What is being proposed

This modification includes supplementary sections designed to facilitate intentional islanding during the process of system restoration.

Details

Analysis

EREC G99 adds supplementary sections to facilitate intentional islanding during system restoration. This is a code modification to the distribution connection standard. The change enables grid-connected assets to operate in isolation when the grid is being restored after blackouts.

Why it matters

This addresses a real operational need — enabling distributed generation to support restoration — but the specifics are too limited to assess properly. Without details on which assets qualify or how islanding decisions get made, this could either streamline recovery or create coordination problems.
