2015 1Q Earnings Release Slides
(1) Expected generation is the volume of energy that best represents our commodity position in energy markets from owned or contracted for capacity 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 14 refueling outages in 2015, 12 in 2016, and 15 in 2017 at Exelon-operated nuclear plants, and Salem.  Expected generation assumes capacity factors of  93.0%, 94.1% and
93.4% in 2015, 2016 and 2017 respectively at Exelon-operated nuclear plants, at ownership. These estimates of expected generation in 2016 and 2017 do not represent guidance or a
forecast of future results as Exelon has not completed its planning or optimization processes for those years. (2) Excludes EDF’s equity ownership share of CENG Joint Venture. (3) 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.  (4) 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. (5) Spark spreads shown for ERCOT and New England.

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; Sensitivities based on commodity exposure which includes open generation and all committed transactions; Excludes EDF’s equity share of CENG Joint

inputs, future transactions and potential modeling changes; These ranges of approximate gross margin in 2016 and 2017 do not represent earnings guidance or a forecast

2015 1Q Earnings Release Slides
Proposed Low Carbon Portfolio Standard Legislation (HB
3293 / SB1585)
2015 1Q Earnings Release Slides
What is the purpose of the
legislation?
Beginning
January
1,
2016,
the
Illinois
Power
Agency
(IPA)
must
include
in
electric
utilities’
procurement plans
the procurement of cost-effective low carbon energy credits from low carbon energy resources for all retail
customers.  This procurement process follows the existing renewable energy resources procurement process.
What is a low carbon energy
credit?
A tradable credit that represents the environmental attributes of 1 MW of energy produced from a low carbon
energy resource.  Low carbon energy credits are created every day that low carbon energy resources are
generating power.
What is a low carbon energy, or
“LCE”, resource?
Energy from a generating unit that does not emit any air pollution, such as sulfur dioxide, nitrogen oxide, or
carbon dioxide, including technology fueled by new and existing solar photovoltaic, solar thermal, wind, hydro,
nuclear, tidal energy, wave energy or clean coal.
What quantity of LCE resources is
being procured?
A maximum of 70% of retail sales per year.  Like the renewable energy resources procurement, the LCE
procurement is limited by a separate 2.015% rate increase cap and cannot exceed the IPA’s benchmarks for
renewable energy resources.
Who is purchasing the LCE
credits?
Similar to the renewable portfolio standard, electric utilities would purchase the LCE credits.  While the
renewables procurement includes only eligible retail customers, the LCE procurement covers all retail
customers.
How will the utility recover its
costs to purchase LCE credits?
Utilities will recover all costs associated with purchasing LCE credits through a rider that adds a charge to each
retail customer’s bill (consistent with the 2.015% rate cap).  Like the renewable portfolio standard, this charge
will remain fixed for the duration of the LCPS.
What is the procurement
process?
The LCE procurement process relies on the same process the IPA uses to procure renewable energy resources. 
The key difference is the need to conduct a mid-year procurement.  Because the legislation
probably will not become law until after the start of the 2015/2016 procurement year on June 1, 2015,
the
IPA
will
conduct
and
complete
an
initial
procurement
before
January
1,
2016
that
will
procure
the
LCE
credits
needed
for
the
period
January
1,
2016
through
May
31,
2021,
by
entering
into
contracts
of
1
to
5
years
in length.
The
IPA
may
also
conduct
later
procurement
processes
if
it
needs
to
do
so.
How long will the new LCE
procurement requirements be in
effect?
The
new
LCE
procurement
requirements
will
sunset
on
December
31,
2021,
so
long
as
the
State
has
adopted
and
implemented
a
plan
under
Section
111(d)
of
the
federal
Clean
Air
Act.
If
the
State
has
not
completed these actions by that date, then the new requirements will sunset on December 31 of the year in
which the State adopts and implements that plan.

ComEd April 2015 Distribution Formula Rate
Note:  Disallowance of any items in the 2015 distribution formula rate filing could impact 2015 earnings in the form of a regulatory asset adjustment.
Given the retroactive ratemaking provision in the Energy Infrastructure Modernization Act (EIMA) legislation, ComEd net income during the year will
be based on actual costs with a regulatory asset/liability recorded to reflect any under/over recovery reflected in rates.  Revenue Requirement in
rate filings impacts cash flow.

The 2015 distribution formula rate filing establishes the net revenue requirement used to set the rates that will take effect
in January 2016 after
the Illinois Commerce Commission's (ICC’s) review. There are two components to the annual distribution formula rate filing:
Filing Year:  Based on prior year costs (2014) and current year (2015) projected plant additions. 
Annual Reconciliation: For the prior calendar year (2014), this amount reconciles the revenue requirement reflected in rates during the prior year
(2014) in effect to the actual costs for that year. The annual reconciliation impacts cash flow in the following year (2016) but  the earnings impact
has been recorded in the prior year (2014) as a regulatory asset.

PECO Electric LTIIP -
System 2020
PECO filed its Electric Long Term Infrastructure Improvement Plan (“LTIIP”) along
with its associated recovery mechanism the Distribution System Improvement
Charge (“DSIC”)  on March 27, 2015 (with Electric Distribution Rate Case)
o
LTIIP
includes
$275
million
in
incremental
capital
spending
from
2016-2020
focusing on the following areas:
Cable Replacement
Storm Hardening Programs
Substation replacement and upgrades
o
DSIC mechanism will allow recovery of eligible LTIIP spend between rate
cases if the electric distribution ROE falls below the DSIC ROE established by
PaPUC.  The current Electric DSIC ROE is 10.1%.
o
Expected approval in 3Q15
PECO also proposed the concept of constructing one or more pilot
microgrid
projects as part of a future LTIIP update ($50-$100M).  The objective is to
evaluate and test emerging microgrid technologies that could enhance reliability
and resiliency by replacing obsolete infrastructure as an alternative to traditional
solutions.

CENG.
Reflects revenues from operating services agreement with Fort Calhoun, variable interest entities, funds collected through revenues for decommissioning the former PECO 
nuclear plants through regulated rates and gross receipts tax revenues.
Reflects the cost of sales and depreciation expense of certain Constellation businesses of Generation.
All amounts rounded to the nearest $50M.
Excludes the impact of the operating exclusion for mark-to-market due to the volatility and unpredictability of the future changes to power prices.
