Why compare more than the headline rate
Keep the lowest advertised number in context
The best-looking rate at one usage tier is not always the plan that feels best on a real bill.
Electricity shopping is closer to comparing checkout totals than comparing one sticker price. Your plan, your usage, and the utility delivery charges all shape the final bill, so the best pick is the plan that still works once those pieces come together.
- Usage-tier pricing can look very different at 500, 1,000, and 2,000 kWh.
- Bill credits and minimum-usage rules can make a cheap plan expensive if your usage shifts.
- Delivery charges still come from the utility even when you switch retail providers.
- Fixed, variable, prepaid, and time-of-use plans do not carry the same billing risk.
