Texas City was under a Level 1 emergency. There were some road blocks put in place around the plants during the power outage.
The power is back on and the plants are returning to normal operations.
"Generally they are on the same circuit. There are different circuits certainly because there is an awful a lot of power involved," said Bruce Clawson with the Texas City Office of Emergency Management. "But generally when it occurs on one, it occurs on all of them. That is what happened to the city. It tripped one substation and it began to trip other substations and they had to bring them back up and reverse auto."
The power company says the preliminary report is that the damp conditions this morning may have mixed with residue, possibly causing the outage.
This is the second outage in the area in the last month. Back at the end of April, a power outage affected three refineries and a chemical plant in Texas City.
