True-up " Not Later than June 1 of each year, Transmission provider will calculate and post to its OASIS the
actual Summed Reactive billing Loads on the Transmission System during each month of the preceding calendar
year and the difference between that actual amount and the previously projected amount for the same calendar year.
If the Aggregate annual Reactive Revenue Requirement has changed during that calendar year pursuant to a Section
205 or 206 rate change accepted by FERC, the actual and differential load information will be broken out by the
period(s) before and after the effective date(s) of such change. From such calculations, the Transmission Provider
will calculate a true-up adjustment designed to reverse any under-collection or over-collection of the revenue
requirements identified in Section 2 and 3. The true-up adjustment and related calculations shall be posted to the
Transmission Provider's OASIS no later than June 1."

" Interest on any over-recovery of the revenue requirements shall be determined based on FERC's regulations
at 18 C.F.R. 35.19a. Interest on any under-recovery of the net revenue requirement shall be determined using
the interest rate equal to Black Hills Power's actual short-term debt costs capped at the applicable FERC refund
interest rate. In either case, the interest payable shall be calculated as follows. The interest rate will be
determined using the applicable rate averaged across the sixteen (16) months, January of the year prior through
the April of the year in which the true-up occurs. That interest rate will be applied, with quarterly compounding, to the
principal amount (i.e., the over or under recovery in the net revenue requirement) for the eighteen (18) months during
which that over or under recovery exists."
