Tri-State, La Plata Electric Association terminate wholesale electric service contract  

(April 1, 2026, Westminster, Colo.) Tri-State Generation and Transmission Association and Colorado distribution cooperative La Plata Electric Association (LPEA) have jointly completed the previously announced termination of LPEA’s wholesale electric service contract with Tri-State. As part of the termination, LPEA withdraws from Tri-State membership effective April 1, 2026.  

LPEA provided an unconditional notice to leave Tri-State in late March 2024. Tri-State members can terminate their wholesale electric service contracts and withdraw from Tri-State by providing an unconditional two-year notice, and by  making a contract termination payment (CTP) under a tariff and formula ordered by the Federal Energy Regulatory Commission.   

LPEA’s CTP to Tri-State is approximately $208 million. In addition, LPEA received a credit for its patronage capital in Tri-State, resulting in a net payment of approximately $159 million for the distribution cooperative to exit from membership.  

LPEA joined the Tri-State membership in 1992, and later extended its contract in 2007, which would have run through 2050 before its decision to end membership.
