Three Mile Island Emergency Siren Test Scheduled for Dec. 5
Sirens to Sound for Three Minutes at 12:15 p.m. EST
 
LONDONDERRY TWP., PA (December 3, 2013) – Exelon Generation will conduct its semi-annual, full volume test of the new emergency warning sirens on Thursday, Dec. 5 at 12:15 p.m. EST.  With the installation of the new siren system, TMI is moving to a semi-annual full volume test schedule.  The next test will be held during the first week of June 2014. 

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 state officials.

Three Mile Island Generating Station is located approximately 12 miles south of Harrisburg.  The plant generates enough carbon-free electricity for 800,000 homes.
