Factors Influencing PJM RPM Capacity Auction
(Comparison of PY 14/15 and PY 13/14 Price Drivers)
Exelon
Price Impact
Cost of Environmental Upgrades
(1)
Higher Net CONE
(2)
Higher Net ACRs
For Coal Units
(3)
Import Transmission Limits And Objectives 
(muted impact on portfolio revenues due to regional diversification)
NJ CCGT Proposal / PJM Minimum Offer Price Rules
Peak Load
(4)
Demand Response Growth
2014/15 PJM Capacity Auction: Expected
Changes Since Planning Year 2013/14
Exelon’s capacity position, split almost evenly between the west and the east,
dampens the volatility to portfolio revenues from changes to transmission limits
while retaining upside across the fleet from upcoming EPA regulations
(1)  We expect generators to reflect cost of capital expenditures into their cost based offers at the upcoming auction.
(2)
Cost
of
new
entry
(CONE)
increased
by
7.6%
(for
RTO)
and
5.3%
to
6.5%
(within
Locational
Deliverability
Areas
(LDAs)).
(3)  Replacing
2007
net
revenues
with
significantly
lower
2010
revenues
in
the
Net
ACR
(avoidable
cost
rate)
calculations
for
coal
generators
may
increase
offer
caps
for
certain coal generators in the next auction. However, some coal units may not be affecteddue to high net revenues compared to avoidable costs.
(4)  Peak load reduced by approx. 1% in RTO (excluding the impact from Duke Ohio integration).

Assumptions
2011
2012
2010
The decrease in pension expense in 2011 is primarily due to the $2.1 billion pension
contribution,
partially
offset
by
the
effects
of
lower
discount
rates
and
a
decrease
in
EROA
(1)  
Pension expense amounts exclude settlement charges.
(2) 
Management considers various factors when making pension funding decisions, including actuarially determined minimum contribution requirements under ERISA, contributions
required to avoid benefit restrictions and at-risk status as defined by the Pension Protection Act of 2006 (the Act), management of the pension obligation and regulatory
implications. The Act requires the attainment of certain funding levels to avoid benefit restrictions (such as an inability to pay lump sums or to accrue benefits prospectively), and
at-risk status (which triggers higher minimum contribution requirements and participant notification).
Note: Slide provided for illustrative purposes and not intended to represent a forecast of future outcomes. Assumes an ~25% capitalization of pension and OPEB costs. 
  EROA = earned return on assets
The decrease in pension expense in 2011 is primarily due to the $2.1 billion pension 
contribution, partially offset by the effects of lower discount rates and a decrease in EROA

(as of December 31, 2010)

Important Information
The following slides are intended to provide additional information regarding the hedging
program at Exelon Generation and to serve as an aid for the purposes of modeling Exelon
Generation’s gross margin (operating revenues less purchased power and fuel expense). The
information on the following slides is not intended to represent earnings guidance or a forecast
of future events.  In fact, many of the factors that ultimately will determine Exelon Generation’s
actual gross margin are based upon highly variable market factors outside of our control.  The
information on the following slides is as of December 31, 2010.  We update this information on a
quarterly basis.
Certain information on the following slides is based upon an internal simulation model that
incorporates assumptions regarding future market conditions, including power and commodity
prices, heat rates, and demand conditions, in addition to operating performance and dispatch
characteristics of our generating fleet.  Our simulation model and the assumptions therein are
subject to change.  For example, actual market conditions and the dispatch profile of our
generation fleet in future periods will likely differ – and may differ significantly – from the
assumptions underlying the simulation results included in the slides.  In addition, the forward-
looking information included in the following slides will likely change over time due to continued
refinement of our simulation model and changes in our views on future market conditions.

Portfolio Management Objective
Align Hedging Activities with Financial Commitments
Power Team utilizes several product types
and channels to market
Wholesale and retail sales
Block products
Load-following products
and load auctions
Put/call options
Exelon’s hedging program is designed to
protect the long-term value of our
generating fleet and maintain an
investment-grade balance sheet
Hedge enough commodity risk to meet future cash
requirements if prices drop
Consider:  financing policy (credit rating objectives,
capital structure, liquidity); spending (capital and
O&M); shareholder value return policy
Consider market, credit, operational risk
Approach to managing volatility
Increase hedging as delivery approaches
Have enough supply to meet peak load
Purchase fossil fuels as power is sold
Choose hedging products based on generation
portfolio –
sell what we own

Reference Prices
(1)
Based on December 31, 2010 market conditions. 
(2)
Gross margin is defined as operating revenues less fuel expense and purchased power expense, excluding the impact of decommissioning and other incidental revenues. Open
gross margin is estimated based upon an internal model that is developed by dispatching our expected generation to current market power and fossil fuel prices.  Open gross margin
assumes

than

margin
contains assumptions for other gross margin line items such as various ISO bill and ancillary revenues and costs and PPA capacity revenues and payments.  The estimation of open
gross margin incorporates management discretion and modeling assumptions that are subject to change.

Generation Profile
(1)
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 12 refueling outages in
2011 and 10 refueling outages in 2012 and 2013 at Exelon-operated nuclear plants and Salem.  Expected generation assumes capacity factors of 93.0%, 93.6% and 93.1% in 2011, 2012 and 2013 at Exelon-
operated nuclear plants. These estimates of expected generation in 2012 and 2013 do not represent guidance or a forecast of future results as Exelon has not completed its planning or optimization processes
for those years.
(2)
Percent of expected generation hedged is the amount of equivalent sales divided by the expected generation.  Includes all hedging products, such as wholesale and retail sales of power, options, and swaps. 
Uses expected value on options. Reflects decision to permanently retire Cromby Station and Eddystone Units 1&2 as of May 31, 2011.  
(3)
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.

Exelon Generation Gross Margin Sensitivities
(with Existing Hedges)
(1) 
Based on December 31, 2010 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.

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 2012 and 2013 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 December 31, 2010.
