As new Distributed Generation technologies are brought to the market, new hurdles to successful commercialization of these promising forms of on-site generation are becoming apparent. The impetus to commercialize these technologies has, up to now, been the value and benefits that the end user derives from the installation of Distributed Generation. These benefits are primarily economic as Distributed Generation is normally installed to reduce the customer utility bill. There are, however, other benefits of Distributed Generation other than the reduction in the cost of electric service, and these benefits normally accrue to the system or system operator. The purpose of this paper is to evaluate and suggest methodologies to quantify these ancillary benefits that the grid and/or connecting utility derive from customer on-site generation. Specifically, the following are discussed: reliability in service; transmission loss reduction; spinning and non-spinning reserve margin; peak shaving and interruptible loads; transmission and distribution deferral; VAR support/power quality; cogeneration capability; improvement in utility load factor fuel diversity; emission reductions; and qualitative factors -- reduced energy congestion, less societal disruption, faster response time, black start capability, system operation benefits.
