9.2 Intra-day Nominations

 

(a) Intra-day nominations are defined as nominations submitted

after the nomination deadline, whose effective time is no

earlier than the beginning of the gas day and runs through the

end of that gas day. Intra-day nominations can be used to

request increases or decreases in total flow, changes to

receipt points, or changes to delivery points of scheduled

gas. Intra-day nominations do not roll-over (i.e. intra-day

nominations span one day only). Intra-day nominations do not

replace the remainder of a standing nomination. There is no

need to renominate if intra-day nomination modifies existing

nomination. A Shipper may submit at least one (1) intra-day

nomination four (4) hours prior to gas flow.

 

(b) All nominations, including intra-day nominations, will be

based on a daily quantity; thus an intra-day nominator need

not submit an hourly nomination. Intra-day nominations must

include an effective date and time. The interconnected

parties must agree on the hourly flows of the intra-day

nomination, if not otherwise addressed in WNG's service

agreement or tariff.

 

(c) Except where specified in other GISB standards, all nomination

procedures that apply to regular nominations apply to

intra-day nominations. This means that the process (excluding

time lines) of quick response, confirming with upstream and

downstream parties, and scheduling, also applies to intra-day

nominations.
