# Tariff sources for the power-cost calculator

Accessed 12 November 2026 (Australia/Sydney). Figures are residential flat (anytime) usage rates only, used as c/kWh presets the user can override. The calculator does not add a daily supply charge. No state average was invented: where a state has more than one official network rate, each named network is listed separately. Where a regulator did not publish a per-kWh usage rate, the preset is left blank.

## NSW, Queensland (South East), South Australia — AER Default Market Offer

- **Document:** Australian Energy Regulator, *Default market offer prices 2026–27: Final determination* (DMO 8), May 2026.
- **URLs:** [Final determination PDF](https://www.aer.gov.au/system/files/2026-05/AER%20-%20Final%20determination%20-%20Default%20market%20offer%202026%E2%80%9327.pdf) and the [AER Default Market Offer page](https://www.aer.gov.au/industry/retail/default-market-offer).
- **Period:** 1 July 2026 to 30 June 2027.
- **What the figure is:** From DMO 8 the AER publishes a tariff cap in two parts: a daily supply charge (c/day) and a variable usage charge (c/kWh). The preset uses the **residential flat-rate usage cap** for the named distribution region, not the annual comparison price (which is a typical-bill figure and is not used here). Appendix section “Tariff cap price determination for regulated tariffs”, item (1) *Residential Customers Flat Rate Tariff Cap Price Determination*. **All prices GST-inclusive.**
- **Figures used:**
  - NSW — Ausgrid: **33.1372 c/kWh**
  - NSW — Endeavour Energy: **33.7273 c/kWh**
  - NSW — Essential Energy: **35.0054 c/kWh**
  - QLD — Energex (South East Queensland only): **27.9744 c/kWh**. The DMO does not cover regional Queensland (Ergon).
  - SA — SA Power Networks: **41.9103 c/kWh**
- The AER page also shows these usage caps rounded to two decimal places (for example 33.14 c/kWh for Ausgrid). The calculator uses the more precise figures from the determination.

## Victoria — Essential Services Commission Victorian Default Offer

- **Document:** Essential Services Commission, *Victorian Default Offer* current prices, and *Victorian Default Offer Price Determination 2026–27* (1 July 2026 to 30 June 2027).
- **URLs:** [VDO page](https://www.esc.vic.gov.au/electricity-and-gas/prices-tariffs-and-benchmarks/victorian-default-offer) and the [Price Determination PDF](https://www.esc.vic.gov.au/sites/default/files/documents/Victorian%20Default%20Offer%202026-27%20Price%20Determination.pdf).
- **Period:** 1 July 2026 to 30 June 2027.
- **What the figure is:** **Domestic (residential) fixed flat general-usage charge**, not controlled load, published in dollars per kWh, GST inclusive. Converted to c/kWh by multiplying by 100 (for example $0.3198/kWh = 31.98 c/kWh). No average across Victorian networks was taken.
- **Figures used:**
  - AusNet Services: **$0.3198/kWh = 31.98 c/kWh** (blocks 1 and 2 are the same rate)
  - CitiPower: **$0.2596/kWh = 25.96 c/kWh**
  - Jemena: **$0.2747/kWh = 27.47 c/kWh**
  - Powercor: **$0.2822/kWh = 28.22 c/kWh**
  - United Energy: **$0.2735/kWh = 27.35 c/kWh**

## Tasmania — Office of the Tasmanian Economic Regulator / Aurora standing offer

- **Document:** Office of the Tasmanian Economic Regulator, *Current Regulated Prices*, “2026-27 Standing Offer electricity prices (GST inclusive)”.
- **URL:** [https://www.economicregulator.tas.gov.au/for-customers/current-regulated-prices](https://www.economicregulator.tas.gov.au/for-customers/current-regulated-prices)
- **Period:** 2026–27 standing offer (as published on the OTTER page; read 12 November 2026).
- **What the figure is:** Aurora **Tariff 32, Residential flat rate**, usage **24.7500 c/kWh**, GST inclusive. This is the current residential flat usage rate. Tariffs 31, 41 and 61 are no longer available to new connections; Tariff 93 is a time-of-use rate and is not used as the flat preset.
- **Figure used:** **24.75 c/kWh**

## Western Australia — WA Government (Synergy / Horizon regulated residential)

- **Document:** Government of Western Australia, Energy Policy WA, *Household electricity pricing* (last updated 14 July 2026).
- **URL:** [https://www.wa.gov.au/organisation/energy-policy-wa/household-electricity-pricing](https://www.wa.gov.au/organisation/energy-policy-wa/household-electricity-pricing)
- **Period:** Prices “current as of 1 July 2026”. The page does not state an end date.
- **What the figure is:** Regulated **Residential electricity tariff A1 and A2**, “Electricity charge — cents per unit”, where one unit is 1 kWh, under the Uniform Tariff Policy (same rate for eligible Synergy and Horizon Power small-use customers).
- **Figure used:** **33.2621 c/kWh**
- **GST:** The WA Government page does not itself say whether the table is GST inclusive. The same 33.2621 c/unit A1 electricity charge is published as **including GST** in Synergy’s *Standard Electricity Prices and Charges* brochure, “correct as at 1 July 2026, include GST”: [https://www.synergy.net.au/-/media/Files/PDF-Library/Standard_Electricity_Prices_Charges_brochure.pdf](https://www.synergy.net.au/-/media/Files/PDF-Library/Standard_Electricity_Prices_Charges_brochure.pdf)

## Northern Territory — Jacana Energy (prices set by the NT Government pricing order)

- **Document:** Jacana Energy, *Pricing and tariffs – Residential*. The page states that residential retail prices are regulated by the Northern Territory Government through the electricity pricing order.
- **URL:** [https://www.jacanaenergy.com.au/residential/pricing](https://www.jacanaenergy.com.au/residential/pricing)
- **Period:** Valid from 1 July 2026 to 30 June 2027.
- **What the figure is:** **Standard Residential** unit price **31.6788 cents per kWh including GST** (28.7989 c/kWh ex GST). This rate applies to the first 164 kWh of electricity used each day, averaged over the billing period; usage above that is charged at a rate equal to the standard business tariff. The calculator uses the standard residential rate and notes the threshold.
- **Figure used:** **31.6788 c/kWh** (GST inclusive)
- The Utilities Commission of the NT confirms that retail prices are set by a Treasurer’s Electricity Pricing Order and links [Electricity Pricing Order 1 July 2026 – 30 June 2027](https://utilicom.nt.gov.au/__data/assets/pdf_file/0017/1620350/2026-27-revised-electricity-pricing-order.pdf) from [its retail pricing page](https://utilicom.nt.gov.au/electricity/price-regulation/electricity-retail-pricing). That PDF had no extractable text (image-only) when fetched on 12 November 2026, so the published per-kWh figure used here is the Jacana table, not a number read from the order file.

## Australian Capital Territory — ICRC (no per-kWh preset)

- **Document:** Independent Competition and Regulatory Commission, *Report 2 of 2026, May 2026: Retail electricity price recalibration 2026-27: standing offer prices for the supply of electricity to small customers*.
- **URLs:** [ICRC retail electricity prices 2024–27 page](https://www.icrc.act.gov.au/energy/electricity/retail-electricity-prices-2024-27) and the [recalibration report PDF](https://www.icrc.act.gov.au/__data/assets/pdf_file/0010/3072781/Report-Retail-electricity-price-recalibration-2026-27.pdf).
- **Period:** 1 July 2026 to 30 June 2027.
- **Why there is no preset:** The ICRC decision is a **2.73%** maximum average change to ActewAGL’s *basket* of standing offer tariffs, plus estimated annual bills at assumed usage. It does **not** publish a single residential c/kWh usage rate. No usage rate was derived from the annual bill figures (those include a supply charge and an assumed 6,500 kWh). The ACT preset is therefore **blank**; enter a rate from a bill or from the retailer’s published schedule.
