Private providers have started returning to the fire-ravaged state, but its insurer of last resort still has huge and growing exposure.

The massive wildfires in Pacific Palisades and Altadena in Southern California may deal a devastating blow to the state’s fragile home insurance market, which is in the midst of large-scale reforms as part of an effort to lure private insurers back to the state.
In the years running up to yesterday’s, today’s, and likely tomorrow’s fires, several home insurers announced plans to stop writing new policies in California, or even leave the state entirely. The industry and many analysts blamed not just California’s famously hostile mix of dry vegetation, high winds, and scarce rains, but also a rise in construction and reinsurance costs and a regulatory system that made it difficult for insurers to raise rates or think prospectively about risk when setting rates.
In other words, it was simply easier for insurers to not renew policies than it was for them to increase rates to better adjust for risk. Some of these non-renewals occurred in the area now affected by the Eaton Fire in Altadena, though they were most prevalent in the Bay Area and the Sierra Nevada foothills.
In response, California’s insurance commissioner Ricardo Lara rolled out a set of reforms last year that tried to both expand insurance in wildfire prone areas and lure insurers back to the state. The new rules would allow insurers to use models to determine risk (not just historical data, as the law had previously been interpreted to allow) while also mandating that insurance companies operating in the state write policies in fire-prone areas as well as in those that are relatively safe. Lara then issued another rule late last year allowing insurers to use the cost of reinsurance in determining their rates, which insurers in the rest of the country are allowed to do.
Allstate, which announced in November, 2022 that it would stop writing new home insurance policies in California, said last spring that it was considering a return to the state based on the possibility of models being allowed for ratemaking. At the end of last year, partly in response to the reforms, Farmers also said that it would restart writing new policies for some lines of business in California, and that it would increase the number of new homeowners insurance policies it writes every month after instituting limits in 2023. Last week, Verisk submitted a model to project wildfire risk to the state for regulatory agency review for use in rate-setting.

Consumer advocates have warned that these rules would lead to increases in insurance rates. So has Lara’s predecessor, Dave Jones, who has been skeptical of trying to grow the private insurance market by giving it more flexibility to set rates without addressing the core issues of climate change and fire management policy.
“In the long term, we’re not going to be able to ‘rate increase’ ourselves out of this problem,” he said in an interview with the University of California, pointing to Florida’s insurance problems as an example, despite the flexibility that insurers have in setting rates there. “In the short-and mid-term for California, giving insurers proposed higher rates will get them to start writing new insurance again — although many homes in the wildland urban interface will continue to face challenges. But in the longer term, higher rates alone are likely to be overwhelmed by the higher risks and losses from climate change — just like in Florida.”
Like Florida, California has a backup for the private market, an insurer of last resort. And, like Florida, it’s been trying to make it smaller, to little avail. It may now be so large as to place the rest of the state at financial risk.
California’s FAIR Plan is a fire insurance pool that all property and casualty insurers operating in the state contribute to in proportion to how much business they have in the state; homeowners turn to FAIR when they can’t get insurance otherwise. As the state has experienced massive wildfires and insurers have pulled out, the size of the FAIR Plan has ballooned, with exposure rising to $458 billion in 2024 from $153 billion in 2020, even as it explicitly says that its “goal is attrition” (i.e. getting customers back on normal insurance plans).
“It’s a socialized cost,” Kate Gordon, the chief executive of California Forward, a policy nonprofit, and former advisor to Secretary of Energy Jennifer Granholm, told me. “We see more and more people switching to the FAIR plan. It’s getting massively oversubscribed. It’s going to hit some kind of wall at some point.”
The communities with the most wildfire exposure for the insurer include vacation areas throughout the state such as Lake Arrowhead, Truckee, and Big Bear Lake, and affluent residential communities including Berkeley and the San Francisco suburb Orinda. They also include Pacific Palisades, the fifth most wildfire-exposed market for FAIR in Southern California, with some $5.9 billion of exposure.
While the fires have yet to be substantially contained, let alone extinguished, and the damage has not yet been calculated, the still-raging fires will likely constitute a major hit to the FAIR Plan and California insurers. The number of residential FAIR policies in the Pacific Palisades zip code grew by over 80% between 2023 and 2024, and has quadrupled since 2020. The total financial exposure for residential insurance in Pacific Palisades doubled in the past year, growing to almost $3 billion. In one zipcode affected by the fire in Altadena, residential FAIR plan policies grew by over 40% since 2020, with around $950 million of total exposure.
“As the risk of more climate change-intensified wildfires increases in California, a major wildfire in one geographical area concentrated with FAIR Plan-insured properties could overwhelm the FAIR Plan’s reserves and its capacity to quickly and fully pay consumers’ claims,” Lara wrote in a bulletin in September.
Like other states with insurers of last resort, the FAIR Plan can seek cash from insurers — which could, if the losses are large enough, extract “temporary supplemental fees from their own policyholders,” according to new California insurance regulations. This would mean that Californians who were able to buy private insurance — because they don’t live in a region of the state that insurers have abandoned — could be on the hook for massive wildfire losses. While such an assessment has not occurred since 1994, Victoria Roach, the FAIR Plan’s president, warned in a hearing before the State Assembly last March that a major fire could knock out the plan’s reserves and force it to go to insurers — and their policyholders — to shell out for the difference.

Plus more of the week’s big money moves in critical minerals and electric vehicle charging.
Two of climate tech’s hottest sectors — fusion and critical minerals — dominated this week’s funding headlines. Helion led the pack with its $465 million Series G, helping to push the startup with the sector’s most aggressive commercialization timeline one step closer to putting power on the grid. The round follows last week’s news that German fusion startup Focused Energy secured a $240 million Series A, making it Europe’s most valuable fusion company.
Then there’s the critical minerals. Shortly after venture firm Gigascale Capital announced the close of its $250 million fund targeting the physical clean energy economy, it announced one of its first investments: Red Metals, a startup working to bring copper refining back to the U.S. Terra AI, which is using artificial intelligence to identify promising sites for mineral extraction, also landed fresh funding. Rounding out the week’s deals, EV charging and energy services company InCharge also raised a new round as it looks to expand into a broader suite of energy services.
Leading fusion startup Helion has nearly tripled its valuation with its latest $465 million Series G round, which aims to help the company deliver commercial fusion power this decade — the most ambitious timeline in the industry. Per the terms of the power purchase agreement Helion signed with Microsoft in 2023, the startup plans to turn on its first commercial reactor just two years from now. That’s far sooner than even its most precocious competitors, who aim to put fusion power on the grid by the 2030s at the earliest.
Joshua Kushner’s venture firm Thrive Capital led the round, which also included participation from new investors including Lux Capital and Alta Park Capital. Thrive now values the company at $15.5 billion.
“The investors that have joined this round, it’s institutional capital, some very marquee investors,” Helion’s CEO David Kirtley told me, explaining they were willing to back an unproven technology thanks to a series of recent milestones that Helion’s latest prototype reactor, Polaris, achieved. “Polaris earlier this year set records for temperature and fuel. We’ve also reduced a lot of the business risk on the regulatory front, the commercial front, and the actual supply chain, too.” In February, Polaris became the first reactor developed by a private fusion company to operate on deuterium-tritium fuel — the most common fuel in the industry — and to achieve a plasma temperature of 150 million degrees Celsius.
Helion differs from many of its peers pursuing more established reactor concepts such as tokamaks, stellarators, or laser-driven inertial confinement. Instead, Helion’s tech uses powerful magnets to collide and compress two fusion plasmas together, generating temperatures over 100 million degrees Celsius and triggering a fusion reaction. It then seeks to capture the electricity this reaction generates via electromagnetic induction — no steam turbine required — similar to the way regenerative braking works in an electric vehicle. If successful, the approach could enable smaller, more modular fusion reactors than conventional designs would.
While the company had originally aimed for Polaris to demonstrate electricity production from fusion in 2024, that date came and went with no new goal set. Kirtley told me that Helion remains on track to meet the terms of its agreement with Microsoft, however. The startup broke ground on its commercial reactor site last year in Malaga, Washington, where it already has access to a substation and grid interconnection from a dormant aluminum smelter. In addition to building out this facility, Helion also plans to use its new funding to boost production at its electrical component manufacturing plant in nearby Everett, which Kirtley said opened earlier this year.
As investors pour billions into artificial intelligence and the infrastructure supporting it, former Meta CTO Mike Schroepfer has raised an inaugural $250 million fund for his venture firm, Gigascale Capital, which is focused on the physical clean energy economy. This represents Gigascale’s first institutional fundraise since its founding in 2023; until now, the firm’s investments have come entirely out of Schroepfer’s own pocket.
The fund will target early-stage companies working in clean energy, grid infrastructure, critical minerals, and AI-enabled design and manufacturing, while reserving capital to continue backing its portfolio companies as they scale. Gigascale has already backed a number of big names in the space, including Commonwealth Fusion System, iron-air battery developer Form Energy, solid-state transformer company Heron Power, and clean baseload power startup Arbor Energy.
It’s also already begun investing out of this new fund, announcing this week that it led a $10 million seed round for critical minerals company Red Metals, which also included participation from JB Straubel, founder and CEO of the battery recycling company Redwood Materials. The company aims to help reshore copper refining in the U.S., and will use this fresh capital to support the development of a $70 million refining facility in Charleston, South Carolina. Red Metals says its process can convert copper scrap directly into a finished copper product, bypassing several of the costly and emissions-intensive intermediate steps typical of conventional refining.
The investment offers a window into the kinds of companies Schroepfer is most interested in — businesses that might lack the glamor of an AI startup but represent bipartisan opportunities to address core industrial bottlenecks. Copper, for example, is essential to all sorts of clean energy infrastructure, including transformers, power lines, and anode battery materials, but also critical for defense technologies such as radar systems and ammunition. Yet American copper production has been on the decline, with analysts projecting that the U.S. will face a refined copper shortage of over 2.5 million metric tons annually by 2035.
Sustainability-focused firm S2G Investments has been on a roll recently, announcing a $1 billion fund last month that aims to fill climate tech’s “missing middle” and backing Goshe Energy Storage with up to $40 million in strategic financing last week. Its latest move is leading a $46 million strategic investment round for InCharge Energy, an EV charging and distributed energy management company.
InCharge got its start installing and managing electric vehicle charging stations, and is now operating more than 30,000 assets across North America. Through its software platform and network of technicians, the company handles all monitoring, diagnostics, and on-the-ground repairs, taking on a charger’s full lifecycle to minimize downtime. With this new capital, InCharge plans to expand beyond EV charging and leverage its software and field service network in adjacent industries, including electrical infrastructure work such as panel upgrades and wiring repairs, as well as distributed energy resources like rooftop solar and battery storage systems.
“EV charging was the entry point, but our customers increasingly need help operating more complex energy infrastructure,” Rich Mohr, InCharge’s CEO said in a press release. “This investment from S2G accelerates our evolution into a full energy solutions provider and allows us to advance smarter technology and strengthen our service capabilities nationwide.”
It’s a hot week — nay a hot year, for critical minerals and subsurface exploration startups, especially for those pairing geology with artificial intelligence. AI-powered mineral exploration company KoBold Metals has raised about $1.2 billion to date, while geothermal exploration startup Zanskar has brought in about $220 million.
Now, another entrant is attracting investor attention. Terra AI has raised a $20 million Series A led by Khosla Ventures to help do it all — use AI to identify prospective sites for critical minerals mining, next-generation geothermal development, and permanent carbon sequestration.
Terra’s platform integrates vast geological and geophysical datasets to generate 3D subsurface models, as well as risk assessments that allow teams to evaluate a range of potential geologic scenarios. From there, the team can identify the best sites for exploratory drilling and thus reduce risk and uncertainty much sooner in the project’s lifecycle. The company even uses what it calls “geology reasoning agents” to help operators create their exploration plans, all with the goal of drastically reducing the notoriously long timeline between discovery and production, which can stretch to nearly two decades for many subsurface projects.
“Minerals sit at the center of every major technology and infrastructure transition, but today’s exploration results are not keeping pace with demand,” Terra’s CEO John Mern posted on LinkedIn. “Our mission is to advance the frontier of AI into the geosciences and help supply the metals and resources the next generation needs.”
One of the biggest fusion funding rounds of the year landed last week, and somehow much of the media — including me — missed it. German fusion startup Focused Energy raised a whopping $240 million Series A led by RWE, one of Germany’s largest energy companies. Yet unlike most deals of this magnitude, it arrived with little fanfare: No press release in my inbox nor a flood of headlines. So in the interest of making up for lost time, here are the details.
With this latest round, which also includes participation from the German Federal Agency for Breakthrough Innovation, the European Innovation Council Fund and Prime Movers Lab, Focused Energy has become Europe’s most valuable fusion company. Like several other leading players, including Inertia Enterprises and Pacific Fusion, Focused Energy relies on an approach known as inertial confinement fusion. This involves using powerful lasers to compress a tiny fuel target, creating the extreme pressures and temperatures required for a fusion reaction. To date, inertial confinement remains the only approach to have demonstrated net energy gain, with Lawrence Livermore National Lab achieving this milestone in 2022.
The startup plans to use this latest funding to build out a demonstration plant in the German state of Hesse, at a site where RWE formerly operated a nuclear fission plant. The company ultimately aims to build a commercial reactor by the mid-2030s.
Catching up with the American Council on Renewable Energy’s Ray Long.
Today’s chat is with Ray Long, CEO of the American Council on Renewable Energy. We first discussed the odds of permitting reform a year and a half ago, for one of the first Q&As in The Fight. Flash forward and we’re still in the same situation, but now also wrestling with added demand for electricity to power data centers. I wanted to talk again about whether he thought the rise of artificial intelligence would increase the odds of some federal deal happening any time soon. The result: a wide-reaching conversation about the future of the electric grid, the struggles to win community buy-in and the sclerotic nature of the U.S. Congress.
The following conversation was lightly edited for clarity.
Do you think the buildout of our energy grid is entwined with the rise of the nation’s data center buildout?
When you look at what we need over the next four years — 166 gigawatts, 15 times the peak load of New York City — that’s a lot of power to build. Roughly half of that is for data center and AI growth.
There are five things we can build in the next four years at scale to address that collective amount. First, it’s transmission — the transmission buildout will help to get a modern grid to enable power flow to where it’s needed in a much more effective way. That’s the first step because if we just build all that power, the current grid can’t handle it.
Second, there are four supply technologies that can be built: solar, batteries, wind, and natural gas. All four of those technologies, we know there’s enough equipment here in the U.S. available for purchase that we can build at volume. And I’ll say this — natural gas is only about 10% of all those gigawatts because of the availability of turbines from suppliers. You can’t get enough over the next four years. So when I talk about decarbonization, most of what is built to address this issue is zero-carbon resources, renewable energy resources.
If you were to compare the current conversation around data center development to the debate over developing renewable energy in the U.S. — or energy in general — do you see any similarities or differences?
There are always issues with permitting projects. Communities are always going to have concerns about what’s built in their backyards.
What’s new — and your polling shows this — is the level of concern communities have. But here’s the thing: Most of this can be overcome by developers going in, listening to what the needs of the communities are, then responding and through the permitting process addressing those concerns. You can’t do that 100% of the time. But my experience is, when you take that sort of approach, you can overcome a lot of it.
Most of the large data centers are actually doing the things I’m discussing — going in and saying, Look, we want to be grid interconnected because grid connection at the end of the day means the resources we’re bringing to bear are also going to make a stronger grid. Number two, it's investing in power generation sources like the ones I said — and those power sources will be on the grid, so they’ll solve for the increased power demands of a community.
Third, water. They should bring the water solutions. You’re seeing data centers coming in and saying it head on now, that they have closed-loop systems or whatever the solution is. At the end of the day, the communities they’re proposing these in have a real negotiating opportunity to make sure they’re holding the data center developers accountable to the needs of the community.
For a community to say we don’t want it here misses a real opportunity for those communities to get the power they need, the grid they need, and the ability to bring down energy costs.
How is the data center debate affecting permitting reform conversations in Washington, from your perspective?
Permitting reform in the U.S. at the state and federal level has been broken for years. The SunZia transmission project? It took 17 years to permit. Ribbon-cutting is in a week or two and there’s still litigation around it. From a business perspective, it’s just untenable, and it’s a miracle that the project is getting built. Developers need a chance to come in and have their project evaluated. Both the community and the developer should be able to get to a go or no-go in a couple of years on one of these projects.
How is data center growth affecting the permitting reform discussion? It’s a very hot issue right now. Right now I think in part because the data center issue is so huge — because we’ve only got four years to solve for the first really big tranche of power we need and prices across the board for electricity are escalating — this is coming to a head. The data center load is a part of the catalyst to get people talking about it [permitting reform].
Do you expect legislating in Congress on permitting reform this year? Anything beyond more conversation?
My hope is that we get a bill. A few weeks ago someone from the administration was quoted as saying they wanted a framework for a bill by the end of May, and it’s June now. We haven’t seen both sides or the administration coalesce around a final project yet.
We’re in a midterm election cycle. Typically it’s very difficult during these cycles to move bills like this. At the same time, with electricity prices increasing and the need to build more, to fix this, I’m very hopeful something will come together. And look at the Senate — you’ve got Republicans and the Democratic ranking members talking about this. It’s all good signs.
If everyone’s talking about energy and affordability during this election, isn’t that a good thing for action in the next Congress?
I’ll say this: You’re seeing the catalyst for it right now with prices rising, and almost every grid operator around the country has raised concerns about shortages at some point this year or next year. It’ll hopefully be enough to have policymakers do something about it this year.
Plus more of week’s biggest development fights.
1. Ohio — This state might just be the most important flashpoint in the national fight over advanced energy and tech infrastructure.
2. Laramie County, Wyoming — The Cowboy State’s capital city is one of the few to reject a data center moratorium. But tech companies. don’t get your hopes up too high.
3. Los Angeles County, California — Elsewhere, we saw the first city in California vote to ban data centers … once and for all.
4. Charles County, Maryland — This populous county south of D.C. is now out of reach for data center development.
5. Baldwin County, Alabama — There will be a vote at the end of this month on whether to ban solar in the county whose opposition nearly prompted a statewide moratorium on development.
6. Hopkins County, Texas — I have one last update related to a large data center legal fight we’ve been covering closely.
