​LONDONDERRY TWP, PA  — Exelon Generation will conduct its semi-annual, full volume test of the emergency warning sirens surrounding Three Mile Island Generating Station on Thursday, Dec. 3 at approximately 12:15 p.m. This is one of two semi-annual tests performed each year.

The TMI emergency warning siren system consists of 96 sirens located in parts of Cumberland, Dauphin, Lancaster, Lebanon and York counties that are located within a 10-mile radius of TMI. The purpose of the sirens is to alert residents to tune to an Emergency Alert Broadcast Station for information from Pennsylvania state officials. During the test the Emergency Alert Broadcast System will not be activated.

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