|Overview

Overall, Q1 2006 was a strong quarter, with an 11% increase in
operating earnings over Q1 2005

Year-over-year improvement at Detroit Edison due to expiration of the
residential rate cap and lower choice volumes

Flat earnings at MichCon with the rate increase offset by significantly
warmer weather

Non-utility earnings increased due to flow back of timing-related
impacts partially offset by higher synfuel deferrals

We are maintaining our 2006 guidance* which forecasts a 10-20%
increase in operating earnings over 2005

As we detailed at our Business Update meeting earlier this month, we
are planning substantial investments in our utility and non-utility
businesses, which will provide the potential for average operating
earnings growth of 9-10% from 2006-2010


* 2006 guidance assumes no synfuel tax credit phase out; see slide 15 for phase out impacts

|Q1 2006 Synfuel Earnings

($ millions, after-tax)

Power & Industrial Projects:

Synfuel

Q1 2005 vs. Q1 2006 Variance


Production income was
consistent year-over-year

In both periods, we deferred
recognition of a substantial
portion of our synfuel
revenue

Due to changes in the
agreements with our synfuel
partners, a significantly
higher percentage of the
expected payments in 2006
may be variable note
payments

|Unconventional Gas Production:

2006 Barnett Development Plan

During 2006 we plan to rapidly increase
production from our northern acreage

Forecast net production of 4.1 Bcf, ~500%
increase over 2005

Expect to see a 300%-400% increase in our
production rate from Tarrant, Johnson and
Jack counties

Currently have 10 million cubic feet of
production awaiting pipeline completions



We will also focus on testing our southern
acreage:

Drill 4 additional test wells in four distinct
areas

Large operators are also evaluating the
southern area

This will produce a clearer picture of our
potential reserves by year end

We expect to begin some production from
the southern acreage in 2006



Net Production Rate

(mmcf/day)

Barnett production is expected to increase significantly throughout the year

|2006 Guidance

DTE Energy

2006 Operating Earnings Guidance*

($ millions)


** Includes estimated synfuel earnings of $210-220M, assuming no synfuel tax credit phase out

*** Includes estimated Energy Trading earnings of $45M

* Reconciliation to GAAP reported earnings included in the appendix

Our guidance currently remains
unchanged and assumes no phase out of
synfuel tax credits

If oil prices remain high, some amount of
synfuel tax credit phase out is likely

The potential impacts of a phase out are
detailed on the next slide

Legislation that would use the prior year
oil prices to determine current year
reference price is currently in conference
committee

If the 2006 tax credit reference price were
based on 2005 oil prices, there would be
no phase out of 2006 synfuel tax credits

We will update our guidance as events
merit

While current guidance assumes no phase-out,
some level of tax credit phase out is likely

Assumptions for potential phase out impact:

Cash & net income benefits from oil
hedges currently in place

No additional oil hedges are established

Recovery of operating expenses from our
partners

No impairments of synfuel assets

At the top end of the phase out range, we have
in place additional hedges, resulting in more
protection at the 100% phase out level

The percentage of cash flow protected differs
from the percentage of net income protected
due to: AMT carryforward utilization, fourth
quarter accruals and the differences between
cash and GAAP tax rates

Budget/tax reconciliation legislation is currently
in conference committee

|DTE Energy's Investment Thesis

Strong Q1 2006 results - 11% operating
earnings improvement over Q1 2005

DTE Energy plans to create significant value for
shareholders over the next five years

The utilities are positioned to grow earnings 6%
per year while driving a customer focused
investment program

Our three non-utility businesses have
opportunities to grow earnings and increase
cash flow

The balance sheet is stable and we have
sufficient flexibility to execute our plan

The dividend yield is attractive, and as the
payout ratio decreases, we are open to
considering a dividend increase

##### 



|Synfuel Earnings Background

Quarterly earnings from synfuels primarily come from two
sources:



Quarterly payments received from partners in our projects
as tax credits are allocated to them

These payments are subject to gain recognition accounting



Mark to market gains/losses from the oil options we
purchased last year to protect a portion of our synfuel
cash flow that is exposed to crude oil price risk

The hedge does not qualify for hedge accounting; the
changes in fair market value are recorded in current earnings

|----------------------------------------------------------------------------------------------------------------------------------------



---



##### 



|Reconciliation of Q1 2005 & Q1 2006
Synfuel Reported Earnings to Operating
Earnings

($ millions, after-tax)

Use of Operating Earnings Information - DTE Energy management believes that operating earnings provide a more meaningful representation of the company's
earnings from ongoing operations and uses operating earnings as the primary performance measurement for external communications with analysts and investors.
Internally, DTE Energy uses operating earnings to measure performance against budget and to report to the Board of Directors.
|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### 



|Recognition of Synfuel Earnings:
Payments Received from Buyers

Accounting principles for gain recognition of our synfuel sales
proceeds are conservative

Sale proceeds cannot be recognized until there is evidence they
have become determinable and collectability has been reasonably
assured

It is likely that the reference price for oil will reach the
threshold at which synfuel-related tax credits begin to phase
out

The certainty requirement for recognition of sale proceeds is
very high. More than a remote probability of phase out leads to
not recognizing some portion of sales proceeds for the quarter
|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---



##### 



|Synfuel Cash Protected Assumptions


No prior year tax credit phase out for 2005

No reduction in forecasted taxable income - AMT carryforwards
used by 2010

Excludes impact of potential future incremental hedging

Production forecast is realized

|Unconventional Gas Production:

Increased Barnett Production Has
Provided Additional Scale

In 2004 & 2005 we spent
~$120M in Barnett acquiring
acreage and drilling wells

Completed acquisition of
18,000 acres and 44 producing
wells in 2005

Investment resulted in
significant increase in year
over year production and
reserves

Production is expected to
increase substantially in 2006

Current production of 6 mmcfd

Approximately 10 mmcfd
awaiting pipeline connections

Southern acreage could
provide significant upside to

|Definition of Reserve Classifications

Proved Reserves - quantities of natural gas, natural gas liquids and crude oil
which geological and engineering data demonstrate with reasonable certainty to
be recoverable under existing economic and operating conditions



Unproved Reserves - recovery of unproved reserves is considered to be less
certain than proved reserves.  Estimates of unproved reserves are based on data
similar to proved reserves, but technical, contractual, economic considerations
or Securities and Exchange Commission or other regulations prevent such
reserves from being classified as proved.  Unproved reserves may be further
sub-classified as probable and possible to denote progressively increasing
uncertainty of recoverability.



Probable Reserves - estimates of unproved reserves that data suggest are more
likely than not to be recoverable.

|Reconciliations

In this presentation, DTE Energy provides 2006 guidance for operating earnings, non-utility operating
earnings and non-utility operating earnings in areas of expected future capital investment.  It is likely that
certain items that impact the company's 2006 reported results will be excluded from operating results.  A
reconciliation to the comparable 2006 reported earnings/net income guidance is not provided because it is
not possible to provide a reliable forecast of specific line items such as 2007 oil hedging costs,
Performance Excellence Process restructuring charges and DTE2 implementation charges.  These items
may fluctuate significantly from period to period and may have a significant impact on reported earnings.

2006 Reported Earnings to Operating Earnings

Throughout this presentation there are references to operating earnings, operating earnings in areas of
expected future investment and illustrative profile of operating earnings for the years 2007 to 2010.  These
are not meant to constitute guidance, but rather are indicative of the long-term trends management
currently expects from the business.  It is likely that certain items that impact the company's reported
results for those periods will be excluded from operating results.  A reconciliation to the comparable
reported earnings/net income amounts is not provided because it is not possible to provide a reliable
forecast of specific line items such as oil hedging costs, Performance Excellence Process restructuring
charges, impairments, and DTE2 implementation charges.  These items may fluctuate significantly from
period to period and may have a significant impact on reported earnings.
