A simplified technique for screening utility DSM options for their capacity and operational benefits

Demand-side management (DSM) is becoming a universally accepted means for reducing utility-capacity needs and improving system operational performance. A technique is presented which utilizes an inverted load-duration curve (ILDC) in an efficient way to integrate utility DSM effects properly without using the chronological load-modification process. Such a simplified method will provide the opportunity to screen a large number of DSM scenarios and obtain a reliable estimate of their potential capacity and operational benefits. A few select cost-effective DSM programs may then be chosen and evaluated with supply-side options in integrated utility-resource planning.
