?? ERCOT NOGRR-245 Compliance & Analysis – We’ve Got You Covered! ?? With the Public Utility Commission of Texas approving NOGRR-245, revised ride-through requirements are now in effect, and Registered Entities (REs) and Interconnecting Entities (IEs) must submit required data to ERCOT by April 1, 2025. Compliance depends on a resource’s operational status, requiring a tailored submission process.—ensuring compliance is critical for grid stability and operational reliability. At I2R Grid Solutions, Inc. we specialize in: ? Power System Model Development & Validation ? Steady-State & Dynamic Studies ? ERCOT Compliance Support & Reporting With deep expertise in power systems modeling, transient analysis, and ERCOT regulatory requirements, we help generators and market participants stay compliant while optimizing performance. Need support? Let’s talk! Comment below or DM Sachin Soni to discuss how we can help your team navigate these changes. #ERCOT #NOGRR245 #GridReliability #PowerSystems #Compliance #RenewableEnergy #EnergyConsulting #I2RGridSolutions

**IBR models (PSCAD and PSS/E) are critical for renewable energy developers to demonstrate compliance with ERCOT’s grid operation standards. **New PGRR-109 Requirement** Previously, ERCOT allowed you to submit your as-built dynamic model within 30 days of starting commercial operation. But as of May 1, 2024, a new requirement prohibits you from claiming commercial operation without providing the model beforehand. Failure to comply means you cannot begin commercial operations or participate in ERCOT’s energy market. https://lnkd.in/gjUsKJh2 **Why As-Built Models Matter** ERCOT relies on accurate as-built dynamic models to enhance grid planning and operation. The PGRR-109 requirement ensures IBR entities provide accurate models, holding them accountable. **Staying Compliant** Managing as-built dynamic models is complex. It requires cohesive management from project planning through commissioning and testing to ensure compliance with ERCOT standards. **Key Parameter Verification Report (PVR) Information** Even though the ERCOT PVR is still due within 30 days after the COD, it is very important to make sure that the field parameters match the model parameters during the commissioning stage before COD. You can achieve this by making sure the model parameters studied during the QSA model are entered into the PPC/Inverter during the commissioning process. This is important so that once the commissioning is completed and approved by ERCOT, a PVR showing matching parameters can be completed within the required 30 days **I2R Grid Solutions Can Help!** Our ERCOT experts have years of experience in as-built model development, ensuring you meet the latest requirements without delays. Don't hesitate to reach out should you need support on your project(s).

ERCOT issued a Market Notice yesterday. Source: https://lnkd.in/g3Vg6q7W to all Resource Entities with inverter-based resources - solar, wind, batteries - to implement software, firmware, controls, and protection system and parameter changes to maximize plant ride-through performance. This involves conducting a ride-through performance assessment to attempt to move ride-through to exceed beyond current ride-through performance requirements and aligns with the previous 2023 NERC Alert for IBR performance issues. Source: https://lnkd.in/g_Bfs9wB ERCOT requested all Resource Entities to report by August 1, 2024 their plans (including a schedule) for implementing these changes, and encouraged Resource Entities to work with their original equipment manufacturers (OEMs) to assess and implement changes, where possible. Please don't hesitate to reach out to the I2R Grid Solutions, Inc. team. Our experts possess extensive experience in working with Resource Entities and OEMs. We specialize in assessing ride-through settings and parameters, conducting performance simulations, and reporting ride-through capability.
