Transpower as system operator prepares a forecast of demand at conforming grid exit points (GXPs) for each trading period. This information is a key input into the market schedules; in particular, the Week-ahead Dispatch Schedule (WDS), the Non-Response Schedule (NRS) and the Price-Responsive Schedule (PRS).
