GE Energy Supplies Jenbacher Engines for Energy Park

GE Energy is supplying 40 high-efficiency, JMS 312 units to renewable energy developer, NAWARO Bioenergie AG, Leipzig, for an agricultural biogas project in eastern Germany, near the Polish border. Each of GE’s 500-kilowatt (kW) Jenbacher engines is being installed in separate plants to support the new combined heat and power (CHP) bioenergy park “Klarsee.”

GE’s 40 units will use biogas created during the fermentation of agricultural waste, including maize, crop residues and animal manure. Residual material in the digester can be used as fertilizer. Normally, agricultural wastes decompose gradually to create methane, a potent greenhouse gas. However, by capturing the gas and using it as fuel, less of it is free to escape into the atmosphere. In all, GE’s Jenbacher engines will provide 20 megawatts (MW) of electricity and 22 MW in thermal output. While the engines’ electricity will be sold to the local grid, a separate, specially designed heat-recovery system will deliver the engines’ thermal output to an adjacent fertilizer production facility on the farmland. “GE is very pleased to support this important biogas project, which will help Germany expand its renewable energy capacity and support the European Commission’s goal to develop a more modern, more energy-efficient CHP infrastructure,” said Prady Iyyanki, General Manager of GE’s Jenbacher gas engine business. Since each biogas plant has a maximum electrical output of 500 kW, the projects qualify under Germany’s Renewable Energy Law (EEG) for “feed-in” tariffs and “CHP bonus incentives” for fully utilizing the engines’ heat. Under the EEG, biogas plants are guaranteed a minimum price for supplying electricity for 20 years.
