Mo. Code Regs. tit. 20 § 4240-20.091
Current through Register Vol. 49, No. 21, November 1, 2024.
Section 20 CSR 4240-20.091 - Electric Utility Environmental Cost Recovery MechanismsPURPOSE: This rule allows the establishment of an Environmental Cost Recovery Mechanism, which allows periodic rate adjustments to reflect net increases or decreases in an electric utility's prudently incurred costs directly related to compliance with any federal, state, or local environmental law, regulation, or rule.
(1) Definitions. As used in this rule, the following terms mean as follows: (A) Electric utility means electrical corporation as defined in section 386.020, RSMo, subject to commission regulation pursuant to Chapters 386 and 393, RSMo;(B) Environmental Cost Recovery Mechanism (ECRM) means a mechanism established in a general rate proceeding that allows periodic rate adjustments, outside a general rate proceeding, to reflect the net increases or decreases in an electric utility's incurred environmental costs;(C) Environmental costs means prudently incurred costs, both capital and expense, directly related to compliance with any federal, state, or local environmental law, regulation, or rule. 1. Environmental costs do not include fuel and purchased power costs as defined in 4 CSR 240-20.090(1)(B).2. Prudently incurred costs do not include any increased costs resulting from negligent or wrongful acts or omissions by the utility;(D) The environmental revenue requirement shall be comprised of the following: 1. All expensed environmental costs (other than taxes and depreciation associated with capital projects) that are included in the electric utility's revenue requirement in the general rate proceeding in which the ECRM is established; and2. The costs (i.e., the return, taxes, and depreciation) of any major capital projects whose primary purpose is to permit the electric utility to comply with any federal, state, or local environmental law, regulation, or rule. Representative examples of such capital projects to be included (as of the date of adoption of this rule) are electrostatic precipitators, fabric filters, nitrous oxide emissions control equipment, and flue gas desulfurization equipment. The costs of such capital projects shall be those identified on the electric utility's books and records as of the last day of the test year, as updated, utilized in the general rate proceeding in which the ECRM is established;(E) General rate proceeding means a general rate increase proceeding or complaint proceeding before the commission in which all relevant factors that may affect the costs, or rates and charges, of the electric utility are considered by the commission;(F) Rate class is a customer class as defined in an electric utility's tariff. Generally, rate classes include Residential, Small General Service, Large General Service, and Large Power Service, but may include additional rate classes. Each rate class includes all customers served under all variations of the rate schedules available to that class;(G) Staff means the staff of the Public Service Commission; and(H) True-up year means the twelve (12)-month period beginning on the first day of the first calendar month following the effective date of the commission order approving an ECRM unless the effective date is on the first day of the calendar month. If the effective date of the commission order approving a rate mechanism is on the first day of a calendar month, then the true-up year begins on the effective date of the commission order. The first annual true-up period shall end on the last day of the twelfth calendar month following the effective date of the commission order establishing the ECRM. Subsequent true-up years shall be the succeeding twelve (12)-month periods. If a general rate proceeding is concluded prior to the conclusion of a true-up year, the true-up year may be less than twelve (12) months. If the commission approves both a fuel adjustment clause mechanism and an ECRM for the electric utility, the true-up year will be the same for both.(2) Applications to Establish, Continue, or Modify an ECRM. Pursuant to the provisions of this rule, 4 CSR 240-2.060, and section 386.266, RSMo, only an electric utility in a general rate proceeding may file an application with the commission to establish, continue, or modify an ECRM by filing tariff schedules. Any party in a general rate proceeding in which an ECRM is in effect or proposed may seek to continue, modify, or oppose the ECRM. The commission shall approve, modify, or reject such applications to establish an ECRM only after providing the opportunity for a full hearing in a general rate proceeding. The commission shall consider all relevant factors that may affect the costs or overall rates and charges of the petitioning electric utility. (A) The commission may approve the establishment, continuation, or modification of an ECRM and rate schedules implementing an ECRM provided that it finds that the ECRM it approves is reasonably designed to provide the electric utility with a sufficient opportunity to earn a fair return on equity. Any rate schedule approved to implement an ECRM must conform to the ECRM approved by the commission.(B) The commission may take into account any change in business risk to the utility resulting from establishment, continuation, or modification of the ECRM in setting the electric utility's allowed return in any rate proceeding, in addition to any other changes in business risk experienced by the electric utility.(C) In determining which environmental cost components to include in an ECRM, the commission will consider, but is not limited to only considering, the magnitude of the costs, the ability of the utility to manage the costs, the incentive provided to the utility as a result of the inclusion or exclusion of the cost, and the extent to which the cost is related to environmental compliance.(D) The commission may, in its discretion, determine what portion of prudently incurred environmental costs may be recovered in an ECRM and what portion shall be recovered in base rates.(E) Any party to the general rate proceeding may oppose the establishment, continuation, or modification of an ECRM and/or may propose alternative ECRMs for the commission's consideration, including but not limited to modifications to the electric utility's proposed ECRM.(F) The ECRM shall be based on known and measurable environmental costs that have been incurred by the electric utility.(G) If an ECRM is approved, the commission shall determine the base environmental revenue requirement.(H) If costs are requested to be recovered through the ECRM and the revenue to be collected in the ECRM rate schedules exceeds two and one-half percent (2.5%) of the electric utility's Missouri annual gross jurisdictional revenues, the electric utility cannot subsequently request that any cost identified as an environmental cost be recovered through a fuel rate adjustment mechanism.(I) The electric utility shall include in its initial notice to customers regarding the general rate case, a commission approved description of how the costs passed through the proposed ECRM requested shall be applied to monthly bills.(J) The electric utility shall meet the filing requirements in 4 CSR 240-3.162(2), in conjunction with an application to establish an ECRM, and 4 CSR 240-3.162(3), in conjunction with an application to continue or modify an ECRM.(3) Application for Discontinuation of an ECRM. The commission shall allow or require the rate schedules that define and implement an ECRM to be discontinued and withdrawn only after providing the opportunity for a full hearing in a general rate proceeding. The commission shall consider all relevant factors that affect the cost or overall rates and charges of the petitioning electric utility. (A) Any party to the general rate proceeding may oppose the discontinuation of an ECRM on the grounds that the electric utility is currently experiencing, or in the next four (4) years is likely to experience, declining costs or on any other grounds that would result in a detriment to the public interest. If the commission finds that the electric utility is seeking to discontinue the ECRM under these circumstances, the commission shall not permit the ECRM to be discontinued, and shall order its continuation or modification. To continue or modify the ECRM under such circumstances, the commission must find that it provides the electric utility with a sufficient opportunity to earn a fair rate of return on equity.(B) The commission may take into account any change in business risk to the corporation resulting from discontinuance of the ECRM in setting the electric utility's allowed return in any rate proceeding, in addition to any other changes in business risk experienced by the electric utility.(C) The electric utility shall include, in its initial notice to customers regarding the general rate case, a commission approved description of why it believes the ECRM should be discontinued.(D) Subsections (2)(C) through (2)(H) shall apply to any proposal for continuation or modification.(E) The electric utility shall meet the filing requirements in 4 CSR 240-3.162(4).(4) Periodic Adjustments of ECRMs. If an electric utility files proposed rate schedules to adjust its ECRM rates between general rate proceedings, the staff shall examine and analyze the information filed by the electric utility in accordance with 4 CSR 240-3.162 and additional information obtained through discovery, if any, to determine if the proposed adjustment to the ECRM is in accordance with the provisions of this rule, section 386.266, RSMo, and the ECRM established in the most recent general rate proceeding. The staff shall submit a recommendation regarding its examination and analysis to the commission not later than thirty (30) days after the electric utility files its tariff schedules to adjust its ECRM rates. If the ECRM rate adjustment is in accordance with the provisions of this rule, section 386.266, RSMo, and the ECRM established in the most recent general rate proceeding, the commission shall either issue an interim rate adjustment order approving the tariff schedules and the ECRM rate adjustments within sixty (60) days of the electric utility's filing or, if no such order is issued, the tariff schedules and the ECRM rate adjustments shall take effect sixty (60) days after the tariff schedules were filed. If the ECRM rate adjustment is not in accordance with the provisions of this rule, section 386.266, RSMo, or the ECRM established in the most recent rate proceeding, the commission shall reject the proposed rate schedules within sixty (60) days of the electric utility's filing and may instead order implementation of an appropriate interim rate schedule(s). (A) The periodic adjustments shall be limited to the expense items and the capital projects that are used to determine the environmental revenue requirement in the previous general rate proceeding and those investments or expenses necessary to comply with the electric utility's Environmental Compliance Plan for the period the ECRM is in effect. 1. The costs for capital projects will be eligible for recovery via a periodic adjustment so long as the capital cost of the item when it is placed into service is greater than or equal to the original cost (as of the time that such least costly capital item was placed into service) of the least costly capital item that was included in the environmental revenue requirement (to be determined as provided in 4 CSR 240-20.091(1)(D)); and2. Waivers from the limitations in this subsection (4)(A) may be sought for capital projects placed into service that could not have been anticipated in the previous general rate proceeding or that do not meet the threshold provided for in the immediately preceding sentence.(B) The periodic adjustment shall reflect a comprehensive measurement of both increases and decreases to the environmental revenue requirement established in the prior general rate proceeding plus the additional environmental costs incurred since the prior rate proceeding.(C) Any periodic adjustment made to ECRM rate schedules shall not generate an annual amount of general revenue that exceeds two and one-half percent (2.5%) of the electric utility's Missouri gross jurisdic-tional revenues established in the electric utility's most recent general rate proceeding. 1. Missouri gross jurisdictional revenues shall be the amount established in the electric utility's most recent general rate proceeding and exclude gross receipts tax, sales tax, and other similar pass-through taxes not included in tariffed rates for regulated services;2. The electric utility shall be permitted to collect any applicable gross receipts tax, sales tax, or other similar pass-through taxes, and such taxes shall not be counted against the two and one-half percent (2.5%) rate adjustment cap; and 3. Any environmental costs, to the extent addressed by the ECRM, not recovered as a result of the two and one-half percent (2.5%) limitation on rate adjustments may be deferred, at a carrying cost each month equal to the utility's net of tax cost of capital, for recovery in a subsequent year or in the utility's next general rate proceeding.(D) An electric utility with an ECRM shall file one (1) mandatory adjustment to its ECRM in each true-up year coinciding with the true-up of its ECRM. It may also file one (1) additional adjustment to its ECRM within a true-up year with the timing and number of such additional filings to be determined in the general rate proceeding establishing the ECRM and in general rate proceedings thereafter.(E) The electric utility must be current on its submission of its Surveillance Monitoring Reports as required in section (9) and its monthly reporting requirements as required by 4 CSR 240-3.162(5) in order for the commission to process the electric utility's requested ECRM adjustment increasing rates.(F) If the staff, Office of the Public Counsel (OPC), or other party who receives the information that the electric utility is required to submit in 4 CSR 240-3.162 and as ordered by the commission in a previous proceeding, believes that the information required to be submitted pursuant to 4 CSR 240-3.162 and the commission order establishing the ECRM has not been submitted in compliance with that rule, it shall notify the electric utility within ten (10) days of the electric utility's filing of an application or tariff schedules to adjust the ECRM rates and identify the information required. The electric utility shall supply the information identified by the party, or shall notify the party that it believes the information provided was in compliance with the requirements of 4 CSR 240-3.162, within ten (10) days of the request. If the electric utility does not timely supply the information, the party asserting the failure to provide the required information must timely file a motion to compel with the commission. While the commission is considering the motion to compel, the processing time line for the adjustment to increase ECRM rates shall be suspended. If the commission then issues an order requiring the information be provided, the time necessary for the information to be provided shall further extend the processing time line for the adjustment to increase ECRM rates. For good cause shown the commission may further suspend this timeline. Any delay in providing sufficient information in compliance with 4 CSR 240-3.162 in a request to decrease ECRM rates shall not alter the processing timeline.(5) True-ups of an ECRM. An electric utility that files for an ECRM shall include in its tariff schedules and application, if filed in addition to tariff schedules, provision for true-ups on at least an annual basis which shall accurately and appropriately remedy any over-collection or under-collection through subsequent rate adjustments or refunds. (A) The subsequent true-up rate adjustments or refunds shall include interest at the electric utility's short-term borrowing rate. The interest rate on accumulated ECRM under-collections or over-collections shall be calculated on a monthly basis for each month the ECRM rate is in effect, equal to the weighted average interest rate paid by the electric utility on short-term debt for that calendar month. This rate shall then be applied to a simple average of the same month's beginning and ending cumulative ECRM over-collection or under-collection balance. Each month's accumulated interest shall be included in the ECRM over-collection or under-collection balances on an ongoing basis.(B) The true-up adjustment shall be the difference between the revenue collected and the revenue authorized for collection during the true-up period and billed revenues associated with the ECRM during the true-up period.(C) The electric utility must be current on its submission of its Surveillance Monitoring Reports as required in section (9) and its monthly reporting requirements as required by 4 CSR 240-3.162(5) at the time that it files its application for a true-up of its ECRM in order for the commission to process the electric utility's requested annual true-up of any under-collection.(D) The staff shall examine and analyze the information filed by the electric utility pursuant to 4 CSR 240-3.162 and additional information obtained through discovery, to determine whether the true-up is in accordance with the provisions of this rule, section 386.266, RSMo, and the ECRM established in the electric utility's most recent general rate proceeding. The staff shall submit a recommendation regarding its examination and analysis to the commission not later than thirty (30) days after the electric utility files its tariff schedules for a true-up. The commission shall either issue an order deciding the true-up within sixty (60) days of the electric utility's filing, suspend the timeline of the true-up in order to receive additional evidence and hold a hearing if needed, or, if no such order is issued, the tariff schedules and the ECRM rate adjustments shall take effect by operation of law sixty (60) days after the electric utility's filing. 1. If the staff, OPC, or other party who receives the information that the electric utility is required to submit in 4 CSR 240-3.162 and, as ordered by the commission in a previous proceeding, believes the information that is required to be submitted pursuant to 4 CSR 240-3.162 and the commission order establishing the ECRM has not been submitted or is insufficient to make a recommendation regarding the electric utility's true-up filing, it shall notify the electric utility within ten (10) days of the electric utility's filing and identify the information required. The electric utility shall supply the information identified by the party, or shall notify the party that it believes the information provided was responsive to the requirements, within ten (10) days of the request. If the electric utility does not timely supply the information, the party asserting the failure to provide the required information must timely file a motion to compel with the commission. While the commission is considering the motion to compel, the processing timeline for the adjustment to the ECRM rates shall be suspended. If the commission then issues an order requiring the information to be provided, the time necessary for the information to be provided shall further extend the processing timeline. For good cause shown, the commission may further suspend this timeline.2. If the party requesting the information can demonstrate to the commission that the adjustment shall result in a reduction in the ECRM rates, the processing timeline shall continue with the best information available. When the electric utility provides the necessary information, the ECRM shall be adjusted again, if necessary, to reflect the additional information provided by the electric utility.(6) Duration of ECRMs and Requirement for General Rate Case. Once an ECRM is approved by the commission, it shall remain in effect for a term of not more than four (4) years unless the commission earlier authorizes the modification, extension, or discontinuance of the ECRM in a general rate proceeding, although an electric utility may submit proposed rate schedules to implement periodic adjustments to its ECRM rates between general rate proceedings. (A) If the commission approves an ECRM for an electric utility, the electric utility must file a general rate case with the effective date of new rates to be no later than four (4) years after the effective date of the commission order implementing the ECRM, assuming the maximum statutory suspension of the rates so filed. (B) The four (4)-year period shall not include any periods in which the electric utility is prohibited from collecting any charges under the adjustment mechanism, or any period for which charges collected under the ECRM must be fully refunded. In the event a court determines that the ECRM is unlawful and all moneys collected are fully refunded as a result of such a decision, the electric utility shall be relieved of any obligation to file a rate case. The term fully refunded as used in this section does not include amounts refunded as a result of reductions in net environmental compliance costs or prudence adjustments.(7) Prudence Reviews Respecting an ECRM. A prudence review of the costs subject to the ECRM shall be conducted no less frequently than at eighteen (18)-month intervals. (A) All amounts ordered refunded by the commission shall include interest at the electric utility's short-term borrowing rate. The interest shall be calculated on a monthly basis in the same manner as described in subsection (5)(A).(B) The staff shall submit a recommendation regarding its examination and analysis to the commission not later than one hundred eighty (180) days after the staff initiates its prudence audit. The timing and frequency of prudence audits for each ECRM shall be established in the general rate proceeding in which the ECRM is established. The staff shall file notice within ten (10) days of starting its prudence audit. The commission shall issue an order not later than two hundred ten (210) days after the staff commences its prudence audit if no party to the proceeding in which the prudence audit is occurring files, within one hundred ninety (190) days of the staff's commencement of its prudence audit, a request for a hearing. 1. If the staff, OPC, or other party auditing the ECRM believes that insufficient information has been supplied to make a recommendation regarding the prudence of the electric utility's ECRM, it may utilize discovery to obtain the information it seeks. If the electric utility does not timely supply the information, the party asserting the failure to provide the required information must timely file a motion to compel with the commission. While the commission is considering the motion to compel the processing timeline shall be suspended. If the commission then issues an order requiring the information to be provided, the time necessary for the information to be provided shall further extend the processing timeline. For good cause shown, the commission may further suspend this timeline. 2. If the timeline is extended due to an electric utility's failure to timely provide sufficient responses to discovery, and a refund is due to the customers, the electric utility shall refund all imprudently incurred costs plus interest at the electric utility's short-term borrowing rate. The interest shall be calculated on a monthly basis in the same manner as described in subsection (5)(A).(8) Disclosure on Customers' Bills. Any amounts charged under an ECRM approved by the commission shall be separately disclosed on each customer's bill. Proposed language regarding this disclosure shall be submitted to the commission for the commission's approval.(9) Submission of Surveillance Monitoring Reports. Each electric utility with an approved ECRM shall submit to staff, OPC, and parties approved by the commission a Surveillance Monitoring Report in the form and having the content provided for by 4 CSR 240-3.162(6). (A) The Surveillance Monitoring Report shall be submitted within fifteen (15) days of the electric utility's next scheduled United States Securities and Exchange Commission (SEC) 10-Q or 10-K filing with the initial submission within fifteen (15) days of the electric utility's next scheduled SEC 10-Q or 10-K filing following the effective date of the commission order establishing the ECRM.(B) If the electric utility also has an approved fuel rate adjustment mechanism, the electric utility must submit a single Surveillance Monitoring Report for both the ECRM and the fuel rate adjustment mechanism. However, for the Surveillance Monitoring Report to be complete for the ECRM, it must include a list of all settlements in regards to environmental compliance causing the electric utility to incur expenses or make investments in excess of one hundred thousand dollars ($100,000) or fines against the electric utility in regards to environmental compliance greater than one hundred thousand dollars ($100,000) as required in 4 CSR 240-3.162(6)(A) 5.G.(C) Upon a finding that a utility has knowingly or recklessly provided materially false or inaccurate information to the commission regarding the surveillance data prescribed in 4 CSR 240-3.162(6), after notice and an opportunity for a hearing, the commission may suspend an ECRM or order other appropriate remedies as provided by law.(10) Pre-Existing Adjustment Mechanisms, Tariffs, and Regulatory Plans. The provisions of this rule shall not affect the following: (A) Any adjustment mechanism, rate schedule, tariff, incentive plan, or other ratemaking mechanism that was approved by the commission and in effect prior to the effective date of this rule; and(B) Any experimental regulatory plan that was approved by the commission and in effect prior to the effective date of this rule.(11) Nothing in this rule shall preclude a complaint case from being filed, as provided by law, on the grounds that a utility is earning more than a fair return on equity, nor shall an electric utility be permitted to use the existence of its ECRM as a defense to a complaint case based upon an allegation that it is earning more than a fair return on equity. If a complaint is filed on the grounds that a utility is earning more than a fair return on equity, the commission shall issue a procedural schedule that includes a clear delineation of the case timeline no later than sixty (60) days from the date the complaint is filed.(12) Rule Review. The commission shall review the effectiveness of this rule by no later than December 31, 2011, and may, if it deems necessary, initiate rulemaking proceedings to revise this rule.(13) Waiver of Provisions of this Rule. Provisions of this rule may be waived by the commission for good cause shown after an opportunity for a hearing.AUTHORITY: sections 386.250 and 393.140, RSMo 2000 and section 386.266, RSMo Supp. 2008.* This rule originally filed as 4 CSR 240-20.091.
