Energy suppliers become energy producers: a 20V Series 4000 Combined Heat & Power Module (CHP) from MTU Onsite Energy has just been delivered to the public utility company of Neuburg an der Donau, a major district town located on the Danube in Germany. The 20-tonne powerhouse is to go into service on the site of glass manufacturer Saint-Gobain Oberland AG, which occurs under the name of Verallia, from March 2016. The Bavarian public utilities purchased the new CHP plant to respond to the needs of growing numbers of heat consumers in and around the city.
The gas-powered CHP module now forms the heart of the new energy centre and is deployed for power generation when demand peaks. Waste heat from the gas engine is fed into the district heating system run by the Neuburg public utilities and is distributed to on-line consumers. The electrical efficiency of the gas genset is 43%. With constant heat consumption, the plant boasts 91% overall efficiency.
Aim to reduce the city's CO2 emissions by 30% by the year 2020
Energy-intensive enterprises in Grünau, a local industrial park, already feed their
waste heat into the existing district heating network – supplying thermal energy to consumers in the vicinity such as Audi and the German armed forces. The aim is a reduction of the city's CO2 emissions by 30% by the year 2020. "The gas-powered CHP kicks in when more heat is needed than Saint-Gobain Oberland AG can deliver from its waste heat, and also when power demands peak," explained Richard Kuttenreich, head of the public utilities.
The power plant building has been designed to accommodate a second CHP plant. This is because the public utilities wish to be well prepared should more industrial customers begin to take an interest in sustainably produced energy. Neuburg public utilities also deploy two CHP modules from MTU for the local open-air swimming pool, and a further two at the city's St. Elisabeth hospital. The latter are installed in the hospital boiler-house for the supply of heat and power, with waste heat fed into the district heating network run by the public utilities.
