Billing
How we calculated this
- Usage is the daily kWh times the days in the bill times the usage rate.
- The supply charge is a fixed amount for every day of the bill.
- Off-peak hot water is added and the solar export credit is taken off. All rates include GST.

Usage
17.4 kWh a day (AER benchmark) × 91 days × 33.14c/kWh = $524.69
Supply charge
91 days × 166.23c = $151.27
Off-peak hot water and solar
Controlled load kWh × days × its own rate, less solar exports × days × the feed-in tariff. Both are 0 unless you add them under Advanced settings.

Controlled load 1 (EA030) on Ausgrid
Controlled load 1 (EA030) on Ausgrid: 19.12c a kWh from 1 July 2026. Supply hours: at least 6 hours a day. Controlled load 2 on Ausgrid is 22.77c a kWh, with supply for at least 16 hours a day. Controlled load 1 is 20.44c a kWh on Endeavour Energy and 19.69c on Essential Energy. These three are also one retailer’s prices (Nectr). EA030 is Ausgrid’s network tariff code for controlled load 1.
Source: Nectr’s own standing offer price from 1 Jul 2026 (one retailer, not the regulated price), read on Nectr’s rate update page on 1 Oct 2026. The regulated cap for 2026-27 differs: 19.3094c for Ausgrid controlled load 1 and 23.0050c for controlled load 2 (AER DMO 2026-27 determination, s.9 table (5)) (Dated third-party source). Checked 1 October 2026.
The calculator on this page uses that rate for off-peak hot water on Ausgrid and Endeavour Energy. It is 14.02c a kWh under the Ausgrid general rate at the default offer price (33.14c, Official source). Each kWh a day of hot water on controlled load, not on the general rate, takes $13 off a quarterly bill on Ausgrid at those two rates. On Endeavour Energy type the controlled load rate from your own bill.
