Smaller Carbon Footprint with CHP: Stendal Municipal Utility Provider Modernizes Cogeneration Power Plant with MWM TCG 2032B V16 Gas Engines
Mannheim, May 20, 2021
After about 25 years of operation and 100,000 operating hours, the municipal utility provider of the city of Stendal, Germany, realigned its heat supply concept and replaced the existing technology in its cogeneration plant on Schillerstrasse with modern, gas-fired cogeneration power plants. The goal is to enable even more sustainable and eco-friendly supply of the city area with heat and power. To increase the efficiency of the energy generation, three new cogeneration power plants from the manufacturer SES Energiesysteme GmbH were equipped with three powerful MWM TCG 2032B V16 gas engines. Thanks to the modernization and flexibilization, the municipal utility provider is able to ramp up the plant even faster and more efficiently and significantly reduce the carbon footprint.
Cogeneration for Sustainable Energy Generation
According to the municipality’s energy and climate protection concept, emissions are to be reduced by about 75 percent by 2035 compared to the reference year 1990. The goal is to supply the entire city area with energy from regional regenerative sources. To reach this goal, the Stendal municipal utility provider has decided to modernize its central cogeneration power plant, which supplies the city with heat and power. The municipal utility provider has already been using combined heat and power (CHP) generation since the 1990s. Back then, the natural gas-fired 18-cylinder marine diesel engines installed to replace the previous engines were already very progressive. Over the past 25 years, the municipal utility provider has already been able to save some 2.5 million t of carbon dioxide by using combined heat and power generation instead of separate heat and power generation.
Getting the Municipal Utility Provider’s Heat Concept Ready for Tomorrow
After more than 20 years of permanent operation with about 100,000 operating hours and in view of the demographic changes and current environmental requirements, the municipal utility provider of Stendal has realigned and adapted its entire heat supply concept. The cogeneration plant has been modernized as a central thermal plant and been equipped with three modern SES-HPC 4500 N cogeneration power plants. Each of them is equipped with a highly efficient MWM TCG 2032B V16 gas engine. Each of these MWM gas engines delivers 4.5 MW of electrical and thermal output and is designed for permanent operation. The targeted useful life is 160,000 hours. The emission limits of the cogeneration power plant are checked and complied with by means of oxidation catalysts. The cogeneration power plant on Schillerstrasse has also been furnished with a heat storage unit. “We’ve invested some €15 million in the site”, says Thomas Bräuer, Administrative Director of the city’s municipal utility provider, in an article in “E&M” magazine. “The financing mainly took place on the basis of the German Combined Heat and Power Act.”
The modernization project took one and a half years until the new cogeneration power plant was ready for permanent operation. “The new, modern gas engines run on natural gas”, explains Sven Krüger, Managing Director of cogeneration power plant manufacturer SES Energiesysteme GmbH in “E&M”. “In terms of the operation, the MWM engines are much more flexible than the municipal utility provider’s old engines, in line with today’s requirements for efficient and sustainable energy supply. Moreover, their maintenance intervals are much longer, and they have a significantly longer useful life, which benefits the total cost of ownership.”
MWM TCG 2032 V16 Gas Engine for Even Faster Ramp-up
The MWM TCG 2032B V16 gas engine has an output of 4.5 MWel and a fast ramp-up option. Due to the fluctuating capacities of renewable energies such as wind or solar energy, the importance of this technology is on the rise. The fast ramp-up option allows the operator to switch between normal and fast genset ramp-up in a flexible manner. Whenever necessary, it thus takes less than five minutes from the ramp-up request to 100 percent network load.
