Nimbus, which launched in June for the UK and Europe, is backed by a panel of insurers from Lloyd’s and company markets. It combines construction all-risks, delay in start-up, property damage, and business interruption cover.
The facility provides up to $1 billion in construction all-risks coverage and up to $365 million in additional cover for delay in start-up. Since its launch, Nimbus has been used in projects including data center developments in the UK, France, and the Netherlands.
The expansion comes as demand for data centers continues to grow, driven by increasing cloud adoption, investment in artificial intelligence, and the need for secure storage and processing capacity. Rising power requirements, land availability, and sustainability considerations are also influencing the sector, creating demand for risk transfer solutions that address both financial exposures and operational resilience.
Jim Dunn, head of US Construction, Marsh, said: “Data center construction in the US is experiencing unprecedented growth, driven by the rapid adoption of cloud computing and digital transformation initiatives. Over the past five years, the sector has achieved a compound annual growth rate of 12%, reflecting the increasing demand for secure, scalable infrastructure. Marsh's Nimbus data center solution is specifically designed to support this surge, offering innovative risk management strategies tailored to the evolving needs of our clients. We are committed to providing industry-leading support to sustain this momentum and to promote the development of resilient, future-ready data infrastructure across the country.”
For insurers, facilities like Nimbus allow multiple carriers to pool capacity to support projects that would otherwise exceed individual risk appetites.
By spreading exposures across several participants, insurers can engage in large-scale infrastructure projects while managing capital requirements. The facility structure also streamlines placements, giving insurers a more efficient route to access risks that are often complex and global in nature.
New appointment
Marsh also appointed Kate Fairhead as UK Data and Digital Infrastructure leader for Construction, Marsh Specialty.
Fairhead, who joined Marsh in 2015 through the Marsh Graduate program within the Construction business, is based in London and leads a team focused on insurance placements for clients in the data centre sector. She has supported a range of large-scale construction projects across Europe and has experience in advising clients on risks related to financing, operational disruption, and regulatory compliance.
In her new role, she will oversee the development of insurance strategies for companies investing in digital and energy infrastructure, working closely with both developers and insurers.
