Many can’t
Low-income renters can't buy, store fuel for or run one in an apartment; many older patients can't safely start or refuel one.
Protect the patients who can't lose power, before the outage.
OurGrid keeps older patients on home medical devices safe before the power goes out, not after.

911Last resort
Utilities know where the power will go out. Agencies know who's on oxygen. OurGrid connects them before the outage.
Why not a generator?
Backup that's safe to use at home.
Generators kill
About 85 carbon monoxide deaths a year in the U.S. (CPSC).
OurGrid instead
OurGrid makes sure existing backup is charged and in the right home.
Dual use
Useful every day, ready for the worst.
Everyday + emergency
Keeps batteries charged and emergency plans current every day, then switches to triage in a crisis.
Civilian + government
The same engine works for heat waves, wildfires, hurricanes and grid attacks; utilities and agencies use it daily, emergency managers in disasters.
Who pays
Utilities and agencies pay. Patients don't.

We don't sell batteries or electricity. Batteries belong to the utility or agency; OurGrid tracks and dispatches them.
