Participation from Diverse Business Enterprises
SDG&E analyzes the qualitative aspects of each conforming offer to determine how well the offer aligns with the priorities set out by the CPUC, including supplier diversity. In accordance with the CPUC’s General Order 156 (GO 156), SDG&E supports the utilization of Diverse Business Enterprises (DBEs) owned and controlled by women, minorities, disabled veterans, members of the LGBT community and persons with disabilities, as well as Small Business Administration 8(a) enterprises. Furthermore, SDG&E encourages developers to consider utilizing DBE subcontractors during various stages of project development and construction, solely to the extent that they are the most competitive bid for the work in question. To comply with the CPUC’s annual supplier diversity reporting requirement, SDG&E will require developers to report their DBE subcontractor spending, if any, each month via its DBE Subcontracting Spend Portal. Under GO 156, supplier diversity goals are not rigid, inflexible requirements or quotas, which are expressly forbidden and shall not be used to exclude any qualified businesses from participating in contracting opportunities under this RFO.
SDG&E provides equal opportunities for businesses owned by all persons without regard to race, sex and other traits protected by law and makes all decisions about suppliers without regard to protected traits. SDG&E expects developers and developers’ subcontractors to utilize business enterprises without regard to protected traits.
