Final and interim energy prices

The wholesale market began operations on 1 October 1996 and until 1 November 2022 was settled on ex-post final prices. Real-time pricing was introduced on 1 November 2022. Under the real-time pricing regime, interim energy prices by node, or point of connection, and trading period are calculated as the time-weighted average of the dispatch energy prices pertaining to that period. Provided no pricing error claims are submitted, interim energy prices will be declared final by the pricing manager by 2pm the following business day.

Part 13 of the Code describes in detail how pricing in the wholesale market is undertaken.

Both interim and final energy prices will be published in this folder. Interim prices are indicated by the inclusion of an _I suffix in the file name. Final prices will be published without an indicative suffix and, at the time they are published, the interim price file for that day will be removed.

Following the end of each calendar year, and after all prices for the year have been finalized, the daily files will be accumulated into monthly files and located in the 'ByMonth' subfolder.
