Joint Report on Energy Imbalance Market Benefits
The joint report on Energy Imbalance Market (EIM) benefits from a co-optimized ISO and PacifiCorp real-time market demonstrates a range of benefits. The benefit analysis will be presented to the ISO Board of Governors March 20, 2013 when it considers authorizing the ISO to negotiate a formal agreement with PacifiCorp.
The joint report on Energy Imbalance Market (EIM) benefits from a co-optimized ISO and PacifiCorp real-time market demonstrates a range of benefits at http://www.caiso.com/Documents/PacifiCorp-ISOEnergyImbalanceMarketBenefits.pdf. The benefit analysis will be presented to the ISO Board of Governors March 20, 2013 when it considers authorizing the ISO to negotiate a formal agreement with PacifiCorp.
The report estimates the combined benefits of the EIM will range from $21 million - $129 million in 2017. The report supports the conclusion that the two-party EIM provides a low-cost, low-risk means of achieving operational savings for both PacifiCorp and ISO and enabling greater penetration of renewable energy resources. Savings calculated with these scenarios could be higher if other entities in the West also participate in the EIM, which would expand the transfer capability within the western transmission network as well as increase available resources in the new real-time market.
While not included in the report's analysis, enhanced grid reliability and renewable integration are additional benefits that come from an EIM. These types of benefits were recently outlined in the FERC staff paper "Qualitative Assessment of Potential Reliability Benefits for a Western Energy Imbalance Market".
