A winter storm and snowfall prompts a power emergency in Texas, a day after the cancellation of flights and affected the traffics.

Electric Reliability Council of Texas, which manages the flow of electricity in the state, has urged residents to reduce the use of electricity use. The Council started a rotation of power outages, since the early morning.

"Energy conservation is critical. Rotating outages are underway to reduce demand on the electric system. We urge Texans to put safety first during this time. Traffic lights and other infrastructure may be temporary without power," the council informed via its Twitter.

The council described the rotating outages as a “last resort to preserve the reliability of the electric system as a whole". It also added that utility transmission companies have been tasked to determine how to reduce demand on the system.

“Every grid operator and every electric company is fighting to restore power right now,” Ercot president and chief executive Bill Magness said in a statement.

The power outage is expected to last throughout Monday morning.
