Standby Conditions:
a) system demand is greater than 80% of estimated peak demand, or
b) "bid to buy prices" for the Day are equal to the average summer gas price plus the injection commodity price plus the clearing price for the facility minus 0.1 p/kWh
and at other times at the discretion of LNG Storage
Notes:
State 1: Typically when a site is withdrawing gas
State 2: When a site is at a shortened withdrawal lead-time, but not withdrawing gas
Normal: Where a site is not at a state ready for withdrawing gas
For the avoidance of doubt a User will not be able to request that a particular facility be moved to a lead time of 1 hour ("State 1") as a facility will only move to that state when it is already flowing.
