"Pacific Gas & Electric has requested us to respond, and our guys have stepped up and answered the call," said Tony Tewelis from Arizona Public Service.
Linemen from APS are headed to California after powerful storms there caused major flooding and sinkholes and toppled power lines. Thousands are without power.
"Our first stop is Fresno, California to restore distribution and commercial power and move on to Sacramento," said lineman Troy Hall.

More than 40 crew members from APS are suiting up and heading out.
"We went to storm Sandy in New York. I've been to California before on fires, and we went to Florida once before," Hall said.
Since APS partners with 50 other utility companies, it's their duty to respond to Pacific Gas & Electric's call for help.
"Help each other out in the response of a natural disaster, a major storm response, or a critical system event," Tewelis said.
Their first order of business once in California is to head to areas that need restoration first. But they won't be gone too long.
"Right now, we're anticipating a week so they should be coming back Friday or Saturday, depending on the damage and future weather patterns," Tewelis said.
"It's rewarding," said Hall. "It's a good feeling."
