On top of dealing with the cold weather, many people were worried about flares that turned the sky orange.
Petrochemical facilities were also experiencing a power outage causing them to shut down units, thus the flares for safety. The good news is, power is back on now.
Texas City emergency management says, they aren't sure what caused the unplanned outages.
ABC13 reached out to ERCOT for more information. The company sent the following statement:
"We are aware of an outage issue involving a Texas-New Mexico Power (TNMP) transmission line. We are talking with TNMP and offering any assistance we can provide. This transmission outage does not impact overall grid reliability."
TNMP said they're looking into what caused their equipment to fail.
About 20,000 of their customers were left without electricity in Texas City and La Marque.
