Marsh Risk, a global insurance broker, has expanded capacity for Nimbus, its dedicated large-scale data centre construction insurance facility, increasing available limits to $2.7bn for major developments across multiple international markets.
The expansion significantly raises the level of insurance protection available to data centre developers undertaking complex construction projects.
Nimbus now supports large-scale developments across Europe, North America, and Australia, reflecting the growing capital requirements and risk exposure associated with modern digital infrastructure projects.
Following the latest expansion, the facility provides a broad suite of coverage options, including delay in start-up and business interruption protection. These features are designed to address the financial and operational risks that can arise during extended construction timelines or unforeseen disruptions.
The facility is currently available for projects in the UK, the United States, Canada, Europe, Australia, and New Zealand.
Nimbus has already been deployed on multiple developments in the US, UK, and the Netherlands, demonstrating its application across a range of jurisdictions and project scales. This deployment highlights the increasing complexity and global footprint of data centre construction as demand for digital infrastructure continues to rise.
The expansion comes amid accelerating demand for data centres driven by growth in artificial intelligence, cloud computing, and digital services. As these technologies scale, data centre projects are becoming larger, more capital intensive, and more critical to national and regional economies, increasing the need for tailored insurance solutions.
Marsh provides risk advisory and insurance brokerage services across a wide range of industries, with dedicated expertise in digital infrastructure. Through Nimbus and its Global Digital Infrastructure team, the firm offers access to London market capacity backed by A-rated insurers, alongside specialist capabilities spanning construction, cybersecurity, energy, and power risk.
Beyond insurance placement, Marsh supports clients in protecting capital investments, managing operational assets, and scaling infrastructure in an increasingly interconnected digital economy. The firm combines technical risk knowledge with global market access to address the evolving risk profile of data centre developments.
Marsh Global Digital Infrastructure leader Mike Mathews said, “Demand for more powerful and efficient data centres is accelerating technological innovation, particularly around AI and machine learning, which will revolutionise the way we live and work and reshape economic landscapes over the next decade.”
Marsh Global Digital Infrastructure leader Mike Mathews added, “By harnessing our global resources in areas such as capital management, construction, power generation, environmental risk, and operational resilience, Marsh is enabling data centre developers, operators, and owners to strengthen their delivery and resilience as we embrace the age of Industry 4.0.”
