Summarizing the findings from its 2025 Level 2 alert on large loads, NERC warned most entities have not met its recommendations.

NERC said the response to an alert from June 2024 shows many generator owners do not have available, up-to-date information on the capabilities of their inverter-based resources.

NERC is requesting a range of information on inverter-based resource modeling because of a series of grid disturbances in recent years.
