Electric utility groups are applauding the Energy Department’s (DOE) decision to reconsider a rule it issued last year that would limit the size of residential water heaters manufactured after April 2015.
In April 2010, the DOE Office of Energy Efficiency issued a final rule on energy conservation standards for residential water heaters. Electric utility groups feared the rule would interfere with demand-response programs in which consumers allow their utilities to control their water heater’s cycling based on grid conditions.
On June 6, DOE issued a request for information seeking comments on how the rule would affect utility programs that use high-storage-volume (above 55 gallons) electric storage water heaters to reduce peak electricity demand.
The American Public Power Association (APPA) , National Rural Electric Cooperative Association (NRECA) , PJM Interconnection and the Steffes Corp. issued a statement June 12 applauding the DOE’s move to request more information on this issue.
“APPA is pleased that the Department of Energy has taken this important first step toward relieving the 2010 constraints imposed on electric water heaters in utility demand-response programs,” said President and CEO Mark Crisson. “Large-volume electric water heaters provide an environmentally friendly and cost effective means for utilities to improve overall system efficiency.”
NRECA CEO Glenn English concurred, noting that electric co-ops have relied on the energy storage capacity of residential water heaters to help manage demand on their distribution systems.
DOE will accept comments through July 13. Information on submitting comments can be found in the RFI. APPA encourages its members that have water heater programs to submit information. Read more.
