Exelon Corp.'s (EXC.N: Quote, Profile, Research) 1,178-megawatt Unit 1 at the Braidwood nuclear power station in Illinois shut Wednesday likely due to a lightning strike on a power line, a spokeswoman for the plant said Thursday. She said the company was still investigating the cause of the outage but noted there was no damage to plant equipment.
She could not say when the unit would return to service due to competitive reasons. Electricity traders guessed the unit would return within a few days.
The 2,330 MW Braidwood station is located in Braceville in Will County, about 60 miles southwest of Chicago.
There are two units at the station: Unit 1 and the 1,152 MW Unit 2. Both entered service in 1988. Unit 2 continued to operate at full power.)
