What changed
The Electricity (Standard Products) Wholesale Arrangements 2014 is an instrument made under the Electricity Generation and Retail Corporation Scheme, the framework governing Synergy, the vertically integrated state-owned generator and retailer that dominates the South West Interconnected System. The Economic Regulation Authority is required to review the Scheme every two years.
Its 2025 review recommended three amendments. The Department of Energy and Economic Diversification consulted on an exposure draft, the Minister for Energy made the amendments, and they were gazetted on 11 August 2026. They commence on 30 September 2026.
- Pricing method disclosure. Synergy must publish further detail on the method by which it prices standard products.
- A 2023 error corrected. An error introduced in 2023 is rectified, so that Synergy is again restricted from offering buy-side standard products to entities with market power.
- References updated. Outdated references across the instrument are brought current.

submission was received on the exposure draft amending the Wholesale Arrangements
| Amendment | What it does | Type |
|---|---|---|
| Pricing method disclosure | Requires Synergy to publish further detail on the method by which it prices standard products | New obligation |
| Buy-side restriction | Rectifies an error introduced in 2023, restoring the restriction on offering buy-side standard products to entities with market power | Correction |
| References | Updates outdated references across the instrument | Housekeeping |
All three were recommended by the Economic Regulation Authority in its 2025 review of the EGRC Scheme. Only the first creates something that did not exist before.
Why the first amendment is the one that matters here
The standard products regime exists so that parties other than Synergy can hedge wholesale electricity in a market where one participant holds most of the generation and most of the load. The price at which those products are offered, and the method behind that price, is the mechanism by which the regime either works or does not.
Requiring further detail on the pricing method is a transparency obligation rather than a price control. It does not change what Synergy may charge. It changes what a counterparty, or an observer, can see about how the charge was arrived at. On a system where the same entity sets the terms it also trades on, the distinction between a price and a published method for reaching it is most of the accountability available.
The second amendment is a three-year gap, now closed
The restriction on offering buy-side standard products to entities with market power is a structural protection: it exists so the regime is not used to concentrate position further. The notice records that an error introduced in 2023 undid it, and that this amendment restores it.
What the notice does not state is whether anything turned on the gap in the intervening period. That question is not answerable from the instrument or the notice, and it is not answered here.
One submission
The consultation on the exposure draft ran to 9 June 2026 and received a single submission. That is the figure most worth carrying forward from this notice.
It is not, by itself, evidence of anything wrong. Instrument-level amendments recommended by an economic regulator and consulted on as an exposure draft are technical work, and a low response can as easily mean the drafting was uncontroversial as that nobody was watching. But the subject was a disclosure obligation on the dominant participant in the SWIS wholesale market, and the market it governs has more than one participant with an interest in how Synergy prices. A single submission is a measure of the attention this layer of the WA market attracts, and it is a low one.
What to watch from 30 September
The test of the first amendment is what Synergy publishes once it commences, and whether the additional detail is sufficient for a counterparty to reconstruct how a standard product price was reached. Solar Analytica records this as a forward check rather than a finding: the obligation exists from 30 September 2026, and the published method is the artefact to read.
