Summary
- Aon is reportedly preparing an operational data centre property facility targeting up to $10bn of insurance capacity.
- The proposed cover would serve projects moving from construction into operation as well as established data centre portfolios.
- Increasing campus scale and concentrated equipment values are forcing insurers to consider data centre risk across the complete asset lifecycle.
Aon is reportedly preparing an operational property insurance facility targeting up to $10 billion of capacity for data centres, extending its existing lifecycle programme beyond construction into long-term operating risk.
The Insurer reported on 9 September, citing two reinsurance broking sources, that Aon intends to take the proposed Operational Property Data Center Lifecycle Insurance Program to insurers as early as next week.
Aon has not formally announced the $10 billion target, so the figure remains a reported market-development target rather than confirmed placed insurance capacity.
The proposed facility is designed to provide permanent property cover for projects completing Aon’s existing construction programme and moving into service. It is also expected to be available for established operational data centre portfolios.
The structure would extend work Aon has already undertaken around the data centre development lifecycle. In July, the broker formally expanded its Data Center Lifecycle Insurance Program to up to $5 billion, building a package intended to combine construction, cargo, cyber, operational, and other risks around large digital-infrastructure developments.
Aon’s own documentation describes the existing programme as an integrated offering spanning property, liability, construction, delay in start-up, business interruption, cyber, cyber property damage, technology errors and omissions, marine cargo, and related exposures. Cover can also extend to terrorism and other specialist risks.
The move towards a dedicated operational property facility reflects how the risk profile changes when a data centre enters service. During construction, insurers are concerned with project damage, equipment in transit, delays, contractor exposure, and the financial consequences of missing the planned ready-for-service date.
Once operational, the concentration of value shifts towards the facility, installed electrical and mechanical systems, computing equipment, revenue commitments, and the cost of an interruption. A failure that leaves a hyperscale campus unavailable can create losses well beyond the physical repair bill.
The increasing physical scale of AI infrastructure adds another difficulty. Larger campuses can concentrate enormous values in buildings located close together and dependent on common electrical, cooling, fuel, water, or network infrastructure. A single regional weather event or shared utility failure can therefore affect several insured assets at once.
Aon has separately highlighted that accumulation risk, arguing that insurers increasingly need to understand exposure at cluster level rather than assess each building as a completely isolated asset. Site spacing, natural hazards, utility dependencies, fire protection, and engineering standards all influence how much capacity insurers are willing to commit.
That creates a direct relationship between facility engineering and the cost and availability of insurance. Design decisions around electrical redundancy, cooling architecture, flood protection, fire separation, and business continuity do not simply determine resilience after construction; they can affect whether underwriters are prepared to support the asset at the required limits.
The reported $10 billion target would place substantial additional insurance capacity behind that operating phase if Aon succeeds in securing sufficient support from carriers. The Insurer said the broker would compete with other emerging data centre insurance platforms as the market responds to rapid growth in infrastructure investment.
For developers and investors, continuity between construction and operations can reduce the risk of reaching commissioning with an asset whose permanent insurance requirements have not been fully resolved. That becomes increasingly relevant where financing agreements impose specific coverage requirements and facilities carry high replacement values.
Until Aon confirms the operational programme, the proposed limit, participating insurers, and policy structure remain subject to change. What is already clear is that insurance capacity is becoming another constraint to manage alongside power, planning, cooling, construction, and financing as data centre projects grow larger and more concentrated.
