A new Marsh property insurance exchange called Stratus is designed to address the risks of data centres and other digital infrastructure projects as they move to operation.

Stratus extends Marsh’s construction phase insurance facility Nimbus.

It provides access to up to $US10 billion ($13.93 billion) in property insurance capacity on a single-placement basis for the global exposures of US-domiciled companies.

Thirty traditional and alternative capital provider participants will evaluate each risk individually. Marsh says this allows providers to better assess, quantify and diversify risk, and address aggregation concerns arising during the operational phase of projects.

Marsh Risk US property digital infrastructure leader Joe Macejak says as large projects shift from construction to operation, risks become greater, driven by multibillion-dollar sites, power systems and technology used in processing units and critical equipment.

“Stratus is designed to improve the quality and efficiency of operational digital infrastructure property placements and help clients secure the protection they need to support growth at scale,” he said.

Stratus will launch as a property-focused solution, with plans to expand into other insurance lines, including inland marine, cyber and casualty, to form a single access point for operational digital infrastructure clients.

Stratus and Nimbus can be engaged separately or together.
