A key California lawmaker introduced a bill to allow CAISO to become a Western RTO by expanding its governance to include representatives from other states.

A new coalition of trade and environmental groups says California must be in an RTO, bolstering a renewed push for CAISO to become a multistate organization.

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.

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 issued its final plan to add a day-ahead market to its real-time Energy Imbalance Market, and PacifiCorp said it would join if the plan is approved.

Energy leaders from California and other Western states met in a workshop to explore the benefits of developing regional markets, including one or more RTOs.

An extended day-ahead market for CAISO's Western Energy Imbalance Market could produce up to $1.2 billion annually for Western participants, a new study found.

FERC Chair Richard Glick made his first in-person visit to SPP’s headquarters last week, joining stakeholders for their regular quarterly governance meeting.

CAISO began a stakeholder process under ACR 188, a legislative request to examine the economic and environmental benefits of regional cooperation in the West.

SPP has posted its Markets+ draft service offering that lays out the RTO’s proposal to “modernize and enhance” the western grid’s operation.
