Introduction

We annually produce a 10-Year Transmission System Assessment based on engineering studies of the transmission system looking for potential problems that may affect the future performance of the system. Our studies identify and prioritize future projects needed to improve the adequacy and reliability of the electric transmission system for our customers and all electricity users in the region we serve.

This website reflects our 2024 10-Year Assessment. For more information about ATC, visit www.atcllc.com.
