RE: Monthly Deferred Cost Report
Attached is the PGA monthly report of activity in the Gas Deferral Accounts for the month of
November 2021. This information is submitted in compliance with Order Number 35151 issued
in the Company’s Purchase Gas Cost Adjustment filing (Case No. AVU-G-21-04). This report is
being filed in electronic format only per approval from the filing center.
For the month, commodity costs were higher than the embedded PGA commodity WACOG,
resulting in a surcharge deferral in the amount of $1,476,924. Demand costs were lower than the
PGA demand WACOG, resulting in a rebate deferral in the amount of $229,203. The cumulative
balance in the deferral account (including both commodity and demand) is a surcharge of
$3,497,658 (including interest). The amount of amortization recorded for the month is $151,065
for a total surcharge balance of $4,339,011 (including interest).
If you have any questions regarding this information, please feel free to contact Marcus Garbarino
via email at [e-mail] or via telephone at [phone]. Thank you!
Sincerely,
