Variable Transfer Limits (VTL) Study Complete - Final Report Posted


In June 2014, ColumbiaGrid began a process to coordinate technical analyses, as performed through a third-party contractor, to calculate the Variable Transfer Limits of the Northwest AC Intertie. The analyses were performed pursuant to the Dynamic Transfer Capability (DTC)Study Methodology and California - Oregon Intertie (COI) Statement of Work which were established through a collaborative effort, led by ColumbiaGrid, among the owners, operators, and purchasers of long-term transmission rights of the California-Oregon Intertie, including members of ColumbiaGrid and Northern Tier Transmission Group, Pacific Northwest Generating Cooperative, and the California Independent System Operator.

In accordance with section 1.1 of the Variable Transfer Limits Functional Agreement, ColumbiaGrid has posted the COI VTL Study Final Report on its website at: https://www.columbiagrid.org/variabletransferlimits-overview.cfm.

"In ColumbiaGrid, we now have the ability to resolve the three fundamental transmission questions: What transmission facilities should be built? Who should build them? Who should pay for them? With ColumbiaGrid's independent staff and process to resolve disputes, we can answer these questions effectively and in a timely fashion to facilitate our region's new resource development needs."
