21 1954 First cogeneration plant (CHP) using a steam engine from Spilling 1960 First steam turbine (steam generation with coal) 1977 Expansion of the cogeneration plant to an electrical output of 6.3 MW (light oil, later natural gas) 2000 Gas and steam system with an electrical output of 14 MW and a thermal output of 50 MW; power is fed into the public grid What is a gas and steam system? In a gas and steam system, natural gas is converted into electrical power and heat in a two-stage process. The gas first drives a gas turbine with a generator to produce power. The flow of exhaust gas from the gas turbine is used to generate high-pressure steam. In a second stage, this then drives a steam turbine with a second generator. Thanks to this system MEGGLE can remain operational at the site in Wasserburg even if there is a general power failure. Example: The CHP power plant in Wasserburg Processing and drying whey in Wasserburg is a highly energy-intensive process. In addition to its attempts to keep the energy consumption in the production processes to a minimum, MEGGLE also opted for CHP power generation methods very early on in its development because it is the most efficient form of energy generation. Today, MEGGLE operates one of the most efficient CHP power plants in Germany with an overall efficiency level of 90% compared to conventional power generation methods with rates of 30–40%. Thus, MEGGLE is making a significant contribution to climate protection and the turnaround in energy policy. It actually manages to feed enough power into the public grid to run a small town with approx. 10,000 households. 3. Environment
