The New York State Energy Research and Development Authority (NYSERDA) estimates that municipal wastewater treatment plants (WWTPs) in New York State consume about 1.5 billion kWh of electricity each year for sewage treatment and sludge management based on the predominant types of treatment plants, the results of an energy use survey, and recent trends in the amounts of electricity WWTPs use nationwide. Electric utilities in New York State have encouraged demand-side management (DSM) to help control or lower energy costs and make energy available for new customers without constructing additional facilities. This report describes DSM opportunities for WWTPs in New York State; discusses the costs and benefits of several DSM measures; projects energy impact statewide of the DSM technologies; identifies the barrier to implementing DSM at WWTPs; and outlines one possible incentive that could stimulate widespread adoption of DSM by WWTP operators. The DSM technologies discussed are outfall hydropower, on-site generation, aeration efficiency, time-of-day electricity pricing, and storing wastewater.
