Texas Bitcoin Mining Insurance: What Most Operators Get Wrong About ERCOT, Fire Risk, and SB 6

Texas controls roughly 28.5% of all US bitcoin mining hash rate. That’s not a minor footnote — it means more concentrated mining risk sits on a single isolated grid than anywhere else in the country. ERCOT doesn’t connect to the Eastern or Western Interconnects, which is worth understanding before you assume your business interruption policy was written with your operation in mind. It wasn’t.

In December 2025, a fire at NFN8 Group’s 78,000-square-foot Crystal City facility cut their capacity in half. They had insurance. On February 2, 2026, they filed Chapter 11 anyway — because in their own bankruptcy filing, the “timing of payment remains uncertain.” They needed $2.75 million in DIP financing just to stay alive while the claim adjusted. That’s the gap between having coverage and having a policy that actually works.

Why Texas Mining Insurance Is Categorically Different From Every Other State

Location isn’t a footnote here. In Texas, it’s the whole analysis.

Most insurance content treats mining risk as a general category — equipment, fire, theft, maybe some business interruption. What gets missed is the specific convergence of factors that makes a Texas mining facility a completely different underwriting problem than the same facility would be in Georgia or Wyoming.

Start with the grid. ERCOT operates as an island. When a winter storm hits Texas, miners can’t import power from neighboring regions — prolonged downtime after weather events is structurally more likely here than anywhere else. That’s not an opinion; it’s how the grid is built. Then layer in the deregulated electricity market, which lets miners earn curtailment revenue by selling contracted power back during peak demand. Valuable operationally. But that income stream creates a business interruption calculation problem that no standard policy language currently addresses.

And then there’s the weather. The ERCOT grid manages roughly 90,000 miles of transmission lines, and the facilities sitting on it face named windstorm exposure on the Gulf Coast, freeze risk across the Permian Basin, severe hail in West Texas, and summer temperatures that routinely push past 115°F. Standard commercial property policies were not written for this combination. The exclusions that matter most in Texas claims are usually the ones nobody read until after the loss.

Senate Bill 6 (June 2025): The New Compliance Exposure Most Operators Haven’t Priced In

Texas SB 6, signed June 20, 2025, is the biggest change to mining insurance exposure in the state’s history. Energy law firm Baker Botts describes it as establishing mandatory curtailment readiness requirements for all large loads. Here’s what that means in practice for insurance programs.

Facilities at or above 75 MW must install remote-controlled disconnection capability by December 31, 2025. Missing that deadline creates regulatory liability exposure. The issue is that standard commercial general liability policies often exclude “intentional acts” and “known violations” — non-compliance with a hard regulatory deadline could fall into that language depending on how an adjuster reads it. This is a gap worth closing before it becomes relevant.

Beyond the disconnect requirement, ERCOT now has authority to direct curtailment before and during grid emergencies. Operators who cannot comply face penalties — and if a failure to curtail during an emergency contributes to third-party harm, the liability exposure from that event could exceed the property loss from the same incident. The Public Utility Commission of Texas enforces SB 1929 registration for facilities at this scale, with penalties up to $25,000 per day for non-compliance. That’s an uninsured regulatory fine risk that lives entirely outside standard policy coverage.

For publicly traded miners — Riot, Marathon, Cipher, CleanSpark, Iris Energy — SB 6 compliance status is now a material disclosure item. Directors and officers coverage needs to account for securities litigation exposure tied to how compliance is communicated to investors.

The Seven Coverage Types Texas Mining Operations Actually Need

We’ve reviewed mining insurance programs from operations ranging from 5 MW single-site facilities to 500+ MW multi-campus operations across Texas. The coverage gaps we find aren’t exotic. They’re predictable errors that come from applying standard commercial insurance thinking to a risk that isn’t standard.

1. Commercial Property — The ASIC Valuation Problem

ASIC miners are unlike any other category of commercial equipment because their replacement cost moves directly with bitcoin’s price. At $60,000 BTC, the global ASIC equipment market was worth $15–20 billion. At $25,000 BTC, that same hardware was worth $8–10 billion — a 40–50% compression with no physical change to the equipment. Milliman’s actuarial work quantifies exactly this dynamic.

Three valuation methods exist. Replacement Cost Value covers the cost to replace damaged equipment with new equivalent hardware — preferred by lenders, creates overinsurance risk during BTC price declines. Actual Cash Value deducts depreciation, which leaves operators exposed to the gap between book value and actual replacement cost, a gap that widens when next-generation ASICs cost 30–40% more than the units they replace. Agreed Value eliminates coinsurance penalties by pre-agreeing on valuation — the most sophisticated choice for operators who actively manage their program, but it requires annual updates as markets shift.

The coinsurance margin clause is what punishes undervaluation at claim time. Most specialty mining policies use 110% margin clauses — if you’re within 10% of actual value, no penalty. If you’re 20% underinsured, a $2M claim becomes a $1.6M settlement. We’ve seen this play out in post-fire claims where operators hadn’t updated their statement of values after BTC appreciated 40% mid-policy.

2. Business Interruption — The ERCOT Curtailment Revenue Gap

This is the coverage dispute that’s going to define mining insurance litigation for the next five years. And most operators don’t know it exists.

The core problem: standard BI policy language has no provision for “other income earned from the same capacity during the loss period.” It was written for manufacturers who don’t earn money by shutting down production. Riot earned $30.6 million from curtailment credits in Q3 2025 alone — revenue generated specifically by not mining. If a fire takes out half their Rockdale facility, their BI claim covers lost mining revenue. But if ERCOT scheduled that same capacity for curtailment during the same period, adjusters are now asking whether curtailment income offsets the BI recovery.

The right fix is a manuscript endorsement negotiated before the loss, stating explicitly that ERCOT curtailment revenue is not considered “other earnings” for BI offset purposes. This is negotiable with specialty markets. It is not available after a claim is filed. If you earn material curtailment revenue and your current policy has no language addressing this, that’s a gap worth fixing at renewal.

For BI calculation methodology, most specialty markets have settled on hash rate capacity multiplied by a pre-agreed BTC price — typically a trailing 90-day average — rather than projected future prices. Relm Insurance went further with the industry’s first bitcoin-denominated BI policy, settling claims in BTC rather than USD and eliminating currency conversion disputes entirely.

3. Equipment Breakdown vs. Property — The Power Surge Dispute

A power surge originating outside your facility that damages your ASICs is a property claim. A surge originating inside your facility’s electrical infrastructure is an equipment breakdown claim. In practice, determining origin is contested in almost every surge-related claim.

Why this matters in Texas specifically: ERCOT grid events create both types simultaneously. During a rapid reconnection after curtailment, voltage fluctuations can affect your facility’s internal electrical systems and the ASICs themselves at the same time. Gen Re’s property underwriting analysis notes that mining facilities running at 100% electrical load 24/7 generate equipment breakdown losses at rates substantially higher than traditional data centers operating at 60–70% capacity. The cleanest solution is carrying both coverages with the same carrier — or with explicit coordination language between carriers — so the dispute doesn’t happen at claim time.

4. Workers’ Comp in the Only Opt-Out State

Texas is the only state where private employers can legally decline workers’ compensation. The Texas Department of Insurance estimates 22–44% of employers operate as non-subscribers. The financial case for opting out is real — ERISA-qualified occupational accident plans typically run 15–40% cheaper than equivalent workers’ comp premiums.

But mining facilities have above-average injury exposure by every relevant metric: 480V electrical systems, ambient temperatures exceeding 110°F in West Texas summers, heavy mechanical equipment for container installation and ASIC rack construction, remote locations that extend emergency response times, and industrial cooling systems creating sustained noise exposure. Non-subscribing employers in Texas lose four critical legal defenses if an employee is injured: the exclusive remedy limitation, contributory negligence, assumption of risk, and co-employee immunity. A serious electrical injury or heat stroke fatality at a remote West Texas facility, without those defenses, means unlimited damages exposure including pain and suffering and punitive damages. The premium savings need to be weighed against that specific math, not just the average math.

5. Inland Marine for Container Operations

A significant portion of Texas mining capacity runs in shipping containers. Standard commercial property policies cover equipment at a scheduled location — not equipment in transit, at temporary locations, or at unscheduled sites. Container-based operations that move seasonally to follow favorable ERCOT power prices need inland marine coverage that follows the equipment, not the address.

6. Cyber Liability

The real cyber exposure for mining operations isn’t someone stealing bitcoin. It’s ransomware encrypting control systems and taking a facility offline, social engineering attacks targeting banking credentials, and — as facilities pivot toward AI/HPC workloads — data breach exposure from customer workloads that didn’t exist in pure mining operations. Operators who classify themselves as “hardware businesses without customer data” may be misjudging their actual exposure as those workloads change.

7. D&O, GL, Environmental, and Builder’s Risk

General liability should extend to visitor and contractor injuries at facility sites, third-party property damage from electrical events, and noise and vibration complaints from neighboring properties — a real issue Marathon faced at their Granbury location. Environmental liability covers chemical coolant spills from immersion cooling systems. Builder’s risk covers new facility construction, a $20M–$50M+ exposure during buildout that most operators don’t think about until a weather event hits a half-finished facility.

What Texas Mining Insurance Actually Costs in 2026

The structural reason mining premiums run 5–10× higher than traditional data centers is simple: data centers operate at 60–70% of rated server capacity. Mining facilities run ASICs at 100% continuously. Data centers maintain controlled environments at 65–75°F with enterprise UPS and generator backup. Mining facilities, especially container-based West Texas operations, run at ambient temperatures that stress every component and frequently lack automatic fire suppression. The power density per square foot is 3–5× higher. Insurers price that difference.

These ranges assume competent risk management — COPE documentation, fire suppression where applicable, 24/7 monitoring — and will be wider for facilities that lack these controls.

• $1M TIV (small independent, 1–2 containers): $20,000–$50,000 annually. Access is limited — many specialty carriers require $3M+ minimum TIV. Expect Lloyd’s markets through specialist brokers.
• $5M TIV (mid-scale, 5–15 MW): $75,000–$175,000 annually. Multiple carrier options emerge at this scale. Fire suppression certification can reduce premiums 15–25%.
• $10M TIV (20–50 MW): $150,000–$400,000 annually for a comprehensive program. Gulf Coast facilities add 20–35% for named windstorm buy-down coverage.
• $25M TIV (50–150 MW): $350,000–$900,000 annually. Program structure matters at this scale — single-carrier versus layered towers affects both pricing and claims management efficiency.
• $50M+ TIV (150+ MW): $500,000–$2.5M+. These programs require manuscript policies, custom BI language addressing ERCOT curtailment economics, and annual stewardship reviews.

Which Carriers Actually Write Texas Mining Insurance

Standard carriers don’t. Hartford, Travelers, and Chubb’s retail markets generally won’t write standalone bitcoin mining property programs. The markets that do are concentrated in the Lloyd’s of London ecosystem and a handful of specialized MGAs.

Evertas is the most established dedicated crypto insurance company, operating as a Lloyd’s coverholder with capacity up to $360 million for a single risk. They write property, BI, crime, and D&O for institutional operations. Expect 30–60 days to place a new account.

AnchorWatch, backed by Arch Insurance, focuses on mining property. Their policy terms explicitly address common coverage disputes — lightning-caused fires are covered, while power surges of unidentified origin are often excluded. That distinction matters enormously in post-storm claims in West Texas.

Relm Insurance, Bermuda-based, wrote the industry’s first bitcoin-denominated BI policy. Strong on ASIC valuation methodology and coinsurance margin clause negotiation.

For smaller operations that don’t meet specialty carrier minimums, excess and surplus lines markets through brokers with non-admitted carrier access can provide coverage — typically at higher rates and with broader exclusions than purpose-built mining policies. Access to any of these markets requires a broker with active specialty relationships. A standard commercial lines broker won’t have it.
