South Carolina Code 58-39-140. Submittal of estimates of incremental or avoided costs for the next twelve months; hearing; regulations; report; expiration
(1) The cost an electrical utility incurs in excess of the electrical utility’s avoided cost rate, as defined in this section. All costs paid under avoided cost rates, or negotiated rates pursuant to PURPA, whichever is lower, shall be considered an avoided cost under § 58-39-120(B) and shall be recovered under § 58-27-865.
Terms Used In South Carolina Code 58-39-140
- Avoided costs: means payments for purchases of electricity made according to an electrical utility's most recently approved or established avoided cost rates in this State or rates negotiated pursuant to PURPA, in the year the costs are incurred, for purchases of electricity from qualifying facilities pursuant to Section 210 of the Public Utility Regulatory Policies Act, said costs to be calculated as set forth in § 58-39-140(A)(1). See South Carolina Code 58-39-120
(2) The full cost of an electrical utility’s investment in nongenerating distributed energy resources, such as, but not limited to, energy storage devices.
(3) The electrical utility’s weighted average cost of capital as applied to the electrical utility’s investment in distributed energy resources. The weighted average cost of capital means the utility’s weighted average cost of (a) common equity, as most recently approved by the commission, and (b) long term debt. The capital costs of the resource shall include, but not be limited to, all reasonable and prudent costs associated with the design, siting, selection, acquisition, licensing, permitting, constructing, testing, and placing into service of the resource as well as capital maintenance and other capital costs associated with its repair, renewal, replacement, and upgrading. Such costs also shall include all reasonable and prudent costs incurred to expand, upgrade, or reconfigure transmission or distribution systems to accommodate power flows from the resource or to respond to other requirements placed by the resource on the electrical system, along with all other costs properly considered capital costs for a project or asset under generally accepted principles of regulatory or utility accounting or accounting orders issued by the commission. Capital costs shall include the utility’s weighted average cost of equity and long-term debt applied to the balance of construction work in progress for which capital costs are not yet being collected through a fuel cost component approved under this chapter and § 58-27-865.
(4) Operating and maintenance expenses, taxes, insurance, depreciation, overheads, and all other expenses properly considered to be expenses associated with a project, asset, or program under generally accepted principles of regulatory, or utility accounting or accounting orders issued by the commission, provided that such expenses shall be recorded as a capital cost of the resource or program until such time as a fuel cost component providing for their recovery goes into effect.
(5) The electrical utility’s incremental labor cost associated with implementing a distributed energy resource program.
(B) Upon approval of a distributed energy resource program, the commission shall direct the electrical utility which incurs incremental or avoided costs to submit to the commission and to the Office of Regulatory Staff, within such time and in such form as the commission may designate, its estimates of incremental or avoided costs for the next twelve months. The commission may hold a public hearing at any time between the twelve-month reviews to determine whether an increase or decrease in the fuel cost component designed to recover incremental or avoided costs should be granted. Upon conducting public hearings in accordance with law, the commission shall direct the electrical utility to place in effect an amount designed to recover, during the succeeding twelve months, the incremental or avoided costs determined by the commission to be appropriate for that period, adjusted for the over-recovery or under-recovery from the preceding twelve-month period. This amount shall be a component of the fuel cost factor established under § 58-27-865(A). The commission shall direct the electrical utility to send notice to the utility customers with the antecedent billing of the time and place of any public hearing to be held pursuant to this subsection, and the commission shall again direct the electrical utility to send notice to the utility customers with the next billing if the utility is granted a rate increase by the commission.
(C) Upon request by the Office of Regulatory Staff or the electrical utility, a public hearing must be held by the commission coincident with the fuel cost recovery proceeding required under § 58-27-865 to determine whether an increase or decrease in the fuel cost component designed to recover incremental or avoided costs should be granted. If the request is by an electrical utility for an increase or decrease in the fuel cost factor, the commission shall direct the utility to send notice of the request and hearing to all customers with the next billing, and if the commission grants the rate request subsequent to the request and hearing, the commission shall direct the utility to send notice of the amount of the increase or decrease to all customers with the next billing.
(D) The commission is authorized to promulgate, in accordance with the provisions of this section, all regulations necessary to allow the recovery by electrical utilities of all their prudently incurred distributed energy resource program implementation costs incurred pursuant to §§ 58-39-130 and 58-39-140 of this chapter.
(E) No later than July 31, 2016, the Office of Regulatory Staff shall prepare and submit to the General Assembly with copies to all members of the State Regulation of Public Utilities Review Committee a report on the implementation of this chapter and Chapter 40 of this title. The Office of Regulatory Staff shall update this report no later than July 31, 2017, and each two years thereafter. Upon receipt and review of these reports, and in consultation with the General Assembly, the Public Utilities Review Committee shall make recommendations to the Office of Regulatory Staff as to any changes in implementation that may be needed.
(F) The authorization to propose or approve new components of DER programs shall sunset and expire on January 1, 2021, provided however that the cost recovery provisions of this chapter shall remain in force until the costs associated with all approved DER program components have been recovered.
