Margin Decoupling Tracker

The North Carolina Utilities Commission gave Piedmont authorization in November 2005 to implement a decoupling mechanism, now called the Margin Decoupling Tracker. The Margin Decoupling Tracker protects customers from the potential over-recovery of margin by the Company and protects the Company from potential under-recovery of margin. It tracks margin recovery from residential customers (Rate 101) and small/medium service customers (Rates 102 and 152) on a monthly basis. Under this mechanism, the Company makes semi-annual adjustments, in April and November of each year, to the residential and small/medium service usage rates in order to refund or recover differences from the Commission-approved margin level.
