How to Apply For Interconnection Service in Michigan

Before you install your solar panels or other distributed energy resources, and before you connect to our grid, you'll need to submit an interconnection service application.

Once approved, you can install the system, and following a successful inspection of your equipment, you'll submit a signed agreement with us that governs the arrangement.

Check out our Frequently Asked Questions below for more information on our interconnection program.

Apply for interconnection


Michigan Customers

To be eligible for interconnection, customers must generate a portion or all of their own retail electricity requirement with an Eligible Electric Generator which utilizes a Renewable Energy Resource as outlined in I&M’s Distributed Generation Rider (DG Rider).

System Sizing

The Eligible Electric Generator systems and nameplate capacity limits are defined in the DG Rider for each type of system. The system must be located on the customer's premises, serve only the customer's premises and must be intended primarily to offset a portion or all of the customer's requirement for electricity. The nameplate capacity to generate electricity will be compared to the customer’s annual consumption of electricity in kWh on the premises on a per meter basis.

For eligible customers without adequate electricity use data, I&M can review projected load information to ensure the facility sizing is intended primarily to offset a portion or all of the customer's own electrical load requirements on a per meter basis, consistent with the nameplate capacity limits for each type of Eligible Electric Generator system.

Ownership and Location of Renewable Facilities

The customer need not be the owner or operator of the eligible generation equipment, but is ultimately responsible for ensuring compliance with all technical, engineering and operational requirements to operate in parallel with I&M’s distribution system.

Frequently Asked Questions

Expand the questions below to find answers to common questions on I&M’s Interconnection and Distributed Generation Program Application approval process.

I&M’s two net metering service riders - for customers with generating facilities of 20 kW or less (Rider NMS-1) or greater than 20 kW (Rider NMS-2) – are only available to eligible customers participating prior to February 1, 2020 as defined in the referenced riders.

All customers now on Rider NMS-1 and NMS-2 net metering will be grandfathered for 10 years from the date of their meter change following issuance of their permit to install under an approved Interconnection and Distributed Generation Program Application.

Any changes to existing net metering customer’s systems may lead to a loss of net metering eligibility under these riders. Further, customers eligible under Riders NMS-1 and NMS-2 have the option to take service under I&M’s current DG Rider as their 10 years of eligibility nears an end.

Customers participating after the previous net metering service rider deadlines are subject to the requirements of I&M’s DG Rider.

The installer, customer and I&M should complete Steps 1-4 as summarized below:

Step 1: The installer or customer register for access to PowerClerk. The installer or customer then submits the required application to I&M via PowerClerk.

Step 2: The customer then signs the application via DocuSign and pays the required application fee.

Step 3: I&M verifies the proposed system is sized to match the annual customer kWh load and meets current interconnection rider eligibility system design criteria under I&M’s DG Rider.

I&M also verifies all information in the application and requests and receives missing information from customer and or installer to ensure the application is complete and correct.

Step 4: The customer receives confirmation that a complete Interconnection Service Application has been received by I&M.

For the timely issuance of the confirmation that a complete Interconnection and Distributed Generation Program Application has been submitted, please make sure you and your installer reply to any requests for clarification during Steps 2 and 3.

Customers and their installers who submit an Interconnection and Distributed Generation Program Application via AEP’s PowerClerk online platform should focus on several key steps to ensure their Interconnection and Distributed Generation Program Application can be confirmed as complete by I&M in a timely manner.

The key mistakes that often create the most errors and delays in application processing include:

  • The customer’s account number is NOT entered exactly as instructed in PowerClerk
  • The customer’s name and address on the account is NOT entered into PowerClerk exactly as it is shown on the customer’s monthly invoice
  • The customer’s meter number is NOT entered exactly as instructed in PowerClerk
  • Records Fix requests provided by the I&M team via e-mail from PowerClerk or the DG Coordinator are NOT responded to and addressed in a timely manner

Please note, if you have a question about a required entry in the PowerClerk online application form, just click on the Question Mark (?) near the entry for guidance.

Once a customer receives confirmation from I&M that a completed Application for Interconnection has been submitted in Step 4 of the process indicated above, the customer will be issued an Interconnection Approval to build the eligible distributed generation facility when I&M completes Steps 5-7 as summarized below:

Step 5: I&M conducts a review of project’s impact to the distribution system. Note that< 5% of projects typically require a reliability study/system review by I&M.

Step 6: I&M conducts the review (or reliability impact study, if needed) and prepares a construction agreement for the installation of new I&M equipment, if necessary. I&M will install the new equipment after the customer signs the Construction Agreement and customer payment is received.

Step 7: The customer receives the Interconnection Approval notification and the eligible distributed generation facility can now be constructed by the installer as proposed.

For the timely issuance of the Interconnection Approval, please make sure you and your installer reply to any requests for clarification, signature and or payment, as needed, during Steps 5-7.

Once a customer receives the Interconnection Approval confirmation from I&M in Step 7 indicated above, the customer will then be able to install their system. Steps 8-12 will need to be completed as summarized below before permission to operate will be given.

Step 8: The installer constructs the system and provides proof of installation and local inspection to I&M via upload in PowerClerk.

Step 9: The customer signs the Interconnection Service Agreement via DocuSign.

Step 10: I&M verifies that the system was installed as proposed and creates order to install the bi-directional meter.

Step 11: I&M installs the bi-directional meter. Normal time frame for meter changes is 7-10 business days.

Step 12: I&M issues Permission to Operate and updates customer account for interconnection and applicable credits for power delivered to I&M.

The customer is not permitted to operate the eligible distributed generation facility until Permission to Operate has been issued by I&M in Step 12.

Your installer can grant you access to PowerClerk after you register for PowerClerk by granting you Read Only or Read/Write under the Access Grants for this Project. The installer will need a valid email address for you.

All of us have experienced at times frustration when e-mail client spam and junk filters block important e-mails we need. This can happen at times with e-mails from Power Clerk and I&M’s shared mailboxes used to manage application communications.

I&M recommends that you check your spam and junk folders often after your application is submitted to avoid missing communications from us. Common email addresses issued by PowerClerk and I&M include:

An initial Application for Interconnection must be submitted via PowerClerk at https://aep.powerclerk.com and must include uploads of the following information:

  • A site location map,
  • An electrical one-line diagram showing the configuration of the proposed distributed generation facility. Facilities over 50 kW in nameplate capacity must have the electrical one-line diagram stamped by a licensed Professional Engineer,
  • A series of site pictures that demonstrate the location of panel installation, the current electrical meter, and the area surrounding the current electrical meter up to 2 feet in all directions, and
  • Specification sheets for all equipment proposed to be installed.

Once your eligible distributed generation facility is approved for installation and constructed per Steps 7 and 8 above, you will need to upload the following documents to Power Clerk:

  • A copy of the local building inspection report
  • A letter from the licensed electrician attesting that the generation equipment has been installed in accordance with applicable local and National Electric Code requirements (if no local permit inspection authority exists)
  • Digital pictures of
    • The installed generation equipment,
    • The AC disconnect,
    • The inverter nameplate,
    • The utility meter, and
    • All required placards under National Electric Code requirements.

In order to obtain permission to install and ultimately operate an Eligible Electric Generator system for a Renewable Energy Resource under I&M’s DG Rider, a customer shall submit a completed Interconnection and Distributed Generation Program Application. This application requires payment of a $50 application fee.
