Plan types explained
- Single rate — one price per kWh at any time of day.
- Time of use — the price per kWh changes by time of day: peak (afternoon/evening) costs more than off-peak/overnight.
- CL (controlled load) — a separate, cheaper circuit for an appliance like electric hot water, billed at a lower rate.
- Demand tariff — an extra charge based on your highest power use during peak times, so your cost depends on your peak usage.
- Market price — the rate tracks the wholesale electricity market, so it can change.
