Transmission Planning Annual Stakeholder Outreach Meeting on October 17, 2011  To allow stakeholders the opportunity to participate in Tri- State’s transmission planning process consistent with:  Development of Tri- State’s system wide long-term transmission plans  Attachment L of Tri- State’s OATT  CPUC 3627  Generator Interconnection Procedures 4

Colorado Transmission Planning Stakeholder Outreach Meeting  This meeting focuses on Colorado transmission plans and CPUC Rule 3627.  The purpose of this meeting is to allow stakeholders the opportunity to:  Be involved in and aware of transmission plans  Provide feedback and ask questions  Identify alternative solutions for consideration  First meeting under the new CPUC Rule 3627 5

Overview of Tri-State  Tri-State is a member owned, not-for-profit , generation and transmission cooperative  44 member owners across NM (12), CO (18), NE (6), WY (8)  Members serve approximately 1.4 million  200,000 square miles of service territory  Mission Statement:  “Provide our member owners a reliable, cost -based supply of electricity while maintaining a sound financial position through effective utilization of human, capital and physical resources in accordance with cooperative principles.” 6

Tri-State G&T Member Cooperative Systems 7

Basic Statistics  Peak Member Load (Summer 2011) ~ 2654 MW  5 customers/ line mile average  Load by State  New Mexico 471 MW ~ 17%  Colorado 1729 MW ~ 61%  Nebraska 357 MW ~ 12%  Wyoming 277 MW ~ 10%  Diverse Membership  United Power – Brighton, CO – 65,000 meters – 300 MW  Garland L&P- Powell, WY – 1,900 meters – 6 MW 8

Tri- State’s Transmission System  Tri-State wholly or jointly owns 5,177 miles of transmission  1220 miles - 345 kV  984 miles - 230 kV  184 miles - 138 kV  2740 miles - 115 kV  49 miles - 69 kV  ~ 220 Stations  ~ 400 Communication Sites  DC Tie (Stegall, NE) 9

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 11
