Multiple disturbances that involve the widespread reduction
of solar photovoltaic (PV) resources have occurred in California and Texas. This report provides a comprehensive
assessment of a widespread loss of solar PV and synchronous generation caused by a normally cleared fault in the
Texas Interconnection that occurred on June 4, 2022 (referred to herein as the “2022 Odessa Disturbance”). This
event is unique in that NERC and Texas RE analyzed a nearly identical event that occurred just over one year prior at
the same location. This event is a perfect illustration of the need for immediate industry action to ensure reliable
operation of the BPS with increasing penetrations of inverter-based resources. The unexpected and unplanned loss of
generation (both synchronous and inverter-based) poses an
increasing and significant risk to BPS reliability.
