Exelon Generation replaced all 96 emergency warning sirens in the
10-mile radius around Three Mile Island with new, state-of-the-art units
featuring battery back-up power. The siren replacement project began in
October 2011 with the new system placed in service in September 2013.
The Three Mile Island siren investment is part of Exelon Generation’s
commitment to replace and upgrade the emergency sirens at all of its
sites in the mid-Atlantic, including Limerick Generating Station, Peach
Bottom Generating Station and Oyster Creek Generating Station. This
project involves a total investment of more than $11 million and the
replacement of 400 sirens.
The continuous 3-minute tone alerts our neighbors to tune to an
Emergency Alert Broadcast Station for information from Pennsylvania
