36. Imbalance Netting and Trading

 

(a) Definitions. For purposes of this Section 36 the following definitions

shall be applicable:

 

(1) "Operational Impact Area" is the term used to describe Transporter's

designation of the largest possible area(s) on its system in which imbalances

have a similar operational effect.

 

(2) "Netting" is the term used to describe the process of resolving

imbalances for Shipper within an Operational Impact Area. There are two

types of Netting: (a) summing is the accumulation of all imbalances above

any applicable tolerances for Shipper or agent; and (b) offsetting is the

combination of positive or negative imbalances above any applicable tolerances

for Shipper or agent.

 

(b) Month-end Imbalances.

 

(1) Transporter shall allow Shipper (including agents of Shipper) to

net imbalances within the same Operational Impact Area on and across service

agreements with Shipper and to trade imbalances within the same Operational

Impact Area.

 

(2) Transporter shall provide Shippers the ability to post and trade

imbalances until at least the close of the seventeenth (17th) business

day of the month.

 

(3) Transporter shall provide Shippers the ability to view and, upon

request, download posted imbalances.

 

(4) Imbalances to be posted for trading should be authorized by Shipper.

 

(5) Authorizations to post imbalances that are received by Transporter by

11:45a.m. (C.T.) should be effective by 8:00a.m. (C.T.) the next business day.

Imbalances previously authorized for posting should be posted on or before the ninth

(9th) business day of the month.

 

(6) Transporter is not required to post zero imbalances.

 

(7) Netting, posting, and trading of imbalances shall be accomplished

based upon Transporter's current method for accounting for imbalances.

 

(8) Transporter shall enable the imbalance trading process by: receiving the

Request for Imbalance Trade, receiving the Imbalance Trade Confirmation, sending the

Imbalance Trade Notification, and reflecting the trade prior to or on the next

monthly Shipper Imbalance.

 

(9) When trading imbalances, Shippers shall specify a quantity.

 

(10) Imbalance trades can only be withdrawn by the initiating trader and

only prior to the confirming trader's confirmation of the trade. Imbalance trades

are considered final when confirmed by the confirming trader and effectuated

by Transporter.

 

(11) After receipt of an Imbalance Trade Confirmation, Transporter shall send

the Imbalance Trade Notification to the initiating trader and the confirming trader

no later than twelve (12) noon (C.T.) the next business day.

 

(12) To account for any imbalances after imbalance trading, where Transporter

associates such imbalance with a service agreement, Shipper and Transporter shall

agree to designate one of Shipper's valid service agreements in the Operational

Impact Area where the original imbalance occurred, for such purpose.
