Free all-electric readiness check for building electrification, heat pump, EV load, and gas removal planning.
What is an all-electric readiness check?
An all-electric readiness check estimates whether a building has enough spare electrical capacity for heat pumps, electric hot water, EV charging, and removal of gas-fired loads. It converts heating load into likely heat pump electrical input using COP, adds other electric loads, applies diversity, and compares the result with available spare capacity. Engineers, owners, and retrofit teams use it during electrification planning before starting detailed transformer, switchgear, utility, or heat pump studies. It helps identify whether the project is probably simple, constrained, or likely to need an electrical upgrade. The result is a screening check only. Final design must verify load profiles, maximum demand, utility supply, switchgear ratings, cable routes, protection, standby strategy, controls, and local regulations. For best results, keep the entered units consistent, load the sample first, then adjust one assumption at a time so the result can be reviewed and explained.

How this tool helps
Use this to screen electrification readiness before detailed electrical studies, transformer checks, utility applications, or heat pump design.
Calculation methodology
Gas heating load is converted to equivalent heat pump electrical input using COP. Hot water and EV loads are added with diversity, then compared with spare capacity.

Input definitions and typical values
These notes explain what each input means and which values usually produce a more reliable planning result.
Available spare electrical capacity kW
Available spare electrical capacity. Confirm with transformer, generator, switchgear, cable, and utility limits.
Gas heating load to replace kW
Gas heating load to replace. Convert to heat-pump input using expected COP, not 1:1 electrical replacement.
Expected heat pump COP
Heat pump coefficient of performance. Typical planning values often sit around 2.5-4.0 depending climate and system.
Electric hot water load kW
Electric hot water load. Include diversity and storage strategy for realistic all-electric planning.
EV charging allowance kW
EV charging allowance. Use charger rating, simultaneity, and future adoption target.
Diversity factor %
Percentage of connected load expected to operate at the same time. Use project schedules; 60-90% is common in many planning checks.
Practical verification checklist
- Confirm the selected standard profile is suitable for the project location and authority.
- Replace sample values with project drawings, schedules, equipment data, or measured site values.
- Review warnings, methodology, and PDF report before using the result outside early planning.
- Verify final decisions against official standards, manufacturer data, consultant specifications, and local approvals.
