Resilience

Battery percentage is not a resilience plan.

A useful home energy resilience score should estimate whether the home can keep essential loads, comfort and safety online when the grid is unreliable.

Short answer: resilience is a forecast, not a number on a battery icon. It combines stored energy, expected generation, essential loads and the home's ability to adapt.

What a resilience score should include

  • Battery state of charge and reserved energy.
  • Critical loads such as refrigeration, networking, lighting and medical needs.
  • Expected weather and solar production.
  • Heating or cooling demand during the risk window.
  • EV battery availability and charging priorities.
  • Confidence level, because forecasts can be wrong.

Why the score must be practical

A resilience score is useful only if it changes behavior. If a storm is expected, the home may pre-charge a battery, pause nonessential loads, change climate strategy or protect a larger reserve. A score that only creates anxiety is not a product feature.

The GridPassport view

GridPassport treats resilience as a north star, not an emergency mode hidden in settings. The system should make the home feel quietly prepared by default.

FAQ

Resilience score questions.

What is an energy resilience score?

An energy resilience score is a way to estimate how prepared a home is to keep essential loads running through grid stress or outage scenarios.

Is resilience score the same as battery state of charge?

No. Battery percentage is only one input. Resilience also depends on essential loads, weather, solar forecast, battery reserve, device priorities and household behavior.

Can a home improve its resilience score automatically?

Yes, in principle. A home energy management system can pre-charge a battery, reduce nonessential loads or adjust climate strategy before a forecasted risk window.
