Power outages throughout Southern Maryland

Update from SMECO:

Shortly before 1 p.m. a Pepco 230-kilovolt (kV) transmission conductor located at SMECO's Ryceville switching station in Charles County broke free from its support structure and fell to the ground. This failure resulted in the loss of supply to SMECO’s Ryceville and Hewitt Road stations. The Pepco supply to the Morgantown and Chalk Point interconnect locations was also interrupted.

No SMECO equipment was damaged and all protective devices operated correctly to isolate SMECO equipment from the Pepco fault.

SMECO has rerouted power through our 230-kV system in Calvert and St. Mary's County to restore service. All SMECO customers affected by this event were restored by 2 p.m.

Report from Exelon

Calvert Cliffs SHUTS DOWN Automatically Due to
offsite grid disturbance

LUSBY, MD  - Calvert Cliffs Nuclear Power Plant shut down automatically Tuesday, April 7 at 12:40 p.m., as a result of a localized grid disturbance that caused power outages in the Washington, D.C./Maryland area.

Calvert Cliffs is designed to shut down automatically during significant electrical disturbances. The plant shut down safely and without incident. Both reactors will remain in “hot shut-down,” which means the reactor remains ready to resume power production, until the offsite grid disturbance can be addressed.


Update:

According to reports the generating plant at Chalk Point is connected to a substation on Ryceville Road in Charles County. The insulator from this line failed and released the power line that connects to the substation which caught on fire when it hit the ground. Reports say the explosion was over 100 feet tall. No injuries have been reported.

SMECO lineman, Kevin Thomas, told The BayNet PEPCO and SMECO are jointly investigating the explosion, there is no estimate as to how long it will take to repair the substation. The utility companies are in the process of switching the power as a work-around. When asked why this substation was causing such a large outage Thomas said that this transmission line goes over the entire United States.

Power is beginning to be restored throughout the area.


Update:
Power outages may be linked to a switching station located in Charles County on Ryceville Road. Reports are also being made that 13 metro stations are without power.

There have been reported power outages across the entire Southern Maryland area.

Traffic lights out throughout Southern Maryland - treat intersections as a 4 WAY STOP & PROCEED WITH CAUTION.
