Idaho Power and Powerex began transacting in the EIM, bringing to eight the number of members participating in CAISO’s regional real-time market.

Operators of traditional resources say the Vision 2030 paper drifts outside CAISO’s purpose of assuring reliability and managing markets.

FERC approved CAISO’s agreement for integrating Canadian power marketer Powerex into the EIM.

The CAISO proposal to provide transmission revenue to balancing authority areas that wheel power received a wary response from EIM stakeholders.

FERC staff have accepted CAISO’s implementation agreement for Powerex to join the EIM but cautioned that the arrangement could be subject to further scrutiny.

Powerex has signed an agreement with CAISO to become the first non-U.S. participant in the Western Energy Imbalance Market (EIM).
