Interconnection Process

Interconnection Process

Safety Is Always in the Plan to Generate Electricity

Solar panels should be installed in accordance with all local codes and regulations. Take the time to review the safety features available for your system.

Getting Started

We know that installing a private solar system is a big commitment. While DTE will not be designing or installing your system, we will be working with you and your installer throughout the interconnection process. DTE looks forward to working with you to get your system connected safely to the grid.

Initial Steps

  1. Review the interconnection process illustration.
  2. Determine project size and review interconnection requirements.
  3. Navigate to the Electric Service Installation Guide (Green Book, a/k/a Service Installation Manual) and review Section 5 (Service Equipment) and Section 7 (Wiring and Appliance Installation).
Category Project Size Application Fee Requirements
1 Projects equal to or under 20kW $50 Category 1
2 Projects greater than 20kW but less than or equal to 150kW $50 Category 2
3 Projects greater than 150kW but less than or equal to 550kW $150 Category 3
4 Projects greater than 550kW but less than or equal to 2MW $250 Category 4

Roles and Responsibilities
DTE’s goal is to help you and your installer complete the interconnection process safely and with minimal delays. Please follow the process as outlined here and submit all requested materials in a timely manner to keep your project on track.

Customer Responsibilities
You and your installer are responsible for coordinating the design, installation, operation and maintenance of your private solar system. You are also responsible for following all applicable governmental laws and regulations (local, state and federal) as well as the requirements of DTE Electric's tariffs and rules, which includes a requirement for an externally located, readily accessible, and taggable disconnect switch. Please reference Section 5 and Section 7 of the Green Book.

DTE Responsibilities
DTE is responsible for meeting all required steps necessary to process your interconnection application in a timely manner. If you have any questions regarding the technical aspects of the application, please contact the interconnection hotline at 313.235.4333 or email the interconnection team at interconnect_account@dteenergy.com.

Completing the Interconnection Process
Once your construction documents are approved and your Parallel Operating Agreement has been signed, your project will be placed into a site visit queue. It is required that your system must remain OFF until DTE conducts the appropriate tests, configures your meter and completes the site visit.

Safety
DTE's top priority is the safety of its customers and employees. All private solar systems should be installed in accordance with all local, state and federal codes and regulations. Approval by DTE Electric and your local municipality are both required for safe operation of your system.
