Amid increasing renewable energy integration and grid reliability challenges, ERCOT recently reiterated the importance of maximizing Frequency Ride-Through (FRT) and Voltage Ride-Through (VRT) capabilities for all Resources. This initiative ensures grid stability, even during widespread frequency or voltage disturbances. Following the approval of NOGRR245 on Sept. 26, 2024, and its effectiveness starting Oct. 1, 2024, ERCOT has emphasized full compliance with these updated requirements.
This article outlines the immediate actions required, approaching deadlines, and comprehensive compliance guidelines necessary for successful FRT and VRT implementation.
The updated requirements focus on ensuring that all Inverter-Based Resources (IBRs) and Type 1 and Type 2 Wind Generation Resources (WGRs) respond effectively during grid disturbances. Meeting these standards reduces the likelihood of event-driven cascading failures and strengthens long-term energy reliability in Texas’s evolving energy landscape.
ERCOT has stressed that simply meeting minimum ride-through thresholds is insufficient. Instead, resources must maximize their capabilities for greater grid resilience. Below, we’ll provide a breakdown of the new compliance framework and what you need to do to ensure alignment with it.
Maximize FRT capabilities to meet or exceed ERCOT’s Nodal Operating Guide (NOG) §2.6.2.1(1)–(5). Resources unable to meet these standards and have a signed SGIA before Aug. 1, 2024, must comply with the following steps:

Maximize VRT capabilities to meet or exceed IEEE 2800–2022 Sections 5, 7, and 9, as well as ERCOT NOG §2.9.1.1(1)–(7) (Preferred Curve). Resources unable to meet these standards and have a signed SGIA before Aug. 1, 2024, must comply with the following steps:
If the legacy curve cannot be met:
