The Authority introduced DSBF on 28 June 2012. The post-implementation review focuses on how the price forecasts that were created as a result of DSBF—the non-response schedule (NRS) and the price-responsive schedule (PRS)—performed. We found that the PRS is superior to the NRS across a number of measures for both single and multiple forecast horizons. This represents an improvement in forecast performance because the system operator prepares the NRS in the same way as it prepared the price forecast that pre-dated DSBF. This improvement in forecast performance should improve efficiency in the spot market by allowing better coordination of generation and load.

The Authority is surveying spot price exposed consumers and asking them which price schedule that they use to monitor spot prices—the results will be reported on this page once they are collated.
