California's Glendale Water & Power has executed a full deployment license agreement for the use of DVI's EDGE® advanced grid optimization solution.
"Last fall, we began our Volt/Var optimization (VVO) pilot with DVI," said Steve Zurn, Glendale Water & Power's general manager. "The EDGE® platform promised to effectively plan, manage, and validate energy savings---and it delivered on that promise. During the next five years, as we ramp up deployment to 68,000 meters, we expect savings of $3.8 million."
GWP selected one feeder with approximately 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 megawatt hours (MWh) without requiring a change in customer behavior; when fully deployed, GWP expects to save more than 14,500 MWh each year.
EDGE seamlessly 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.
