Building for tomorrow means changing how we generate power for our 2.2 million electric customers. DTE is heavily investing in cleaner, efficient, Michigan-made renewable energy. Since 2009, DTE has driven investments of more than $2.8 billion in renewable energy, and the company will invest an additional $2 billion in renewables over the next five years as it more than doubles its wind and solar generating capacity. By 2022, DTE will generate enough energy from renewable resources to power more than 800,000 homes.

The energy of tomorrow does not come together overnight. Renewable energy projects often take years of research, planning and development before they are commissioned.

Wind Energy

Wind development can take up to five years for signing land easements, siting, zoning, feasibility and environmental studies, permits, and construction and involve more than 200 permits from local, state and Federal agencies. The size of a wind park depends on the area of land available, additional electrical demand required and available electrical system capacity.

These are the steps our renewable energy team takes when developing a wind park:

  1. Obtaining Land Easements
  2. Collect Wildlife and Other Data
  3. Apply for Electrical Interconnection
  4. Identify Turbine Locations
  5. Secure Permits
  6. Procure Turbines and Other Components
  7. Construct Access Roads
  8. Pour Foundations
  9. Install Turbines and Other Components
  10. Complete Substations and Interconnections
  11. Test Turbines
  12. Commission and Operate Wind Park

The renewable energy development team also continuously seeks community feedback through multiple meetings and open houses, performs wildlife studies for up to three years, collects wind resource and weather data, reviews local zoning and permitting requirements and more.  

Solar Energy

Siting and permitting a solar array is a complex process as well. AT DTE, we provide detailed project construction and installation plans, conduct numerous environmental studies, collect data on the sun’s rays in certain areas and develop plans to connect solar arrays to our energy grid. Since most solar arrays are located on privately-held lands, various state and local agencies must grant the necessary approvals before construction can begin.

DTE Major Enterprise Project Construction Manager Paul Lisecki said you need “a good contractor, a good engineering firm and a really good plan,” to commission a solar array.

DTE’s investment in renewable energy is part of DTE’s larger plan to reduce carbon emissions by more than 80 percent by 2040. A healthy environment and a healthy economy – we believe we can have both.
