1. Engineering Review: 
   • Detroit Edison: We will determine the parameters of the Engineering Review Study and inform you when we receive the waiver from the MPSC. After receiving the waiver from the MPSC, we will perform the study to determine the impact of your project on our electric distribution system. We will determine if any system modifications are required for safe and reliable interconnection of your project. We will inform you of the Engineering Review results and potential impacts to your schedule or project. We will make the necessary system modifications and approve your application allowing you to proceed with installation (not operation).
2. Parallel Operating Agreement:
   • Detroit Edison: The Parallel Operating Agreement (POA) will cover contractual issues such as, design, testing, maintenance, operation, modification of facilities, rate information, defaults, remedies, and liability. The customer checklist must be completed and a POA (available on the Web site) must be fully executed through signature of both parties prior to your project operating in parallel with the Detroit Edison system. At this time, Detroit Edison will also need to obtain proof of an electrical inspection by the appropriate city/township.
   • Customer: Review, sign and return the applicable POA and customer checklist. Also, send Detroit Edison proof of your city/township electrical inspection. Upon utility receiving all materials, contact the appropriate DTE Energy representative (you may also call 313.235.4333) following your installation to perform the customer generation site verification.
3. Customer Generation Site Verification:
   • Customer: Provide us with advance written notice five (5) business days before your project will be ready for inspection, testing and approval.
   • Detroit Edison: After we have your completed POA and customer checklist, we will schedule for a site visit to verify that you can safely operate in parallel with our system. This may include various tasks such as an anti-islanding test, changing meters, verification of proper installation of the isolation device, and verification of electrical city/township inspection.
   • Customer: The customer or project developer does not have to be at the site. If you choose to be at the site, please contact the appropriate DTE Energy representative you are working with on the project to schedule the visit .
4. Parallel Operation Authorization and Ongoing Operation:
   • Detroit Edison: Upon successfully verifying that your system can safely operate in parallel with our system we will sign and provide you with a copy of the fully executed POA. We will also send you an e-mail/letter notifying you that you are approved for parallel operation and may begin to operate in parallel.
   • Customer: Maintain current contact information with Detroit Edison. Any questions or change in your customer generation project, such as equipment change, please contact the customer generation hotline at 313.235.4333.
