\u201cThe Monterey County Board of Supervisors held an emergency meeting Friday morning to discuss the fire. County Supervisor Glenn Church told KSVW-TV<\/a>, \u2018There\u2019s no way to sugarcoat it. This is a disaster, is what it is\u2019.\u201d<\/p>\n<\/blockquote>\n\n\n\n

The world\u2019s second largest lithium-ion battery storage facility broke into flames last week (Jan. 16) some 77 miles south of San Francisco at Vistra Corp\u2019s Moss Landing gas-fired power plant site, prompting an evacuation order of site workers and some nearby areas. The fire initially began to subside but flared up again the next day.<\/p>\n\n\n\n

Firefighters decided to let the fire burn itself out rather than trying to extinguish it. A Monterey official told Reuters<\/a>, that \u201cthe best approach, according to fire staff, is to allow the building and batteries to burn.\u201d Officials said the fire finally burned out on January 20<\/a>.<\/p>\n\n\n\n

CNBC reported on Friday that about 40% of the building has been consumed in the fire, whose cause remains under investigation.<\/p>\n\n\n\n

The Vistra plant has 750-MW of power storage capacity, or 3,000-MWh of electric delivery, providing backup power to solar-heavy Oakland-based Pacific Gas and Electric.<\/p>\n\n\n\n

When Texas-based Vistra completed the construction of the project in August 2023, it claimed<\/a> Moss Landing battery storage was \u201cthe largest of its kind in the world.\u201d Since then, it has been eclipsed by the Edwards & Sanborn Solar + Energy Storage site in Kern County, Calif., a joint Air Force and local utilities project at 875-MW and 3,287-MWh.<\/p>\n\n\n\n

The Monterey County Board of Supervisors held an emergency meeting Friday morning to discuss the fire. County Supervisor Glenn Church told KSVW-TV<\/a>, \u201cThere\u2019s no way to sugarcoat it. This is a disaster, is what it is.\u201d<\/p>\n\n\n\n

The fire has also generated broader political interest. California Assemblywoman Dawn Addis (D-Morro Bay) issued a statement as the news of the fire spread. \u201cI am deeply concerned and have serious questions about the safety of this battery energy storage plant. I will be looking for transparency and accountability for why this happened again at Moss Landing. I am exploring all options for preventing future battery energy storage fires from ever occurring again on the Central Coast,\u201d she said. She is chair of the California Legislative Central Coast Caucus.<\/p>\n\n\n\n

Prior Problems<\/strong><\/p>\n\n\n\n

Renewable Energy World reported<\/a> that the Moss Landing battery array has a checkered history, noting that the fire broke out in the earliest, 300-MW, section of the plant. In September 2021 a software problem<\/p>\n\n\n\n

caused a heat suppression system to activate and douse three 100 MW racks of batteries\u2026,Fire crews were called, but Vistra ultimately determined there was no fire, nor did the incident cause any harm to outside systems or any personnel.<\/p>\n<\/blockquote>\n\n\n\n

In February 2022, in the 100-MW Phase II building next door, a \u201csecond<\/a>, nearly identical incident involving the early detection safety system occurred\u2026\u201d<\/p>\n\n\n\n

California\u2019s Big Bet<\/strong><\/p>\n\n\n\n

California is leading the nation in battery energy storage. No current figures are available, as the sector is growing so fast it is difficult to keep up. At the end of November 2023, according to the Energy Information Administration,<\/a> California had 7.302 GW of battery storage, followed by Texas at 3.167 GW. No other state had 1 GW of battery storage. BloombergNEF reported<\/a> that California saw 8,171-MW of storage from 2021 through 2023.  <\/p>\n\n\n\n

That makes California a test bed for battery storage, including increasing information about fires. Lithium-ion batteries are well-known for catching on fire and utility-scale fires get a lot of attention. Bloomberg reported last week<\/a>,<\/p>\n\n\n\n

After several fires at large battery installations\u2014including a 2022 blaze that briefly shut down California\u2019s Highway 1<\/a>\u2014developers switched battery formulas so that cells are less prone to overheating.<\/p>\n<\/blockquote>\n\n\n\n

A Prior Fire<\/strong><\/p>\n\n\n\n

Last May, a fire broke out<\/a> at L.S. Power\u2019s 250-MW Gateway Li-ion project near San Diego. The fire prompted evacuations and road closures in the vicinity of the plant not far from the Mexican border. The fire burned for 11 days.<\/p>\n\n\n\n

The Palo Alto-based Electric Power Research Institute (EPRI) tracks grid-scale battery energy storage systems worldwide. In a 2023 paper<\/a>, EPRI said, \u201cOver the last 4 years, there have been on average 10 such failure events annually, even as global battery deployments have increased 20-fold.\u201d [1]<\/strong><\/p>\n\n\n\n
