Pro Forma Transmission Expenses/Revenue($000s)
(2) After the completion of the Company's revenue requirement in this case, it was determined the change in transmission revenues in Pro Forma Transmission Revenues and
Expenses Adjustment 3.00T included in Ms. Andrews' Exhibit No. 5, Schedule 1, was in error. The Company will correct this error during the process of this case. Correcting this
error increases transmission revenues $25,000 and decreases the Company's requested revenue requirement $26,000. This correction has no impact on the Company's proposed
Power Cost Adjustment base.
(1) Rate Year 1 effective September 1, 2021 through August 31, 2022 was used for transmission expenses and revenues over the Two-Year Rate Plan as amounts will be known by
the new rate effective date September 1, 2021. Changes in expense shown above from Rate Year 1 Pro Forma as compared to Rate Year 2 Pro Forma are not material.
