RE: Monthly Deferred Cost Report

Attached is the PGA monthly report of activity in the Gas Deferral Accounts for the month of July
2022. 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 lower than the embedded PGA commodity WACOG,
resulting in a rebate deferral in the amount of $551,413. Demand costs were higher than the PGA
demand WACOG, resulting in a surcharge deferral in the amount of $541,206. The cumulative
balance in the deferral account (including both commodity and demand) is a surcharge of
$9,439,095 (including interest). The amount of amortization recorded for the month is $29,212 for
a total surcharge balance of $3,250,937 (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,
