Wastewater T.P. Biogas Utilization

The City is interested in a sales agreement contract for the sale of WWTP biogas, and this RFP is requesting proposals potentially covering a large spectrum of projects which could range from 1) purchase of the raw biogas at the fence line, at one end of the spectrum,  to 2) cleaning the raw biogas to produce clean biomethane for injection into a natural gas pipeline, at the other end of the spectrum, or 3) any other beneficial proposed projects in between, including proposals combining City biogas with other area biogas sources. The City would also consider proposals including cogeneration of electricity and/or waste heat [utilization by the City].
