PowerUp Enables Electrification on 100 Amp Service

Company Report
PowerUp allows a homeowner to install an EV charger, heat pump, electric range, and water heater on a 100-amp service that would traditionally be undersized for simultaneous use.

PowerUp turns panel capacity into software, which lets SPAN sell electrification without forcing the homeowner to buy a bigger utility connection first. Instead of sizing the home for every appliance running flat out at once, SPAN watches whole home load in real time and briefly slows flexible loads like EV charging or a tank water heater. That makes a 100 amp service workable for more all electric upgrades and removes one of the biggest cost and schedule blockers in retrofit and new build jobs.

  • The economic point is avoiding the service upgrade, not just adding app control. In new construction, specifying SPAN can avoid 400 amp service in some homes, with estimated savings of $5,000 to $12,000 per site. In retrofit, it can avoid utility work, trenching, and long approval timelines that often cost more than the panel itself.
  • PowerUp works because not every large load is equally time sensitive. A car can charge a bit slower overnight, and a tank water heater can pause briefly because it stores hot water. SPAN uses that flexibility first, and homeowners can rank circuits in the app so comfort and must run loads stay ahead of deferrable ones.
  • This also shows where SPAN sits versus alternatives. Battery makers like Tesla and Enphase can shed loads as part of a storage system, while simpler load controllers solve a narrower problem for one or two appliances. SPAN is the higher priced option, but it combines panel replacement, circuit level sensing, app control, backup configuration, and service limit management in one box.

The next step is from avoiding panel upgrades one home at a time to making constrained electrical service normal in all electric homes. As more builders, HVAC installers, and EV charger installers sell around the same bottleneck, the winning products will be the ones that make limited amperage feel invisible and turn electrification into a software managed workflow instead of a utility construction project.
