NERC and the Regional Entities continue to analyze disturbances that involve widespread reductions of solar photovoltaic (PV) resources to identify any systemic reliability issues, to support affected facilities in developing mitigating measures, and to share key findings and recommendations with industry for increased awareness and action. The ongoing widespread reduction of solar PV resources continues to be a notable reliability risk to the BPS, particularly when combined with the additional loss of other generating resources on the BPS and in aggregate on the distribution system. This report contains the ERO analysis of four BPS disturbances with widespread reductions of solar PV output that occurred in the California Independent System Operator (CAISO) footprint between June and August of 2021.
