Ten fire departments responded to the Exeter Energy plant in Sterling early this morning to battle a fire.
Officials said the fire started around 4 a.m. at the waste tire-fueled power plant located in the Sterling Industrial Park. The fire is now out.
Employees were in the building when the fire broke out, but no injuries are reported.
The facility uses shredded tires as a primary source of energy.
In January, the facility was evacuated on a Friday morning after fire broke out in a hopper located in the boiler room.
