Medically fragile woman put in jeopardy

My 81-year-old mother lives in the Lakewood region and is heavily oxygen dependent. On multiple ocassions within the last month, Xcel has turned off power without notice, leading to dangerous situations each time. The most recent occurred while she was asleep, and medical complications were severe. Multiple phone calls with their representatives resulted only in the recommendation to call 911. We were not notified about their medical needs home registration. The other resident in the home has dementia making the situation even that more dire. In one instance, a hotel had to be sought for multiple days, as Xcel would not give any estimation of power restoration. This is an expense, along with additional medical attention required, is extremely burdensome to people trying to age in their homes with fixed incomes. My mother's life is literally on the line.
