ComEd’s Smart Grid and Upgrades Improve Reliability and Help Ensure Power System is Ready to Serve Customers this Winter

Customers are encouraged to take advantage of winter energy efficiency tips
CHICAGO (November 3, 2016) – As temperatures begin to dip, ComEd has been hard at work to ensure the company’s electric systems is ready to meet the energy needs of customers all winter long.
Throughout 2016, ComEd has continued its work to create an advanced energy delivery system, improving reliability and building smart infrastructure for the future. From 2012 through September of this year, more than 7.3 million customer interruptions have been avoided, thanks in part to ComEd’s work to modernize the grid. Installation of advanced technology including more than 230 smart switches that reroute power around problem areas and tree resistant cables that storm harden the system have contributed to more than 1.5 million avoided power interruptions in 2016 alone.
ComEd’s grid modernization work resulted in Illinois’ recent ranking of 2nd nationally in the 2015 Grid Modernization Index, a national report produced by the GridWise® Alliance and the Smart Grid Policy Center.
“The work we’ve done to modernize the electric grid is essential to meeting the increased electricity needs of our customers during the coldest months of the year,” said Terrence R. Donnelly, executive vice-president and COO. “This work begins months in advance and helps us meet the increased demand for energy, when our customers need it the most.”
ComEd also encourages customers to take advantage of the following no costs/low costs tips to help safely prepare their homes for winter weather, manage their energy usage and reduce electricity costs.
Set your thermostat up back to 10 degrees lower during the winter, when you leave your home and before going to sleep. You could save up to 10 percent a year on heating 
Check your HVAC filter every month. If the filter looks dirty after a month, change it.  A dirty filter will slow down air flow and make the system work harder to keep you warm thus wasting energy. 
Replace conventional incandescent holiday lights with LEDs (lighting emitting diode). LEDs typically consume about 75% less and can last up to 10 times longer.  They’re also more durable, shock-resistant and generate less heat compared to traditional incandescent light strands
Inspect the caulking and weather-stripping around all windows, doors and openings for utility services, replacing as necessary. Also, check ducts that move air to-and-from a forced air furnace, central air conditioner, or heat pump, which are often big energy wasters. ComEd offers a rebate program for several weatherization products. Go to for more information.
