28 Detroit Edison Rate Case Filing Detroit Edison's Estimated Revenue Deficiency Key Elements Anticipate self implementing some portion of rate request on or after July 26, 2009 Rate request primarily driven by economic pressures impacting sales, uncollectible expense and pension costs Includes proposal for decoupling revenue from sales volumes Requesting 11.5% ROE vs. current 11% ROE Requesting an uncollectible tracking mechanism similar to MichCon's July 2009 through June 2010 forward-looking test year (CHART) $378 $41 $31 $14 $15 $30 $83 $164 Total Revenue Deficiency Other O&M Rate Base Capital Structure Inflation Uncollectible Exp Benefit Costs Sales Reduction

Legislation Strengthened Michigan's Regulatory Framework Cap Electric Choice at 10% Deskewing of customer rates reduces Choice incentives File and use rate-making Self-implement rates after 6 months 12 month deadline for rate cases Forward test year Renewable Portfolio Standard & Energy Efficiency Separate funding provisions Cost to rate payers is transparent Cost caps and off-ramps Certificate of need process Funds interest during construction 29 Reduces utility risk profile 12 month rate case deadline and 6 month file and implement reduces regulatory lag, not only for rate base increases but also load and expense risk RPS structure provides for pre- funding, avoids regulatory lag, caps obligation to customers and provides off-ramps to utilities if targets aren't achievable

30 Requires up to 10% of retail sales to come from renewable sources by 2015, with interim targets in prior years designed to "close the gap" New capacity requirements of 300 MWs by 2012; 600 MWs by 2015 Qualified technologies include: wind, solar, biomass, hydro, some co-generation applications Must be Michigan based Allows 50% of new renewable sources to be utility built Remainder to be sourced through competitive bids Limits on rate impacts are implemented through "cost caps", which are structured to level cost recovery over 20 years "Off ramp" provisions allow extensions or reductions in targets if costs are excessive or other constraints prevent compliance Key Provisions of the Michigan RPS Legislation Targets Compliance Options Ownership Cost Caps 30

31 Key Provisions for EO Legislation in Michigan Compliance Options Targets Funding Includes energy efficiency, conservation, and demand response (electric) Providers (utilities) can operate compliance programs or fund a state program Legislation limits annual spending via a customer surcharge Funds received from a customer class must be spent on that class All classes will contribute toward low income residential programs Earnings Requires Detroit Edison programs to ramp to 1% annual savings by 2012 Requires MichCon programs to ramp to 0.75% savings by 2012 Up to 2/3 of total spend can be capitalized, generating earnings at allowed ROE Detroit Edison and MichCon each can earn incentives of up to 15% of total annual spend by exceeding reduction targets MichCon may decouple revenues from volumetric sales if EO spend is at least 0.5% of revenue
