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.
