(2) "Base load plant" or "plant" means a new coal or nuclear fueled electrical generating unit or units or facility that is designed to be operated at a capacity factor exceeding seventy percent annually, has a gross initial generation capacity of three hundred fifty megawatts or more, and is intended in whole or in part to serve retail customers of a utility in South Carolina, and for a coal plant, includes Best Available Control Technology, as defined by the United States Environmental Protection Agency, for the control of air emissions.

(3) "Base load review application" or "application" means an application for a base load review order under the terms of this article.

(4) "Base load review order" means an order issued by the commission pursuant to § 58-33-270 establishing that if a plant is constructed in accordance with an approved construction schedule, approved capital costs estimates, and approved projections of in-service expenses, as defined herein, the plant is considered to be used and useful for utility purposes such that its capital costs are prudent utility costs and are properly included in rates.

(5) "Capital costs" or "plant capital costs" means costs associated with the design, siting, selection, acquisition, licensing, construction, testing, and placing into service of a base load plant, and capital costs incurred to expand or upgrade the transmission grid in order to connect the plant to the transmission grid and includes costs that may be properly considered capital costs associated with a plant under generally accepted principles of regulatory or financial accounting, and specifically includes AFUDC associated with a plant and capital costs associated with facilities or investments for the transportation, delivery, storage, and handling of fuel.

(6) "Combined application" means a base load review application which is combined with an application for a certificate under the Utility Facility Siting and Environmental Protection Act, or which involves a plant located outside of the State of South Carolina, and at the utility’s option may be combined with an application for new electric rates under § 58-27-860.

(7) "Combined proceeding" means a proceeding to consider all aspects of a combined application.

(8) "Construction work in progress" means capital costs as defined above associated with a base load plant which have been incurred but have not been included in the utility’s plant-in-service.

(9) "General rate proceeding" means a proceeding under § 58-27-810 and other applicable provisions for the establishment of new electric rates and charges, and where orders in general rate proceedings are referenced in this article, these orders include rate orders issued in proceedings or combined proceedings under this article.

(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.

(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.
