ASX Australian Electricity Futures Daily Settlement Price methodology changes – Notification of Implementation Date
Wed 11 Jun 2025
As per Notice 0585.25.06, following market Notice 0340.25.04, ASX will make changes to the Daily Settlement Price (DSP) for Australian Electricity Futures. The implementation of the changes will take place on Saturday, 21 June 2025, effective Monday, 23 June 2025, subject to internal readiness.
Overview of the changes:
Details of the changes to be made can be viewed in the ASX Electricity Futures and Options Contracts – Daily Settlement Price Methodology document and are described below:
In Part A (1) (as described in ASX Electricity Futures and Options Contracts – Daily Settlement Price Methodology document):
- The Trade Pre-Close Period (VWAP calculation window) will be amended from two minutes to ten minutes.
- The order hold time is being increased from ten seconds to sixty seconds. Preliminary Daily Settlement Price will not be generated at levels less competitive than eligible Outright Orders at market close.
Subsequent steps of the process are described in ASX 24 Operating Rules 2500.1(a)(ii) to (iii).
Notes:
- Orders must be held and unchanged, i.e. price and volume of the order remain unmodified, for sixty seconds prior to the close of market (“Order Pre-Close Period”).
- This will not preclude orders of shorter duration entering the market; however, these orders will not be included in the DSP calculation.
What do I need to do by when?
Market participants should advise their Electricity clients of the change to the Australian Electricity Futures methodology. If you have any feedback, please provide this to commodities@asx.com.au.
