GO 156 Certification for Businesses


Through the statewide Utility Supplier Diversity Program—established through General Order 156 (GO 156) and facilitated by the California Public Utilities Commission (CPUC)—the state aims to connect an increasing portion of these utility expenditures with certified minority-owned, women-owned, disabled veteran-owned, and/or LGBTQ-owned businesses (WMDVLGBTBEs).

In October 2019, Senate Bill 255 amended Public Utilities Code Section 366.2 to include Community Choice Aggregators (CCAs) into the Supplier Diversity Program. California Choice Energy Authority (CalChoice) is required to annually report spending from certified businesses, and we encourage all eligible businesses to pursue certification in the Supplier Diversity Program.


The key benefits of certifying your business in the Supplier Diversity Program include:

  • Official recognition: your business and certification credentials will be listed in the central, searchable Supplier Clearinghouse database
  • Promotion and visibility: many private sector companies—including major utility companies—actively seek business opportunities with WMDVLBGTBEs to meet specific procurement targets and listing in the Supplier Clearinghouse gives your business a valuable platform
  • Marketing and solicitation announcements: learn about new contracting opportunities as soon as they come out—many utilities use the Supplier Clearinghouse page to post bid opportunities and source potential certified business contacts.

Important note for disabled veteran-owned business enterprise

The Supplier Clearinghouse automatically recognizes DVBE firms certified by California Department of General Services (CA DGS)—no additional application is required. This is the only way to participate in The Supplier Clearinghouse’s program as a DVBE.
