Key Highlights of 3Q 2012
We
have
optimized

this
volatile
period

are
back

Expect
to
employ
a
variety
of
strategies
to
leverage
ourselves
for
expected
upside
Position our regional portfolios within our Bull/Bear framework to best take advantage of various market anomalies
Further utilize cross-commodity hedges to protect against further downside in the natural gas market, while remaining
open to our view that heat rates will expand
Our forward view continues to be that there is upside in power prices and our
fleet is leveraged for that upside

(1) Stub period calculated by excluding Jan 2012 through mid-March 2012 for Constellation only. (2) Excludes Maryland assets to be divested (3) Includes CENG Joint Venture. (4) Expected
generation represents the amount of energy estimated to be generated or purchased through owned or contracted for capacity.  Expected generation is based upon a simulated dispatch model
that makes assumptions regarding future market conditions, which are calibrated to market quotes for power, fuel, load following products, and options. Expected generation assumes 10
refueling outages in 2012 and 2013 and 11 refueling outages in 2014 and 2015 at Exelon-operated nuclear plants and Salem but excludes CENG.  Expected generation assumes capacity
factors of 92.8%, 93.5%, 93.8%, and 93.3% in 2012, 2013, 2014 and 2015 at Exelon-operated nuclear plants excluding Salem and CENG. These estimates of expected generation in 2012,
2013, 2014 and 2015 do not represent guidance or a forecast of future results as Exelon has not completed its planning or optimization processes for those years.  (5) Percent of expected
generation hedged is the amount of equivalent sales divided by expected generation.  Includes all hedging products, such as wholesale and retail sales of power, options and swaps. Uses
expected value on options. (6) Effective realized energy price is representative of an all-in hedged price, on a per MWh basis, at which expected generation has been hedged.  It is developed by
considering the energy revenues and costs associated with our hedges and by considering the fossil fuel that has been purchased to lock in margin. It excludes uranium costs and RPM
capacity revenue, but includes the mark-to-market value of capacity contracted at prices other than RPM clearing prices including our load obligations.  It can be compared with the reference
prices used to calculate open gross margin in order to determine the mark-to-market value of Exelon Generation's energy hedges. (7) Spark spreads shown for ERCOT and New England.

(1) Based on September 30, 2012 market conditions and hedged position. Gas price sensitivities are based on an assumed gas-power relationship derived from an internal model
that is updated periodically. Power prices sensitivities are derived by adjusting the power price assumption while keeping all other prices inputs constant. Due to correlation of the
various assumptions, the hedged gross margin impact calculated by aggregating individual sensitivities may not be equal to the hedged gross margin impact calculated when
correlations between the various assumptions are also considered. (2) Excludes Maryland assets to be divested. (3) Includes CENG Joint Venture (4) Sensitivities based on
commodity exposure which includes open generation and all committed transactions.

Exelon Generation Hedged Gross Margin Upside/Risk
2012 3Q Earnings Release Slides
2012 3Q Earnings Release Slides
(1) Represents an approximate range of expected gross margin, taking into account hedges in place, between the 5th and 95th percent confidence levels assuming all unhedged
supply is sold into the spot market.  Approximate gross margin ranges are based upon an internal simulation model and are subject to change based upon market inputs, future
transactions and potential modeling changes. These ranges of approximate gross margin in 2013 and 2014 do not represent earnings guidance or a forecast of future results as
Exelon has not completed its planning or optimization processes for those years. The price distributions that generate this range are calibrated to market quotes for power, fuel, load
following products, and options as of September 30, 2012 (2) Gross Margin Upside/Risk based on commodity exposure which includes open generation and all committed

Net of costs recoverable through EIMA. During the fourth quarter of 2011, ComEd received a credit of $0.04 earnings per share, net of amortization, for the allowed recovery of certain 2011
storm costs pursuant to EIMA. During the fourth quarter of 2012, ComEd anticipates recording $0.10 earnings per share to recognize the impact of the ICC’s rehearing decision issued on
October 3, 2012.
Due to the true-up mechanism in the distribution formula rate, the primary driver of year-over-year change in earnings will be due to changes in allowed ROE, rate base and capital structure.

GAAP to Operating Adjustments
32
Exelon’s 2012 adjusted (non-GAAP) operating earnings outlook excludes the earnings effects of the
following:
-
Mark-to-market adjustments from economic hedging activities
-
Unrealized gains and losses from nuclear decommissioning trust fund investments to the extent not
offset by contractual accounting as described in the notes to the consolidated financial statements
-
Financial impacts associated with the planned retirement of fossil generating units and the expected
sale in the fourth quarter of 2012 of three generating stations as required by the merger
-
Changes in decommissioning obligation estimates
-
