How to Access the Generator Interconnection Application (GIA) Portal

Views:

The new Generator Interconnection Application Portal is now live in the MISO Help Center. It should be used for submitting and managing all new applications. A data migration is currently underway to transfer historical applications from the old Grid Unity Portal to the new one. Until this process is complete, previously submitted applications will remain accessible and manageable through the old Portal. However, all new applications must be submitted via the new Portal.

To access the Portal as an Interconnection Customer, follow the step-by-step instructions below.

1. It is recommended to use Chrome or Edge as your browser to access the GIA Portal.

2. Go to the MISO Help Center and click Sign In in the upper right corner. If instead of "Sign In" you see "Hello, YourName!", you are already logged in and can go directly to Step 4.

3. Enter your email and password and click Sign in. If you do not have a Help Center account, follow the instructions in the How to Create a Help Center Account Knowledge Article to create an account.

4. Once you are signed in, click Hello, Your Name and select Profile from the drop down.

5. From the User Type drop down, select Interconnection Customer and click Update. Note: Once you make a User Type selection and click Update, the user type can't be changed unless you submit a request to MISO.

6. Refresh your browser, then click the Generator Interconnection tab and select GI Dashboard.

Note: You can only belong to one TO company at a time within the GIA Portal. If you want to see a different TO company's applications, you must first be deactivated from the current company in the GIA Portal and then added to the other company.
