NASHVILLE, Tennessee, Oct. 9 (TNSsro) -- The Tennessee Public Utility Commission issued the following order (Docket No. 21-00083):
In Re: Audit Of Piedmont Natural Gas Company's Weather Normalization Adjustment For The Period October 1, 2020 Through April 30, 2021
ORDER ADOPTING WNA COMPLIANCE AUDIT REPORT OF TENNESSEE PUBLIC UTILITY COMMISSION'S UTILITIES DIVISION
This matter came before Chairman Kenneth C. Hill, Vice Chairman Herbert H. Hilliard, Commissioner Robin L. Morrison, Commissioner John Hie, and Commissioner David F. Jones of the Tennessee Public Utility Commission (the "Commission" or "TPUC"), the voting panel assigned to this docket, during a regularly scheduled Commission Conference held on September 20, 2021 to consider the report of the Commission's Utilities Division (the "Staff") resulting from the Staff's audit of Piedmont Natural Gas Company's ("Piedmont" or the "Company") Weather Normalization Adjustment ("WNA") for the year ended April 30, 2021. The WNA Audit Report (the "Report") is attached hereto as Exhibit 1 and incorporated by this reference.
The Company's WNA data was received for the period October 1, 2020 through April 30, 2021. The Staff completed its audit of the Company's filings on July 22, 2021 and filed its Report on July 23, 2021. The objective of the audit was to verify that the Company's calculations of the WNA adjustments were materially correct and that the Company has appropriately applied them to customers' bills during the period.
The WNA Audit Report contained one immaterial finding. The Company used an incorrect amount of the actual daily heating degree days for two days in the period (December 2020 and April 2021) to calculate the WNA factors. The error affected a total of thirty-four (34) bill cycles covering the period January 2021 and April 2021. This billing error resulted in a $34,962 undercollection in WNA revenues from Piedmont's customers./1
Due to the immateriality of the undercollection on a per customer basis, Staff recommended that the under-collection be added to Piedmont's Actual Cost Adjustment ("ACA") account balance in its next ACA audit filing with the Commission.
The Company agreed with the Staff's recommendation. Except for the finding noted in the Report, the Staff concluded that Piedmont appears to be correctly implementing the mechanics of its WNA Rider./2
During the regularly scheduled Commission Conference held on September 20, 2021, the voting panel considered the Staff's WNA Audit Report. The panel unanimously approved the July 23, 2021 WNA Audit Report as filed.
IT IS THEREFORE ORDERED THAT:
1. The Weather Normalization Adjustment Audit Report relative to Piedmont Natural Gas Company's costs for the year ended April 30, 2021, a copy of which is attached to this Order as Exhibit 1, is approved and adopted and the conclusions and recommendations contained therein are incorporated in this Order as if fully rewritten herein.
2. Piedmont Natural Gas Company shall include the under-collected amount in its next Actual Cost Adjustment filing with the Tennessee Public Utility Commission.
3. Any person who is aggrieved by the Commission's decision in this matter may file a Petition for Reconsideration with the Commission within fifteen (15) days from the date of this Order.
4. Any person who is aggrieved by the Commission's decision in this matter has the right to judicial review by filing a Petition for Review in the Tennessee Court of Appeals, Middle Section, within sixty (60) days from the date of this Order.
FOR THE TENNESSEE PUBLIC UTILITY COMMISSION:
Chairman Kenneth C. Hill,
Vice Chairman Herbert H. Hilliard,
Commissioner Robin L. Morrison,
Commissioner John Hie, and
