The California Independent System Operator Corporation (CAL-ISO) and NV Energy received direction from the Federal Energy Regulatory Commission (Docket No. ER15-861-004) on November 19 that allows the Nevada-based utility to move forward with participating in the western Energy Imbalance Market (EIM).


NV Energy – which serves about 1.3 million customers in the Silver State – will be the second utility to participate in the EIM, following PacifiCorp’s official entry on November 1, 2014. Puget Sound Energy of Washington State and Arizona Public Service remain on-schedule to enter the EIM in October 2016.


The western EIM – a real-time market that went live on November 1, 2014 – creates significant reliability and renewable integration benefits for ratepayers, by sharing and economically dispatching a broad array of resources. ISO advanced market systems automatically balance supply and demand for electricity every 15 minutes, dispatching the lowest-cost resources every five minutes.

CAL-ISO and NV Energy have begun implementing the final steps needed to begin full and financially binding participation in the real-time market as of December 1.
