact for the energy transition at home.

Smartphone in den Händen

Energy efficiency, electromobility, smart technology: the topic of energy is becoming increasingly relevant. As a municipal utility, we have the right answers to the challenges of the future with our products and solutions. We are happy to support and advise you.

Committed to a Central Hessen worth living in

The opportunities for organising leisure activities are an important criterion for choosing a place to live these days. Giessen and the region have a lot to offer in this respect. We make our contribution to this every day. By getting involved in sport, culture and social issues.

ITEE - Interlocking theory and practice in the Central Hesse region

The Institut für Transformationsaufgaben in der Energiewirtschaft und Energietechnik e. V., or ITEE for short, was founded in 2023 on the initiative of the Technische Hochschule Mittelhessen (THM). The association now includes 15 municipal utilities from the region - including Stadtwerke Gießen. SWG board member Matthias Funk is one of the chairmen.

Together with its association members, the ITEE provides students with in-depth insights into the world of utilities. The study of MINT subjects
subjects is thus enriched by training for the transformation tasks in energy supply companies (EVU). Heat and energy planning is realised in project work together with experts from the energy supply companies and the scientific management. We want to arouse students' interest in the tasks of energy suppliers and thus attract employees with a view to the future.
