Marsh Risk, a business of Marsh, announced the addition of significant capacity to Nimbus, its large-scale data center construction insurance facility. Nimbus now offers limits up to $2.7 billion (up from €1 billion) – inclusive of delay in start-up and business interruption coverage – for major data center construction projects in the UK, US, Canada, Europe, Australia, and New Zealand.

Launched in June 2025 and backed by insurers from Lloyd’s and other markets, Nimbus is currently being deployed on numerous projects in the US, UK, and the Netherlands.

Marsh is helping clients in this sector work with communities to develop business strategies that will enable them to grow sustainably. By harnessing our global resources in critical interconnected areas such as capital management, construction, off-site power generation, environmental risk, and operational resilience, Marsh is enabling data center developers, operators, and owners to strengthen their delivery and resilience as we embrace the age of Industry 4.0.” – Mike Mathews, Global Digital Infrastructure Leader, Marsh.
