Home Energy Load Planner
Build an appliance schedule and separate daily energy from connected running power.
Open this toolDaily electricity use and connected appliance power answer different planning questions. A fan running for several hours uses energy over time.
Build a schedule using quantities, running watts and operating hours. Use duty factors for appliances that cycle rather than treating them as continuously active.

How to use
- Add the entries in appliance schedule as separate rows. Include appliance, quantity, running power per unit, daily operating time and duty factor for each row.
- Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why use this tool
The schedule keeps watts and daily energy separate, useful when checking a household's solar and backup requirements.
Before relying on the result
Duty factor scales energy, not connected power. This schedule does not predict simultaneous demand or motor starting power.
Tool limitations
Duty factor scales energy, not connected power. This schedule does not predict simultaneous demand or motor starting power.
Questions
Does connected power predict simultaneous demand?
No. It is the sum of listed running loads. Actual overlap and motor starting demand need separate assessment.
What should I check before using Home Energy Load Planner?
Check Appliance, Quantity, Running power per unit and Daily operating time. Use the exact units shown beside the controls and replace any example values with your own inputs.
