Employee Staffed Shared Facilities

Transparency Rule § 358.7 (e)(2)

"A transmission provider must post on its Internet website a complete list of the employee-staffed facilities shared by any of the transmission provider's transmission function employees and marketing function employees. The list must include the types of facilities shared and the addresses of the facilities."

Tri-State has two facilities shared by both Transmission function and Marketing function employees, as follows:

Tri-State’s Headquarters Building
Tri-State Generation and Transmission Association
Headquarters Building 
1100 W. 116th Avenue
Westminster, CO 80234

Tri-State’s Back-Up Control Center
The Back-Up Control Center is part of Tri-State’s Critical Energy Infrastructure and the address to that facility is not for public disclosure.

Both facilities are card-key controlled to restrict access to Marketing personnel.
