Water & Wastewater
Municipal wastewater treatment facilities were selected as a focus of LBNL’s OpenADR research because these facilities are energy‐intensive and have significant electricity demand during utility peak periods. Many wastewater treatment facilities have already implemented energy efficiency measures that can provide a base for participation in OpenADR programs and tariffs.The first phase of this research, a scoping study, investigated the efficiency and DR potential in industrial wastewater treatment in California. Current efforts in this area include continuing field tests to enhance the understanding of open automated demand response opportunities in wastewater treatment facilities, by way of a case study at San Francisco South-East Wastewater facility, to follow up the San Luis Rey case study published in August 2010.
The objective of this project was to estimate the water supply related peak electrical demands for investor owned electric utilities in California, based on data from the California Energy Commission and California investor owned utilities. Water supply related electrical demands exceed 2,000 megawatts on summer peak days in California. Agricultural groundwater and surface water pumping represent 60 percent of the total water supply related peak day electrical demand, with water agency demands representing the remaining 40 percent. Over 500 megawatts of water agency electrical demand is used for providing water/sewer services to residential water customers. This study also forecasts future peak day electrical loads and estimates peak demand impacts of population growth and the impact of potential demand reduction programs.
