Company spokesman Olivia Koch told CNN the incident took place in Gleannloch Farms, near Spring, Texas.
According to a posting to Twitter Investigators were called in by the Harris County Fire Marshal’s Office for “a possible gas explosion and fire,” and based on initial reports, it appeared that crews working in the area struck a natural gas line.
Officials evacuated residents from the area and set up a 150-foot perimeter around the scene, according to another HCFMO post.
In addition to the injured, at least one house was damaged by the fire, according to the marshal’s office.
Electrical service was also interrupted for about 800 customers in the area due to damage to certain electrical equipment, Centerpoint’s Koch said.
CenterPoint Energy crews will begin repairs to restore service to both natural gas and electric customers affected by the incident once the site is safe, she added.
