CAISO's revised plan for a WEIM extended day-ahead market makes changes to transmission requirements and penalties for failing resource sufficiency evaluations.

Former CPUC President Loretta Lynch said Ca. should review the rolling blackouts of mid-August and potential market manipulation in CAISO.

A report on the causes of California’s August blackouts contends that constrained transmission prevented much needed imports from reaching the state.

Observers cited dependence on imports, underperformance of natural gas and wind, and market manipulation as possible causes of California’s recent blackouts.

PGE (NYSE: POR) said it suffered $127M in losses from wholesale electricity trades due to recent volatility in California's energy market.

CAISO said millions of residents could be blacked out this week because it does not have enough power to meet demand during the heat wave.

CAISO’s internal Market Monitor provided more details about the extreme day-ahead price spikes occurring over a three-day period in June.
