What’s happening: The power company said on Wednesday that the Arizona Department of Public Safety had issued a power outage warning.
It is the first time in nearly a decade that an outage has been issued to the state.
The Arizona Department has been ordered to restore power to all customers in the state as of 1 p.m.
Thursday, according to the power company.
The outage was caused by a failure in an aging transformer that was not properly maintained and had been out of service for weeks, the utility said in a statement.
The outage occurred around 6 p.d. on Monday, the same day a fire broke out in an electric substation in the northern Arizona city of Prescott.
The transformer was rated for 100,000 kilowatts of power, but the voltage and frequency of the power supply was set to about 50,000, according the utility.
The transformer is expected to be fixed.
