4/1/2025

Applicable Resources must maximize performance of protection systems, controls, and other plant equipment to meet/exceed NOG §2.9.1.1(1)-(7) or IEEE 2800-2022 §§5, 7 and 9 (as applicable) [See, NOG §§2.9.1(8); 2.9.1.1(8); 2.9.1.2(8)]

As soon as practicable but no later than 12/31/2025 or COD

Type 1/Type 2 WGRs not required to meet/exceed capability and performance requirements in IEEE 2800-2022 §§ 5, 7 and 9 but must meet or exceed VRT requirements in NOG §2.9.1.2 [See, NOG §2.9.1(7)]

12/1/2025

Applicable Resource with SGIA before 8/1/24 that cannot meet NOG §2.9.1.2(1)-(7) by 12/31/25 after maximizing performance of protection systems, controls, and other plant equipment (even with extension) must submit Initial VRT Capability Report (IVRTCR) and notice of intent to request exemption [See, NOG §2.9.1.2(9)]

4/1/2025

Applicable Resources must inform ERCOT of date they fully maximized FRT/VRT capability to equipment limits to meet/exceed NOG §2.6.2.1(1)-(5), IEEE 2800-2022 §§5, 7 and 9, NOG §2.9.1.1(1)-(7), or NOG §2.9.1.2(1)(-(7) (as applicable)
[See, NOG §§2.6.2.1(6); 2.9.1(8); 2.11(3)]

Upon maximization

Applicable Resource that believes it: (i) already maximized FRT/VRT capabilities to meet/exceed applicable requirements, or (ii) will maximize FRT/VRT capabilities to meet/exceed performance requirements before 12/31/25, must submit accurate models reflecting field settings consistent w/ requirements for model updates in Protocols and Other Binding Documents [See, NOG §2.11(1)]
