At NRG, we value partnerships with suppliers who share our commitment to quality, compliance, sustainability, and service excellence.
Registering as a supplier allows our teams to learn more about your products and capabilities and consider your company for future sourcing opportunities.
Please note: Registration does not guarantee business with NRG, but it ensures your company is visible to our internal sourcing and procurement teams.
2. Who should register
You should complete supplier registration if your company provides:
- Goods (materials, equipment, components)
- Professional or consulting services
- Construction or field services
- Technology or software solutions
- Renewable energy products or services
- Business or operational support services
We encourage participation from small, local, and diverse suppliers.
3. Steps to register as a new supplier
The supplier registration process is designed to be straightforward and efficient.
- Submit supplier registration form
Provide basic company, contact, and service information via the Supplier PortaL
Upload required documentation
Documentation requirements vary by supplier type. At a minimum, suppliers are generally required to provide a completed W-9 or W-8, along with either a voided check or a bank letter. Safety and/or security qualifications may also be required, depending on the scope of work.
Complete compliance acknowledgements and process
Confirm acceptance of NRG policies and compliance standards.
Depending on the goods or services you provide, additional information or qualifications may be required:
Will your work require access to an NRG site or plant location?
Certain suppliers must meet safety qualification requirements through NRG’s third-party partner, ISNetworld (ISN).
Visit the Safety Qualifications page to understand what’s required.
Do you work with secure data, systems, or IT-related services?
Suppliers providing technology, cybersecurity, or data-related services may undergo a security review through Whistic.
Learn what to expect on the Security Qualifications page.
Are you a diverse, small, or local supplier?
