California's governor demanded an investigation into the cause of a series of power outages — the first since since an energy crisis in 2001 — that blacked out parts of the state in recent days. California Independent System Operator (CAISO) has struggled to ensure reliability since Aug. 14, when, amid triple-digit temperatures, it declared a statewide Stage 2 Emergency, warning power outages were possible. Later that day — at 6:36 p.m. — citing 1 GW of lost generation capacity and an ensuing "extraordinary strain on the ISO electric system," CAISO escalated the event to a Stage 3 Electrical Emergency and initiated rotating outages throughout the state. The rolling outages were the state's first in nearly 20 years.
