WINGAS, a joint venture of Gazprom and Wintershall, and E.ON Energy Projects have commissioned the new high-efficient combined heat and power (CHP) plant, based on natural gas. The plant, located right at the landing terminal of the Nord Stream pipeline in Lubmin, Germany, has the useful heat output of about 47 megawatts (MW) and an electrical output of about 39 MW.
The plant annually generates up to 200,000 megawatt hours of electricity, enough to provide a secure supply for 50,000 households annually. This innovative unit reaches full load capacity in just ten minutes due to an extraordinarily high efficient gas turbine SGT-750, developed by Siemens.
This turbine has an extraordinarily high efficiency rate, which means it functions extremely economically and in an environmentally friendly manner, and has the shortest maintenance time in its performance class.
The neighboring Nord Stream pipeline provides reliable supply of natural gas right in this location.The waste heat generated in the gas turbine is used to reheat the gas, which cools down while traveling through the subsea pipeline. Due to the combined generation of electricity and heat, the overall efficiency of the plant is over 85% that allows saving around 40,000 tons of CO2 a year compared to the separate generation of heat and electricity. The CO2 emissions saved are comparable to emissions of 13,000 cars.
WINGAS Managing Director Ludwig Möhring underlines that «the unique flexibility of the plant in Lubmin highlights the contribution that natural gas and natural gas technologies can make to ensure the success of the energy transition in Germany».
