Supplier Diversity

At Constellation:

Business Diversity is a business imperative that goes hand in hand with our commitment to Diversity, Equity, and Inclusion (DEI), Workforce Development, and Environment, Sustainability and Governance (ESG).  Business Diversity is at the core of what we do.  We know that partnering with diverse businesses leads to better outcomes for all. When underrepresented businesses are engaged, we enhance the economic impact of underserved communities we serve, while enabling innovative, high quality, and cost-effective solutions to better serve our customers.

  • We are committed to mentoring, promoting, and engaging diverse businesses resulting in greater representation, employment, and economic advancement for minorities, woman, veterans, small disadvantage business concerns, disabled and LGBTQ communities. Building these relationships also elevates the unique needs and talents of small, minority businesses, which benefits us all.

  • We search for suppliers who share this value and expect our suppliers to support our goals for diverse suppliers, including utilization of diverse prime and subcontractors, accurate reporting of diverse subcontracting and development of their own diversity programs.  

  • We are interested in partnering with diverse companies that can help us advance our four strategic principles:
    • Powering America's clean energy future
    • Expanding America’s largest fleet of Clean Energy Centers
    • Uplifting and strengthening our communities
    • Providing energy and sustainability solutions for customers
  • We seek to work with a diverse group of suppliers who share our commitment to the highest standards to deliver the best service for our customers.  

  • We view diversity-certified businesses as valued partners in our efforts to serve our customers, and we believe that partnership will help diverse business enterprises develop and grow.  Not only does this benefit Constellation, but it also empowers the community.

  • To be considered diverse, a business must be at least 51% owned by one or more individuals in the following classifications (Minority, Women, Veteran, Service-Disabled Veteran, Lesbian, Gay, Bisexual or Transgender, Disabled, or small disadvantage business). In addition, the owners must control the management and daily operations of the business.

  • We prefer diverse businesses get certified through National Minority Supplier Development Council (NMSDC), Women's Business Enterprise National Council (WBENC), National Veteran-owned Business Development Council (NVBDC), National LGBT Chamber of Commerce (NGLCC), Disability: IN, Small Business Administration (SBA), or be a Certified Federal HUBZone Business. 

Constellation expects suppliers to meet certain diversity goals in their own business. We ask current suppliers who are required to report Tier 2 spend to report monthly; please log-in below.

If you’re a new supplier and don’t have an existing company profile in the Constellation online sourcing application, please register here.

If your company has an existing profile in Constellation’s online sourcing application you will need to identify the Tier 2 Reporter for your company, if one is not identified the Primary Contact will receive all Tier 2 messages for the company.
