As part of the Northwest Energy Efficiency Alliance’s (NEEA’s) Distribution Efficiency Initiative, SAIC studied utility and customer benefits to estimate the potential savings achieved from automating the control of the distribution system voltage within industry standards.
SAIC provided project management, system planning, concept design, and data collection and analysis for more than 400 customer locations and 31 distribution feeders for 13 Northwest electric utilities. Voltage optimization techniques were implemented through a series of applications for end-use metering and through distribution feeder projects at six of the electric facilities.
SAIC’s study revealed that, on average, energy and demand can be reduced by 2 percent annually by performing system improvements and optimizing voltage levels. Overall, the study showed that with cost-effective application of distribution system efficiency, greater voltage optimization savings are possible.
