We ask all suppliers and potential suppliers to be registered in our sourcing database. It takes just a few minutes to create your profile.

Prospective Suppliers

A relationship with Exelon starts here.

Exelon has a supplier-sourcing database. We want your business in that database, with a profile you create that helps us know your business and the ways in which you might help ours. Once you’ve registered, you will receive a confirmation message from the system that you have successfully created a supplier profile.

When you register and create a profile, your company is simply brought to our attention.


Being registered implies no promise of a contract or contracts.

Registration allows Exelon to more easily identify potential suppliers whom Exelon may want to choose to participate in a sourcing event and compete for work. Contract awards follow Exelon’s established procedures for competitive bidding, evaluation and negotiation. The steps in the competitive bidding process include a thorough financial and quality assurance evaluation to ensure suitability with Exelon’s standards of excellence. Registration does not imply a promise by Exelon to either include a supplier in a sourcing event or enter into a contract(s) for work.


How you become an approved bidder for Exelon business.

Exelon sourcing professionals search the sourcing database to identify potential bidders when a future need for services or materials is identified. As we seek to enhance our relationship with premier suppliers, we also look for opportunities to build partnerships with new suppliers who are environmentally responsible with a keen focus on safety and superior quality. If your company matches our search criteria an additional request for information (RFI) may be issued for clarifications and additional detail; or a formal solicitation to participate in a sourcing event may be issued. In all cases, you will receive an email notification inviting you to participate should the opportunity arise.

Exelon requires current and prospective suppliers to maintain updated profiles at least annually.
