(1) (a) Whenever there is filed with the commission any tariff or schedule stating any new or changed individual or joint rate, fare, toll, rental, charge, classification, contract, practice, rule, or regulation, the commission has power, either upon complaint or upon its own initiative and without complaint, at once, and, if it so orders, without answer or other formal pleadings by the interested public utilities, but upon reasonable notice, to have a hearing concerning the propriety of such rate, fare, toll, rental, charge, classification, contract, practice, rule, or regulation if it believes that such a hearing is required and that such rate, fare, toll, rental, charge, classification, contract, practice, rule, or regulation may be improper.
Pending the hearing and decision on the hearing, in the case of a public utility otherthan a rail carrier, the rate, fare, toll, rental, charge, classification, contract, practice, rule, or regulation must not go into effect; but the period of suspension of the rate, fare, toll, rental, charge, classification, contract, practice, rule, or regulation must not extend beyond one hundred twenty days beyond the time when the rate, fare, toll, rental, charge, classification, contract, practice, rule, or regulation would otherwise go into effect unless the commission, in its discretion, and by separate order, extends the period of suspension for a further period not exceeding one hundred thirty days.
Repealed.
Notwithstanding any order of suspension of a proposed increase in electric, gas, orsteam rates under this subsection (1), after January 1, 2012, the commission may order, without hearing, interim rates, at any level up to the proposed new rates, to take effect not later than sixty days after the filing for the proposed rate increase. In making a determination as to whether to allow interim rates, the commission shall consider the amount of the revenue deficiency presented by the utility and the extent to which this deficiency would adversely affect the utility during the time period required to hold hearings on the suspended rates.
(2) (a) (I) If a hearing is held thereon, whether completed before or after the expiration of the period of suspension, the commission shall establish the rates, fares, tolls, rentals, charges, classifications, contracts, practices, or rules proposed, in whole or in part, or others in lieu thereof, that it finds just and reasonable. In making such finding in the case of a public utility other than a rail carrier, the commission may consider current, future, or past test periods or any reasonable combination thereof and any other factors that may affect the sufficiency or insufficiency of such rates, fares, tolls, rentals, charges, or classifications during the period the same may be in effect and may consider any factors that influence an adequate supply of energy, encourage energy conservation, or encourage renewable energy development. The commission shall consider the reasonableness of the test period revenue requirements presented by the utility.
If the rates established by the commission after hearing are lower than any interimrates established under paragraph (d) of subsection (1) of this section, then the commission shall order the utility to return to customers on their utility bills through a negative rate rider the difference between the total amount that would have been collected under the final approved rates and the amount collected under the interim rates for the period that the interim rates were in effect, with interest at a rate established by the commission.
All such rates, fares, tolls, rentals, charges, classifications, contracts, practices, orrules not so suspended, on the effective date thereof, which, in the case of a public utility other than a rail carrier, shall not be less than thirty days after the time of filing the same with the commission, or of such lesser time as the commission may grant, shall go into effect and be the established and effective rates, fares, tolls, rentals, charges, classifications, contracts, practices, and rules subject to the power of the commission, after a hearing on its own motion or upon complaint, as provided in this article, to alter or modify the same.
Repealed.
If the commission considers factors which encourage renewable energy development,it shall also make findings and give due consideration to the effect of such factors on the utility's ability to recover its capital and operating costs.
The tariffs and schedules required by this title shall contain such information, andshall be published, filed, and posted in such form and manner, as the commission by regulation shall prescribe; and the commission is authorized to reject any tariff or schedule filed with it which is not in the form required by this section and by such regulations. Any tariff or schedule so rejected by the commission shall be void and its use shall be unlawful.
(a) The provisions of this section relating to suspension of rates, fares, tolls, rentals, charges, classifications, contracts, practices, rules, or regulations pending the hearing and decision thereon shall not apply to cooperative electric associations, but this subsection (4) shall not be construed to exempt such associations from any other provision of this section. Notwithstanding any other provision of law, no cooperative electric association shall establish, charge, or collect a discriminatory or preferential rate, charge, rule, or regulation which would be violative of section 40-3-106 (1) or section 40-3-111. Upon complaint filed by any member or customer of a cooperative electric association or by any affected public utility, the commission shall determine whether the rate, charge, rule, or regulation in question is contrary to this section, section 40-3-106 (1), or section 40-3-111.
(b) (I) Paragraph (a) of this subsection (4) shall not be applicable to a cooperative electric association which has voted to exempt itself from regulation pursuant to the provisions of section 40-9.5-103. Regulation of such cooperative electric associations shall be in the manner provided in article 9.5 of this title.
(II) Repealed.
(c) and (c.1) Repealed.
