A pioneering solution
The original Jenbacher CHP plant in the Heizwerk Süd heating plant comprised one J312 and one J416 and was operated purely on a heat-driven basis to align with the heat demand in the district heating network. Stadtwerke Bad Säckingen’s decision to expand came at just the right time to install the new J420 E technology. Adding the three Jenbacher units – an additional J416 and two latest generation J420 E engines – has increased total output to 6.2 MW of thermal and 5.7 MW of electrical energy. A large buffer storage system with a capacity of 264,172 gallons (35,314 ft3) has been constructed, allowing the system to be operated on a power-driven basis now too. This means that the individual CHP system modules are turned on and off depending on the power demand in the public grid and the feed-in of solar and wind-generated power, thus ensuring power supply even during the “dark doldrums.”
Adding the three Type 4 Jenbacher CHP systems increased the output of the Heizwerk Süd heating plant by a factor of three, meaning that more than 4,000 households can now be supplied with electricity and a further 1,000 with heat. According to Stadtwerke Bad Säckingen, using the biomethane-powered Jenbacher CHP systems to generate both power and heat saves some 3,600 metric tons of CO2 emissions compared to conventional heat generation using fuel oil. The electricity produced is fed into the public grid, while the thermal energy given off in the process is transported via the existing district heating network to the homes and public facilities connected to it.
