Puget Sound Energy Reports to the Washington UTC on the Progress of its Efforts to Join the CAISO Energy Imbalance Market; CAISO Releases Study Chronicling Benefits of a Regional Energy Market
By Eric Jay and Kari Vander Stoep
Puget Sound Energy (“PSE”) recently presented to the Washington Utilities and Transportation Commission (“WUTC”) regarding the steps it is taking to join the California-based Energy Imbalance Market (“EIM”) this coming fall. WUTC Docket No. 151425 (July 20, 2016). The EIM is a new energy market overseen by the California state energy balancing authority – the California Independent System Operator (“CAISO”) – that came online in November 2014. It is intended to increase reliability and other benefits for affected costumers by coordinating the dispatch of energy generation and transmission from utilities across an expanded geographic footprint that is expected to encompass significant portions of eight western states by the end 2018. As of the end of the second quarter this year, CAISO estimates that the EIM has resulted in a $65 million gross benefit for its participants to-date.
