DTE Energy Co. is an American Detroit, Michigan-based utility incorporated in 1995 involved in the development and management of energy-related businesses and services nationwide.
DTE Energy's largest operating subsidiaries are DTE Electric Company (formerly Detroit Edison), an investor-owned electric utility serving 2.1 million customers in Southeastern Michigan; and DTE Gas Company (formerly Michigan Consolidated Gas Company (MichCon)), a natural gas utility serving 1.2 million customers in Michigan. The two companies merged in 2001.
The name "DTE" is taken from the stock symbol for the former Detroit Edison, DTE.
As of 2005 DTE Energy has 22 coal-fired generating stations with 7,998 MW of capacity. Here is a list of DTE Energy's coal power plants with capacity over 100 MW:
In 2016, DTE Energy retired three coal-fired generating units among its plants. In June 2016, DTE Energy said that it would close eight additional coal-fired generators at three coal plants in Michigan by the year 2023. The plants are located in River Rouge, St. Clair in East China Township and Trenton. In sum, the plants power around 900,000 homes. DTE Energy plans to replace them with renewable energy. The Detroit Free Press wrote that employees at the closing plants will be able to transfer to other facilities and will not lose their jobs.
Many of DTE Energy's coal plants were built in the 1950s and 1960s and "are nearing retirement age."
Since 2009, DTE Energy has invested over $1 billion in renewable energy according to their 2015 - 2016 Corporate Citizenship Report.
As of June 2016, DTE Energy plans to build a solar arrays in Lapeer, Michigan that will be one of the largest in the eastern United States. It will do so as it retires coal-fired generators at coal plants in Michigan. According to DTE Energy, it is the largest investor in renewable energy in Michigan. It has invested over $2 billion since 2008.
In May 2016, the company broke ground on a solar array project in Lapeer, MI touted as the largest utility-owned solar array east of the Mississippi River. When the project is completed, it is expected to generate enough electricity to power 9,000 homes. DTE Energy also broke ground on a 10-acre solar installation in Detroit on the site of the abandoned O'Shea Park.
In May 2017, DTE Energy announced it had acquired "two landfill-based gas-to-energy operations" in Texas. The company wants to expand its operations to alternative vehicle fuel. The operations it acquired were the Fort Bend Power Producers, LLC facility outside of Rosenberg, Texas and the Seabreaze landfill gas development in Angleton, Texas, which has yet to be developed.
After these projects are operational, the company will have five "landfill conversion facilities which capture and convert dangerous landfill gases to pipeline-quality renewable natural gas." The gases will go to fueling transit buses.
In December 2011, the non-partisan organization Public Campaign criticized DTE Energy for spending $4.37 million on lobbying and not paying any taxes during 2008-2010, instead getting $17 million in tax rebates, despite making a profit of $2.5 billion.
