What this means
The grid is run by the state's ISO/RTO (e.g. ERCOT in Texas, CAISO in California, NYISO in New York, PJM across the mid-Atlantic, MISO across the Midwest). Investor-owned and municipal utilities buy power from that wholesale market and deliver it to homes. Peak demand happens on hot summer afternoons (cooling load) and cold mornings (heating + lighting).
What you can do
- Report outages and track restoration through your state's major retail utilities.
- During a multi-hour outage, keep refrigerator/freezer closed (4 hr full / 48 hr full freezer holds safe temps).
- If you depend on medical equipment, register with your utility for priority restoration.
- On hot peak days, set thermostat to 78°F+ and run major appliances overnight to reduce grid stress.
