Preliminary report on August outages issued
The ISO, California Public Utilities Commission (CPUC), and California Energy Commission (CEC) issued a Preliminary Root Cause Analysis of the August 2020 heat wave and rotating outages, finding that resource planning targets have not evolved to keep pace with climate change-induced extreme weather events, and that energy market practices did not perform as intended during stressed conditions.
analysis, released on October 6, also outlines short-term and longer-term actions to mitigate electricity shortages and ensure delivery of clean, reliable, and affordable energy.
The Preliminary Root Cause Analysis finds that there was no single root cause for the rotating outages on August 14 and 15. Instead, there are three broad categories of factors that contributed to the outages:
- The climate change-induced extreme heat storm across the western US resulted in the demand for electricity exceeding the existing electricity planning targets. The existing resource planning processes are not designed to fully address an extreme heat storm like the one experienced in mid-August.
- In transitioning to a reliable, clean affordable resource mix, resource planning targets have not kept pace to lead to sufficient resources that can be relied upon to meet demand in the early evening hours. This makes balancing demand and supply more challenging. These challenges were amplified by the extreme heat storm.
- Some practices in the day-ahead energy market exacerbated the supply challenges under highly stressed conditions.

ISO adopts storage resource enhancements
The ISO Board of Governors approved energy storage and distributed energy resource enhancements, making it easier to integrate and operate these resources while maintaining grid reliability.
The Board’s October 2 approval of Phase 4 of the Energy Storage and Distributed Energy Resources (ESDER 4) enhancements includes:
- An optional end-of-hour, state-of-charge parameter to give storage resource owners real-time management of future resource use commitments.
- Offering demand response resource owners the option of including a daily maximum run time constraint, and requiring a minimum of 1 megawatts (MW) curtailment to better manage demand response.
- Streamlined participation by simplifying agreements for non-generator resources.
Battery and hybrid resources are fast growing components of the resource mix, with more than 1,500 MW scheduled to connect to the grid by the end of 2021, and are an important component of a reliable and clean electricity grid.

ISO welcomes new CEO Elliot Mainzer
New ISO President and CEO Elliot Mainzer was welcomed by the Board of Governors at his first meeting on October 2.
Mainzer, who had decades of leadership experience in the energy industry, served as administrator and CEO of the Bonneville Power Administration (BPA) before joining the ISO.
“I congratulate Steve on his remarkable career at the ISO and his legacy of operational excellence, market transformation and collaborative relationships,” said Mainzer. “I am committed to continuing the ISO’s work with stakeholders, partners, and regulators to decarbonize the grid while maintaining system reliability.”
During his 18-year career at BPA, Mainzer held a variety of management positions in the agency’s Power, Transmission and Corporate organizations, including trading floor manager and manager of transmission policy and strategy. As executive vice president of Corporate Strategy, he led BPA’s strategic planning process and provided policy leadership and cross-agency coordination on renewable resources, market design, climate change and integrated planning. Mainzer also led BPA’s ambitious grid modernization initiative, investing in business processes and operating systems essential for BPA’s participation in the evolving electricity market.
A native of San Francisco, Mainzer earned his bachelor’s degree in geography from the University of California, Berkeley and master’s degrees in business administration and environmental studies from Yale University.
