Customer Data Privacy Policy

Last Modified: August 22, 2023

The Customer Data Privacy Policy was initiated at the request of the Michigan Public Service Commission for the protection of DTE Energy’s customer usage data and personally identifiable information. Its goal is to strike a reasonable balance between DTE’s collection, use or disclosure of any customer information to facilitate safe and reliable energy service. DTE Energy is complying with new legislative mandates addressing customer access to energy consumption data, and with customers' expectations regarding the collection, disclosure and use of their data and personal information.

We collect customer information based on our business relationship with you, your use of our utility services and other products we provide and use it in order to accomplish our primary purposes. Some examples include, but are not limited to:

  • Contact information including your name, address, telephone number and email address.
  • Billing and payment information, including your payment data, credit history, driver's license, state ID number and/or Social Security number.
  • Electric and gas usage data gathered by our metering systems measured in ccf, mcf, therms, dth, kW, kWh, voltage, var and/or any other energy measurement.
  • Personal information gathered when you choose to participate in utility programs or services, such as bill payment assistance, shutoff protection, renewable energy, demand-side management, load management and/or energy efficiency.
  • We may also supplement the information we collect from you with information from other sources such as (a) publicly-available information that we have purchased from third party sources, (b) information available on social media sites, and (c) data derived from our own enterprise data analytics.

DTE Energy will not disclose your information to third parties and other inquirers without your consent. A third party is a person or entity that has no contractual relationship with DTE Energy to perform services or act on behalf of DTE.

However, DTE may disclose your information to DTE agents and contractors working on behalf of the company, when it is necessary to provide electric or natural gas utility services to you without first obtaining your prior consent. DTE can disclose your information in emergency situations and as directed by any warrants, court orders or subpoena. The provision of such information will be reasonably limited to the amount authorized by law or reasonably necessary to fulfill a request compelled by law.

DTE Energy will not sell your information — except in connection with sales of certain aged receivables — to collection firms for purposes of removing this liability from its accounts.

Yes, you do have a right to know what information DTE Energy maintains about you, except for proprietary data or information which is used for internal business purposes only. We will make a reasonable effort to respond to your request within 10 business days following receipt of your request.
