How to Apply For Interconnection Service in Indiana

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


Indiana Customers

Interconnection agreements are available to Indiana customers in good standing who submit a complete Application for Interconnection to own and operate an eligible distributed generation facility such as solar photovoltaic, wind, biomass, or hydroelectric power. Eligible distributed generation facilities must be designed to operate in parallel with I&M’s system. Customers must also take service from I&M under an applicable standard service tariff.

Applications for Interconnection submitted after June 30, 2022 must meet the requirements outlined in I&M’s Excess Distributed Generation Rider (Rider EDG), while Applications for Interconnection received by I&M on or before June 30, 2022 deemed complete will be eligible for interconnection approval under I&M’s now-grandfathered Net Metering Service Rider (Rider NMS).

Plug-in electric vehicle (PEV) owners taking advantage of I&M’s Residential Service Plug-in Electric Vehicle (RS-PEV) Tariff or General Service Plug-in Electric Vehicle (GS-PEV) Tariff may not operate under Rider EDG.

Distributed Generation Facility Sizing

Under Rider EDG, your eligible distributed generation facility must be operated in parallel with I&M’s system and sized at a nameplate capacity of the lesser of 1,000 kW or a size projected to not exceed the customer’s average annual consumption of electricity in kWh on the premises on a per meter basis.

For eligible customers without historical electricity use data, I&M can review projected load information to ensure the facility sizing is intended primarily to offset all or part of the customer's own electrical load requirements on a per meter basis up to 1,000 kW.

Ownership and Location of Distributed Generation Facilities

Under Rider EDG, the customer must own and operate the eligible distributed generation facility located on the customer's premises.

Frequently Asked Questions

Expand the questions below to find answers to common questions on I&M's Interconnection Application Approval Process.

A customer that installed a net metering eligible generating facility prior to January 1, 2018 will receive credits for power delivered to I&M until July 1, 2047 under the terms of the net metering tariff in place on December 31, 2017.

A customer that either installed a net metering eligible generating facility on or after January 1, 2018 and before June 30, 2020, or submitted an Application for Interconnection deemed complete on or before June 30, 2022 by I&M, will receive credits for power delivered to I&M following permission to operate until July 1, 2032 under the terms of Rider NMS.

For either scenario above, a new property owner can choose to continue to be served under the terms and conditions of the applicable net metering tariff. In this scenario, the new property owner must sign a new interconnection services agreement with I&M.

It is important to note that any changes to existing net metering eligible customer system design may lead to a loss of net metering eligibility. Applications for Interconnection submitted after June 30, 2022 or that were not deemed complete by I&M by June 30, 2022 will receive credits for excess distributed generation delivered to I&M following permission to operate under I&M’s Excess Distributed Generation Rider (Rider EDG).

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 Interconnection Service Application to I&M via PowerClerk.

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

Step 3: I&M verifies the proposed distributed generation facility is designed to meet Rider EDG requirements.

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 Application for Interconnection 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 Application for Interconnection via AEP’s PowerClerk online application platform should focus on several key steps to ensure their Application for Interconnection 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 above, the customer will then be able to install their eligible distributed generation facility. Steps 8-12 need to be completed as summarized below before permission to operate will be given:

Step 8: The installer constructs the eligible distributed generation facility and uploads all required proof of installation and local building inspection documents to I&M via PowerClerk.

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

Step 10: I&M verifies that the eligible distributed generation facility 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 the customer’s to activate the 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,
  • Specification sheets for all equipment proposed to be installed, and
  • Evidence of homeowners, commercial, or other insurance providing coverage in the amount of at least $100,000 for the liability of the insured per the terms of Rider EDG.

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.

It depends on the proposed size of your eligible generating facility. For eligible distributed generation facilities with nameplate capacity of 10 kW or less there is no fee. For eligible distributed generation facilities with nameplate capacity of between 11 kW and 1,000 kW, the fee is $50.00 plus $1 per kW of nameplate capacity.
