California's Glendale Water & Power, in collaboration with Dominion Voltage Inc. (DVI), a grid-optimization unit of Dominion Resources, has executed a full deployment license agreement for the use of DVI's EDGE grid optimization solution.
GWP selected one feeder with about 3,800 electric meters for the pilot. DVI and GWP monitored the system and calculated energy savings from October 2014 through November 2014.
The testing validated the expected energy savings of 2.95 percent, well within the anticipated range of 2-4 percent. This reduction resulted in a savings of 87 MWh without requiring a change in customer behavior; when fully deployed, GWP expects to save more than 14,500 MWh each year.
EDGE integrates into a utility's existing IT infrastructure and can obtain voltage readings from the existing AMI system. EDGE optimizes the utilities' field devices by issuing commands over an existing wide area network to optimize the distribution system voltage.
