Three major IBR compliance milestones converged in a single 60-day window this spring. Here’s where things stand on NERC registration, PRC-029-1, MOD-026-2, and PJM’s IEEE 2800 adoption — and what generator owners must do right now.

FERC's approval of MOD-026-2 and the Milestone 3 standards package marks the most significant restructuring of IBR compliance obligations since Order 901, introducing mandatory EMT model cross-validation and a four-year runway to full compliance by April 2030.

Three new IBR performance standards are heading toward enforcement with hard deadlines in late 2026 and early 2027, while MOD-026-2's EMT modeling mandate is already live. Here's your compliance action plan.

FERC approved Milestone 3 reliability standards for IBRs on April 11, 2026 — completing the Order No. 901 compliance framework with enforceable EMT modeling and validation requirements.

Analysis of FERC's landmark RD26-1/2/3 approval establishing enforceable IBR data sharing and dynamic model validation requirements across the bulk electric system.

Comprehensive analysis of FERC Order 901's IBR reliability standards, including filing deadlines, compliance requirements, and implementation timeline through 2026.

The May 2026 NERC IBR registration deadline is approaching. Learn what Category 2 owners need to do now to ensure compliance with new reliability standards.

AI-era data centers behave like “electrified factories”: large, often fast-ramping, and increasingly colocated with generation.

Southwest Power Pool (SPP) is proposing a modeling package that must be submitted at the time of interconnection request.

ERCOT’s Model Quality Tests (MQT) are a formal set of dynamic simulations and evidence reports.

Short-circuit ratio (SCR) is a compact way to express “system strength”—how stiff the grid voltage looks to a device at its point of interconnection (POI).

GridStrong is scaling to help asset owners manage compliance with confidence.

Utility-scale inverter-based resources (IBRs)—wind, solar PV, and batteries—now sit at the center of grid reliability policy.

Translate data center reliability risks into utility-ready models: powerflow, EMT, short-circuit & harmonics.

Conventional turbine-generator shafts have very low inherent torsional damping.

AI data centers aren’t “just loads”—fast ramps, ride-through, and power quality create new grid reliability risks.

PRC-029 sets critical ride-through requirements for inverter-based resources (IBRs).

PRC-028-1 & ERCOT NOGRR 255 demand SER, FR & DDR—know what to record and how to pass audits.

PRC-029-1 makes IBR ride-through performance-based—unify design, models, and events to stay compliant.

PJM’s MOD-026/027 guidance sets new IBR modeling expectations—get ready now for MOD-026-2.
