Impacts of our view on our hedging activity

•

Over the last several quarters, power prices have increased and heat rates have expanded

•

We have adjusted our strategy by reducing our long heat rate position and increasing our fixed-price length

where we see remaining upside

•

During 4Q, we lowered our cross-commodity hedges monetizing our long heat rate view as heat rates

(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 93.5%, 94.1% and 93.4% in 2015 , 2016 and 2017 respectively at Exelon-operated nuclear plants, at ownership. These estimates of expected generation in

2015, 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. (6) Inclusive of all asset divestitures

as of December 31,2014 and Quail Run, as well as Integrys acquisition

ComEd April 2014 Distribution Formula Rate

Note: Disallowance of any items in the 2014 distribution formula rate filing could impact 2014 earnings in the form of a regulatory asset adjustment. Total disallowances in the 2014

distribution formula rate filing include items that are recoverable via other ratemaking mechanisms.

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 2014 distribution formula rate filing established the net revenue requirement used to set the rates that took effect in January 2015 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 (2013) and current year (2014) projected plant additions.
