Duke Energy and county officials to test sirens around Oconee Nuclear Station

The 65 outdoor warning sirens around Oconee Nuclear Station will be tested for three minutes between 11 a.m. and 1 p.m. on Wednesday, Oct. 8, 2025, as scheduled. To ensure they are functioning properly, it may be necessary to test some sirens more than once. Follow-up testing after siren maintenance may be required after 1 p.m.

Testing is performed in cooperation with emergency management officials in Oconee and Pickens counties, who are responsible for sounding the sirens. Since this is a test, local broadcasting stations will not interrupt regular programming to broadcast Emergency Alert System (EAS) messages.

If there was ever a real emergency at the plant requiring the sirens to be sounded, local radio and television stations would broadcast information and instructions to the public.
