SUPPLIERS

Managing the Supply Chain effectively has become ever more critical in today’s very competitive marketplace. For more than 60 years, TNB has been powering the nation’s progress and recognizes that success in this endeavor is supported by a strong supplier base. Without strong supplier relationships, especially in these challenging times, neither party will succeed.

By working together, TNB and its suppliers can both continue to grow in the future. Thus, we believe it is critical that our suppliers and contractors have a thorough understanding both of our business and our expectations of their performance.
