Explanation
* The wastewater treatment process creates biogas that is approximately 60% methane. Currently the biogas is being used for digester heating and the excess is burned off.
* The project will change the process by burning the biogas in a specialized engine that will run a generator producing power, and heat off of the engine will be used for heating the digesters.
* The engine will produce close to 8,760 kW-hours, off-setting about one-sixth of the plant power energy use and save approximately $350,000 in power costs annually, leading to a 10-year project payback from savings.
* On December 22, 2015, the City issued an Invitation to Bid for Combined Heat and Power Improvements at the McAlpine Creek Wastewater Treatment Plant; four bids were received from interested service providers.
* State Utility Contractors, Inc. was selected as the lowest responsive, responsible bidder.
* The project is anticipated to be completed in one year.
* The total project cost is approximately $4.5 million, including design and purchase of the geneator.
* The project will be partially-funded by the Clean Water State Revolving Fund loan approved by City Council on June 22, 2015.
