PRESENTATION SUMMARY

S1. Business Review (D.M.) 1. Highlights: 1. 2006 was a good year for DTE. 2. Operating earnings were higher YoverY driven by stronger performance at Detroit Edison. 3.

Invested $1.1b in the two utilities.

5. At EEI last fall, DTE developed a restructuring plan for

non-utility businesses. 6. In 2006, DTE increased the dividend 3% to $2.12 and repurchased 1m shares of stock. 2. Operating Results: 1. Last fall, DTE laid out its growth plans. 2. At both utilities, DTE target an 11% ROE and will target growth in those businesses 5-6%, driven by mandated expenditures like environmental improvements at Detroit Edison. 3. Will continue to increase reliability and customer satisfaction, while reducing cost structure. 4. Goal is to move the higher CapEx that will be making in to rates in a timely fashion. 3. Non-Utility:

1. Restructuring will provide over $800m in proceeds, and when

combined with the higher synfuel cash will provide over a $1b

in proceeds. 2. Expects to make continued investments in all three businesses not only before but after the restructurings.

4. Michigan Plan: 1. The state of Michigan recently released its collaborative 21st Century Energy Plan. 2. Plan point towards annual demand growth in Michigan of 1.2%, which results in a need for an estimated 800-megawatt of base load capacity and 2,200 megawatts of peaking capacity by 2015. 1. Expected to be the state's utilities. 3. Plan also has two other important recommendations. 1. Advocates legislative changes as an option to fix the state's electric regulatory structure and customer choice.

2. Recommends a statewide RPS of 3% by 2009 and 7-10% by 2015.

5. Rate Case: 1. Detroit Edison will file its rate case during 2Q07 and DTE expects new rates would be effective about mid-2008.

2. Some of the areas that this case will focus on includes:

1. Full and timely recovery of CapEx, especially environmental capital. 2. Continued progress on rate deskewing. 3. Continued progress in addressing Michigan's unique regulatory structure.

3. For MichCon, Co. plans to file a case this year and that would

focus on revenue decoupling and capital recovery. 6. Performance Excellence Plan (PEP process): 1. PEP process is focused on customer satisfaction and driving down cost. 1. This will allow DTE to consistently achieve ROE targets and minimize the impact of higher CapEx on customers. 2. Made good process improvements in 2006. 3. Program looks at all elements of performance in order to drive high customer satisfaction and low cost. 4. Has about 2,000 projects underway right now. 1. One of these that Co. is working on. 2. Project underway will enable Co. to clear more miles per year. 1. Has been clearing about 4,800 miles a year. 2. Going to clear 6,800 miles a year, which will put DTE on a 4.5-year cycle. 3. Will do more miles at lower cost. 4. Team spent sometime re-engineering the process. 5. By 2011, expects a 40% reduction in cost per mile. 6. Substantial reduction in cost per mile, more miles cleared, saves money, drives higher customer satisfaction,

and lower storm cost over time. 5. Overall for the PEP process, total O&M and capital savings for 2006 was $45m. 1. Does not include another $50m in PSCR savings that will flow through customers.

6. Run rate at the end of 2006 for O&M and capital was $160m.
