Working on a Duke Energy account in Raleigh. Customer has primary service delivery but secondary metering through CTs. Duke says no primary discount because metering is secondary side. This doesn't sound right to me. Anyone know Duke's actual policy?
Duke Energy Carolinas - Primary vs Secondary metering confusion
Duke's tariff is based on delivery voltage not metering configuration. If they're receiving primary voltage (4kV-35kV range typically) they should get the discount regardless of where the meter sits. File a complaint with the NCUC if Duke won't budge.
I had same issue in Jacksonville with JEA. Metering location doesn't matter - it's service delivery voltage. Duke should follow their Schedule P tariff. The discount is usually 5-8% depending on actual voltage level.
Update: Took it up the chain at Duke. Turns out the CSR was wrong. Got confirmation that primary discount applies based on delivery voltage. Retroactive billing adjustment of $4,200 for past 18 months.
