At 8:30 a.m., more than 111 outages affecting approximately 26,000 customers were reported, and CPS crews are working to restore power, according to the release.
As of 1 p.m., approximately 14,000 customers are still experiencing outages.
Ice accumulation on trees and power lines is expected to continue, and the weight of the ice can lead to pole fires and downed lines.
Downed lines are to be treated as live, and customers should not attempt to move or drive over the lines.
According to CPS, outages are likely to occur throughout the day and possibly into the morning of Feb. 2 before temperatures begin to rise in the afternoon.
Customers are encouraged to conserve energy by lowering the thermostat to 68 degrees, with additional conservation tips here.
To report a downed line or outage, contact CPS at 210-353-4357. Information regarding current outages can be found on the CPS Energy website.
