NEW YORK \u2014 More and more, big arrays of lithium-ion batteries are being hooked up to electrical grids around the U.S. to store power that can be discharged in times of high demand.<\/p>\n
But as more energy storage is added, residents in some places are pushing back due to fears that the systems will go up in flames, as a massive facility in California did earlier this year.<\/p>\n
Proponents maintain that state-of-the-art battery energy storage systems are safe, but more localities are enacting moratoriums.<\/p>\n
\u201cWe\u2019re not guinea pigs for anybody\u2026we are not going to experiment, we\u2019re not going to take risk,\u201d said Michael McGinty, the mayor of Island Park, New York, which passed a moratorium in July after a storage system was proposed near the village line.<\/p>\n
At least a few dozen localities around the United States have moved to temporarily block development of big battery systems in recent years.<\/p>\n
Long Island, where the power grid could get a boost in the next few years as offshore wind farms come online, has been a hotbed of activism, even drawing attention recently from the Trump administration. Opponents there got a boost in August when Environmental Protection Agency Administrator Lee Zeldin visited New York to complain that the state was rushing approvals of sites in order to meet \u201cdelusional\u201d green power goals \u2014 a claim state officials deny.<\/p>\n

Battery energy storage systems that suck up cheap power during periods of low demand, then discharge it at a profit during periods of high demand, are considered critical with the rise of intermittent energy sources such as wind and solar.<\/p>\n
Known by the acronym BESS, the systems can make grids more reliable and have been credited with reducing blackouts. A large battery system might consist of rows of shipping containers in a fenced lot, with the containers holding hundreds of thousands of cells.<\/p>\n
China and the United States lead the world in rapidly adding battery storage energy systems. However, Saudi Arabia, South Africa, Australia, Netherlands, Chile, Canada and the U.K. have commissioned or started construction on large projects since 2024, too, according to research from BloombergNEF.<\/p>\n
In the U.S., California and Texas have been leaders in battery storage. But other states are moving quickly, often with privately developed systems. While the Trump administration has been unsupportive or even hostile to renewable energy, key tax credits for energy storage projects were maintained in the recently approved federal budget for qualified projects that begin construction in the next eight years.<\/p>\n
Developers added 4,908 megawatts of battery storage capacity in the second quarter of 2025, with Arizona, California and Texas accounting for about three-quarters of that new capacity, according to a report from American Clean Power Association, an industry group. That\u2019s enough to power nearly 1.7 million households.<\/p>\n
New York has an ambitious goal to add 6,000 megawatts of energy storage by 2030, half of it large-scale systems.<\/p>\n
\u00a0<\/p>\n
Opposition to the storage systems usually focuses on the possibility of thermal runaway, a chain reaction of uncontrolled heating that can lead to fire or an explosion. Opponents point to past fires and ask: What if that happens in my neighborhood?<\/p>\n
A battery storage system\u00a0 in Moss Landing, California caught fire in January, sending plumes of toxic smoke into the atmosphere and forcing the evacuation of about 1,500 people.<\/p>\n
Experts in the field say battery systems have become safer over the years. Ofodike Ezekoye, a combustion expert and professor of mechanical engineering at The University of Texas at Austin, notes that failures are relatively infrequent, but also that no engineered system is 100% foolproof.<\/p>\n
\u201cThis is a relatively immature technology that is maturing quickly, so I think that there are a lot of really thoughtful researchers and other stakeholders who are trying to improve the overall safety of these systems,\u201d Ezekoye said.<\/p>\n
Battery storage proponents say a facility like Moss Landing, where batteries were stored indoors, would not be allowed in New York, which has adopted fire codes that require modular enclosure design with required minimum spacing to keep fires from spreading.<\/p>\n
\u00a0<\/p>\n
People who live near proposed sites are not always assured.<\/p>\n
In Washington state, the city of Maple Valley approved a six-month moratorium in July as a way \u201cto protect us until we know more,\u201d said city manager Laura Philpot.<\/p>\n
Voters in Halstead, Kansas, which has a moratorium, will be asked this Election Day whether they want to prohibit larger battery storage systems inside the city limits, according to Mayor Dennis Travis. He hopes the city can one day host a safely designed storage system, and said local opponents wrongly fixate on the California fire.<\/p>\n
The number of localities passing moratoriums began rising in 2023 and 2024, mirroring trends in battery storage deployment, with a notable cluster in New York, according to a presentation last year by the Pacific Northwest National Laboratory.<\/p>\n
Winnie Sokolowski is among area residents against a proposed 250-megawatt lithium-ion storage system in the Town of Ulster, New York, contending it is too close to schools and homes.<\/p>\n
\u201cThey\u2019re banking on nothing happening, but I don\u2019t think you can place it where they\u2019re proposing and assume nothing\u2019s going to happen,\u201d Sokolowski said. \u201cIt\u2019s just too risky if it does.\u201d<\/p>\n
The developer, Terra-Gen, said the design will keep a fire from spreading and that the system \u201cposes no credible, scientific-based threat to neighbors, the public or the environment.\u201d<\/p>\n
New York State Energy Research and Development Authority President Doreen Harris said she\u2019s confident the state has the right safety rules in place, and that scaling up the use of battery storage systems will \u201cstrengthen and modernize our grid.\u201d<\/p>\n
She noted there also were local concerns in the early stages of siting solar farms, which have since proven their benefits.<\/p>\n<\/p><\/div>\n
