Roof-mounted photovoltaic (PV) systems, including a modest amount of battery storage, can provide firm peakdemand reductions for commercial buildings. The costeffectiveness of a dispatchable peak-shaving PV system is determined by the demand reduction, which is a function of the solar resource and the building's load profile, and electric utility rates. The analysis presented in this paper identifies building types and regions, from a database of eleven electric utility service territories distributed throughout the country, for which the economics of dispatchable peak-shaving PV are most favorable.
