Notice Text

An OFO watch/daily imbalance charge warning has been placed on the following LMS Balancing Parties:

Duke Energy Indiana, Inc
Duke Energy Indiana, Inc
Duke Energy Indiana, Inc.
Marshall, City of


For 02/21/2021, gas day recently ended, Midwestern Gas Transmission's Net Pipeline Position is in excess of +/- 25,000 dekatherms.  In addition, the above referenced Balancing Parties each have a cumulative imbalance that is at or above 110% it's Allowable Swing Quantity (ASQ) in the direction of the NPP.  The warned parties can find their ASQ on the daily OBA imbalance report.

Midwestern Gas Transmission is requesting that these Balancing Parties take immediate action to correct this out of tolerance imbalance situation.  Failure to do so will prompt Midwestern to 1) invoke the Daily Imbalance Charge for the portion of the cumulative imbalance that is out of tolerance for the gas day identified above as well as 2) issue an OFO Warning for the physical interconnect locations covered by the penalized Balancing Parties.

The Midwestern Gas Transmission Informational Posting site has a complete listing of the physical interconnects locations that could be affected by an OFO Warning - specifically refer to the posting of those parties subject to the Daily Imbalance Charge.
