Supplier Registration

Please complete the new Supplier Prescreening Form and submit it along with your company’s brochure or other documents that highlight your company’s capabilities to suppliers@terrapower.com. TerraPower will not review incomplete application submissions. TerraPower reviews new suppliers on the last week of the month (submission cutoff is the 23rd of every month). Your information will be reviewed to determine whether your company capabilities are a good fit for future business opportunities. Note: If your company is comprised of different subsidiaries, divisions, or locations, a new entry will need to be submitted for each, if applicable.

Suppliers with favorable prescreening results and found to have capabilities that meet our needs will be contacted by a Contract Administrator (CA) who will provide onboarding instructions on how to register and create a profile in TerraPower’s Supplier Portal (BonFire). Please do not contact the CA directly for review status.

As a result of your registration, you may receive occasional emails notifying your company of future or existing opportunities. To learn more about how TerraPower handles your information, view our privacy policy.
