Duke Energy and county officials will test the outdoor warning sirens around the Oconee Nuclear Station between 11 a.m. and 1 p.m. on Wednesday, Oct. 7, 2026.
This is only a test to ensure they are functioning properly, sirens will sound for three minutes. 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 1 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.
Duke Energy owns and maintains a network of sirens within 10 miles of each of its nuclear plants, including 65 sirens around the Oconee Nuclear Station. Testing is performed in cooperation with emergency management officials in Oconee and Pickens counties, who are responsible for sounding the sirens.

Outdoor warning sirens will be tested today, October 7, around all Duke Energy nuclear plants. This testing is part of normal maintenance to make sure they’re working properly and conducted in conjunction with state and county officials. Today’s siren test will be a full-volume test and last for approximately 3 minutes. Some sirens may be tested more than once. Follow-up testing after the regularly scheduled siren maintenance time may be required.
