 6 ComEd – Rate Case Summary • ComEd and ICC Staff are in virtual agreement with respect to proper capital structure ~45% equity • Relatively small difference between ComEd’s requested ROE (10.75%) and Staff’s recommendation (10.30%) • ComEd and ICC Staff are much closer on administrative and general (A&G) expenses than in the last rate case • Seeking to reduce regulatory lag by including pro forma capital additions in rate base and pursuing more timely recovery of costs through riders • About 60% of difference between ComEd’s total revenue requirement and Staff’s recommendation relates to “timing” of recovery for 2007 and 2008 capital additions • ALJ Order expected: July 2008 • Final ICC Order expected: September 2008 |
 7 ComEd - Interim Procurement Process ComEd procured ~14% of its energy needs for June 2008 through May 2009 through the procurement of 24 block products for on-peak and off-peak energy The staggered roll-off of the auction contracts and the financial swap have mitigated the rate impact for ComEd residential customers to ~2.5% 0% 33% 67% 100% Auction Contracts Financial Swap Future Procurement by Illinois Power Agency 3/08 RFP Jun 2007 Jun 2008 Jun 2009 Jun 2010 Jun 2011 Jun 2012 Jun 2013 NOTE: For illustrative purposes only.

This will result in a system average rate increase of ~19% PECO’s 2011 full requirements price expected to differ from PPL due, in part, to the timing of the procurement (2011 vs. 2010) and locational differences Rates will vary by customer class and may be impacted by legislation and procurement model Residential Small C&I Round 1, 7/2007 $101.77 $105.11 Round 2, 10/2007 $105.08 $105.75 Round 3, 3/2008 $108.80 $108.76 Average $105.22 $106.54 PPL Procurement Results ($/MWh) |
