What’s the difference between firm and interruptible receipt point capacity?
The RPAC will have either firm or IT capacity. The firm capacity will be specific to a receipt point and will be designated Firm Primary. This firm capacity may also be used at any other receipt point and will be designated as either Firm Alternate Within the Zone or Firm Alternate Outside the Zone. The zones are North Desert, South Desert, Wheeler Ridge, Line 85 and Coastal. An RPAC with IT capacity may be nominated at any receipt point and will be, of course, designated as interruptible.
