Exhibit 99.1

July 27, 2006

DTE Energy reports second quarter 2006 earnings;
Maintains 2006 earnings guidance

     DETROIT — DTE Energy (NYSE:DTE) today reported a second quarter 2006 loss of $33 million, or $0.19 per diluted share, compared with reported earnings of $29 million, or $0.17 per diluted share in the second quarter of 2005.

     The company had an operating loss for the second quarter 2006 of $1 million, or $0.01 per diluted share, compared with second quarter 2005 operating earnings of $40 million, or $0.23 per diluted share. Operating results exclude non-recurring items, certain timing-related items and discontinued operations.

     “Although this quarter’s earnings did not meet our expectations, our plan for long-term growth remains on track,” said Anthony F. Earley Jr., DTE Energy chairman and CEO. “The impact of high oil prices on our synfuel operations has created negative pressure on earnings, and Congress, despite several efforts, has not taken steps to create more certainty about the future of synfuel tax credits. We are pleased, however, that our proactive hedging of synfuel production has enabled us to protect about $1 billion of cash from synfuels from 2006 to 2009. We intend to use this cash to create value for shareholders through investments in our businesses.

     “From an operational standpoint, improvements generated from our Performance Excellence Process are starting to produce results,” Earley continued. “We have approved voluntary separations for approximately 350 employees and we remain on track to generate between $50 million and $100 million of savings for 2006 for customers and shareholders.”

     Reported earnings for the six months ended June 30, 2006, were $103 million, or $0.58 per diluted share versus $151 million or $0.87 per diluted share in 2005. Year-to-date operating earnings were $170 million, or $0.95 per diluted share, compared with $194 million, or $1.11 per diluted share in 2005. Reconciliations of reported to operating earnings for both the quarter ended and six months ended June 30, 2006 and 2005, are at the end of this news release.

Utility growth plan on track

     Construction of the new selective catalytic reduction system at Detroit Edison’s Monroe Power Plant is on schedule for mid-2007 completion. The flue gas desulfurization system project for the Monroe plant is also on schedule, with individual units planned for completion in 2008 and 2010. Together, these systems should significantly reduce emissions of nitrogen oxide, sulfur dioxide and mercury, enabling Detroit Edison to continue to supply customers with electricity from low-cost coal while minimizing environmental impact. In the first half of 2006, Detroit Edison invested $80 million in environmental projects and $420 million on other generation and distribution system improvements.

     MichCon also began work on several capital projects to benefit customers, including a gas distribution system expansion to meet growing demand in western Michigan and a gas storage expansion. In compliance with the federal Pipeline Safety Act, MichCon continues to inspect and repair its distribution system in areas of high population, with more than 170 miles of pipeline completed in 2006. In the first half of 2006, MichCon invested $52 million in these projects and other system improvements.

Non-utility value creation continues

     Power & Industrial Projects: DTE Energy continued to build its on-site, private utility services business by expanding operations with an existing customer. The company also negotiated deals for purchased power at one of its peaking plants and sales of excess gas from one of its coke batteries. In the first half of 2006, DTE Energy invested $49 million in the Power & Industrial Projects segment.

     Unconventional Gas Production: In the first half of 2006, DTE Energy drilled 75 wells and produced 10.5 billion cubic feet of natural gas equivalent (Bcfe) in its Antrim shale properties in Michigan, and is on track to drill approximately 130 wells and produce 22.4 Bcfe for the full year 2006. In its Barnett shale properties in Texas, the company successfully drilled 25 wells and produced 1.5 Bcfe in the first half of 2006, and is on track to drill 55 wells and produce 4.1 Bcfe for the full year 2006. DTE Energy invested $89 million in the Unconventional Gas Production segment in the first half of 2006.

     Fuel Transportation & Marketing: To expand its coal marketing capabilities, DTE Energy began development of a coal terminal in Chicago expected to handle 5 million tons of coal per year. In April, the company completed a project to add 14 Bcf of non-utility gas storage capacity in Michigan. In the first half of 2006, DTE Energy invested $44 million in the Fuel Transportation & Marketing segment.

Operating earnings results for the second quarter of 2006, by segment:

     Electric Utility: Operating earnings for Detroit Edison were $0.46 per diluted share versus $0.26 in the second quarter 2005. The key earnings driver was higher gross margin due to the Jan. 1, 2006, expiration of the cap on residential rates and the return of Electric Choice customers to full utility service. Second quarter 2006 reported earnings were $0.33 per diluted share, which included $0.13 per diluted share of costs to achieve Performance Excellence Process savings, compared to reported earnings of $0.24 in the second quarter of 2005.

     Gas Utility: Primarily consisting of MichCon, this segment had a seasonal operating loss of $0.05 per diluted share compared with a loss of $0.01 in the second quarter 2005. The main factor impacting earnings was lower customer gas usage due to conservation and milder weather, with 10 percent fewer heating degree days than in the second quarter of 2005.

     Power and Industrial Projects: Primarily due to reserves against the uncertain value of synfuel tax credits, this segment had an operating loss of $0.26 per diluted share versus a profit of $0.12 in the second quarter of 2005.

     Unconventional Gas Production: Operating earnings for this segment were $0.01 per diluted share, an increase of $0.01 compared with the second quarter of 2005, primarily due to higher production from the Barnett shale and the expiration of some fixed-price Antrim shale gas contracts.

     Fuel Transportation and Marketing: This segment had an operating loss of $0.07 per diluted share compared with breakeven results in the second quarter of 2005. Driving earnings higher were increased gas storage margins and reduced overhead; however, falling natural gas spot prices necessitated a timing-related lower of cost or market adjustment to reduce the value of inventory in storage, which resulted in lower overall segment earnings.

     Corporate & Other: Operating results improved by $0.04 per diluted share compared with the second quarter of 2005, primarily due to lower interest expense. This segment had an operating loss of $0.10 in the second quarter of 2006 compared with an operating loss of $0.14 in the second quarter of 2005.

Outlook for 2006

     As previously announced, DTE Energy expects 2006 operating earnings excluding synfuels of $2.41 to $2.66 per diluted share. Earnings guidance for individual segments may differ from the ranges shown in DTE Energy’s previous guidance issued April 6, 2006.

     “Based on our year-to-date performance, we are maintaining our earnings guidance excluding synfuels,” said David E. Meador, DTE Energy executive vice president and chief financial officer. “We are also maintaining our guidance for 2006 cash flow from operations of $1.1 billion to $1.15 billion. We believe the potential reduction in synfuel cash this year can be offset by stronger cash flow from our other businesses. This internal cash generation will be an important source of funds for our future growth investments.”

Conference call and webcast information

     This earnings announcement, as well as a package of supplemental financial information, is available on the company’s website at www.dteenergy.com/investors.

     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.

     In this release, DTE Energy discusses 2006 operating earnings guidance. 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 guidance is not provided because it is not possible to provide a reliable forecast of specific line items such as 2007 oil hedging costs and other charges. These items may fluctuate significantly from period to period and may have a significant impact on reported earnings.
