Essex Junction Municipal Biogas Generator
Essex Junction Municipal Biogas Generator
NativeEnergy's customers helped build a renewable biogas generator constructed in the summer of 2003 at the Essex Junction Wastewater Treatment Facility in Vermont. This project captures methane gas and uses it to fuel two 30 kW electricity generating turbines. The methane is produced through the anaerobic digestion of municipal sewage sludge. Just over half of it had been being burned to provide necessary heat to the digesters, and the rest was simply burned away to avoid release of the methane into the atmosphere. Instead, the project now burns all this methane to generate approximately 350,000 kWh of electricity per year, which is used to power pumps, grinders and other process equipment. It also captures the heat produced when the methane is burned for the turbines, and uses it to heat the digester tanks, getting two benefits - electricity and heat - from the same methane. All the electricity the turbines generate would otherwise have been drawn from the grid. By producing this electricity, the project reduces the total amount of electricity generated for the grid, much of which would have been generated by burning fossil fuels.
