ComEd Rebuilding Transmission System in Tornado-Ravaged Areas

June 10, 2010 — ComEd began a massive construction effort to rebuild its transmission system in the Streator and Dwight areas after a tornado Saturday inflicted the most significant damage on the utility’s system in six years.
 
The company restored all of the nearly 20,000 customers affected by this storm system early Tuesday morning. This includes 8,400 customers directly affected by the tornado, but work to rebuild the transmission system is expected to last multiple weeks. It will include restringing 34 miles of transmission line, replacing six twisted transmission towers and making significant repairs to a seventh tower.
 
The extensive destruction in and around Dwight and Streator included uprooted trees, broken poles, and damage to seven transmission towers and two distribution substations that served large portions of the area. More than 100 crews came from as far away a Rockford and Libertyville to work around the clock to replace about 120 poles and 25 miles of overhead power line, and restore all customers to service. However, complex repairs to the transmission towers will require weeks to complete given the severity of the damage and importance of these lines in carrying electricity to millions of customers throughout Illinois and beyond.
