Plans to join PacifiCorp with CAISO grid move closer to reality

The integration of PacifiCorp as the ISO’s 17th transmission-owning member was set in motion by a memorandum of understanding signed in April. The MOU set up a joint feasibility study of the plan to incorporate the Warren Buffett-owned regulated utilities into the only competitive wholesale market in the West. The cost-benefit study is currently being completed by Energy + Environmental Economics (E3).

Because the integration of PacifiCorp would require approval by California lawmakers, the ISO and PacifiCorp are helping draft language that would theoretically be brought before the state legislature before the current session closes in mid-September.

Since the November 2014 initiation of the Energy Imbalance Market (EIM), a limited market that allows CAISO and PacifiCorp to balance their systems through shared resources, the two grids have jointly benefited by over $21 million, reduced the curtailment of renewables, and cut greenhouse gas emissions.
