Sirens to be tested Jan. 7
Duke Energy and county officials will test the outdoor warning sirens around the Robinson Nuclear Plant between 1 p.m. and 5 p.m. on Wednesday, Jan. 7, 2026.
Why it matters: To ensure they are functioning properly, sirens will sound for five to 30 seconds. Anyone who hears a siren during scheduled testing does not need to take action.
• During testing, some sirens may be tested more than once. Follow-up testing after siren maintenance may be required after 5 p.m.
• Because this is a test, local broadcasting stations will not interrupt regular programming to broadcast Emergency Alert System (EAS) messages. If there was a real emergency requiring the sirens to be sounded, local radio and television stations would broadcast information to the public.
By the numbers: Duke Energy owns and maintains a network of sirens within 10 miles of each of its nuclear plants, including 59 sirens around the Robinson Nuclear Plant.
Emergency partners: Testing is performed in cooperation with emergency management officials in Chesterfield, Darlington and Lee counties, who are responsible for sounding the sirens.
