CAISO's Board of Governors and the Western Energy Imbalance Market Governing Body approved an extended day-ahead market for the WEIM, calling it a milestone.

CAISO released a draft report on Western regionalization that is intended to revive talks on the ISO becoming a multistate RTO and bolster legislation.

A new legislative push for multi-state CAISO governance and the ISO's drive to add an extended day ahead market top this year's agenda.
