How to file an ERCOT interconnection request (GINR) in RIOO-IS
General information, not a substitute for the advice of an attorney.
Who grants it: ERCOT, through RIOO-IS (Resource Integration and Ongoing Operations, Interconnection Services), with the host transmission service provider running the studies.
When it applies: Generation of 10 MW or more at the point of interconnection, per Planning Guide 5.1.1 (smaller projects go through the utility's distribution process and still register). ERCOT publishes no county permit for this; the request is the approval path.
What the application asks for, and where to find it
| The application asks for | Where you find it | How |
|---|---|---|
| Interconnecting Entity (IE) account | The agency's website | Sign up in RIOO-IS with the IE sign-up guide. |
| Point of interconnection: substation or line, voltage | Your engineer | Your electrical engineer picks it from the transmission map; the report's "Nearest power line" row (HIFLD, kV) and the POI finder are the starting points. |
| Site coordinates, county, parcel | This site: the land report | The land report: coordinates and county (page 2), property ID (Lease page). |
| Technology, nameplate MW, inverter or turbine data | Your engineer | Equipment data sheets; stability model data follows later under Planning Guide 6.2. |
| Electrical one-line diagram | Your engineer | From the electrical design; the request and the Full Interconnection Study both use it. |
| Projected commercial operation date | You (the applicant) | Your schedule; compare with the schedule page. |
| Site control evidence | The landowner | The signed lease or option (the report's Lease page lists what it must contain); ERCOT and the TSP ask for proof of site control. |
| Fees and security | The agency's website | Amounts are in the ERCOT Fee Schedule in the Protocols and Planning Guide Section 5; the interconnection page keeps the sourced figures. |
What the "where you find it" column means
- This site: the land report
- Run the spot on the land report; the value is on the page named, with its agency source.
- Appraisal district (tax assessor)
- The county appraisal district record: property ID, legal description, acreage, owner of record, agricultural valuation. The report's Lease page links it; the Permits page lists the district's phone.
- The landowner
- Only the owner can supply it: signed authorization, deed reference, existing leases, access, their contact details.
- Your engineer
- From your civil or electrical engineer: site plan, disturbed acreage, drainage, the electrical one-line, nameplate and inverter data, structure heights.
- Surveyor or title company
- Boundary survey, legal description for recording, easements of record, title commitment.
- The agency's website
- The agency publishes it: forms, fee schedules, community numbers, district offices, portal accounts.
- You (the applicant)
- Your entity details: legal name, address, signatory, contacts, FEIN, insurance.
How to file it
- Confirm the request is required under Planning Guide 5.1.1 (Planning Guide).
- Create the IE account and submit the GINR in RIOO-IS, following the over-10 MW INR guide; pay the fees in the Fee Schedule.
- ERCOT screening study, then the election to proceed to the Full Interconnection Study run by the host TSP (the clocks are on the interconnection page).
- Execute the Standard Generation Interconnection Agreement (the Nov 6, 2025 form for agreements signed on or after Jan 1, 2026), then register as a Resource Entity.
Fees and clocks
ERCOT's page points to the Fee Schedule in the Protocols for all fees; the study clocks and deposits, with their sources, are on this site's interconnection page and schedule page.
The pages you will use
After you file
After the agreement: Quarterly Stability Assessment, model submissions, the commissioning checklist to RIOO-IS and CommissioningRequests@ercot.com, and Resource Asset Registration Forms before energization (all listed on the Resource Integration page).
