May 2026 is the start, not the end.
Category 2 IBRs faced their first compliance deadline in May 2026. Eight O&P standards apply immediately. More are coming. Get ahead now.
NERC is rewriting standards to include IBR Category 2 facilities (20-75 MW wind, solar, and storage). The May 2026 deadline brought many new registrations under NERC oversight. Many GOs and GOPs saw their NERC fleet doubled.
The initial standards focus on operations and planning. CIP standards will follow as NERC continues revising requirements. The regulatory scope will only expand.

Waiting until standards apply means scrambling to build a compliance program under deadline pressure. Setting up early means you document your assets, establish workflows, and build audit relationships before the scrutiny begins.
Raptor Comply tracks which standards apply to your facilities and when. As NERC expands requirements, your platform expands with them.
