Energetics collaborated with the Sacramento Municipal Utility District (SMUD) to develop “Smart Grid Investment Grant Projects: Public Power Case Studies,” a report on the impact of the U.S. Department of Energy (DOE) Smart Grid Investment Grant (SGIG) program on public power utilities. The effort was funded by the American Public Power Association’s (APPA’s) Demonstration of Energy and Efficiency Developments (DEED) program. The report shares experiences, successes, lessons learned, and best practices collected from a comprehensive review of public power utilities that received SGIG funds. In addition to assessing some of the impacts of the SGIG program, it is designed to inform and assist other public power utilities considering their own smart grid deployments.
The SGIG program, funded by the American Reinvestment and Recovery Act (ARRA), was designed to accelerate the modernization of electric transmission and distribution systems and promote investments in smart grid technologies, tools, and techniques. SGIG awards funded projects in five technology categories: advanced metering infrastructure (AMI), customer systems (CS), electric distribution systems (EDS), electric transmission systems (ETS), and equipment manufacturing. The program awarded 99 SGIG grants to more than 225 electric utilities and other partnering organizations; public power utilities led 32 of the 99 projects. By SGIG program completion, public power recipients are expected to spend a collective total of $1.18 billion (combined recipient and federal shares).
In profiling those 32 projects, the report reviewed specific smart grid technologies, discussed how municipal utilities can derive substantial benefits as a result of smart grid deployments, and identified challenges that municipal utilities face when deploying smart grid technologies. Discussion included a summary analysis of all SGIG-funded municipal utility projects, a review of key findings that cut across multiple funding recipients, and an in-depth analysis of four municipal SGIG projects: the SMUD, the Central Lincoln People’s Utility District (Central Lincoln), EPB (formerly the Electric Power Board of Chattanooga, Tennessee), and the Cuming County Public Power District (CCPPD).
