Almost 30 percent drop in electricity supply charges means all customers can
benefit from lower energy prices

CHICAGO, March 29, 2013

CHICAGO, March 29, 2013 /PRNewswire/ -- ComEd today filed with the Illinois
Commerce Commission its annual update of electricity supply charges, the
primary component of the "Price to Compare," which will take effect in June
2013. The average residential electricity supply charge for customers who buy
energy from ComEd will drop from approximately $.07/kilowatt-hour to
approximately $.05/kilowatt-hour, a reduction of almost 30 percent, as a
result of lower energy prices. Customers that have switched to alternative
suppliers for their electricity supply have likely been realizing lower costs
already.

As a result of Illinois' longstanding policy to bring electricity choice to
consumers, ComEd customers can use the Price to Compare to evaluate offers
from alternative retail electricity suppliers. About 75 percent of ComEd
customers already have switched to an alternative supplier for their
electricity supply. And choices are abundant: More than 40 alternative
suppliers in ComEd's service territory are certified to sell electricity
supply to residential customers, and more information is available at
www.pluginillinois.org.

"We know that customers are most concerned with their total bill each month,"
said Anne Pramaggiore, president and CEO, ComEd. "Whether customers get their
electric supply from ComEd or from an alternate supplier, they are saving
money as a result of lower energy prices."

The Price to Compare is determined using expected electricity supply and
transmission charges and makes up about two-thirds of the average residential
customer bill. In May 2013, ComEd will file new transmission rates to take
effect in June 2013. Transmission costs are expected to increase as a result
of service-enhancing investments and are reflected in ComEd's Price to
Compare.

The other one-third of the bill is made up of delivery charges. Under the
Smart Grid law, delivery charges are updated every year in January. In the
next few weeks, ComEd will file its proposal for its new delivery charges to
take effect Jan. 1, 2014. Under this proposal, delivery charges are expected
to increase as a result of grid modernization and other service-enhancing
investments, but the increase is largely offset by lower energy prices.

"Even with these changes, for the next year ComEd customers' bills are
expected to be the same or lower than they were a year earlier, because of
lower power prices," said Pramaggiore. "And because energy prices are low,
this is the ideal time to invest in grid modernization."

Commonwealth Edison Company (ComEd) is a unit of Chicago-based Exelon
Corporation (NYSE: EXC), the nation's leading competitive energy provider,
with approximately 6.6 million customers. ComEd provides service to
approximately 3.8 million customers across northern Illinois, or 70 percent of
the state's population.
