Tri-State Transmission Planning Process

Tri- State’s Tariff provides the best description of our transmission planning process:

“Tri-State’s transmission planning process is intended to facilitate the timely and coordinated development of transmission infrastructure that both maintains system reliability and meets customer needs, while continuing to provide reliable low cost electric power to its 44 member cooperatives.”

Tri-State Transmission Planning Objectives

• Network Customer service
• Point-To-Point Transmission Customer service
• System Reliability
• System load growth
• Coordinate interconnections with neighboring TPs
