The numbers that decide your Diamond 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.

Live Diamond Energy electricity rates pulled from the energy market, last updated 09/10/2026. Figures are in cents, shown as the range across each network for residential and business plans; 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.

All Diamond plans

Everyday Renewable Saver

No lock-in

Diamond's single residential plan, with zero lock-in contract and no exit fees. Available on single-rate or time-of-use tariffs with optional controlled load. Conditional discounts range from 3% to over 13% off the reference price.

Single rate tariff

A flat rate no matter the day or time, for predictable, simple billing.

Time of Use

Rates that change with the time of day, rewarding usage outside peak demand hours.

Controlled Load 1 & 2

Optional lower rates for energy-heavy appliances running on a separate meter.

Rates change often. Published rates date quickly. Compare Diamond against the retailers that supply your address for current pricing.

Solar

Diamond solar: feed-in tariffs & batteries

Diamond offers some of the most attractive green and solar options in the market. The standard solar feed-in tariff pays 7c/kWh for energy exported from your panels, which sits above the market offer in many areas. GridCredits100 lets homes with a solar battery sell electricity back to Diamond at up to $1/kWh when grid demand is very high. Diamond Pure Plus adds 100% accredited GreenPower for an extra 5.5c/kWh, or 50% GreenPower for an extra 2.75c/kWh; it is optional and can be added or removed at any time. Diamond does not sell panels directly but works with third-party retailers to supply solar to Australian homes.
