Existing TVA Supplier

We value our relationship with you, and have provided information and applications to help you effectively manage your contract with TVA.

Authenticator Change
Starting on February 27, there will be a change to the Microsoft Authenticator login process required to access the Maximo Supplier Portal application. For information and instructions, see tva.com/helpdesk.

Supplier Portal

TVA’s Supplier Portal is an EAM/Maximo system for contracted suppliers to view/update purchase orders, enter subcontracting accomplishments, respond to eRFQs, update limited company information and more.

IQNavigator

IQNavigator is a Vendor Management System (VMS) commonly used for staff augmentation or managed tasks contracts. For questions, contact your TVA sourcing representative or email TVA’s Contractor Workforce Management at cwmsupport@tva.gov.

InvoiceQuery

Use InvoiceQuery (VIQS) to search by your company ID or purchase order number to view related invoice and payment information. If interested, request access to VIQS by emailing accountspayable@tva.gov.

Web Contractor Security System (WCSS)

Suppliers coming onsite to perform work at TVA must check each employee/contractor through WCSS to verify suitability criteria and check for employment restrictions before access will be granted.

Safety and Health Plan

TVA expects all suppliers perform work at TVA to submit a plan at least 30 days prior to beginning work onsite to ensure a safety management system is in place.
