Smart Grid Application: Voltage ConservationSmart Grid Application: Voltage ConservationPrecision Voltage ControlPrecision Voltage Control
• Application enabled by Smart Grid Technology
U t lt f db k f t t (AMI)• Uses customer voltage feedback from smart meters (AMI)
• Controls voltage to a more precise level
• Results in 4% reduction in off‐peak kWhs
• Improved Delivery of Electricity

Dominion Voltage Conservation Business CaseDominion Voltage Conservation Business CaseRequires No Change in Customer Behaviorq g
• Trabue test results confirm full deployment savings of 2.34 million
MWH per year or 2.79% of the total system load
• Based on Trabue tests, system level energy savings to customers
$from Voltage Conservation is projected at $1.7 billion over 15 years
• $1,682B in avoided purchase power costs
• Total Cost of AMI installation $600M
