Innovative Heat and Power Supply Concept in Weida

This case study outlines the implementation of an innovative heat and electricity supply concept developed by TWS (Thüringer Wärme Service GmbH) for the Allgemeine Wohnungsbaugenossenschaft eG (AWG) housing cooperative in Weida, Thuringia. The project features a combined heat and power (CHP) unit with an output of 1.6 MWel and 500 kWth, supplemented by a heat pump and an electrical heat generator. The heat pump utilizes both air and geothermal energy, depending on seasonal conditions, with geothermal probes installed at a depth of 180 meters. The project aims to reduce energy costs and carbon footprint, achieving at least 35% of energy from renewable sources, making it eligible for iKWK funding. The study details the collaboration between TWS and Carrier in designing and optimizing the system, including the use of simulation software and advanced control technology. The project is positioned as a model for future energy transitions in similar neighborhoods.
