EV charger load assessment

Follow a few simple steps using your electricity-provider records. The tool will find the highest-use month, day, and one-hour interval, then prepare a preliminary load calculation for contractor review.

Check your service before installing an EV charger

You will need access to your last 12 months of electricity usage. CSV files can fill the tables automatically; PDF, Excel, or screenshots can be attached as supporting evidence.
