S.C. Code Ann. § 58-42-10 Legislative findings.

(A) The General Assembly finds that it is in the public interest for the state's electrical utilities to competitively procure targeted volumes of renewable energy and co-located energy storage resources. The General Assembly further finds that it is in the public interest for the state's electrical utilities to competitively procure certain stand-alone storage additions to be located in South Carolina. These procurements shall be consistent with the electric utilities' 2023 integrated resource plans as approved by the commission or the subsequent annual integrated resource plan updates as approved by the commission. The resources procured pursuant to this section are intended to be placed in service on or before January 1, 2035. The volumes of each procurement may be increased or decreased as provided in this section. If an electrical utility proposes an amount of solar or storage in a future integrated resource plan filing that is lower than the amount contained in the electrical utility's 2023 integrated resource plan as approved by the commission, the electrical utility shall include and analyze at least one scenario consistent with the electrical utilities' 2023 preferred resource portfolio that includes volumes of solar and storage consistent with that contained in the 2023 integrated resource plans as approved by the commission. (B) The electrical utilities shall procure the resources referred to in subsection (A) through at least a biennial competitive procurement process consistent with the requirements of Sections 58-42-20 and 58-42-30, and in accordance with this section. The target volume in each competitive procurement shall be consistent with the volume of resources needed to be procured at that time to achieve the resource in-service dates specified in the electrical utility's 2023 integrated resource plan as approved by the commission or a subsequent integrated resource plan annual update as approved by the commission. (C) The amount of renewable energy or energy storage resources required to be procured by each electrical utility pursuant to this section shall be reduced by the alternating current ("AC") nameplate capacity of any facility of the same resource type for which such electrical utility enters into a power purchase agreement after the effective date of this section pursuant to the electrical utility's mandatory purchase obligation under Public Utility Regulatory Policies Act or pursuant to a prior competitive procurement which had not resulted in an executed power purchase agreement prior to the enactment date of this section, provided that the facility is placed in service in 2035 or earlier. (D) The target resource volumes for each competitive procurement shall reflect any increases or decreases included in the electrical utility's most recently approved integrated resource plan or integrated resource plan update. The electric utility may, at its option, include the procurement of non-renewable generation resources as part of its procurement of renewable and storage resources pursuant to this section. (E) The target resource volumes for competitive procurement shall take into account any changes in siting opportunities that may be affected by local permitting, zoning, or other regulatory or legal challenges. (F) The target resource volumes for competitive procurement by the electrical utility shall be increased to account for replacing megawatts associated with: (1) any inability by the electrical utility to reach target procurement volumes in prior procurement cycles; (2) the inability of renewable energy or energy storage resources procured in any prior procurement cycles to be placed in service; and (3) the expiration of any existing contracts with qualifying facilities pursuant to the Public Utility Regulatory Policies Act. All target resource volumes referenced in this subsection shall be consistent with the needs identified in the most recently commission approved integrated resource plan or integrated resource plan update. (G) Prior to making final awards in a competitive procurement, the electrical utility shall confirm that the resources selected are cost effective using methodologies and current inputs reflected in the applicable integrated resource plan or integrated resource plan update approved by the commission for that electrical utility. (H) Notwithstanding the other subsections of this section, the results of competitive procurements within an electrical utility's balancing area outside of South Carolina that serve customers in the electrical utility's balancing area within South Carolina shall be approved or accepted by the commission as specified in Section 58-42-20(G). (I) Notwithstanding Section 58-41-20(F)(2), electrical utilities shall continue to offer to qualifying small power production facilities power purchase agreements for the purchase of energy and capacity at avoided cost, with commercially reasonable terms and a duration of up to ten years, until the competitive procurement requirements of this section have been satisfied. Editor's Note 2025 Act No. 41, SECTION 1, provides as follows: "SECTION 1. This act may be cited as the 'South Carolina Energy Security Act.' " 2025 Act No. 41, SECTION 33, provides as follows: "SECTION 33. (A) To foster economic development and future jobs in this State resulting from the supply chains associated with the same while supporting the significant and growing energy and capacity needs of the State, enhance grid resiliency, and maintain reliability, the General Assembly finds that the State of South Carolina should take steps necessary to encourage the development of a diverse mix of long-lead, clean generation resources that may include nuclear and advanced nuclear, biomass as defined in Section 12-63-20(B)(2) of the S.C. Code, hydrogen-capable resources, fusion energy, and other technologies, and should preserve the option of efficiency development of such long-lead resources with timely actions to establish or maintain eligibility for or capture available tax or other financial incentives or address operational needs. "(B) For an electrical utility to capture available tax or other financial or operational incentives for South Carolina ratepayers in a timely manner, the commission may find that actions by an electrical utility in pursuit of the directives in Section 58-37-35(A) are in the public interest, provided that the commission determines that such proposed actions are in the public interest and reasonably balance economic development and industry retention benefits, capacity expansion benefits, resource adequacy and diversification and potential risks, costs, and benefits to ratepayers and otherwise comply with all other legal requirements applicable to the electrical utility's proposed action. For the South Carolina Public Service Authority, the Office of Regulatory Staff and the Public Service Authority's board of directors shall apply the same principles described in this subsection in evaluating and approving actions proposed by the management of the Public Service Authority to achieve the objectives of this section." 2025 Act No. 41, SECTION 41, provides as follows: "SECTION 41. (A) Five years after the effective date of this act, the Office of the Regulatory Staff shall prepare a report, to be filed with the Public Utilities Review Committee and the General Assembly, to address the implementation of Article 24, Chapter 27, Title 58 as it relates to the following areas: "(1) assessing the functioning of the procedures established by section with recommendation for any changes required to ensure their efficient functioning, to promote regulatory efficiency, and to make further the establishment of just, reasonable, and fair rates; "(2) assessing the effect of rates on ratepayers of all classes; "(3) assessing the reliability of the electric system and whether investments made by electric utilities increased reliability compared to any change in electric utility rates experienced by ratepayers within the same timeframe; and "(4) any other information requested by the General Assembly to be included within the report. "(B) The Office of Regulatory Staff may engage a qualified, independent third party to assist in preparation of the report. "(C) All expenses and charges incurred by the Office of Regulatory Staff in the performance of its duties within this section may be defrayed by assessments made by the Comptroller General against the regulated electrical utilities regulated and based upon twenty-five percent of the gross revenues collected by such electrical utilities from their business done wholly within this State in the manner set out in Section 58-4-60 for other corporations." 2025 Act No. 41, SECTION 42, provides as follows: "SECTION 42. Upon passage of this act, Dominion Energy shall evaluate the process for converting the Wateree Generating Station from coal-fired generation to biomass-fired generation. Biomass-fired generation includes, but is not limited to, generation from the firing of wood pellets and wood chips. Dominion Energy must make a report concerning the conversion process to the Public Service Commission and General Assembly by no later than January 13, 2026."

(7) The procurement of renewable energy facilities and co-located energy storage facilities and the output of such facilities shall result in a reasonable balance of electrical utility and independent third-party ownership of eligible facilities, as determined by the commission. The electrical utility and its affiliates may offer proposals into the competitive procurement provided that appropriate safeguards are in place to ensure that such proposals do not receive any advantage in the bid evaluation process. (D) An electrical utility shall make publicly available at least forty-five days prior to each competitive solicitation: (1) A commission-approved pro forma contract to inform prospective market participants of the procurement terms and conditions. The pro forma contract must: (i) include standardized and commercially reasonable requirements for contract performance security consistent with market standards; and (ii) define limits and compensation for resource dispatch and curtailment. (2) A bid and portfolio evaluation methodology that: (i) ensures all bids are treated equitably, including price and nonprice evaluation criteria; and (ii) ensures electrical utility and independent third-party owned facilities are treated equitably with regards to resource dispatch and curtailments. (3) Interconnection requirements including specification of how bids without existing interconnection studies must be treated for purposes of evaluation. (E) After bids are submitted and evaluated, final winning bids will be selected based upon the published evaluation methodology. (F) An electrical utility shall issue a public report summarizing the results of each competitive solicitation within sixty days of the award notifications. The report shall include, at minimum, a summary of the submitted bids and an anonymized list of the project awards, including their size, location, average award price and tenor, and award price range. Electrical utilities are permitted to recover costs incurred through such competitive procurement through rates established pursuant to Section 58-27-865 or Section 58-27-870. (G) Notwithstanding the requirements of Section 58-42-10 and this section, the commission shall approve an electrical utility's competitive procurement of energy storage facilities or renewable energy resources and the output of energy storage facilities or renewable energy resources within an electrical utility's balancing area outside of South Carolina that serve customers within South Carolina if eligible energy storage facilities or renewable energy resources located within South Carolina were allowed to participate in the competitive procurement and if the commission determines that the results of such procurement are in the public interest and enable the economic, reliable, and safe operation of the electric grid. Electrical utilities shall be permitted to recover costs incurred through such competitive procurements through rates established pursuant to Section 58-27-865 or Section 58-27-870. However, if the commission determines that the results of the procurement are not in the public interest for South Carolina, then the costs and benefits associated with such procurement shall be allocated away from South Carolina customers. (H) The commission is authorized to adopt rules or procedures for conducting a procurement authorized by this section. Editor's Note 2025 Act No. 41, SECTION 1, provides as follows: "SECTION 1.
