PacifiCorp reaped well more than half the $26.16 million in gross benefits yielded by the Energy Imbalance Market (EIM) in the third quarter, CAISO said.

Last week's FERC technical conference on the EIM began on a contentious note but concluded with participants understanding each others’ perspectives.

The Sacramento Municipal Utilities District (SMUD) will join the Western EIM in spring 2019 at the earliest, according to the head of BANC.

CAISO is seeking stakeholder input on how to respond to a solar eclipse that will significantly curtail output from California’s growing solar generation portfolio next August.

The Sacramento Municipal Utility District will join the CAISO EIM and other members of the Balancing Authority of Northern California (BANC) may follow.

More changes are needed to the CAISO proposed rules for a Western RTO to win approval from the states in which PacifiCorp operates, stakeholders say.

CENACE and CAISO announced an agreement to explore the benefits of having Baja California Norte join the Energy Imbalance Market (EIM).

CAISO is seeking ways to ensure that the EIM governing body and participants, havea say in ISO policies that affect the EIM.

Environmental group Western Resource Advocates was an early proponent of CAISO’s Energy Imbalance Market and is actively supporting the ISO’s effort to transform itself into an RTO serving the broader West.

CAISO last week released the third draft of a proposal outlining the principles intended to underpin the governing framework for a Western RTO.
