Understand the code on your electricity bill.

This is a guide so you can see what your charges are — and how solar and a battery can help. Find the code on your bill, match it to a group below, and open it for the detail.

Endeavour Energy is your distributor— the company that owns the power lines in your area. You don’t pay them directly: your retailer (AGL, Origin, EnergyAustralia, Alinta) sends the bill and passes these charges on.

Western Sydney, the Blue Mountains, Southern Highlands and the Illawarra.

Four kinds of charge. That’s the whole game.

Every tariff below is just a different mix of these. Learn the four once and every code on your bill makes sense.

Daily access

A fixed fee per day, whatever you use. Nothing you do changes it.

Energy

What you pay per unit (kWh). Most tariffs charge more at peak times and less overnight and through the middle of the day.

Demand

Based on your single highest half-hour of use. Most networks measure it each billing month; Ausgrid’s capacity tariffs use your highest half-hour in the rolling last 12 months, so one spike can set a year of charges. It’s the charge a battery is best at cutting. Demand charges, explained

Export

Money for solar you send back to the grid — or a charge if you export at the wrong time of day.

Units, once: kWh is how much you used in total; kW is how hard you pulled at one instant. Demand charges watch the second one. kVAis apparent power — your real kW plus reactive power that does no useful work but still loads the network. Bigger tariffs bill on kVA, so poor power factor raises the bill even at the same kW.

Where a $5,000 quarter actually goes.

One bar, one typical bill. The network slices below come straight from the published 2026–27 rates on Endeavour Energy’s standard small-business tariff (N91). Everything else is your retailer.

  • $2,442Network energy 49%
  • $90Network daily access 2%
  • $2,013Retailer energy, green schemes & market fees 40%
  • $455GST 9%

Assumes about 18,000 kWh over the quarter (roughly $5,000 all-in) on N91, with two-thirds of the usage outside peak, a fifth of it inside the cheap solar-soak window. Illustrative, not a quote — your split moves with your retailer, your usage shape and the exact tariff assignment.

The tariffs, in groups.

Most of the codes are variations on a handful of themes. Find your group, then open your code for the detail.

Prices are the published 2026–27 network rates for the group’s codes, rounded — exact figures and GST treatment are on each code’s page.

Small business — under 160 MWh a year

Most Endeavour Energy small businesses: workshops, shops, small warehouses.

  • Time-of-use energy5.7c–27.7c per kWh
  • Peak demand charge (N92/N93 only)13.1c–26.6c per kW per day

Solar & battery

Solar cuts your daytime units, which are the dearer ones. A battery matters most on N92 and N93, where flattening your peak also cuts the demand charge.

Large business — over 160 MWh a year

Bigger low-voltage sites: factories, cold stores, large facilities.

  • kVA demand charge (highest half-hour, 4–8pm business days)53.2c–58.4c per kVA per day

Solar & battery

Solar trims daytime energy. A battery can shave the kVA peak, but the peak runs to 8pm — keep charge in reserve — and poor power factor needs fixing first.

Embedded network parent

Solar export

Any site sending solar back to the grid — it sits beside your import tariff, not instead of it.

  • Export reward or charge, by time of day3.8c–12.9c earned per kWh exported · 2.0c charged per kWh exported

Solar & battery

This decides what your exported solar is worth. A battery can hold midday solar and send it back in the rewarded window.

Battery-only connection

A standalone battery with its own grid connection — not a normal business meter.

  • Specialist connection charges

Solar & battery

A specialist connection project: the design and the market contract decide the return, not this page.
