Teleconference: Meeting Registration
NERC is hosting an informational webinar to share the key findings and recommendations from the recently published Odessa Disturbance Report and raise industry awareness of the analysis of solar photovoltaic (PV) disturbances.
On May 9, 2021, the Texas Interconnection experienced a widespread reduction of over 1,100 MW of solar PV resources due to a normally fault on the bulk power system. While the ERO has analyzed multiple similar events in California, this is the first disturbance involving a widespread reduction of solar PV resources in the Texas Interconnection. The event involved facilities across a large geographic area of up to 200 miles from the location of the initiating fault. There were multiple causes of power reduction from the affected facilities; however, the causes appear to be systemic in nature and closely match the similar types of disturbances that have been analyzed in California. A second, smaller event involving solar PV resources subsequently occurred in Texas on June 26. NERC and Texas RE analyzed both events, in coordination with ERCOT, and documented the key findings and recommendations in the report. The report provides details regarding the initiating event, performance of the bulk power system-connected solar PV fleet during the event and additional details around the event. The report also describes modeling and studies improvements needed to address the root causes of these issues, which is applicable to all Interconnections. The report lays out strong recommendations for the electric industry regarding mitigating these abnormal performance issues.
