RE: Monthly Deferred Cost Report

Attached is the PGA monthly report of activity in the Gas Deferral Accounts for the month of
September 2023. This information is submitted in compliance with Order Number 35581 issued
in the Company’s Purchase Gas Cost Adjustment filing (Case No. AVU-G-22-06). This report is
being filed in electronic format only per approval from the filing center.

For the month, commodity costs were lower than the embedded PGA commodity WACOG,
resulting in a rebate deferral in the amount of $425,251. Demand costs were higher than the PGA
demand WACOG resulting in a surcharge deferral in the amount of $438,679. The cumulative
balance in the deferral account (including both commodity and demand) is a surcharge of
$26,106,756 (including interest). The amount of amortization recorded for the month is $387,709
for a total rebate balance of $812,422 (including interest).

Per Order No. 35581, the Company has included a confidential Quarterly Commodity WACOG
Forecast update in this PGA Monthly Activity Report as Attachment A for the period October
2023– September 2024. In accordance with Case No. GNR-U-20-01, Order No. 34602, which
suspends the requirement to file physical copies, it will be sent electronically with the monthly
deferral report.

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,
