Power outages are the clearest signal of grid stress — and the strongest case for battery storage. This is the resilience view behind the Stromfee BESS optimizer. We are onboarding live US outage telemetry; until each feed is verified, we show only confirmed data and are upfront about what is not yet live.
Real-time US grid-health monitoring — grid frequency, regional outage feeds and live outage counts — is being integrated and is not live yet. Rather than display estimated or placeholder figures, we are holding back outage numbers until each source is verified against its operator. You will never see invented outage counts or fabricated “customers affected” figures on this page. The sections below show what is confirmed today and what is in the pipeline.
The lower-48 US grid runs as three largely separate AC interconnections — the Eastern Interconnection, the Western Interconnection, and the Texas grid (ERCOT). A blackout in one rarely spreads to another because the ties between them are limited.
NERC sets and enforces reliability standards. Day-to-day, independent system operators (ISOs) and regional transmission organizations (RTOs) balance supply and demand and keep frequency near 60 Hz across most of the country.
Most large US outages trace back to extreme weather — winter storms, heat waves, hurricanes and wildfires — stressing generation and transmission at the same time. Equipment faults, fuel constraints and, increasingly, physical and cyber threats add to the risk.
A battery can pick up load instantly when the grid drops, bridging the gap until backup generation starts or the grid recovers. For a site, that is the difference between a flicker and a full shutdown.
Batteries respond in milliseconds to frequency deviations, injecting or absorbing power to keep the grid in balance. Fast frequency response from storage is one of the cheapest ways to make a high-renewables grid stable.
The same battery that earns money charging on cheap (often negative) prices and discharging at peak also stands ready as backup power. The Stromfee optimizer schedules both — value every day, resilience when it counts.
