Governor makes appointments to the ISO Board of Governors


The California Independent System Operator (ISO) announced the reappointment of one of its Board of Governors members, Mary Leslie, and the appointment of a new member, Jan Schori, to round out a complete roster of five members moving into 2021.

Governor Gavin Newsom earlier this week reappointed Leslie to a three-year term on the board, and appointed Schori to fill a vacancy created by the retirement of Dave Olsen in November. Schori will serve the remainder of Olsen’s term, which ends in December 2021. The appointments are subject to state Senate confirmation.

Schori has longtime executive leadership experience in the electric industry, particularly in the areas of public policy, and operations and markets. She began her career at the Sacramento Municipal Utility District (SMUD) in 1979, and served as its General Counsel before being promoted to its general manager and chief executive officer for 14 years.

Final Root Cause Analysis published on August 2020 outages


The ISO, California Public Utilities Commission (CPUC), and California Energy Commission (CEC) issued a Final Root Cause Analysis of the August 2020 heat wave and rotating outages.

The ISO, CPUC and CEC produced a preliminary report on October 6, 2020, and have since continued their analysis to confirm and supplement their preliminary findings that the three major factors leading to the August outages were related to extreme weather conditions, resource adequacy and planning processes, and some market practices.

The reports also outline recommendations for improving grid reliability during extreme heat events. Since the August heatwave, the ISO, CPUC and CEC have taken various actions and continue focused efforts to prepare California for extreme heat waves next summer without having to resort to rotating outages.

El Paso Electric set to join Western EIM in 2023


The ISO signed an implementation agreement with El Paso Electric (EPE) to join the Western Energy Imbalance Market (EIM) in 2023, extending the real-time market to 12 western states.

EPE, a regional electric utility, provides generation, transmission and distribution service to 441,200 retail and wholesale customers in a 10,000-square mile area of the Rio Grande valley in west Texas and southern New Mexico.

Since its launch in 2014, the Western EIM has provided more than $1.18 billion in economic and environmental benefits. Using state-of-the-art technology to find and deliver low-cost energy to meet real-time demand, the Western EIM has the potential to offer additional value through the extension of the day-ahead market to participants.

The Western EIM is slated to expand this spring with the addition of Los Angeles Department of Water and Power, NorthWestern Energy, Turlock Irrigation District, Public Service Company of New Mexico, and the Balancing Authority of Northern California (BANC) Phase 2.

Western EIM fourth-quarter benefits hit nearly $69 million


The Western Energy Imbalance Market’s (EIM) 2020 fourth-quarter benefits results pushed the real-time energy market’s cumulative benefits to $1.18 billion.

Operated by the ISO, the EIM’s 2020 fourth-quarter gross economic benefits generated benefits of $68.86 million.

During the previous quarter, the regional collaboration of the Western EIM participants to transfer energy across the West to serve demand led to a 39,956 megawatt hour (MWh) reduction in curtailments. Since 2014, the EIM participants have used 1.3 gigawatt hours (GWh) of renewable energy that would have otherwise been curtailed.
