Gridstrong's Approach to PRC-029-01

BUILD A RELIABLE EVENT DETECTION PROCESS

PRC-030-1 starts with a documented process for identifying unexpected changes in Real Power output from inverter-based resources. GridStrong ingests plant SCADA and historian data, applies your thresholds, and automatically flags events that meet PRC-030-1 criteria—without waiting for a disturbance report or manual review. Every detection is logged with the evidence you’ll need for an audit.

STANDARDIZE ANALYSIS & ROOT-CAUSE WORKFLOWS

Each flagged event needs timely analysis and documentation. GridStrong walks engineers through a structured workflow: characterize the event, document ride-through performance, capture reactive power response, and record root causes. Templates keep analyses consistent across plants, units, and OEMs, while a single system of record keeps you ready for requests from the RC, BA, or TOP.

TURN FINDINGS INTO ACTIONABLE CAPs

When performance issues are identified, PRC-030-1 requires Corrective Action Plans or technical justification. GridStrong streamlines CAP creation, assignment, and tracking—from setting priorities and owners to documenting OEM coordination and implementation status. Progress is visible at the fleet level, reducing the risk of missed follow-ups or aging open items.

DON’T GET CAUGHT BY UNEXPECTED IBR EVENTS

Unexpected ride-through behavior from inverter-based resources can trigger major power swings—and now, new compliance risk. PRC-030-1 requires Generator Owners to systematically identify sudden changes in Real Power output, analyze each qualifying event, and mitigate performance issues. GridStrong gives you a single platform to manage that lifecycle across solar, wind, storage, and hybrid plants—before enforcement dates and audits arrive.

PRC-029-01 FAQs

What is PRC-030-1?

PRC-030-1 is NERC’s “Unexpected Inverter-Based Resource Event Mitigation” standard. It requires Generator Owners to identify, analyze, and mitigate unexpected changes in Real Power output from inverter-based resources, and to document that process for compliance.

Who does PRC-030-1 apply to?

PRC-030-1 applies to Generator Owners with inverter-based resources connected to the Bulk Electric System and certain non-BES IBRs above defined capacity thresholds. If you own solar, wind, storage, or hybrid facilities connected at transmission-level voltages, you are likely in scope.

How is PRC-030-1 different from PRC-029-1?

PRC-029-1 focuses on ride-through performance requirements during system disturbances. PRC-030-1 focuses on what happens after those events—detecting unexpected IBR power changes, analyzing performance, and addressing any issues through corrective actions.

What counts as an “unexpected event” under PRC-030-1?

The standard targets sudden changes in Real Power output above specified thresholds over a short time window (for example, complete loss of plant output or large step changes). Normal dispatch, planned outages, resource ramping, and changes due solely to primary energy variability (like sun or wind) are generally excluded.
