State Energy Agency ThEGA helps to reduce energy consumption & CO2 emissions in Thuringian municipalities

The energy transition poses great challenges for municipalities and districts, whilst at the same time offering potential for energy savings and climate protection. The Thuringian Energy and GreenTech Agency ThEGA helps to solve these challenges and to explore avenues where there is potential to do so in a targeted and sustainable way.

The challenge: Finding and exploiting potential for savings

Municipal buildings such as town halls, schools or sports halls often consume more energy than necessary. By regularly checking building technology and consumption data, up to 15% of these costs can be saved without investing in new technology or renovations. Modern mobility concepts and optimised street lighting can reduce these costs even further.

Frequently, these potentials are not being exploited, often due to a lack of time, knowledge and human resources. ThEGA supports municipalities in saving energy, costs and CO2 emissions and in building up knowledge and structures for energy management.

The goals for effective climate protection in municipalities

  • Exploit potential for effective climate protection in Thuringian municipalities
  • Reduce energy costs and energy consumption in Thuringian municipalities
  • Imparting (technical) knowledge and building structures for municipal climate protection
  • Enable knowledge transfer and exchange of experience between municipalities

“Energy management helps the environment and city treasury.”

Professor Dieter Sell ThEGA Managing Director

“Thuringian cities, municipalities and districts are key players in climate protection and energy efficiency. As the state energy agency, we are working to ensure that climate-friendly energy use is a natural part of daily business for public administrations. We have already trained energy managers in more than 50 districts and municipalities and shown that energy management is worthwhile for the city treasury and the environment.”

    Tools, workshops and e-guides for climate protection


    Energy managers trained by ThEGA and the online tool “KomEMS” provide support in saving energy in municipal buildings and in setting up their own energy management.


    ThEGA advisory services and workshops support municipalities in the energy-efficient conversion of street lighting.


    ThEGA trains municipal employees to become e-guides in order to make mobility in municipalities environmentally friendly and future-oriented.


    The network of municipal climate protection supports the work and exchange of municipal climate protection managers in Thuringia and initiates joint projects.

    Results: Knowledge transfer creates innovation in energy management

    ThEGA has trained more than 70 energy managers who apply their new knowledge on a daily basis and take care of energy management in their municipality. The “KomEMS” online portal supports them in this. It was awarded the German Innovation Prize for Climate and Environment and is now in use in ten federal states.

    In addition, ThEGA has participated in the replacement of more than 50,000 street lights in Thuringia and has trained more than 30 e-guides, who are shaping the transport transition in their municipalities and planning the mobility of the future. The ThEGA network for municipal climate protection brings together more than 20 Thuringian climate protection managers, facilitates professional exchange and initiates joint projects and actions.
