EXHIBIT 99.1

DTE Energy reports solid 2017 financial results; positive impact of tax reform provides significant benefit to customers and improves 2018 guidance

• Passing tax reform savings to customers

• Ranked highest in customer satisfaction with gas and electric business customers in the Midwest by J.D. Power

• Committed to reducing carbon emissions 80 percent by 2050

DETROIT, Feb. 16, 2018 - DTE Energy (NYSE:DTE) today reported 2017 earnings of $1.1 billion, or $6.32 per diluted share, compared with $868 million, or $4.83 per diluted share in 2016. Reported 2017 earnings were higher primarily driven by results in the non-utility businesses.

2017 operating earnings were $1.0 billion or $5.59 per diluted share, compared with 2016 operating earnings of $948 million, or $5.28 per diluted share. Operating earnings exclude non-recurring items, certain mark-to-market adjustments and discontinued operations. Reconciliations of reported earnings to operating earnings are included at the end of this news release.

“2017 was a very good year for DTE,” said Gerry Anderson, DTE Energy chairman and CEO. “Our financial performance was strong, but I am even prouder of some of the things we accomplished this past year that were important to our customers, our communities and our employees.”

Anderson noted the following accomplishments:

• Passing tax reform savings to customers: The lower corporate tax rate resulting from the recent passage of the Federal Tax Cuts and Jobs Act will be passed on to our customers, lowering bills for DTE’s utility customers by $190 million annually.

• Provided power restoration assistance in Florida and Puerto Rico: DTE Energy sent 600 employees and contractors to Florida and another 80 to Puerto Rico to help restore power following massive hurricanes. Such mutual assistance is a hallmark of the electric power industry.

• Led the Midwest in business customer satisfaction: DTE Energy ranked highest in customer satisfaction with gas and electric business customers in the Midwest in J.D. Power’s 2017 study. DTE also ranked second in overall customer satisfaction with electric and gas residential customers in the Midwest Large segment. DTE has improved its customer satisfaction score every year since 2012.

• Committed to reduce carbon emissions by 80 percent: Last May, DTE committed to reduce carbon emissions by over 80% by retiring older coal-fired power plants and replacing them with renewables and highly efficient gas plants.

• Placed in the top 4 percent for employee engagement: DTE placed in the top 4 percent of workplaces nationwide for employee engagement, as measured by the Gallup Organization. DTE was also named #7 among Fortune 500 companies on Indeed’s list of 50 Best Places to Work in 2017.

• Supported job creation with Michigan businesses: DTE spent nearly $1.7 billion with Michigan-based companies in 2017, exceeding its commitment to the Pure Michigan Business Connect local supplier initiative. This included more than $500 million spent in the city of Detroit. The company’s seven-year effort to increase spending with Michigan suppliers has supported the creation of nearly 16,000 Michigan jobs.

• Modernized the state’s energy infrastructure: DTE finalized plans for its next $260 million renewable investment in 2018, filed plans for a new, high efficiency gas power plant, invested heavily in the smart grid, and broke ground on the NEXUS pipeline.

“We continue to invest in smarter energy infrastructure aimed at improving reliability and sustainability,” Anderson added. “We are in the midst of a fundamental transformation in the way we produce energy; that transition will be great for the environment, and we are going to keep our product affordable in the process.”

DTE finishes 2017 strong and raises EPS guidance for 2018

DTE Energy raises 2018 operating EPS guidance from $5.48 - $5.88 to $5.57 - $5.99 as a result of the impacts of the passage of the Federal Tax Cuts and Jobs Act.

“DTE delivered strong 2017 financial results at both regulated and non-regulated businesses while continuing significant investment in reliability and infrastructure and we are in a great position to achieve our financial goals in 2018,” said Peter Oleksiak, DTE Energy senior vice president and CFO.

In this release, DTE Energy discusses 2018 operating earnings guidance. It is likely that certain items that impact the company's 2018 reported results will be excluded from operating results. Reconciliations to the comparable 2018 reported earnings guidance are not provided because it is not possible to provide a reliable forecast of specific line items (i.e. future non-recurring items, certain mark-to-market adjustments and discontinued operations).

We undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events.

28 Use of Operating Earnings Information – Operating earnings exclude non-recurring items, certain mark-to- market adjustments and discontinued operations. 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 presentation, DTE Energy provides guidance for future period operating earnings. It is likely that certain items that impact the company’s future period reported results will be excluded from operating results. A reconciliation to the comparable future period reported earnings is not provided because it is not possible to provide a reliable forecast of specific line items (i.e. future non-recurring items, certain mark-to- market adjustments and discontinued operations). These items may fluctuate significantly from period to period and may have a significant impact on reported earnings. Reconciliation of reported to operating earnings (non-GAAP)
