Installing Generating Equipment

Electric Generating Equipment Considerations

Let us help you safely connect your electric generating equipment system with our electrical system.

To avoid property damage or personal injury, make sure you have properly isolated your home from our system before connecting portable generators for back-up or emergency power.

If you’re installing a permanent electric generating equipment such as solar or wind, or if you are installing an energy storage technology, state regulations subject all such systems operating in parallel with ours to be reviewed and approved.

How to Apply For Interconnection Service

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.

Indiana Customers

System Sizing

To be eligible for Net Metering Service under Rider NMS, your renewable energy facility must be less than or equal to 1,000 kW in capacity on a per meter basis and have projected annual renewable energy production that matches your annual kWh of load, also on a per meter basis.

Ownership and Location of Customer-Owned Renewable Facilities

Net Metering Service under Rider NMS requires that the customer own the renewable facility that is being installed. Further, the renewable energy facility must be installed at the premise where the customer is taking electrical service from I&M.

Key Interconnection Approval Dates for Net Metering Eligibility

I&M’s current Net Metering Service Program under Rider NMS has a few important dates relative to the status of your interconnection application that you should be aware.

Before July 1, 2022: Customer receipt of confirmation from I&M by June 30, 2022 that a complete Interconnect Service Application has been received by I&M documents eligibility under I&M’s current Net Metering Service Rider if there is capacity available under Rider NMS.

On or After July 1, 2022: Customer receipt of confirmation from I&M on or after July 1, 2022 that a complete Interconnect Service Application has been received by I&M will be compensated at a rate for excess distributed generation at a rate to be approved by the IURC.

Frequently Asked Questions

Expand the questions below to find answers to common questions on Net Metering Service eligibility in Indiana and the Distributed Generation Interconnection Application Approval Process.

Customers in good standing who own and operate an eligible net metering renewable energy resource designed to operate in parallel with I&M's system will be eligible for net metering credits at their current retail rate under Rider NMS.

To be eligible, the customer and their installer must ensure the renewable energy resource has a nameplate capacity of less than or equal to 1 MW dc (1,000 kW) in capacity with anticipated annual renewable energy production sized to match the customer anticipated annual kWh load on a per meter basis.

Further, to be eligible under Rider NMS, the customer must receive confirmation from I&M that a completed Application for Interconnection has been submitted via our PowerClerk online application platform by June 30, 2022. Net metering credits for these systems ultimately granted permission to operate will be provided until July 1, 2032.

Customers who receive confirmation that a completed Application for Interconnection has been submitted to I&M on or after July 1 will be able to sell excess generation from their renewable facility to I&M at a rate still subject to final approval by the IURC.

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.

Step 3: I&M verifies the proposed system is sized to match the annual customer kWh load and meets current net metering eligibility system design criteria.

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 for net metering eligibility, please make sure you and your installer reply to any requests for clarification during Steps 2 and 3.

Customer receipt of confirmation from I&M by June 30, 2022 that a complete Interconnect Service Application has been received documents net metering eligibility under I&M’s Rider NMS.

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 where the renewable energy resource will be interconnected that is collected during the installer site visit 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 system 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 then approves the project. If needed, I&M prepares construction agreement for the installation of new equipment the customer must pay for to safely operate in parallel with I&M’s system.

Step 7: The customer receives the Interconnection Approval and Construction Agreement (if needed) for new equipment to safely operate in parallel with I&M’s system and makes payment. The system 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 be able to operate the system when Steps 8-13 as summarized below are completed:

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

Step 9: I&M installs new equipment if needed after customer payment is received for the Construction Agreement. I&M then prepares the Interconnection Service Agreement for customer signature.

Step 10: The customer signs the Interconnection Service Agreement via DocuSign.

Step 11: I&M verifies that the system was installed as proposed and creates order to install the bi-directional meter.

Step 12: I&M installs the bi-directional meter.

Step 13: I&M issues Permission to Operate and net metering service rider credits are activated.

The customer is not permitted to operate the system until Permission to Operate has been issued by I&M in Step 13.

Your installer and you can request access to PowerClerk to review the status of your project by:

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 steps and project 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:
