RICHMOND, Va., Feb. 15, 2013 /PRNewswire/ -- Dominion Voltage Inc. (DVI), a
Dominion company, has been awarded a patent for its EDGE^® technology that
enables electric utilities to plan, manage and validate voltage conservation
for grid optimization.

The title of the patent from the U.S. Patent and Trademark Office is "Voltage
Conservation Using Advanced Metering Infrastructure (AMI) and Substation
Centralized Voltage Control."

"Unlike other voltage conservation processes that have been in use for
decades, DVI's EDGE^® technology is the only platform to obtain voltage data
directly from dynamically selected meters at the end-user level," said Phillip
W. Powell, DVI director of Grid Innovations. "This allows for a more precise
and more efficient delivery of electricity to customers."

"The patent for EDGE^® is a game-changer for the industry," said Todd Headlee,
director of DVI. "Many utilities are looking for voltage conservation
solutions. DVI's patent recognizes the unique methodology of the EDGE^®
platform and its capability to reduce energy usage across the distribution

Utilities with AMI can take advantage of this technology and its energy-saving
benefits immediately. For utilities not yet utilizing AMI, the energy savings
that the EDGE^® platform delivers can make the investment in AMI more
affordable. "It's a win-win for both the consumer and the utility," Headlee

The industry standard permits voltage to be delivered at a range from 114
volts to 126 volts, with the center point at 120 volts. DVI's EDGE^® platform
enables the utility to optimize the voltage delivered to the customer towards
the lower end, while still complying with customer equipment performance

For the consumer, EDGE^® can result in reducing the customer's electric bill
by 3-5 percent with no change in the customer's behavior, compared with
savings of 1-1½ percent through traditional voltage conservation programs.
Additionally, with DVI's platform, the reduced voltage levels at the
customer's residence or business result in less stress on electric and
electronic equipment and less waste heat, which is expected to lengthen the
equipment's lifespan.

For electric utilities, DVI's platform is designed to enable them to realize
savings through voltage conservation by reducing their fuel and purchased
power costs. EDGE^® is unique in providing the platform for increased,
sustainable savings. EDGE^® PLANNER works with existing system planning tools
and processes to make the Conservation Voltage Reduction business case circuit
by circuit. EDGE^® MANAGER has been designed to integrate seamlessly into
existing distribution control systems, enabling utilities to improve their
voltage controls without changing or disrupting their existing processes or
systems. EDGE^® VALIDATOR calculates actual savings from EDGE^® or any other
demand-side programs. 

DVI is a leading provider of grid optimization technology providing solutions
for energy efficiency, demand response and volt/VAR control. DVI's patented
approach plans, manages and validates utilities' investments in grid
modernization while delivering significant energy savings to both utilities
and their customers. For more information about DVI, visit the website at
