Energy management: California’s Glendale Water & Power (GWP), in collaboration with Dominion Voltage Inc. (DVI), a grid-optimization subsidiary of Dominion Resources (NYSE: D), has executed a full deployment license agreement for the use of DVI's EDGE® advanced grid optimization solution.
- Initial project generated energy savings of 2.95 percent
- Expected energy savings upon full deployment to exceed 14,500 MWh per year
- Utility expected to save $3.8 million over the next five years
“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® is the ideal solution to energy efficiency, because it delivers savings to both the utility and its customers by optimizing the distribution system voltage,” said Todd Headlee, director—DVI. “It is also the only solution available that uses AMI data for grid optimization, which gives it the distinct advantage of providing the maximum amount of reliable savings at the lowest cost by using the AMI meter as the voltage sensor.”
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.
DVI is a leading provider of grid optimization technology, providing solutions for energy efficiency, demand response, volt/VAR control, and renewables integration. DVI's patented approach plans, manages and validates utilities' investments in grid efficiency while delivering significant savings to both utilities and their customers.
