  Constellation Announces First Integrated Competitive Electricity Supply and
  Load Response Offering

Constellation Peak Response allows commercial and industrial customers to cut
capacity and transmission costs by reducing electricity usage during peak grid

Business Wire

BALTIMORE -- January 28, 2013

Constellation, a business unit of Exelon, today announced the launch of
Constellation Peak Response, a program which allows Constellation commercial
and industrial (C&I) electricity supply customers to reduce future capacity
and transmission costs by lowering electricity consumption during the hours of
peak demand.

Capacity and transmission charges vary by region and typically account for 20
percent to 30 percent of a C&I customer’s overall electricity bill. Capacity
charges ensure that there is an adequate excess supply of electricity to meet
the highest levels of grid demand, while transmission charges cover the cost
of transmitting energy over the grid from a generating facility to local
utility distribution facilities. In most regions, these charges are based on
several hours each year when the grid is at its highest level of demand.

Constellation Peak Response leverages the company’s wholesale market expertise
to predict the peak grid hours and sends day-ahead and day-of notifications,
alerting customers to reduce electricity consumption. The benefit to customers
is realized the following year when the regional grid operators and local
utilities determine the customer’s share of capacity and transmission charges
based on electricity consumed during peak grid hours.

Participation in the Constellation Peak Response program is voluntary and,
unlike traditional load response programs, there is no penalty for failure to
comply when a load response event occurs, providing a low-risk opportunity for
customers to save on their overall electricity costs.

“We are continually looking for new ways to provide a more comprehensive
energy portfolio management strategy for our customers,” said Gary Fromer,
senior vice president, energy management programs, for Constellation. “With
Constellation Peak Response, customers now have the opportunity to take
advantage of a voluntary, flexible load response program that targets what
matters most: their utility bills.”

Constellation Peak Response offers customers two payment options -- saving on
their Constellation monthly bill or receiving a quarterly check -- during the
year following their participation in the program. Since the program’s pilot
began in April 2011, more than 100 customers have enrolled a total of 400
megawatts into the program. In 2012, these pilot customers received more than
$500,000 in Peak Response payments and savings as a result of their lower
electricity consumption during Constellation Peak Response alert hours.

The Constellation Peak Response program is currently available to
Constellation commercial and industrial power customers in the PJM, New
England, New York and ERCOT regions. For more information please visit
