Effective cap: for ESC, PRC, VEEC and LGC, the scheme shortfall penalty grossed up at the 30% company tax rate (where applicable).

PRCs held at $3.35-$3.40, keeping August's gains. NSW DCCEEW confirmed the 2027-28 target stays at 8.5%, an estimated 70 million certificates by March 2029, versus roughly 4 million for 2026-27. Forward prices for delivery after around $3.00, with expected supply from the BESS3-BESS5 apartment and large C&I battery activities that began on 1 September. IPART banned seven NEOVOLT battery models on 8 September.

ESCs traded $28.70-$29.80, a fifth month below $30, closing at $29.65. Registrations stayed low under the 1 July Rule; market participants report audit timeframes are constraining some providers. Further Rule changes took effect on 7 September. Market participants note a sustained rise in registrations would may see prices soften.

VEECs firmed from $83.50 to $86.50, peaking at $87.00 on 11 September. The VEET Strategic Review Act received Royal Assent on 8 September, enabling faster changes to activity settings and targets. Higher co-payments for larger heating and cooling installs applied from 30 September; ceiling insulation Stage 2 and four new industrial heat methods started on 1 October. The state election is on 28 November.

STCs were flat at $39.85, trading no higher than $39.90. Mid-scale solar regulations were made on 17 September: systems above 100 kW to 1 MW installed from 1 October can create STCs, with a fixed five-year deeming period. The CER expects applications to open in mid to late November. The Clearing House was around 3.6 million STCs in surplus at the start of October.

LGCs opened at the month's high of $8.40, fell to $7.10 on 18 September and closed at $7.85. The CER's June quarter QCMR (9 September) reported record Q2 creations (15.2 million) and non-RET surrenders (5.5 million). It estimates a balance of 32.5-37.5 million LGCs at the end of the 2026 compliance period, with supply outpacing demand, though sentiment improved on expected data-centre demand.

ACCUs eased from $38.95 to $38.45 (range $38.00-$38.95). Safeguard Mechanism Review submissions closed on 18 September. On 10 September the Senate rejected, 34-27, a motion to disallow the Improved Native Forest Management method. The CER reported a record 10.9 million ACCUs issued in the first half of 2026. The 2026-27 cost containment price is $87.72.

How to use this information now

For current use, confirm the applicable scheme rules, regulator notices, market date and reporting period. Keep historical prices or forecasts separate from present quotes and verified outcomes.

Separate source-reported facts from forecasts, targets and commentary. For a current project, retain the official source, version, effective date, assumptions and decision record in the evidence file.

What period do the certificate prices in this update cover?

They are historical September 2026 market observations published on 2 October 2026. The table reports that month's opens, closes and ranges; it is not a current quote. The page should be read with its status note and the live certificate-price page should be checked for later pricing.

Which certificate markets strengthened during September 2026?

The page reports that PRCs held August's gains at $3.35-$3.40, ESCs closed at $29.65 after trading from $28.70 to $29.80, and VEECs rose from $83.50 to $86.50 with a monthly high of $87.00. These are source-reported historical prices, not forecasts.

How did ACCUs, STCs and LGCs move in the September 2026 update?

ACCUs eased from $38.95 to $38.45 within a $38.00-$38.95 range. STCs remained near the $40 clearing-house cap at $39.85-$39.90. LGCs fell from $8.40 to $7.85 and reached $7.10 on 18 September. The article links those movements to the dated supply, demand and regulatory information available at publication.

What Peak Demand Reduction Scheme changes did the article identify?

The update says the NSW 2027-28 PDRS target was maintained at 8.5%, while the 2026-27 target remained 0.5%. It also records September rule and method-guide changes, new BESS3-BESS5 activities and the prohibition of seven named NEOVOLT battery models. Current IPART and NSW guidance should be checked before relying on those settings.

What Victorian Energy Upgrades developments were reported?

The article records Royal Assent for the Victorian Energy Upgrades Target legislation on 8 September 2026, revised co-payments for larger heating and cooling installations from 30 September, broader ceiling-insulation access and four industrial measurement-and-verification methods commencing on 1 October. Later regulations and program guidance prevail.

What did the update say about mid-scale solar and STCs?

It reports that regulations made on 17 September 2026 extended STC eligibility to systems above 100 kW and up to 1 MW when installed from 1 October 2026, with a fixed five-year deeming period. Applications were expected to open in mid to late November. Project owners should confirm the current Clean Energy Regulator process and eligibility before procurement.

Why should effective caps and spot prices be kept separate?

The effective caps shown in the article are derived from scheme shortfall penalties, including tax gross-up where applicable. They are not the same as the observed spot price, a guaranteed sale price or a forecast. A project model should identify the actual market date, transaction assumptions and any scheme or tax treatment used.

How should a business use this market update?

Use it as a dated market and regulatory snapshot. Confirm current prices, scheme rules, eligible activities, accreditation, evidence and registration timing before making a decision. The article is general factual information rather than financial product or investment advice, and historical prices do not predict future performance.
