As a courtesy, Portland Natural Gas Transmission System (PNGTS) hereby notifies shippers and operators of the following notice posted by Maritimes & Northeast (M&N):
Maritimes & Northeast (M&N) has limited operational flexibility to manage imbalances. Effective 9:00 AM CCT, April 3, 2026, M&N requires all shippers and point operators to keep actual daily takes out of the system equal to or greater than scheduled quantities regardless of their cumulative imbalance position unless otherwise coordinated with your operations account representative.

Additionally, M&N continues to require all Power Plant Operators to provide information mandated by FERC Order No. 698 until further notice. Information required includes the hourly consumption profile of directly connected power generation facilities.
To the extent shippers and/or point operators do not adhere to this requirement,

This notice will remain in effect until further notice.
Please contact your Operations Account Representative if you have any questions.
