Current through Register Vol. 47, No. 3, July 24, 2024
(1)
Time
				period for updates for subsequent proceeding.
The utility shall file
				within 90 days of the end of the verification period the information, exhibits,
				and workpapers described in subrule 26.6(2).
(2)
Updated information
				required.
The filing required in subrule 26.6(1) shall include an
				update of the cost-of-service study, revenue allocation, resulting rates, and
				revenue verifications, based upon methodologies approved by the commission in
				the general rate proceeding, with actual costs, revenues, and sales applicable
				during the verification period. The filing shall include a calculation of the
				utility's return on equity based upon the updated information, exhibits, and
				workpapers.
(3)
Other
				parties' filing requirements.
Any party to the future test year rate
				proceeding, or any other party who is granted intervention in the subsequent
				proceeding, may file a response to the return on equity calculation, and other
				information, exhibits, and workpapers, filed by the utility with information,
				exhibits, and workpapers within 30 days of the date the utility files its
				information, exhibits, and workpapers.
(4)
Commission order
				required.
The commission shall issue within 30 days of the filing of
				any response, or, if no response is filed, within 60 days of the utility's
				filing, an order which finds that the actual costs and revenues are reasonably
				consistent with the costs and revenues approved by the commission or shall set
				the matter for hearing to address questions from the commission. If the
				commission determines that the actual return on equity of the utility during
				the verification period falls within a standard of reasonableness of 50 basis
				points above or 50 basis points below the return on equity approved by the
				commission, the actual costs and revenues shall be presumed to be reasonably
				consistent with the costs and revenues approved by the commission.
(5)
Hearing to be scheduled.
If the commission determines that the return on equity based upon actual costs
				and revenues does not fall within the standard of reasonableness in subrule
				26.6(4) or the commission has questions about any of the information, exhibits,
				and workpapers filed by the utility, the commission shall schedule the review
				of the actual costs and revenues for hearing. The hearing date of the
				subsequent proceeding shall be set no more than 90 days from the date the
				utility files its information, exhibits, and workpapers, unless otherwise
				ordered by the commission. The issues to be considered at the hearing are the
				review of any inconsistencies between actual costs and revenues compared to the
				costs and revenues approved by the commission. The utility and other parties
				shall provide witnesses to respond to commission questions at the hearing and
				parties may ask questions of the witnesses.
(6)
Order addressing issues in
				subsequent proceeding.
The commission shall issue a final order within
				120 days of the filing of the utility's information, exhibits, and workpapers
				required in subrule 26.6(2), unless otherwise ordered by the commission. In the
				order, the commission will determine whether the actual costs and revenues are
				reasonably consistent with the costs and revenues approved by the commission
				and whether there should be any adjustment in rates based upon the commission's
				determination. Any increase or reduction in rates based upon a return on equity
				outside of the standard of reasonableness band shall be calculated in relation
				to the band and not the return on equity approved by the commission.
