Some Fort Collins homes, especially older ones, have electrical panels that don't have enough spare capacity for a Level 2 charger without an upgrade. This service evaluates the existing panel's capacity and, where needed, installs a larger panel or subpanel so the home can safely support the charger alongside its other electrical loads.

Common Electrical Panel Upgrade for EV Charging situations in Fort Collins

Your panel is rated 100 amps or lower and you're planning an EV charger

Many older homes were built with 100-amp service, which can be tight once a Level 2 charger (which can draw 30-50 amps on its own) is added alongside existing household load — worth a load calculation before assuming the panel can handle it.

This is a common early sign the panel is at or near capacity, not necessarily a fault in the charger itself.

This is a standard, code-driven part of a proper Level 2 install on an older panel — not an upsell on its own, though it's worth understanding what it actually requires before agreeing to it.

Keep in mind: If your panel already has adequate spare capacity, you likely just need charger installation without a panel upgrade -- an electrician can confirm this during the initial assessment.
