Exhibit 99.2

This presentation includes forward-looking statements. There are a number of risks and uncertainties that

could cause actual results to differ materially from the forward-looking statements made herein. The

factors that could cause actual results to differ materially from these forward-looking statements include

Exelon’s ability to achieve the full additional capacity contemplated by the proposed uprates, the

availability of required components and raw materials, and the timing to complete the proposed uprates

and obtain required regulatory approvals as well as those discussed in (1) Exelon’s 2008 Annual Report

on Form 10-K in (a) ITEM 1A. Risk Factors, (b) ITEM 7. Management’s Discussion and Analysis of

Financial Condition and Results of Operation and (c) ITEM 8. Financial Statements and Supplementary

Data: Note 18; (2) Exelon’s First Quarter 2009 Quarterly Report on Form 10-Q in (a) Part II, Other

Information, ITEM 1A. Risk Factors and (b) Part I, Financial Information, ITEM 1. Financial Statements:

Note 13; and (3) other factors discussed in filings with the Securities and Exchange Commission by

Exelon Corporation or Exelon Generation Company LLC (Companies).

Readers are cautioned not to

place undue reliance on these forward-looking statements, which apply only as of the date of this

communication. Neither of the Companies undertakes any obligation to publicly release any revision to its

forward-looking statements to reflect events or circumstances after the date of this communication, except

as required by law.

Forward-Looking Statements

•

A successful 38-megawatt power uprate at Quad Cities in June 2009 launched a series

of planned power uprates across Exelon’s nuclear fleet

•

Uprates equivalent in size of a new nuclear plant but significantly lower cost and shorter

timeline

•

1,300 –

1,500 MW

•

Dollars shown are overnight cost, cost per kW are for MUR and EPU combined

MUR (Measurement Uncertainty Recapture)

Through the use of advanced techniques and more precise

instrumentation, reactor power can be more accurately calculated.

These uprates achieve up to 1.7 percent additional output. MUR

uprates require NRC approval.

EPU (Extended Power Uprate)

Through a combination of more sophisticated analysis and upgrades to

plant equipment, uprates can be obtained for as much as 20 percent of

original licensed power level. EPU uprates require NRC approval.

Evaluation Parameters

•

Exelon has substantial experience managing successful uprate projects

•

1,100 MWs of increased nuclear capacity over the past 10 years

•

Incremental 1,300 –

1,500 MWs of nuclear uprates are safe, economical and

proven methods to improve efficiency and output

Track Record of Execution

Staggered execution provides for continued re-evaluation of project economics

Nuclear uprates span across nine plants

Exelon’s $2,200 –

2,500 / kW overnight cost for its MUR and EPU projects

is better value than the cost for a nuclear new build that has been

estimated as high as $4,500 / kW (2007 dollars)
