Battery Developers Are Feeling Bullish on Mamdani

NineDot Energy’s nine-fiigure bet on New York City is a huge sign from the marketplace.

Battery storage is moving full steam ahead in the Big Apple under new Mayor Zohran Mamdani.

NineDot Energy, the city’s largest battery storage developer, just raised more than $430 million in debt financing for 28 projects across the metro area, bringing the company’s overall project pipeline to more than 60 battery storage facilities across every borough except Manhattan. It’s a huge sign from the marketplace that investors remain confident the flashpoints in recent years over individual battery projects in New York City may fail to halt development overall. In an interview with me on Tuesday, NineDot CEO David Arfin said as much. “The last administration, the Adams administration, was very supportive of the transition to clean energy. We expect the Mamdani administration to be similar.”

It’s a big deal given that a year ago, the Moss Landing battery fire in California sparked a wave of fresh battery restrictions at the local level. We’ve been able to track at least seven battery storage fights in the boroughs so far, but we wouldn’t be surprised if the number was even higher. In other words, risk remains evident all over the place.

Asked where the fears over battery storage are heading, Arfin said it's “really hard to tell.”

“As we create more facts on the ground and have more operating batteries in New York, people will gain confidence or have less fear over how these systems operate and the positive nature of them,” he told me. “Infrastructure projects will introduce concern and reasonably so – people should know what’s going on there, what has been done to protect public safety. We share that concern. So I think the future is very bright for being able to build the cleaner infrastructure of the future, but it's not a straightforward path.”

In terms of new policy threats for development, local lawmakers are trying to create new setback requirements and bond rules. Sam Pirozzolo, a Staten Island area assemblyman, has been one of the local politicians most vocally opposed to battery storage without new regulations in place, citing how close projects can be to residences, because it's all happening in a city.

“If I was the CEO of NineDot I would probably be doing the same thing they’re doing now, and that is making sure my company is profitable,” Pirozzolo told me, explaining that in private conversations with the company, he’s made it clear his stance is that Staten Islanders “take the liability and no profit – you’re going to give money to the city of New York but not Staten Island.”

But onlookers also view the NineDot debt financing as a vote of confidence and believe the Mamdani administration may be better able to tackle the various little bouts of hysterics happening today over battery storage. Former mayor Eric Adams did have the City of Yes policy, which allowed for streamlined permitting. However, he didn’t use his pulpit to assuage battery fears. The hope is that the new mayor will use his ample charisma to deftly dispatch these flares.

“I’d be shocked if the administration wasn’t supportive,” said Jonathan Cohen, policy director for NY SEIA, stating Mamdani “has proven to be one of the most effective messengers in New York City politics in a long time and I think his success shows that for at least the majority of folks who turned out in the election, he is a trusted voice. It is an exercise that he has the tools to make this argument.”

City Hall couldn’t be reached for comment on this story. But it’s worth noting the likeliest pathway to any fresh action will come from the city council, then upwards. Hearings on potential legislation around battery storage siting only began late last year. In those hearings, it appears policymakers are erring on the side of safety instead of blanket restrictions.

A Big Battery Relief in New York

And more of the week’s top news around project fights.

The United States.

1. Suffolk County, New York – Rarely do I get to say battery fire fears can be quelched but we have a very good example brewing in the Empire State.

  • On September 11, New York state regulators did a Friday News Dump: The Department of Environmental Conservation confirmed a large PFAS pollution site in East Hampton was explicitly tied to fighting a battery storage site fire. The investigation began after PFAS chemicals, known as “forever chemicals,” were detected in drinking water wells.
  • Investigators will still have to produce a final report, but in their bulletin confirming the pollution source, the agency said it is now working with state energy and fire officials to avoid a specific chemical fire suppression system identified as a potential culprit known as Novec 1230. “The investigation points to the fire suppression system, not battery storage, as a [PFAS] source,” the bulletin states, adding this system wasn’t used in other recent fires at BESS facilities.This defuses what was poised to be a new PR problem for the battery storage sector in a state where local moratoria and restrictive ordinances have become increasingly common.

2. Loudon County, Virginia – I can’t believe it: Data Center Alley is going to enact a moratorium.

The Case for a Data Center Dividend

A conversation with Sam Lyman of the Bitcoin Policy Institute.

This week’s conversation is with Sam Lyman, head of research at the Bitcoin Policy Institute. Originally focused on cryptocurrency, Lyman’s organization has expanded to policy and messaging development around data centers, most notably providing research many AI boosters cite to claim foreign influence is driving opposition to new hyperscale projects. Last week, the think tank released a new report calling for a novel solution to the data center permitting bottleneck: direct cash payments from data center projects to individuals involved with building them, as well as residents nearby facilities once they’re operating.

I reached out to BPI and asked for a chat with Lyman about the data center dividend proposal. I also tried to get to the bottom of where this increasingly relevant think tank stands on the general idea of a national data center law. The conversation was immensely informative. So here it is, in a lightly abridged and edited format.

Trump Keeps Wind Farms Waiting Despite Court Ruling

The administration told a federal court that it has a “new analytical methodology,” hence the continued delays.

A federal judge ruled in early August that the Trump administration’s freeze on vertical height clearances for wind turbines was likely illegal. More than a month later nearly all of the wind energy projects remain on pause, as federal officials add new red tape that industry representatives say runs afoul of the court’s edict.

Let’s catch-up quickly on the American wind sector’s existential dilemma: the federal government has control over airspace higher than 200 feet from the ground and wind farm turbines essentially always enter that sphere of control. For at least a year and a half, the Trump administration through the Department of Defense and the Federal Aviation Administration has slowly gummed up what industry and former government officials have said was once a rote, benign bureaucratic process for ensuring turbine rotation didn’t interfere with flight patterns or radar at nearby airports.
