Notice Text



For the most recent Quarter, Midwestern Gas Transmission (MGT) has had one (1) Operational Flow Order (OFO) event.   A system-wide OFO was issued due to receipt volumes surpassing delivery volumes creating a severe increase of line pack and operating pressure on the MGT pipeline system.  The OFO was effective beginning gas day Sunday, February 14, 2021 at 9:00 am and lifted effective gas day Sunday, February 14, 2021 at 10:00 pm as a result of customers taking the required actions to balance their receipt and delivery nominations.  


Net Pipeline Position (NPP):
During the Quarter, MGT issued four (4) postings for Net Pipeline Position in excess of +/- 25,000 dekatherms and Balancing Parties having a cumulative imbalance at or above 110% of their Allowable Swing Quantity in the direction of the NPP.  See MGT's Critical Notices on Informational Postings for detail of individual Net Pipeline Position which were posted as an OFO notice during the quarter.
