EnergyMeterHub Tool Details
Tariff Fit Checker
Helps users compare flat rate and TOU based on evening imports, daytime use, EV timing, and whether a battery already softens the peak period.
Planning
First-party
Check whether flat rate or time-of-use is more likely to fit your home load pattern.
What this tool is for
Who this tool is for
Homes trying to decide whether flat rate or time-of-use is a better behavioral fit before diving into retailer-specific offers.
What this tool is not
It is not a full tariff simulator. It is a direction tool for understanding whether your home behavior naturally fits one tariff structure better than the other.
How to use the output
Use the result to identify the habit driving the answer, such as heavy evening imports or disciplined overnight EV charging, then validate that pattern against a real interval view if you can.
Why this tool is worth using
- Helps users understand whether flat rate or TOU is a more natural fit before comparing retailer plans.
- Surfaces the home behavior driving the tariff answer, such as heavy evening imports or controllable overnight loads.
- Encourages smarter tariff thinking without pretending to replace a full bill simulation.
How to use it well
Think about controllable load timing
The key question is not whether TOU sounds cheaper. It is whether the home really has enough flexible load timing to make that tariff structure work week after week.
Use interval data if you have it
The result becomes much stronger when checked against a smart-meter or interval-data view instead of memory alone.
Examples
Example
A home with heavy evening imports but no repeatable overnight EV charging often leans flat rate even if daytime usage looks reasonable.
What this tool does not replace
Not a full tariff simulator
It does not replace retailer-by-retailer bill modeling, controlled-load analysis, or demand-charge calculations.
How to continue
Open the tool when you know the question you are trying to answer
Use the interactive version once you know what inputs matter and what kind of answer you are expecting from it.
Use the result as guidance, not a final purchase promise
These pages are designed to make the tool easier to use correctly, but you should still validate important hardware, tariff, and compatibility decisions before buying.
