What is BESS thermal runaway? How can it be prevented or mitigated? Please plan to attend this meeting of the Industry Applications Society to learn more. The speaker will be Rick Reynolds, Executive Vice President, ORR Protection Systems. Battery Energy Storage Systems (BESS) are being installed at an ever-increasing pace in an effort to mitigate the infamous duck curve caused by the ramping of renewable energy resources. The duck curve pattern is created by the midday dip (belly) in the net load curve, followed by a steep rise in the evenings when solar generation declines. Recently, there have been multiple reported BESS failures at utility-scale installations around the world. Just in California, in the past 3 years there have been the following incidents according to the EPRI's Battery Energy Storage System Failure Incident Database: - San Diego, CA – May 15, 2024 (250MWh/250MW, LG Chem) - Valley Center, CA – Sept 18, 2023 (560MWh/140MW, LG Energy) - Moss Landing, CA – Sept 20, 2022 (730MWh/182.5MW, Tesla) - Valley Center, CA – Apr 5, 2022 (560MWh/140MW, LG Energy) - Moss Landing, CA – Feb 13, 2022 (400MWh/100MW, LG Energy) - Moss Landing, CA – Sept 4, 2021 (1,200MWh/300MW, LG Energy) This presentation highlights the pressing need to enhance safety measures in lithium-ion battery usage. The presentation examines current risks, draws insights from past incidents, and explores best practices and fire suppression systems. Embracing future trends, it advocates for collaboration, compliance with standards, and continuous monitoring to achieve the vision of zero lithium-ion battery fire incidents. Agenda: Time: No-host social at 5:30pm; Presentation at 6:00pm; Dinner at 7:00pm. Presentation continues at 7:45pm; Adjourn by 8:30pm Place: Zio Fraedo’s, 611 Gregory Lane, Pleasant Hill.

Santa Clara Valley IEEE Power & Energy and Industry Applications Societies Co-hosted by SF PES, OEB PES Join us October 2nd for a presentation and discussion on: PG&E & Community Microgrids Speakers:  Shreya Kodnadu and Franz Stadtmueller: Grid Innovation | Clean Energy and Sustainability Advocates, PG&E Cost:  IEEE Members $15 by 9/26  Non-Members $25 by 9/26 (After 9/26, if space available, registration will be $5 more and non-refundable) Date: October 2, 2024, 6:00 to 8:30 PM Place: Delta/Marriott Hotel Santa Clara-Silicon Valley, 2151 Laurelwood Road, Santa Clara CA 95054.  Room to be posted in hotel lobby. Agenda: 6:00                Check in, Meet and Greet 6:30                Dinner buffet 7:00                Talk 8:00                Q&A 8:30                End Registration required by September 26: Register now About the talk: When severe weather or other events take the electric grid down is your community ready? If your answer is no, a community Microgrid might be the solution. A Microgrid (MG) can provide a source of localized power during a grid outage due to extreme weather, a Public Safety Power Shutoff event or other outage. In addition, they can offer efficiency, cost and environmental benefits.  A community MG is a group of PG&E customers and Distributed Energy Resources (DERs) within a clearly defined electrical boundary able to disconnect and reconnect to the grid, so critical facilities can be safely energized.   They are typically designed to provide energy resilience to important community facilities, such as: Hospitals Police and Fire Stations Gas Stations and Markets The local DERs, such as a solar photovoltaic (PV) system and battery, can be owned by third parties and can participate in wholesale markets for energy and related services.  PG&E will continue to own and operate the distribution system on which the Microgrid capability is built. PG&E’s Community Microgrid Enablement Program (CMEP) and Microgrid Incentive Program (MIP) offer both financial and technical support.  Creating a community MG requires collaboration between your community, a technical engineering firm, and PG&E.  The CMEP and MIP can help you take your community’s energy resilience ideas from concept to reality. This presentation will offer a general definition of community MGs, including architecture, electrical design, operational modes, DER’s etc., and offer an example of an implemented solution.  Also, it will describe CMEP steps: Consultation Application Study & Analysis Development Operation The CMEP and MIP work together to fund all aspects of a community Microgrid. They support the development of clean community Microgrids in disadvantaged and vulnerable communities (DVCs). You can apply for either one individually, or for both programs together. About the Speakers: Shreya Kodnadu, PG&E: Grid Innovation Engineer, Pacific Gas & Electric’s Microgrid group. In this role, she develops and implements strategies to scale community microgrid programs, ensuring their resilience and effectiveness. She holds an MS in Power System from Washington State University and has previously worked at Schweitzer Engineer Lab and other utilities on both East and West Coasts. She is currently pursuing her MBA at UC Berkeley Haas. Franz Stadtmueller, PG&E: Grid Innovation | Clean Energy and Sustainability Advocate. Franz Stadtmueller received his BS in Electrical Engineering/Power Systems & Electronics from the University of Wisconsin-Madison and works as a Principal Electrical Engineer in Pacific Gas & Electric’s Applied Technology Services Department.  Franz is a subject matter expert in the area of power system modeling and electrical testing with most recent work on PG&E’s Ground Fault Neutralizer project, grid-forming inverters, and distribution microgrid island studies.
