The numbers that decide your Sumo Energy bill

Usage rate (c / kWh)

What you pay for every unit of electricity you use. The single biggest driver of your bill if you use a lot of power.

Daily supply charge (c / day)

A fixed fee you pay every day just to be connected, regardless of how much energy you use. It adds up across the year.

Peak vs off-peak

Time-of-use plans charge more at peak times and less off-peak. They suit homes that can shift usage to evenings, nights or weekends.

Sumo Energy electricity rates last verified June 2026 from the retailer's published rate documents (these plans are not currently in our live feed). Figures are GST-inclusive, in cents; your exact rate depends on your address, network, meter type and usage. Open each plan's price breakdown for the full per-network detail. Always confirm the plan's Basic Plan Information document and compare against the reference price before signing up.
