Since 1988 the City of Salem has operated a 650kW cogeneration facility to generate power from biogas produced as a byproduct of wastewater treatment processes at its Willow Lake Water Pollution Control Facility. The system is at the end of its useful life and is undersized for the quantity of biogas produced.
The objectives of the Cogeneration Facility Upgrade project are:
- Maximize the utilization of available biogas produced to produce clean and reliable renewable energy.
- More efficiently and reliably generate electricity from biogas.
- Utilize waste heat from electricity generation.
- Reduce the City’s reliance on non-renewable power sources.
- Provide environmental and economic value to the community and the City’s ratepayers.
- Replace the existing cogeneration system, which is at the end of its useful life.
The project will upgrade the system for cogeneration of power using methane gas generated from the City's wastewater treatment process.
