This document is updated on a weekly basis and outage schedules/impacts are subject to change as the week progresses.

Dates posted on DART should be deemed correct in the event of conflicts between DART posted dates and dates on this report.

The impacts sheet are based on steady-state hydraulic models assuming recent operating flows, conditions, and various unit outages.

-Primary impact restrictions may be necessary

TGP - Outage Impact Report

-Major impact restrictions may be necessary

December 2024 (updated 11/07/24)

-Minor impact restrictions may be necessary depending on flow conditions

-Little to no impact, though minor outages may cause incremental reductions
