Insuring Modular Data Centers and Containerized GPUs

An owned modular data center needs more insurance than servers in a colocation cage, because the operator also owns the container, the switchgear, the cooling units and the generators.

Lenders check six covers: property on the GPUs and site gear, transit and construction, equipment breakdown, lost income when outside power fails, liability, and pollution from stored fuel.

What changes when you own the site

In colocation, the facility insures its building and infrastructure, and the tenant insures the equipment in its cage. On a modular site the operator owns both layers, so every row below lands on one balance sheet.

A UPS (uninterruptible power supply) carries the load until generators start. A coolant distribution unit pumps liquid coolant between the racks and the heat-rejection plant, and a failed one stops cooling for every rack it serves.

The policies a modular site needs

Each exposure maps to a different line of insurance, and some come from different insurers.

A colocation tenant buys property, transit and general liability. The other five lines come with owning the site.

Property on the GPUs and the site gear

The GPUs carry most of the insured value. A MW of B300 servers and networking costs several times the modules around it, as modular data center cost per MW shows.

Property insurance on GPU servers is usually written on EDP (electronic data processing) or inland marine forms. Inland marine is the class of insurance built for property that moves or has no fixed location. ^{[1]IRMI, insurance definitions: "inland marine coverage" (accessed October 2026)https://www.irmi.com/term/insurance-definitions/inland-marine-coverage} Replacement cost, the equipment schedule and catastrophe pricing work as they do for any GPU cluster. A modular site changes two things:

• Schedule: every container, transformer, switchgear lineup, coolant distribution unit and generator needs its own line with a value, as each server does. Gear left off the schedule is uninsured.
• Location: the insured location is a pad, usually outdoors. The insurer asks for the site's COPE details (construction, occupancy, protection, exposure), which a colocation tenant gets from the facility.

Delivery and construction

A modular site spends months as cargo and as a construction site before it is a data center. DXN says its modules deploy about five to eight months after the contract is signed. ^{[2]IT Brief Australia, "DXN wins AUD $12.2 million AI data centre contract" (August 26, 2026)https://itbrief.com.au/story/dxn-wins-aud-12-2-million-ai-data-centre-contract}

1. Factory to pad. Modules and servers ship separately, from different suppliers. Transit cover follows each shipment, and the shipping terms decide when the buyer takes the risk.
2. Construction. A builder's risk policy covers property in the course of construction. Most are written on inland marine forms, on an all-risk basis, and also cover property in off-site storage and in transit. The limit is the project's estimated completed value. ^{[3]IRMI, insurance definitions: "builders risk policy" (accessed October 2026)https://www.irmi.com/term/insurance-definitions/builders-risk-policy}
3. Handover. Builder's risk ends and the permanent property policy starts. The two dates have to meet.

The handover is where gaps open. If servers arrive while the contractor still controls the site, a builder's risk policy written for the module may not list the operator's GPUs. Lenders funding at delivery ask which policy covers the servers on each day between the dock and the first invoice.

Equipment breakdown

Standard all-risk property policies exclude mechanical and electrical breakdown. Equipment breakdown insurance covers it for nearly any equipment, computers included, and often covers the income lost while it is repaired. ^{[4]IRMI, insurance definitions: "equipment breakdown insurance" (accessed October 2026)https://www.irmi.com/term/insurance-definitions/equipment-breakdown-insurance}

In colocation, a failed transformer is the facility's problem. On an owned site it is the operator's, and a new pad-mounted transformer carried a lead time of 68-113 weeks in 2026. ^{[5]CRE Daily, "Data Center Construction Costs Jump 21% Since 2024," on the Cushman & Wakefield 2026 guide (August 27, 2026)https://www.credaily.com/briefs/data-center-construction-costs-jump-21-since-2024/} The policy pays for the replacement but cannot make it arrive sooner, so the lost-income part matters as much as the repair cost.

When the power plant fails

Business interruption pays lost income after covered damage at the insured site. Damage to the plant that feeds it needs a separate cover.

Utility service interruption coverage pays for loss from a lack of power caused by covered damage to property away from the premises, usually the generating station. It is not in a standard property policy and is added by endorsement. Endorsements vary on whether they cover lost income as well as direct damage, and whether they cover damage to transmission lines. ^{[6]IRMI, insurance definitions: "utility service interruption coverage" (accessed October 2026)https://irmi.com/term/insurance-definitions/utility-service-interruption-coverage} Contingent business interruption, which covers damage at a supplier or customer, does not cover an off-premises power interruption. ^{[7]Daniel Torpey, "Contingent Business Interruption: Getting All the Facts," IRMI (April 2019)https://www.irmi.com/articles/expert-commentary/contingent-business-interruption-getting-all-the-facts}

A fuel cutoff with no physical damage anywhere triggers neither. For a lender, undamaged GPUs on a dead site produce no property claim and no revenue, as Marathon's 2022 Montana outage showed. ^{[8]Marathon Digital Holdings, "Provides Update on Its Bitcoin Mining Operations in Montana" (June 28, 2022)https://ir.mara.com/news-events/press-releases/detail/1287/marathon-digital-holdings-provides-update-on-its-bitcoin-mining-operations-in-montana} The plant and fuel risks behind that are in behind-the-meter GPU deployments.

Liability and fuel

A modular site stores fuel, coolant and high-voltage gear outdoors. When the land is leased, the landowner asks to be an additional insured on the operator's general liability policy, a status a named insured adds to satisfy a contract. ^{[9]IRMI, insurance definitions: "additional insured" (accessed October 2026)https://www.irmi.com/term/insurance-definitions/additional-insured}

• Pollution: property and liability policies can carry a pollution exclusion, which removes coverage for losses from contaminants such as fumes, vapor and chemicals. ^{[10]IRMI, insurance definitions: "pollution exclusion" (accessed October 2026)https://www.irmi.com/term/insurance-definitions/pollution-exclusion} A diesel spill needs a pollution policy of its own.
• Spill plans: the EPA's Spill Prevention, Control, and Countermeasure (SPCC) rule applies to sites that could discharge oil into navigable waters, unless total aboveground storage is 1,320 gallons or less, counting only containers of 55 gallons or more. ^{[11]40 CFR 112.1, Spill Prevention, Control, and Countermeasure rule: general applicabilityhttps://www.law.cornell.edu/cfr/text/40/112.1} Generator tanks count.
• Workers: crews installing and maintaining the site need workers' compensation.

What one fire did to NFN8

NFN8, a Texas bitcoin miner, filed for Chapter 11 in the Western District of Texas on February 2, 2026. A fire at its leased 78,377-square-foot facility in Crystal City, Texas, over the Christmas holidays had cut its mining capacity and revenue by as much as 50%. ^{[12]Chapter11Cases, "Bitcoin Mining Company NFN8 Group Files Chapter 11 After Fire Cuts Capacity in Half," on the first-day filings in the U.S. Bankruptcy Court for the Western District of Texas (February 2026)https://chapter11cases.com/blogs/news/bitcoin-mining-company-nfn8-group-files-chapter-11-after-fire-cuts-capacity-in-half}

NFN8 had insurance and expected proceeds, with timing uncertain. It had also sold its miners to more than 250 counterparties and leased them back on two- to four-year terms. ^{[12]Chapter11Cases, "Bitcoin Mining Company NFN8 Group Files Chapter 11 After Fire Cuts Capacity in Half," on the first-day filings in the U.S. Bankruptcy Court for the Western District of Texas (February 2026)https://chapter11cases.com/blogs/news/bitcoin-mining-company-nfn8-group-files-chapter-11-after-fire-cuts-capacity-in-half}

Having insurance did not prevent the filing. Lease payments keep falling due while a claim on a burned site goes through adjusting, salvage and proof of loss. Property proceeds replace equipment. Business interruption is the line that pays for the months in between.

What lenders need on the certificate

Each party with an interest in the site wants its name on a different policy, in a different capacity.

A loss payee is a party with an interest in insured property that is entitled to some or all of the proceeds, often a lessor. ^{[13]IRMI, insurance definitions: "loss payee" (accessed October 2026)https://www.irmi.com/term/insurance-definitions/loss-payee} A plain loss payee has no greater rights than the insured, so if the insurer denies the insured's claim, it denies the loss payee's too. ^{[14]Big I (IIABA), Ask an Expert: "the difference between a loss payee versus a lenders loss payable form" (accessed October 2026)https://www.independentagent.com/vu_resource/ask-an-expert-strikes-again-with-the-difference-between-a-loss-payee-versus-a-lenders-loss-payable-form/}

The lender's loss payable option in the standard Loss Payable Provisions endorsement (form CP 12 18 from ISO, the Insurance Services Office) gives a creditor the rights a mortgage clause gives a mortgagee. ^{[15]IRMI, insurance definitions: "lenders loss payable endorsement" (accessed October 2026)https://www.irmi.com/term/insurance-definitions/lenders-loss-payable-endorsement} The lender may still be paid when the insured's claim is denied, arson included, if it has met its own duties under the endorsement, and it typically gets advance notice of cancellation. ^{[14]Big I (IIABA), Ask an Expert: "the difference between a loss payee versus a lenders loss payable form" (accessed October 2026)https://www.independentagent.com/vu_resource/ask-an-expert-strikes-again-with-the-difference-between-a-loss-payee-versus-a-lenders-loss-payable-form/}
