Sec. 6.5. Absent fraud, concealment, or gross mismanagement, a utility shall recover through rates the actual costs the utility has incurred in reliance on a certificate issued under this chapter, and as modified under sections 5.5 and 6 of this chapter as follows:

(1) If a facility has been found to be completed and the facility’s construction has been subject to ongoing review under section 6(a) of this chapter, the costs of construction approved by the commission during the ongoing review shall be included in the utility’s rate base without further commission review.

(2) If a facility has been found to be completed and the facility’s construction is subject to subsequent review under section 6(d) of this chapter, the costs of construction that do not exceed the estimate found under section 5(b)(1) of this chapter shall be included in the utility’s rate base, except for costs that are shown to result from inadequate quality controls. However, inclusion of costs in excess of the estimate found by the commission under section 5(b)(1) of this chapter in the utility’s rate base is not permitted unless shown by the utility in construction of that facility to be necessary and prudent.

(3) If a facility has been canceled as a result of the modification or revocation of the certificate under section 5.5 or 6 of this chapter and the facility’s construction has been subject to ongoing review under section 6(a) of this chapter (including reviews after cancellation), the costs of construction approved by the commission during the review shall be recovered by the utility by inclusion in rates and amortization over a reasonable time to be determined by the commission. The utility shall be permitted to earn a return, computed using the utility’s authorized rate of return, on the unamortized balance.

(4) If a facility has been canceled as a result of the modification or revocation of the certificate under section 5.5 or 6 of this chapter and the facility’s construction is subject to subsequent review under section 6(d) of this chapter, the costs of construction incurred before cancellation that were included in the estimate found under section 5(b)(1) of this chapter and that have not been shown to result from inadequate quality controls shall be recovered by the utility by inclusion in rates and amortization over a reasonable time to be determined by the commission. The utility shall be permitted to earn a return, computed using the utility’s authorized rate of return, on the unamortized balance. However, costs that were not included in the estimate found by the commission under section 5(b)(1) of this chapter may not be included in rates unless shown by the utility in construction of that facility to be necessary and prudent.
