For those who live within a 10-mile radius of our VC Summer Nuclear Station, our alert sirens will soon be replaced with wireless emergency alerts that will come to your cell phone. These alerts, identical in nature to Amber and Severe Weather alerts, have a number of advantages over the sirens. Not only do these alerts have the ability to offer real-time information in the event of an emergency, as opposed to a noise alone, the system itself was designed by the Federal Emergency Management Agency (FEMA) for exactly this purpose. If you have any questions that aren’t answered below, please visit to learn even more.

Frequently Asked Questions

The anticipated transition date is December 21, 2021.

Prior to the December 21, 2021 transition date, both the sirens and the wireless emergency alert system are available to warn you in the event of an emergency.


Dominion Energy, in partnership with South Carolina Emergency Management, is making this change to utilize current technology to better protect the health and safety of the public. This change will allow us to provide information on a real-time basis on what actions to take in the event of an emergency.


FEMA implemented wireless emergency alerts in 2012. Today, there are more than 1,500 federal, state, local, tribal, and territorial alerting authorities that use this system to send critical public alerts and warnings in their jurisdictions. It has been used nearly 56,000 times to warn the public about dangerous weather, missing children, and other critical situations.
  • Unlike the alert sirens which just make a noise, wireless emergency alerts sent to your cell phone provide information on what to do and what actions to take in an emergency. This means you will know exactly what to do if an emergency happens at the VC Summer Nuclear Stations.
  • Wireless emergency alerts allow for follow up messages and updates to be sent out regarding an emergency. This means you will get updates and further guidance throughout an emergency.
  • Sirens are not designed to always be heard indoors, whereas wireless emergency alerts can reach you inside your home, at work, in the car, or wherever you are near a cell phone.
  • The alert sirens are only sounded for a total of approximately fifteen minutes. The wireless emergency alerts allow a much longer window of time for you to receive the alert. This means anyone traveling within a ten‐mile radius of VC Summer Nuclear Stations during the alerting window will receive the alert message on their cell phone, where they would likely not have heard the sirens going off.
  • The wireless emergency alert system uses GPS targeting, meaning that the wireless emergency alert will go out to anyone and everyone who is within a ten‐mile radius of the VC Summer Nuclear Stations, whether they live, work, or are vacationing in the area.

Devices capable of receiving Wireless Emergency Alerts are marked on the retail callout card and at the manufacturer equipment descriptions online with the Wireless Emergency Alert Capable logo:
