Provides that in any proceeding in which the State Corporation Commission is required to determine whether costs incurred by a public utility in its delivery or provision of any goods or service are reasonable or prudent, the incremental portion of the costs incurred as a result of its contracting with a small, women-owned, or minority-owned business to deliver or provide the goods or service will not be found to be unreasonable or imprudently incurred if the costs of contracting with the small, women-owned, or minority-owned business do not exceed, by more than three percent, the costs that would have been incurred had it used the lowest-cost qualified business. The measure applies to businesses that are certified as small, women-owned, or minority-owned by the Department of Small Business and Supplier Diversity.
