Business Drivers‣ Snohomish CVR 2006:‣ Robert Fletcher of Snohomish PUD said conservationvoltage reduction drops the utility's voltage by 2.5 percent, to117V.‣ "That buys the average customer about 350-400 kWh peryear savings," Fletcher said. "So the net savings for ourcustomers is about $3.5 million a year.“‣ Northwest Energy Efficiency Alliance DistributionEfficiency Initiative:‣ 13 Northwest utilities consolidating research efforts validatevalue of conservation voltage reduction‣ Results from “The NEEA Phase 1 DEI Final Report” showsthat "operating a utility distribution system in the lower half ofthe acceptable voltage range (120-114 volts) saves energy,reduces demand, and reduces reactive power requirementswithout negatively impacting the customer.‣ Validated energy savings results of 1 to 3 percent totalenergy reduction, 2 to 4 percent reduction in kW demand,and a 4 to 10 percent reduction in kvar demand.”10
