 4 Alternative Regulation (Alt Reg) Proposal • ComEd plans to make a companion Alt Reg filing proposing to recover the costs of smart grid and other projects outside of the traditional rate case process – 9-month statutory process • The proposal includes a “flow-through mechanism” to recover capital carrying costs and incremental O&M, as incurred • Costs and investments will be rolled in to future rate cases, when they occur • Assured savings to customers – $2 million on capped O&M costs for program costs (excluding CARE) • Includes an incentive/penalty mechanism for performance above or under budget Alt Reg Proposal is permitted under ICC section 9-244 $30 $15 Man-hole refurbishment and cable replacement - $10 Expanded funding for low income CARE programs $5 - Electric Vehicle Fleet Purchase $55 $40 - $10 - $20 Accelerated Smart Grid Deployment • 190,000 additional AMI Meters and Outage Management System Interface • Accelerated deployment of Distribution Automation • Customer Applications Capital O&M $ millions |
 5 Residential Rate Design – Straight Fixed/Variable Proposal • Filing includes a proposal to gradually move more of residential delivery bill to the fixed customer charge, rather than usage-based kwh component through three step phase-in Current rate design: 37% fixed / 63% variable split Proposed: 60%/40% split in June 2011; 70%/30% in June 2012, and 80%/20% in June 2013 • Mitigates impact of weather and load fluctuations due to weather and economy • Rate design reflects current cost structure and sends appropriate price signals – Fixed costs to be collected via fixed charges (i.e. Customer Charge, Meter Charge) – Variable costs to be collected via variable charges (i.e. per kWh) • Eliminates economic disincentive to promote energy efficiency Proposed Straight Fixed/Variable rate design is consistent with ICC orders in other recent cases |

Unit rates: cents / kWh All Other (2) Transmission Energy Distribution Approximately 4% increase July 1, 2010 July 1, 2011 Transmission: Subject to FERC formula rate annual update.

Distribution: As proposed. 12.63 13.09 Note: Amounts may not add due to rounding. Proposed residential rate impact of 7% will be mitigated by impact of lower capacity prices resulting in an increase of 4% |
