Everyone can agree that losing power is an unwelcome disruption. Life is less comfortable when you can’t watch TV and there’s no hot water for a warm shower. But if you are a vulnerable customer, a loss of power can be more than just an inconvenience. You may not have the money to replace the groceries that spoil during a lengthy outage. Or you may face a serious medical crisis if you rely on electricity to keep a heart monitor or oxygen machine operating.
