 Early Retirement of Clinton and Quad Cities We will shut down Clinton Power Station on June 1, 2017 and Quad Cities Generating Station on June 1, 2018 if Illinois does not pass adequate legislation by May 31, 2016 and if Quad Cities does not clear the 19/20 PJM capacity auction in May Impact on Illinois of Plant Closures (1) • The gross impact of shutting down Clinton and Quad Cities would be: • $1.2 billion annually in lost economic activity in Illinois • 4,200 jobs lost, many of which are highly skilled, good paying jobs • According to independent analyses by PJM and MISO, there would be a significant increase in electricity prices for Illinois residents and businesses • Economic damages associated with an incremental increase in the release of carbon dioxide emissions would cost Illinois consumers nearly $10 billion over 10 years Nuclear Plant Economics Deteriorating • Illinois legislation aimed at leveling the playing field for zero carbon resources has failed to advance in the past two legislative sessions • PJM power prices hit 15 year record low in March • Illinois forward energy prices have declined by roughly 10% in the last year • From 2009 to 2015, Quad Cities and Clinton have sustained more than $800 million in cash flow losses on a pre-tax basis (2) (1) Source: January 5, 2015 Response to the IL General Assembly Concerning House Resolution 1146 prepared by Illinois Commerce Commission, Illinois Power Agency, Illinois Environmental Protection Agency, and Illinois Department of Commerce and Economic Opportunity (2) Revenues include realized energy and capacity revenue excluding any hedges; costs include all site expenses (including taxes other than income taxes), DOE spent fuel fees prior to their suspension in mid-2014, charged and allocated overhead, fuel capex, and non-fuel capex.

Expected generation assumes 12 refueling outages in 2016, 15 in 2017, and 14 in 2018 at Exelon-operated nuclear plants, and Salem. Expected generation assumes capacity factors of 94.1%, 93.4% and 93.7% in 2016, 2017 and 2018 respectively at Exelon-operated nuclear plants, at ownership. These estimates of expected generation in 2017 and 2018 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.

 35 Q1 2016 Earnings Release Slides ComEd April 2016 Distribution Formula Rate Docket # 16-0259 Filing Year 2015 Calendar Year Actual Costs and 2016 Projected Net Plant Additions are used to set the rates for calendar year 2017. Rates currently in effect (docket 15-0287) for calendar year 2016 were based on 2014 actual costs and 2015 projected net plant additions Reconciliation Year Reconciles Revenue Requirement reflected in rates during 2015 to 2015 Actual Costs Incurred. Revenue requirement for 2015 is based on docket 14-0312 (2013 actual costs and 2014 projected net plant additions) approved in December 2014. Common Equity Ratio ~ 46% for both the filing and reconciliation year ROE 8.64% for the filing year (2015 30-yr Treasury Yield of 2.84% + 580 basis point risk premium) and 8.59% for the reconciliation year (2015 30-yr Treasury Yield of 2.79% + 580 basis point risk premium – 5 basis points performance metrics penalty). For 2016 and 2017, the actual allowed ROE reflected in net income will ultimately be based on the average of the 30-year Treasury Yield during the respective years plus 580 basis point spread, absent any metric penalties Requested Rate of Return ~ 7% for both the filing and reconciliation years Rate Base $8,830 million– Filing year (represents projected year-end rate base using 2015 actual plus 2016 projected capital additions). 2016 and 2017 earnings will reflect 2016 and 2017 year-end rate base respectively. $7,780 million - Reconciliation year (represents year-end rate base for 2015) Revenue Requirement Increase $138M increase ($1M decrease due to the 2015 reconciliation and collar adjustment offset by a $139M increase related to the filing year). The 2015 reconciliation impact on net income was recorded in 2015 as a regulatory asset. Timeline • 04/13/16 Filing Date • 240 Day Proceeding The 2016 distribution formula rate filing established the net revenue requirement used to set the rates that will take effect in January 2017 after the Illinois Commerce Commission's (ICC’s) review. There are two components to the annual distribution formula rate filing: • Filing Year: Based on 2015 costs and 2016 projected plant additions. • Annual Reconciliation: For 2015, this amount reconciles the revenue requirement reflected in rates in effect during 2015 to the actual costs for that year. The annual reconciliation impacts cash flow in 2017 but the earnings impact has been recorded in 2015 as a regulatory asset. 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. |
