Sec. 6j.
(1) As used in this act:
(a) "Long-term firm gas transportation" means a binding agreement entered into between the electric utility and a natural gas transmission provider for a set period of time to provide firm delivery of natural gas to an electric generation facility.
(b) "Power supply cost recovery clause" means a clause in the electric rates or rate schedule of an electric utility that permits the monthly adjustment of rates for power supply to allow the utility to recover the booked costs, including transportation costs, reclamation costs, and disposal and reprocessing costs, of fuel burned by the utility for electric generation and the booked costs of purchased and net interchanged power transactions by the utility incurred under reasonable and prudent policies and practices.
(c) "Power supply cost recovery factor" means that element of the rates to be charged for electric service to reflect power supply costs incurred by an electric utility and made pursuant to a power supply cost recovery clause incorporated in the rates or rate schedule of an electric utility.
(2) The public service commission may incorporate a power supply cost recovery clause in the electric rates or rate schedule of an electric utility. Any order incorporating a power supply cost recovery clause shall be as a result of a hearing solely on the question of the inclusion of the clause in the rates or rate schedule. A hearing under this subsection shall be conducted as a contested case pursuant to chapter 4 of the administrative procedures act of 1969, 1969 PA 306, MCL 24.271 to 24.287, or, pursuant to subsection (18), as a result of a general rate case. Any order incorporating a power supply cost recovery clause shall replace and rescind any previous fuel cost adjustment clause or purchased and net interchanged power adjustment clause incorporated in the electric rates of the utility upon the effective date of the first power supply cost recovery factor authorized for the utility under its power supply cost recovery clause.
(3) In order to implement the power supply cost recovery clause established under subsection (2), an electric utility annually shall file, pursuant to procedures established by the commission, if any, a complete power supply cost recovery plan describing the expected sources of electric power supply and changes in the cost of power supply anticipated over a future 12-month period specified by the commission and requesting for each of those 12 months a specific power supply cost recovery factor. The utility shall file the plan not later than 3 months before the beginning of the 12-month period covered by the plan. The plan shall describe all major contracts and power supply arrangements entered into by the utility for providing power supply during the specified 12-month period. The description of the major contracts and arrangements shall include the price of fuel, the duration of the contract or arrangement, and an explanation or description of any other term or provision as required by the commission. For gas fuel supply contracts or arrangements, the description shall include whether the supply contracts or arrangements include long-term firm gas transportation and, if not, an explanation of how the utility proposes to ensure reliable and reasonably priced gas fuel supply to its generation facilities during the specified 12-month period. The plan shall also include the utility's evaluation of the reasonableness and prudence of its decisions to provide power supply in the manner described in the plan, in light of its existing sources of electrical generation, and an explanation of the actions taken by the utility to minimize the cost of fuel to the utility.
(4) In order to implement the power supply cost recovery clause established under subsection (2), a utility shall file, contemporaneously with the power supply cost recovery plan required by subsection (3), a 5-year forecast of the power supply requirements of its customers, its anticipated sources of supply, and projections of power supply costs, in light of its existing sources of electrical generation and sources of electrical generation under construction. The forecast shall include a description of all relevant major contracts and power supply arrangements entered into or contemplated by the utility, and any other information the commission may require.
(5) If an electric utility files a power supply cost recovery plan under subsection (3) and a 5-year forecast under subsection (4), the commission shall conduct a proceeding, to be known as a power supply and cost review, for the purpose of evaluating the reasonableness and prudence of the power supply cost recovery plan filed by a utility under subsection (3), and establishing the power supply cost recovery factors to implement a power supply cost recovery clause incorporated in the electric rates or rate schedule of the utility. The power supply and cost review shall be conducted as a contested case pursuant to chapter 4 of the administrative procedures act of 1969, 1969 PA 306, MCL 24.271 to 24.287.
(6) In its final order in a power supply and cost review, the commission shall evaluate the reasonableness and prudence of the decisions underlying the power supply cost recovery plan filed by an electric utility under subsection (3), and shall approve, disapprove, or amend the power supply cost recovery plan accordingly. In evaluating the decisions underlying the power supply cost recovery plan, the commission shall consider the cost and availability of the electrical generation available to the utility; the cost of short-term firm purchases available to the utility; the availability of interruptible service; the ability of the utility to reduce or to eliminate any firm sales to out-of-state customers if the utility is not a multi-state utility whose firm sales are subject to other regulatory authority; whether the utility has taken all appropriate actions to minimize the cost of fuel; and other relevant factors. The commission shall approve, reject, or amend the 12 monthly power supply cost recovery factors requested by the utility in its power supply cost recovery plan. The factors shall not reflect items the commission could reasonably anticipate would be disallowed under subsection (13). The factors ordered shall be described in fixed dollar amounts per unit of electricity, but may include specific amounts contingent on future events.
(7) In its final order in a power supply and cost review, the commission shall evaluate the decisions underlying the 5-year forecast filed by a utility under subsection (4). The commission may also indicate any cost items in the 5-year forecast that, on the basis of present evidence, the commission would be unlikely to permit the utility to recover from its customers in rates, rate schedules, or power supply cost recovery factors established in the future.
(8) The commission, on its own motion or the motion of any party, may make a finding and enter a temporary order granting approval or partial approval of a power supply cost recovery plan in a power supply and cost recovery review, after first giving notice to the parties to the review, and after giving the parties to the review a reasonable opportunity for a full and complete hearing. A temporary order made under this subsection is considered a final order for purposes of judicial review.
(9) If the commission has made a final or temporary order in a power supply and cost review, an electric utility may each month incorporate in its rates for the period covered by the order any amounts up to the power supply cost recovery factors permitted in that order. If the commission has not made a final or temporary order within 3 months after the submission of a complete power supply cost recovery plan, or by the beginning of the period covered in the plan, whichever comes later, or if a temporary order has expired without being extended or replaced, then pending an order that determines the power supply cost recovery factors, a utility may each month adjust its rates to incorporate all or a part of the power supply cost recovery factors requested in its plan. Any amounts collected under the power supply cost recovery factors before the commission makes its final order is subject to prompt refund with interest to the extent that the total amounts collected exceed the total amounts determined in the commission's final order to be reasonable and prudent for the same period of time.
(10) Not later than 3 months before the beginning of the third quarter of the 12-month period described in subsection (3), an electric utility may file a revised power supply cost recovery plan that covers the remainder of the 12-month period. Upon receipt of the revised power supply cost recovery plan, the commission shall reopen the power supply and cost review. In addition, the commission may reopen the power supply and cost review on its own motion or on the showing of good cause by any party if at least 6 months have elapsed since the utility submitted its complete filing and if there are at least 60 days remaining in the 12-month period under consideration. A reopened power supply and cost review shall be conducted as a contested case pursuant to chapter 4 of the administrative procedures act of 1969, 1969 PA 306, MCL 24.271 to 24.287, and in accordance with subsections (3), (6), (8), and (9).
(11) Not later than 45 days after the last day of each billing month in which a power supply cost recovery factor has been applied to customers' bills, an electric utility shall file with the commission a detailed statement for that month of the revenues recorded pursuant to the power supply cost recovery factor and the allowance for cost of power supply included in the base rates established in the latest commission order for the utility, and the cost of power supply. The detailed statement shall be in the manner and form prescribed by the commission. The commission shall establish procedures for insuring that the detailed statement is promptly verified and corrected if necessary.
(12) Not less than once a year, and not later than 3 months after the end of the 12-month period covered by an electric utility's power supply cost recovery plan, the commission shall commence a proceeding, to be known as a power supply cost reconciliation, as a contested case pursuant to chapter 4 of the administrative procedures act of 1969, 1969 PA 306, MCL 24.271 to 24.287. The commission shall permit reasonable discovery before and during the reconciliation proceeding in order to assist parties and interested persons in obtaining evidence concerning reconciliation issues including, but not limited to, the reasonableness and prudence of expenditures and the amounts collected pursuant to the clause. At the power supply cost reconciliation the commission shall reconcile the revenues recorded pursuant to the power supply cost recovery factors and the allowance for cost of power supply included in the base rates established in the latest commission order for the utility with the amounts actually expensed and included in the cost of power supply by the utility. The commission shall consider any issue regarding the reasonableness and prudence of expenses for which customers were charged if the issue was not considered adequately at a previously conducted power supply and cost review.
(13) In its order in a power supply cost reconciliation, the commission shall do all of the following:
(a) Disallow cost increases resulting from changes in accounting or rate-making expense treatment not previously approved by the commission. The commission may order the utility to pay a penalty of not more than 25% of the amount improperly collected. Costs incurred by the utility for penalty payments shall not be charged to customers.
(b) Not disallow the capacity charges for any facilities for which the electric utility would otherwise have a purchase obligation if the commission has approved capacity charges in a contract with a qualifying facility, as that term is defined by the Federal Energy Regulatory Commission pursuant to the public utilities regulatory policies act of 1978, Public Law 95-617, 92 Stat 3117, unless the commission has ordered revised capacity charges upon reconsideration under this subsection. A contract is valid and binding in accordance with its terms, and capacity charges paid pursuant to that contract are recoverable costs of the utility for rate-making purposes notwithstanding that the order approving that contract is later vacated, modified, or otherwise held to be invalid in whole or in part if the order approving the contract has not been stayed or suspended by a competent court within 30 days after the date of the order, or by July 29, 1987 if the order was issued after September 1, 1986 and before June 29, 1987. The commission shall determine the scope and manner of the review of capacity charges for a qualifying facility. Except as to approvals for qualifying facilities granted by the commission before June 1, 1987, proceedings before the commission seeking those approvals shall be conducted as a contested case pursuant to chapter 4 of the administrative procedures act of 1969, 1969 PA 306, MCL 24.271 to 24.287. The commission, upon its own motion or upon application of any person, may reconsider its approval of capacity charges for a qualifying facility in a contested case hearing after passage of a period necessary for financing the qualifying facility, if both of the following apply:
(i) The commission has first issued an order making a finding based on evidence presented in a contested case that there has been a substantial change in circumstances since the commission's initial approval.
(ii) The commission finding is set forth in a commission order subject to immediate judicial review.
The financing period for a qualifying facility during which previously approved capacity charges are not subject to commission reconsideration is 17.5 years, beginning with the date of commercial operation, for all qualifying facilities, except that the minimum financing period before reconsideration of the previously approved capacity charges is for the duration of the financing for a qualifying facility that produces electric energy by the use of biomass, waste, wood, hydroelectric, wind, and other renewable resources, or any combination of renewable resources, as the primary energy source.
(c) Disallow net increased costs attributable to a generating plant outage of more than 90 days in duration unless the utility demonstrates by clear and satisfactory evidence that the outage, or any part of the outage, was not caused or prolonged by the utility's negligence or by unreasonable or imprudent management.
(d) Disallow transportation costs attributable to capital investments to develop a utility's capability to transport fuel or relocate fuel at the utility's facilities and disallow unloading and handling expenses incurred after receipt of fuel by the utility.
(e) Disallow the cost of fuel purchased from an affiliated company to the extent that the fuel is more costly than fuel of requisite quality available at or about the same time from other suppliers with whom it would be comparably cost beneficial to deal.
(f) Disallow charges unreasonably or imprudently incurred for fuel not taken.
(g) Disallow additional costs resulting from unreasonably or imprudently renegotiated fuel contracts.
(h) Disallow penalty charges unreasonably or imprudently incurred.
(i) Disallow demurrage charges.
(j) Disallow increases in charges for nuclear fuel disposal unless the utility has received the prior approval of the commission.
(14) In its order in a power supply cost reconciliation, the commission shall require an electric utility to refund to customers or credit to customers' bills any net amount determined to have been recovered over the period covered in excess of the amounts determined to have been actually expensed by the utility for power supply, and to have been incurred through reasonable and prudent actions not precluded by the commission order in the power supply and cost review. The commission shall apportion the refunds or credits among the customers of the utility utilizing procedures that the commission determines to be reasonable. The commission may adopt different procedures with respect to customers served under the various rate schedules of the utility and may, in appropriate circumstances, order refunds or credits in proportion to the excess amounts actually collected from each such customer during the period covered.
(15) In its order in a power supply cost reconciliation, the commission shall authorize an electric utility to recover from customers any net amount by which the amount determined to have been recovered over the period covered was less than the amount determined to have been actually expensed by the utility for power supply, and to have been incurred through reasonable and prudent actions not precluded by the commission order in the power supply and cost review. For excess costs incurred through management actions contrary to the commission's power supply and cost review order, the commission shall authorize a utility to recover costs incurred for power supply in the reconciliation period in excess of the amount recovered over the period only if the utility demonstrates by clear and convincing evidence that the excess expenses were beyond the ability of the utility to control through reasonable and prudent actions. For excess costs incurred through management actions consistent with the commission's power supply and cost review order, the commission shall authorize a utility to recover costs incurred for power supply in the reconciliation period in excess of the amount recovered over the period only if the utility demonstrates that the level of those expenses resulted from reasonable and prudent management actions. The amounts in excess of the amounts actually recovered by the utility for power supply shall be apportioned among and charged to the customers of the utility utilizing procedures that the commission determines to be reasonable. The commission may adopt different procedures with respect to customers served under the various rate schedules of the utility and may, in appropriate circumstances, order charges to be made in proportion to the amounts that would have been paid by those customers if the amounts in excess of the amounts actually recovered by the utility for cost of power supply had been included in the power supply cost recovery factors with respect to those customers during the period covered. Charges for the excess amounts shall be spread over a period that the commission determines to be appropriate.
(16) If the commission orders refunds or credits under subsection (14), or additional charges to customers under subsection (15), in its final order in a power supply cost reconciliation, the refunds, credits, or additional charges shall include interest. In determining the interest included in a refund, credit, or additional charge under this subsection, the commission shall consider, to the extent material and practicable, the time at which the excess recoveries or insufficient recoveries, or both occurred. The commission shall determine a rate of interest for excess recoveries, refunds, and credits equal to the greater of the average short-term borrowing rate available to the utility during the appropriate period, or the authorized rate of return on the common stock of the utility during that same period. Costs incurred by the utility for refunds and interest on refunds shall not be charged to customers. The commission shall determine a rate of interest for insufficient recoveries and additional charges equal to the average short-term borrowing rate available to the utility during the appropriate period.
(17) To avoid undue hardship or unduly burdensome or excessive cost, the commission may do both of the following:
(a) Exempt an electric utility with fewer than 200,000 customers in this state from 1 or more of the procedural provisions of this section or may modify the filing requirements of this section.
(b) Exempt an energy utility organized as a cooperative corporation under sections 98 to 109 of 1931 PA 327, MCL 450.98 to 450.109, from 1 or more of the provisions of this section.
(18) Notwithstanding any other provision of this act, the commission may, upon application by an electric utility, set power supply cost recovery factors, in a manner otherwise consistent with this act, in an order resulting from a general rate case. By October 27, 1987, for the purpose of setting power supply cost recovery factors, the commission shall permit an electric utility to reopen a general rate case in which a final order was issued within 120 days before or after June 29, 1987 or to amend an application or reopen the evidentiary record in a pending general rate case. If the commission sets power supply cost recovery factors in an order resulting from a general rate case, all of the following apply:
(a) The power supply cost recovery factors shall cover a future period of 48 months or the number of months that elapse until the commission orders new power supply cost recovery factors in a general rate case, whichever is the shorter period.
(b) The commission shall conduct annual reconciliation proceedings under subsection (12) and if an annual reconciliation proceeding shows a recoverable amount under subsection (15), the commission shall authorize the electric utility to defer the amount and to accumulate interest on the amount under subsection (16), and in the next order resulting from a general rate case authorize the utility to recover the amount and interest from its customers in the manner provided in subsection (15).
(c) The power supply cost recovery factors are not subject to revision under subsection (10).
