For potential nuclear plants located in other states, the costs must be those incurred before issuance of a certificate by the host state under statutes comparable to the Utility Facility Siting and Environmental Protection Act.(13) "Proceeding" means the proceeding to consider an application filed under this chapter.(14) "Project development application" means an application for a project development order.(15) "Project development order" means an order establishing the prudence of a utility's decision to incur preconstruction costs associated with a nuclear plant or potential nuclear plant.(16) "Return on equity" means the return on common equity established in the base load review order for a plant. But, if the order in the utility's most recent general rate proceeding was issued no more than five years before the date of filing of the application or combined application, or if such an order is issued after the application, combined application or base load review order related to the plant is filed, then at the utility's option, the rate of return on common equity established in that order shall be the rate of return used for computing future rate revisions under this article. A project-specific return on equity set hereunder shall apply exclusively to the establishment of the weighted average cost of capital under this article and shall not be used for reporting or any other purpose.(17) "Revised rates" means a revised schedule of electric rates and charges reflecting a change to the utility's then current nonfuel rates and charges to add incremental revenue requirements related to a base load plant as authorized in this article. For a nuclear plant under construction, until it enters commercial operation the rate adjustments related to the plant shall include recovery of the weighted average cost of capital applied to the outstanding balance of capital costs of that plant only and shall not include depreciation or other items constituting a return of capital to the utility. For a coal plant, no revised rates shall be allowed except that an adjustment under Section 58-33-280(J)(1) shall be permitted to take effect on or after the date commercial operations of the plant commence.(18) "Revised rates order" means an order issued by the commission approving, modifying, or denying the utility's request to charge revised rates under this article, which revised rates order an aggrieved party may contest in an adversarial hearing before the commission.(19) "Revised rates proceedings" means all proceedings to consider an application for revised rates or review of a revised rates order.(20) "Utility" means a person owning or operating equipment or facilities for generating, transmitting, or delivering electricity to South Carolina retail customers for compensation but it shall not include electric cooperatives, municipalities, the South Carolina Public Service Authority, or a person furnishing electricity only to himself, itself, its residents, employees, or tenants when the electricity is not resold or used by others.(21) "Utility Facility Siting and Environmental Protection Act" means Section 58-33-10 and other applicable provisions of this chapter.(22) "Weighted average cost of capital" or "cost of capital" means the utility's average cost of debt and equity capital: (a) incorporating the return on equity;(b) incorporating the utility's current weighted average cost of debt;(c) weighting (a) and (b) according to the utility's capital structure for ratemaking purposes, as established in the order in the utility's last general rate proceeding, updated to reflect the utility's current levels of debt and equity capital; and(d) adjusting the result for the effect of income taxes.(23) "Imprudent" or "imprudence" includes, but is not limited to, lack of caution, care, or diligence as determined by the commission in regard to any action or decision taken by the utility or one acting on its behalf including, but not limited to, its officers, board, agents, employees, contractors, subcontractors, consultants affecting the project, or any other person acting on behalf of or for the utility affecting the project. Imprudent or imprudence includes, but does not require, a finding of negligence, carelessness, or recklessness. Imprudence on behalf of any contractor, subcontractor, agent, or person hired to construct a plant or perform any action or service on behalf of the utility shall be attributed to the utility.
(24) "Prudent", "prudence", or "prudency" means a high standard of caution, care, and diligence in regard to any action or decision taken by the utility or one acting on its behalf including, but not limited to, its officers, board, agents, employees, contractors, subcontractors, consultants affecting the project, or any other person acting on behalf of or for the utility affecting the project. To the extent a utility enters a contract with a third party that delegates some or all decision-making authority related to the project, the utility retains the burden of establishing the prudency of specific items of cost or specific third-party decisions.
"Prudent", "prudence", or "prudency" also requires that any action or decision be made in a timely manner.
In determining whether any action or decision was prudent, the commission shall consider, including, but not limited to:
(a) whether the utility acts in a timely manner, with any passage of time which results in increased costs or expense prior to the utility acting or making the decision weighing against a finding of prudency;(b) whether prior actions or decisions by the utility were imprudent and such imprudent actions led to a decision by the utility that could otherwise be prudent. Such circumstances weigh against a finding of prudency; and(c) any other relevant factors, including commission of a fraudulent act, which are deemed not to be prudent. As used in item (c), "fraud" includes, in addition to its normal legal connotation, concealment, omission, misrepresentation, or nondisclosure of a material fact in any proceeding or filing before the commission or Office of Regulatory Staff. Proceedings and filings to which the provisions of this paragraph apply include, but are not limited to, rate or revised rate filings, responsive filings, motions, pleadings, briefs, memoranda, document requests, and other communications before the commission or Office of Regulatory Staff.
