The Texas electrical grid, managed by the Electric Reliability Council of Texas (ERCOT), is a dynamic and complex system. As renewable energy sources, particularly wind and solar, expand their footprint, ensuring grid stability becomes more of a challenge. In this context, ERCOT’s Nodal Operating Guide Revision Request (NOGRR) 245, which focuses on Inverter-Based Resource (IBR) Ride-Through Requirements, represents a significant regulatory development. Approved and effective as of October 1, 2024, NOGRR 245 is not just a technical update; it’s a fundamental shift in how wind farms, solar plants and other IBRs operate within ERCOT. It has important implications for both existing renewable assets and for future projects still in development.
