There are two submission paths: DocuSign for resources with production load dates and RIOO for projects without.
The RIOO process is project-based and includes a downloadable GIM interconnection template for those seeking exemption or extension.
Projects in the interconnection queue do not need to respond unless they seek exemption or extension and meet specific criteria such as being a generation resource or energy storage resource.
Instructions for completing the RIOO submission include filling out a DOCX template and creating a ZIP file with all referenced documents for each project.
The deadline for the submission is by midnight on April 1, 2025.
There was an issue with DocuSign envelopes being sent to authorized or backup representatives; it should now be resolved.
Exemptions and extensions have a strict submission deadline; no extension to the April 1 deadline is available for the initial request submission.
ERCOT will review extension or exemption requests post-submission for completeness and accuracy.

ERCOT received questions on modification plans and next steps for maximizing unit capabilities.
Major modifications require the generation interconnection process; small modifications affecting dynamic response undergo PGRR109 model review.
PGRR109 ensures compliance with FAC-002-4 standards and addresses historically unacceptable IBR events.
Dynamic model submission is required before resource commissioning and after any changes.
For operations, modifications require following the PGRR109 model review process before field implementation.
Model performance is checked against quarterly stability assessment results.
Clarity sought on handling post-maximization model submissions and determining modification process timelines.
Projects must undergo the PGRR109 process if changes affect dynamic response, with final submissions due post-implementation.
Operation guide extensions require ERCOT review time allowances, with extensions requested if unable to meet deadlines.
Submissions for the April 1 deadline must include pre- and post-maximization models if seeking exemptions.
Discussion on model submission, extension requests, and coordination with TSP for dynamic stability studies.

ERCOT aims to accurately respond to questions but notes that official guides prevail over staff answers.
