ERCOT NOGRR-245 Final Compliance Deadline is Approaching: December 31

While all IBR resource entities in ERCOT should have filed the ERCOT RFI DocuSign and requests for exemption/extension prior to April 1, 2025, the final compliance deadline of December 31, 2025, is rapidly approaching. If your projects fall into any of the following categories, the following steps still need to be completed in order to achieve total compliance:  

• Legacy Projects (SGIA signed before August 1, 2024): Projects that are confirmed capable of meeting NOGRR-245 by December 31, 2025, regardless of any granted exemption, but have not yet maximized ride-through capabilities. 
• Legacy Projects with Extensions: Projects granted an extension that still need to comply with NOGRR-245 by their extended deadline. 
• New Projects (SGIA signed after August 1, 2024): Projects that have not maximized ride-through capabilities or finalized inverter and BoP equipment ride-through settings. 
• New Projects with IEEE-2800 Extensions: Projects that were granted an extension for meeting IEEE-2800 Sections 5, 7, and 9. 

Most sites will need to: 

• Develop optimal ride-through settings: Ensure inverters, turbines, and substation equipment are configured to maximize ride-through capabilities. This not only involves inverter level setting change but also plant level TOV/TRV assessment to ensure substation protections are coordinated properly 
• Submit model packages: Provide ERCOT with a proposed model package demonstrating maximum ride-through capability before implementing any field changes.  
• Complete field implementation: Apply setting changes in the field by December 31, 2025, or by the ERCOT-granted extension deadline. 

Ensure your IBR facilities are prepared for the primary NOGRR-245 compliance deadline (December 31, 2025, or the ERCOT-granted extension date).
