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 2013 10-Year Assessment. Also see our 2013 Summary Report. For more information about ATC, visit www.atcllc.com.
