The short answer
Most cold-climate US states prohibit utility disconnections Nov 15-Mar 31. Texas and Arizona ban disconnects when temperatures exceed 100-105°F. Medical-necessity protection is year-round in every state with doctor documentation. Utilities must give 10-14 day disconnect notice before any disconnect.
US states protect residential utility customers from disconnection during cold-weather months and, in some southern states, during summer heat events. The rules vary by state but the principle is consistent: utilities cannot disconnect electricity or gas service when doing so would create a health or safety risk. This guide walks the state-by-state moratorium calendar.
Cold-weather moratoriums
Most cold-climate US states prohibit utility disconnections during winter. Typical window: November 15 - March 31. States with strong moratoriums: New York, Massachusetts, Pennsylvania, Connecticut, Maine, New Hampshire, Vermont, Wisconsin, Minnesota, Illinois, Michigan, Ohio.
Moratorium triggers: most states use a temperature-based trigger (24-hour forecast below 32°F), some use a calendar-based trigger (Dec 1 - Mar 31), and some combine both.
Income/age-based variations: some states restrict the moratorium to households with elderly residents, infants, or income below a threshold. Others apply universally.
Summer heat protections
Texas, Arizona, Nevada, and a few other warm-climate states extend disconnection protection during heat events. Trigger: forecast temperature exceeding 100-105°F. Duration: typically the heat advisory window plus 24-48 hours after.
These protections are newer than cold-weather moratoriums (most enacted post-2020) and reflect the reality that summer heat can be as lethal as winter cold for vulnerable populations.
Other states (most of them) do not have explicit summer-heat moratoriums but utilities are generally required to follow due-process procedures (notice, payment plan offer) before any disconnect.
Medical-necessity protection
Every US state protects households with documented medical necessity year-round. Medical necessity = a household member depends on electrically-powered medical equipment.
To invoke: get a doctor letter or filled-out state-specific form documenting the medical necessity. Submit to your utility. Renew annually.
With medical-necessity protection, you cannot be disconnected even for non-payment. The liheap-eligibility-application-guide covers the federal assistance program that pairs with medical-necessity status.
- Cold weather: Nov 15 - Mar 31 in most cold-climate states.
- Summer heat: 100-105°F triggers in TX, AZ, NV.
- Medical necessity: year-round in every state with doctor documentation.
- Notice rule: 10-14 day disconnect notice required before any disconnect.
Recap
Bottom line
Every US state with retail electric or gas service has rules protecting customers from disconnection during cold-weather months, and a growing number extend protection during summer heat events. Medical-necessity protection is universal year-round in every state with proper doctor documentation. The rules vary in specifics but the principle is consistent: utilities cannot disconnect when doing so would create a foreseeable health or safety risk.
For households facing potential disconnection, the workflow is: contact the utility to set up a payment plan (most are required to offer one before disconnect), apply for LIHEAP if income-eligible, and invoke medical-necessity protection if applicable. The liheap-eligibility-application-guide and how-to-dispute-electric-bill-charges guides cover the related programs.
