Western EIM Benefits Reach Nearly $740 Million Since Launch

CAISO’s Western Energy Imbalance Market has released its second quarter 2019 report.  The report shows the market generated $86 million in gross benefits.  This brings the total benefits produced to $736.26 million since it started in 2014.

According to the CAISO press release, “The Western EIM uses advanced technologies to automatically find and deliver the lowest cost energy to consumers across eight western states. By optimizing resources from a larger and more diverse pool, the Western EIM better facilitates the integration of renewable energy that may otherwise be curtailed at certain times of the day, providing an added environmental benefit.”

Future participants entering the Western EIM are:

  • 2020: Arizona’s Salt River Project, Seattle City Light

  • 2021: Los Angeles Department of Water and Power, NorthWestern Energy, Turlock Irrigation District, Public Service Company of New Mexico

  • 2022: Tucson Electric, Avista (serving parts of Washington, Oregon, and Idaho)

Adapt2 is tracking all of the market changes associated with the EIM impacts, and expanding its solution to help scheduling coordinators and balancing authorities to handle the changes in their processes. With the consistent addition of EIM engagement, Adapt2 recommends for CAISO participants to routinely monitor their systems for regulatory changes and how business operations are trending with an ever changing fuel mix.
