PacifiCorp agrees to explore full participation in California ISO

The California Independent System Operator Corp. (ISO) and PacifiCorp are pleased to announce they have signed a memorandum of understanding indicating that the Portland-based energy company will explore full participation in the ISO as a Participating Transmission Owner. The memorandum paves the way for performing a joint study on the feasibility and benefits of PacifiCorp joining the only competitive wholesale market in the West.

The ISO is an independent, non-profit organization that manages about 80 percent of the energy flow in California. PacifiCorp is one of the West’s leading utilities, serving nearly 1.8 million customers in Oregon, Washington, Utah, Idaho, Wyoming and a small portion of California. A decision to join the ISO by PacifiCorp would allow for a full coordination of the two largest electrical transmission grids in the region and allow customers served by both entities access to a broader array of power generation at lower costs.

“PacifiCorp has become a valued partner and we are pleased that they are exploring the value of fully taking advantage of the ISO’s state-of-the-art technology, planning talent and full spectrum of market products,” said ISO President and CEO Steve Berberich.

Last November, PacifiCorp began participating in the six-state Energy Imbalance Market, or EIM, which is a part of the efficient and effective services the ISO provides. In its first few months in the EIM, PacifiCorp has realized millions in cost benefits, which helped inform its decision to explore expanding that partnership to increase cost savings for customers, enhancing grid reliability and to support its clean energy goals.
