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.

CAISO officials on Wednesday urged California lawmakers to pass legislation that would convert the grid operator into an RTO.

A key California lawmaker is seeking comment this week on a revived effort to regionalize CAISO and create a multistate Western RTO.

The Energy Imbalance Market (EIM) expanded its footprint and ambitions in 2017 while new suitors lined up to compete with CAISO as the vehicle for a Western RTO.

Legislature ended its 2017 session, drawing criticism for its pursuit of CAISO regionalization and for letting a 100% clean energy bill die in committee.

California legislation that would regionalize CAISO and mandate 100% zero-carbon retail electricity sales statewide by 2045 will not pass this year.
