Duke Energy is the largest electric utility in the United States by revenue, reporting more than $29 billion in annual revenue in 2024 and serving roughly 8.4 million electric customers across six states: North Carolina, South Carolina, Florida, Indiana, Ohio, and Kentucky. That footprint means a procurement operation that covers grid infrastructure, generation assets, facilities, professional services, technology, and everything in between.
The supplier diversity program is active and publicly committed. Duke Energy has set a goal to direct 5% of addressable procurement spend to diverse suppliers. The company is an NMSDC corporate member, meaning it participates in the minority supplier development council's matchmaking, reporting, and development infrastructure. This is not a program that exists only in the company's annual report.
Here is how to get in.
Duke Energy's supplier diversity program
Duke Energy's supplier diversity effort sits inside its Supply Chain organization. The program covers the full range of diversity designations: minority-owned (MBE), women-owned (WBE), veteran-owned (SDVOSB/VOSB), LGBTQ+-owned (LGBTBE), disability-owned (DOBE), and small business classifications including HUBZone and 8(a).
The 5% spend goal applies to addressable procurement, meaning the categories where diverse suppliers can realistically compete. For a company with $29 billion in revenue and a large capital expenditure program, even a small percentage of addressable spend is a significant dollar volume.
Duke Energy publishes its supplier diversity information at duke-energy.com. The supplier diversity page includes registration instructions, the certifications they recognize, and contact information for the Supply Chain team. It is worth reading that page before you register so your profile reflects what they are actively sourcing.
Which certifications carry weight
Duke Energy recognizes the major third-party diversity certifications used across corporate procurement programs:
MBE (Minority Business Enterprise) certified through an NMSDC affiliate regional council. The relevant councils for Duke's service territory include the Carolinas-Virginia Minority Supplier Development Council (CVMSDC) for the Carolinas, the Florida MSDC, and the Ohio MSDC. NMSDC certification is processed at the regional level; national recognition follows automatically.
WBE (Women's Business Enterprise) certified through WBENC or an equivalent state program. Duke's service territory includes Women's Business Enterprise Council Southeast (WBEC-Southeast) and WBEC-South as relevant regional affiliates.
SDVOSB / VOSB — Service-Disabled Veteran-Owned and Veteran-Owned Small Businesses, certified through the SBA's Veteran Small Business Certification program (formerly VA's VetBiz). Duke Energy has a meaningful presence in states with large veteran populations, and veteran-owned certification carries consistent weight.
LGBTBE (LGBTQ+ Business Enterprise) certified through NGLCC.
DOBE (Disability-Owned Business Enterprise) certified through Disability:IN.
Federal SBA certifications: 8(a), HUBZone, WOSB/EDWOSB through the federal WOSB program. These apply particularly if you are pursuing subcontract work on Duke's regulated utility projects or government-adjacent infrastructure.
State certifications from North Carolina, South Carolina, Florida, Indiana, Ohio, or Kentucky are recognized for state-contract work and are often accepted by Duke's Supply Chain team as supplemental credentials.
If you are choosing where to start your certification, NMSDC or WBENC is the right first move for businesses in Duke's service territory. Duke is an active NMSDC corporate member, which means those certifications get the most traction.
Where and how to register
Duke Energy uses its own supplier registration portal. The entry point is through the supplier section of duke-energy.com. You'll create a profile covering company details, capability codes (UNSPSC or similar), certifications held, geographic coverage, and the specific products or services you offer.
A few things that matter when completing your profile:
Use specific capability codes. Duke Energy's supply chain team searches the vendor database by commodity and service codes when they have an active sourcing need. "Energy services" is not a useful category code. If you provide transmission line construction, vegetation management, electrical engineering consulting, IT project management, or janitorial services for utility facilities, enter the specific code that matches. Duke's portal typically uses UNSPSC codes; review the code list before you fill out your profile.
Upload your certification documents. Attach your current certification certificate. Most third-party diversity certifications are valid for one year (NMSDC, LGBTBE) or up to three years (some WBENC cases). An expired certificate in your profile is functionally the same as no certificate. Set a calendar reminder before expiration.
Be accurate about geographic coverage. Duke Energy sources services in specific utility territories. If you operate in the Carolinas or Florida, say that. If you can cover multiple Duke territories, list them. Procurement teams match suppliers to active projects by region.
After registration, you are searchable in the database. That is the floor, not the ceiling. Duke Energy's procurement team uses the database actively, but staying current and following up through the channels below is what converts a profile into a conversation.
What product and service categories Duke Energy sources from diverse suppliers
Duke Energy's supply chain covers a wide range, reflecting the operational complexity of a large integrated utility:
Construction and engineering: transmission line construction, substation construction and maintenance, civil and structural engineering, underground cable installation, transformer and switch gear work. These are high-dollar categories with long qualification cycles; certifications and past utility project experience both matter.
Vegetation management and environmental services: rights-of-way clearing, tree trimming along transmission corridors, herbicide application, wetlands assessment. Duke manages thousands of miles of transmission lines across diverse terrain, and this is a consistently active sourcing category.
Facilities and real estate services: janitorial, security, landscaping, pest control, HVAC maintenance, building renovation for offices and field operations.
Technology and IT: software, hardware, IT consulting, cybersecurity services, data management, fiber and telecom infrastructure.
Professional services: consulting, legal support, financial services, staffing, communications, translation and interpretation (relevant given Duke's growing Spanish-speaking customer base in the Carolinas and Florida).
Fleet and logistics: vehicle maintenance and repair, fuel services, logistics coordination.
Fuel supply: natural gas supply and transportation, coal (declining but still active), biomass. Fuel supply is a specialized, highly qualified category; it is not an easy entry point for small diverse suppliers.
For new diverse suppliers, the fastest entry points are typically facilities services, professional services, vegetation management, and IT. Construction and engineering require demonstrated utility project experience and bonding capacity.
Practical tips for getting a meeting
Attend NMSDC events. The NMSDC Annual Conference & Business Opportunity Fair is the single best venue for getting face time with Duke Energy's supplier diversity team. Duke is an active NMSDC corporate member and participates in the conference's business opportunity sessions. If you are NMSDC-certified and not attending the annual conference or your regional council's matchmaking events, you are skipping the most direct path to Duke's procurement team.
Engage your regional NMSDC council. CVMSDC in Charlotte, the Florida MSDC, and the Ohio MSDC each run their own business development events and facilitate introductions between certified MBEs and their corporate members. Duke Energy is a corporate member of the relevant councils. These regional council events are specifically designed to produce introductions; they are not networking for networking's sake.
WBENC events. If you are WBENC-certified, WBEC-Southeast and WBEC-South both run matchmaking events and forums attended by Duke Energy. WBENC's national Summit and Salute is the other national venue worth attending if you can.
Disability:IN Annual Conference. Duke Energy participates in Disability:IN events. If you are a DOBE, this is the relevant event.
Direct outreach after registration. After completing your vendor profile, send a brief, direct email to Duke Energy's supplier diversity team introducing your company. Two paragraphs: what you do, your certification, your operating geography, and one concrete reason you fit their supply chain. Link your vendor profile. Do not send a 20-page capabilities deck as the first contact. Procurement contacts at utilities receive a high volume of outreach; specific and short gets a response where generic does not.
RFP responses. Duke Energy issues RFPs and RFQs through its procurement system for active projects. If your profile is current and your capability codes are accurate, you should be notified of relevant solicitations. When you get one, respond with a complete, on-time submission. An incomplete or late RFP response is a disqualifier, not a conversation opener.
Subcontracting. Duke Energy works with large prime contractors on construction, grid modernization, and capital projects. Those primes have their own diverse supplier goals. Getting on the sub list for a Duke prime is often a faster path to active revenue than pursuing the direct Duke relationship, particularly for small businesses building a track record.
Realistic timeline and what to expect
Registration to first purchase order at a major utility takes time. For professional services and facilities categories, a realistic window from first contact to first contract is six to eighteen months. Construction and engineering categories run longer because of prequalification, bonding, and project scheduling cycles.
The timeline shortens when there is an active RFP in your category or when a Duke project manager is sourcing a specific gap. That is why your capability codes and profile currency matter: the system only surfaces you if you are coded for the right category.
What does not work is registering once and waiting. The suppliers who win business at utilities show up at NMSDC and WBENC events, respond to every relevant RFP, keep their profiles current, and follow up after industry events with a specific note to the procurement contact they met. That consistency over six to twelve months is what produces a first contract.
If you are not yet certified, factor that into your timeline. NMSDC MBE and WBENC WBE certifications each take two to four months from application submission to approval, including document review and site visits. Start the certification process before you start supplier outreach so your credentials are in hand when Duke Energy asks for them.
Duke Energy's supplier diversity program is not a shortcut around capability requirements. The certification gets you visible; the contract still requires you to be a capable, compliant supplier who can deliver on a utility timeline. Come in with a clean safety record, adequate bonding or insurance, and references from comparable clients, and the program becomes a genuine accelerator.
