Collaborative work results in FERC filing of Tri-State’s High Impact Load Tariff and Agreement
(August 29, 2025, Westminster, Colo.) Following months of collaboration with members and stakeholders, Tri-State Generation and Transmission Association on Thursday filed a proposed High Impact Load Tariff and Agreement with the Federal Energy Regulatory Commission (FERC).
The proposed tariff is designed to establish a repeatable and fair process for incorporating high impact loads onto the Tri-State system without adverse impacts to reliability or affordability. The process would allow Tri-State members to respond in a consistent manner to requests for services from heavy energy-users, such as data centers.
The new tariff will apply to load additions that exceed 45 megawatts (MW) at the time of the member project request, or is forecasted to exceed 45 MW within four years from the time of the member project request. The proposed agreement also includes provisions such as an upfront security payment, a minimum term, and minimum monthly demand and energy charges.
The Tri-State board, members and staff along with potential high-impact load customers, developers and other stakeholders participated in an interactive process in recent months to address important considerations and collaborate on a workable solution to help define the tariff and agreement.
“We’re in the business of providing electricity, and we are committed to doing it in a way that can meet the needs both of new loads and Tri-State members,” said Tri-State SVP Energy Management Lisa Tiffin. “This approach allows us to grow responsibly and limits the potential for stranded assets that could result in financial risk to Tri-State and our members.”
