Avian Flu Diary: The NERC 2022 Summer (Electrical Grid) Reliability Assessment

While NERC’s risk scenario analysis shows adequate resources and energy for much of North America, the Western Interconnection, Texas, Southwest Power Pool (SPP), and Saskatchewan are at “elevated risk” of energy emergencies during extreme conditions. Midcontinent ISO (MISO) is in the “high risk” category, facing capacity shortfalls in its north and central areas during both normal and extreme conditions due to generator retirements and increased demand. Additionally, at the start of the summer, MISO will be without a key transmission line connecting its northern and southern areas as restoration continues on a four-mile section of a 500 kV transmission line that was damaged by a tornado in December 2021.
