Focus on grid-interactive electric water heaters for Peak Load Management Alliance


Vallejo, CA, U.S.A. — (METERING.COM) — August 16, 2013 – A Grid-Interactive Water Heating Interest Group (GIWH-IG) is to be formed by the Peak Load Management Alliance (PLMA), under the leadership of Gary Connett, director of Demand Side Management and Member Services for Great River Energy, in a move to advance the use of this technology in the market.

Grid-interactive water heating is the emerging consensus term describing high speed, two-way communication between the electric water heating appliance and the electric utility, balancing authority, independent system operator, or aggregation entity. When equipped with a grid-interactive control, a large capacity, electric thermal storage water heater becomes a “battery” for storing electric energy and has the ability to follow locational marginal prices, better integrate renewable energy, and provide fast regulation service.

“The benefits of this important technology aren’t well understood, as evidenced by recent Department of Energy efforts to restrict or ban large capacity electric resistance water heaters,” said Connett. “This group will show that electric resistance water heaters can be a very useful tool to optimize energy use and increase efficiency in the home and on the electric grid.”

The new interest group will provide a focused platform for information sharing and market development efforts in order to move grid-interactive water heating technologies from pilot project to market.
