Energy imbalance market benefits in the west: A case study of Pacificorp and CAISO

An energy imbalance market between PacifiCorp and the California Independent System Operator (CAISO) would bring benefits of $21 million to $129 million for the year 2017, an analysis suggests. Preliminary cost estimates of setting up the EIM range from $3 million to $6 million, with an estimated annual cost of $2 million to $5 million. This suggests that a two-party EIM provides a low-cost, low-risk means of achieving operational savings and enabling greater penetration of variable energy resources. Copyright © 2013 Elsevier Inc.
