Department of Energy


This impact analysis report presents information on the 26 SGIG projects that are installing devices and systems for voltage and volt-ampere reactive (VAR) optimization (VVO), the types of devices and systems being deployed, and deployment progress to achieve one or more of the following objectives: (1) lowering distribution voltage levels during peak periods to achieve peak demand reductions, (2) reducing voltage levels for longer periods to achieve electricity conservation, and (3) reducing energy losses in the electric distribution system. Expected benefits include deferral of capital expenditures, energy savings, and greater operational flexibility and efficiency.

The Department of Energy's Office of Electricity (OE) recognizes that our nation's sustained economic prosperity, quality of life, and global competitiveness depends on an abundance of secure, reliable, and affordable energy resources. OE leads the Department of Energy's efforts to ensure a resilient, and flexible electricity system in the United States. Learn more about OE >>
