Aeolus-to-Bridger/Anticlinetransmission project.
Column F is the gross revenue requirement from file "Energy Gateway GM 2017
03 13 21%US Tax.xlsm"Generic tab row 1711.
The Company expects to recover 12 percent revenue requirement in column F
from wholesale transmission customers under the Company's Open Access
Transmission Tariff (OATT)formula rate.
Column I is the difference between columns F and G,and represents the amount
the Company expects to recover from retail customers.

for the Aeolus to Bridger/Anticlinetransmission project.
Column O is the real levelized revenue requirement for the transmission project.
The real levelized revenue requirement is a stream of annual payments increasing
with inflation having the same present value as the nominal revenue requirements
in column F.
