Sec. 89.
(1) The commission shall allow a provider whose rates are regulated by the commission to recover the actual costs of implementing its approved energy waste reduction plan. However, costs exceeding the overall funding levels specified in the energy waste reduction plan are not recoverable unless those costs are reasonable and prudent and meet the utility system resource cost test. Furthermore, costs for load management undertaken by an electric provider pursuant to an energy waste reduction plan are not recoverable as energy waste reduction program costs under this section, but may be recovered as described in section 95.
(2) Under subsection (1), costs shall be recovered from all natural gas customers and from residential electric customers by volumetric charges, from all other metered electric customers by per-meter charges, and from unmetered electric customers by an appropriate charge. Fixed, per-meter charges under this subsection may vary by rate class. Charges under this subsection may be itemized on utility bills but shall not be itemized on or after January 1, 2021.
(3) Upon petition by a provider whose rates are regulated by the commission, the commission shall authorize the provider to capitalize all energy efficiency and energy conservation equipment, materials, and installation costs with an expected economic life greater than 1 year incurred in implementing its energy waste reduction plan, including such costs paid to third parties, such as customer rebates and customer incentives. The provider shall also propose depreciation treatment with respect to its capitalized costs in its energy waste reduction plan, and the commission shall order reasonable depreciation treatment related to these capitalized costs. A provider shall not capitalize payments made to an independent energy waste reduction program administrator under section 91.
(4) The established funding level for low income residential programs shall be provided from each customer rate class in proportion to that customer rate class's funding of the provider's total energy waste reduction programs. Charges shall be applied to distribution customers regardless of the source of their electricity or natural gas supply.
(5) The commission shall authorize a natural gas provider that spends a minimum of 0.5% of total natural gas retail sales revenues, including natural gas commodity costs, in a year on commission-approved energy waste reduction programs to implement a symmetrical revenue decoupling true-up mechanism that adjusts for sales that are above or below the projected levels that were used to determine the revenue requirement authorized in the natural gas provider's most recent rate case. In determining the symmetrical revenue decoupling true-up mechanism utilized for each provider, the commission shall give deference to the proposed mechanism submitted by the provider. The commission may approve an alternative mechanism if the commission determines that the alternative mechanism is reasonable and prudent. The commission shall authorize the natural gas provider to decouple rates regardless of whether the natural gas provider's energy waste reduction programs are administered by the provider or an independent energy waste reduction program administrator under section 91.
