DVI, a Dominion company that offers its EDGE technology to utilities to plan, manage and validate investments in grid optimization, showcased EDGE 1.2 with its new capabilities at the DistribuTECH industry conference in January.
EDGE is a modular and adaptive conservation voltage management solution enabling utilities to deploy incremental grid-side energy management that requires no behavioral changes or purchases by end customers. EDGE provides significant and sustainable energy savings of as much as 4 percent through integrated planning, execution and validation of grid side energy efficiency management.
Central Lincoln People's Utility District, a leading Oregon electric utility, recently signed an agreement with Landis+Gyr to establish a demonstration Dynamic Voltage Management project, powered by DVI EDGE in conjunction with Landis+Gyr's Gridstream RF advanced metering network, to monitor and adjust distribution circuit voltage. This project will allow the utility to reduce voltage levels, targeting the most efficient band of the required voltage range, thereby conserving electricity.
"After recently completing our Gridstream advanced meter deployment, we've been investigating ways to extend the value of our smart grid systems. Voltage management has a number of benefits as both a way to increase energy efficiency and improve power quality," said Bruce Lovelin, chief engineer/systems engineering manager at Central Lincoln. "We look forward to demonstrating real energy and cost savings with this project."
While Central Lincoln's focus is on energy efficiency, the EDGE product can also provide Volt/VAR and Demand Response benefits. "The same CVR principles that provide precision voltage control to reduce overall energy usage can also be used to shave peak demand at the utility," said Phil Powell, DVI director of Innovation. "EDGE allows utilities to meet their specific objectives and makes the business case circuit-by-circuit."
