• Stadtwerke Leipzig GmbH has comprehensively implemented PSI's software suite TS-Energy Version 8.3 for the optimization of the district heating system in the city of Leipzig in the short-term and long-term.

• The focus of the optimization software, which has already been in use since 2021, is on automated plant marketing and control in the short-term area. TS-Energy forms the basis for calculating the deployment planning of all assets such as the complex gas CHP plants, district heating network, heat storage and supply contracts.

• The flexibility of the PSI software makes it possible to react to spontaneous changes and requirements in a reasonable time.

• In the long term, TS-Energy is used for the transformation of the district heating network. The optimization calculations form the foundation for profitability calculations and ultimately investment decisions for new assets to realize the decarbonization strategy in Leipzig. The agility allows a large number of calculations to be performed automatically in order to be able to achieve robust results.

• Thanks to a very customer-oriented and cooperative partnership between the Stadtwerke Leipzig GmbH and PSI, the project was implemented comprehensively and quickly.
