AES Corporation is a global power company headquartered in Arlington, Virginia, with roughly $12 billion in annual revenue. It operates utilities, power plants, and renewable energy projects across the United States and more than 15 countries. In Indiana, AES owns Indianapolis Power & Light (now rebranded as AES Indiana), making it the dominant utility in the state. If your business sells into the energy sector, the infrastructure supply chain, or professional services that utilities buy regularly, AES is worth targeting.
This guide covers what AES buys, how their supplier registration works, which certifications carry real weight with their procurement team, and how to position a diverse business for its first contract.
What AES buys from external suppliers
AES spends across a wide range of categories. On the construction and infrastructure side, they source civil engineering services, electrical contractors, transmission and distribution equipment, steel structures, and heavy equipment rentals. Their shift toward renewables has expanded purchasing in solar panel components, battery storage systems, wind turbine services, and grid modernization equipment.
On the operations side, they buy fuel, environmental consulting, safety equipment, maintenance services, IT hardware and software, and facilities management. Corporate functions like legal, marketing, staffing, logistics, and financial services also go to external vendors.
For diverse businesses, the most accessible entry points tend to be in professional services, environmental and safety consulting, construction subcontracting, IT services, and logistics. These categories have faster procurement cycles than major capital equipment contracts, and they offer more opportunities for smaller businesses to build a track record inside the company.
How to register as an AES supplier
AES uses a centralized supplier portal called AES Supplier Diversity. You can find the registration link by searching for "AES Corporation supplier registration" or navigating to the Supplier Diversity section of their corporate website at aes.com.
During registration you will need to provide basic company information: legal business name, address, federal tax ID, DUNS or SAM.gov UEI number if you have one, and your primary NAICS codes. You will also be asked about your business ownership, certifications held, insurance coverages, and the categories of goods or services you supply.
Complete every section accurately. Incomplete profiles get deprioritized when procurement teams search the database. If you hold certifications from NMSDC or WBENC, enter those during registration and upload the certificate documents. Certifications are searchable fields, so buyers filtering for certified diverse suppliers will find you only if that data is in the system.
Update your profile when certifications renew, your capabilities change, or you add new service categories. Stale profiles drop out of search results over time.
Which certifications AES recognizes
AES participates in both NMSDC and WBENC, the two largest third-party diversity certification networks in the country.
NMSDC certification designates your business as a Minority Business Enterprise (MBE). To qualify, at least 51 percent of the business must be owned, operated, and controlled by a U.S. citizen or permanent resident who is Asian, Black, Hispanic, or Native American. Certification is issued by one of NMSDC's 23 regional affiliate councils. The process involves an application, document review, and a site visit. Annual fees typically run $350 to $1,200 depending on your revenue tier and council.
WBENC certification designates your business as a Women's Business Enterprise (WBE). To qualify, at least 51 percent must be owned and controlled by a woman or women who are U.S. citizens. WBENC certifies through its 14 regional partner organizations. Fees are similar to NMSDC.
Both certifications are nationally recognized and accepted by hundreds of Fortune 500 companies. If you are pursuing corporate supplier diversity broadly, getting certified by one or both organizations pays off across multiple corporate relationships, not just AES.
For AES's federal business and government contracting work, federal certifications like SDVOSB, WOSB, or 8(a) have less direct impact on corporate supplier selection, but they can signal credibility, especially when AES is working on federally funded projects.
How diverse certification affects your chances
AES has made public commitments to supplier diversity spending, which means their procurement team tracks what share of spend goes to certified diverse suppliers. That tracking creates internal pressure to include diverse vendors in sourcing events.
In practice, certification does two things for you. First, it makes you visible to buyers who filter by certification when building vendor shortlists. Without the tag in the system, you may never appear in those filtered searches. Second, it gives procurement teams a justified reason to select you when you are competitive on price and capability. Diverse certification does not override price or quality, but it helps when two or three vendors are otherwise comparable.
AES Indiana has specific supplier diversity goals tied to its regulated utility business. Regulated utilities in Indiana face state-level scrutiny on procurement practices, which gives diverse suppliers an additional structural advantage when bidding on AES Indiana contracts versus purely corporate AES work.
Getting your first order
Registration gets you in the database. It does not generate business on its own. Here is what moves the needle.
Identify the right procurement contact. AES has a Supplier Diversity team, typically led by a Supplier Diversity Manager or Director of Supply Chain. Their contact information is often published on the supplier diversity page of the AES corporate website. Reach out with a brief introduction after you register, referencing your certification and the specific categories you serve. One concise paragraph, not a capabilities brochure.
Attend AES supplier events. AES participates in NMSDC and WBENC national conferences and sometimes hosts regional supplier days or matchmaking events, particularly through AES Indiana's community programs. These events give you direct access to buyers and category managers who rarely respond to cold outreach but will have a 10-minute conversation at a conference table.
Target subcontracting. AES uses large prime contractors on major capital projects. If you cannot get a direct contract with AES, approach their primes. Many of AES's construction and engineering partners have their own supplier diversity programs and subcontracting requirements. Getting on a prime's approved vendor list can feed you AES work indirectly while you build your direct relationship.
Solve a specific problem. Generic vendor pitches do not convert. Before you reach out, find one service or product category where your business offers something specific: faster lead times, regional presence near an AES facility, a technical specialty in solar O&M, or MWBE certification that helps a prime contractor hit their own diversity targets. Specificity gets meetings.
Who handles supplier diversity at AES
The Supplier Diversity function sits within AES's Supply Chain organization. The relevant role is typically the Supplier Diversity Manager or Senior Manager, Supply Chain. For AES Indiana specifically, there may be a separate community or procurement contact aligned to state regulatory requirements. Current contact names and direct emails are listed on the AES supplier diversity page. Do not rely on role titles published in articles to reach the current person; check the website directly before outreach.
Supplier development programs and events
AES participates in NMSDC and WBENC-affiliated programming, which includes national conferences, regional business opportunity fairs, and capacity-building workshops. These events are the most reliable channel for meeting AES procurement staff outside of formal RFP processes.
AES Indiana has historically run community investment programs tied to its regulated utility status, which occasionally includes outreach to local diverse suppliers. Check the AES Indiana community or newsroom pages for current programs.
If you are an NMSDC or WBENC-certified business, your regional council will often know about upcoming matchmaking events with AES before those events are publicized broadly. Stay active with your certifying council and ask specifically about energy sector buyers on their calendar.
The suppliers who land first contracts with AES are rarely the ones who registered and waited. They registered, showed up at two or three events, followed up with the right person, and pitched a specific capability into a gap the buyer recognized. That cycle typically takes six to eighteen months from first contact to first purchase order, which is normal for a company this size.
