The Smart Grid Investment Model (SGIM) is designed for use by electric cooperatives, municipal, and other public utilities. It allows users to: (1) identify each technology and program that fits within the smart grid purview; (2) identify benefits of each technology/program including cost savings, peak kilowatts, and hourly load profiles over the next 20 years; (3) identify technology, installation, program, and management costs based on utility and customer characteristics; and (4) compare benefits and costs to determine investment returns.
