This bill amends federal utility regulations to prevent electric companies from cutting off service to customers during extreme heat or extreme cold weather events. The legislation applies to both regulated electric utilities and non-regulated utilities, protecting consumers from losing power during dangerous weather conditions that could threaten their health or lives. The bill requires state regulatory authorities and utilities to define what qualifies as extreme weather events in their areas, and utilities retain the ability to temporarily suspend service to specific areas when necessary for infrastructure safety and maintenance. The law also mandates that utilities update their termination procedures at least every ten years to account for changing climate conditions based on the best available science. The bill additionally ensures that procedures include reasonable protections for elderly consumers and those with disabilities.
