Energy Optimization Abstract

The goals of energy optimization are to reduce facility energy use to maintain long-term sustainability of energy resources; to minimize facility operating costs; to make sustainable decisions in facility expansion, upgrades, and retrofits; and to reduce carbon, methane, and nitrogen emissions.  But why should utilities consider energy optimization in the first place?   Compelling reasons include (a) an estimated 4% of the energy used in the United States is consumed by the Water Sector. (Means 2004); (b) water and wastewater facilities are energy intensive accounting for up to 35% of municipal energy use. (Consortium For Energy Efficiency); and (c) energy cost as a percentage of total Operations and Maintenance cost are 2% to 35% of budget (AWWARF, Best Practices for Energy Management).

     For a utility to set and to meet energy optimization goals, operators and managers will gain a general understanding of how the water utility is billed by the energy provider.  With this understanding, we will discuss approaches to optimizing energy use through energy audits, benchmarking, energy management systems, and operating efficiencies.

     The Webcast will include case study presentations of distribution system energy optimization projects by Gwinnett County Department of Water Resources, GA and WaterOne of Johnson County, KS.
