Exelon's Braidwood-1 nuclear unit in Illinois at 100% capacity after output cut

Exelon Generation's 1,320-MW Braidwood-1 nuclear unit in Braceville, Illinois, was operating at 100% capacity Tuesday afternoon after reducing output Monday due to grid constraints, a company spokeswoman said.

Output at the unit was reduced starting at 6:22 am CDT (1122 GMT) Monday in coordination with regional transmission operator PJM Interconnection "due to transmission line constraints," Exelon spokeswoman Peggy Warnick said Tuesday in an email.

Braidwood-1 returned to 100% capacity at 10:03 am CDT (1503 GMT) Tuesday, Warnick said.



Earlier Tuesday morning, Braidwood-1 was operating at 90%, down from 100% early Monday morning, the US Nuclear Regulatory Commission said in its daily reactor status report.

The adjacent 1,295-MW Braidwood-2 was operating at 100% Monday and Tuesday, according to NRC reports.

Since 2015, Exelon has temporarily reduced off-peak output at one or more of its nuclear plants in Illinois numerous times because of grid constraints and what the company calls "pricing signals."

Exelon has previously said intermittent grid congestion has been occurring in the region around those plants because of transmission line outages for scheduled maintenance, large influxes of wind-generated power into the grid during off-peak hours, or a combination of those factors.
