Data Center Projects Take Flight with Marsh's New Initiative, Nimbus
In a significant move to address the growing demand for data centre infrastructure, Marsh, a leading global insurance broker, has launched a new insurance facility called Nimbus. This innovative offering is designed to provide comprehensive cover for large-scale data centre construction projects across the UK and Europe, with a capacity of up to €1 billion ($1.16 billion) in all-risks construction coverage[1][3].
Key features and benefits of Nimbus include:
1. Broad Construction All-Risks Coverage: Nimbus offers protection against a wide range of risks during the construction phase of data centres, providing clients with extensive risk transfer capability specifically tailored for this complex and capital-intensive sector[1][3].
2. Support from a Panel of Leading Insurers: Nimbus is backed by a panel of insurers from Lloyd’s and other company markets in London and Europe, which brings strong capacity and underwriting expertise to the facility[1].
3. Focus on Large-Scale Data Centres: The facility targets the growing market for substantial data centre projects, reflecting the increasing demand for infrastructure supporting digital economies and cloud computing infrastructures in Europe and the UK[1][4].
4. Innovative Insurance Solution: As a new product launched in mid-2025, Nimbus reflects Marsh’s commitment to innovation in the insurance market for critical infrastructure assets, helping clients manage their total cost of risk with data-driven insights and tailored coverages[1][3][4].
The launch of Nimbus comes amid a surge in data centre construction projects across the region due to increasing demand for more processing and storage power. With Nimbus, clients can manage their critical assets more efficiently and confidently.
In addition to Nimbus, Marsh has also announced the launch of a bespoke Data Centre Risk Management Service to protect vital data assets and real-time services. This service provides risk management and insurance solutions for clients globally throughout the lifecycle of data centre operations.
Marsh's commitment to the data centre sector doesn't stop there. In collaboration with Liberty Specialty Markets and AIG, Marsh has also launched a new insurance and reinsurance facility for green and blue hydrogen energy projects. This facility, designed to support the growing green and blue hydrogen energy market, is a testament to Marsh's forward-thinking approach to risk management and insurance solutions.
Arch Insurance, in partnership with Marsh, has also launched Blue Vault, a solution to provide insurance protection for the secure storage of digital asset private keys in traditional vault facilities. This marks the first time Arch Insurance has offered insurance coverage for digital asset storage.
In conclusion, Nimbus stands out as a dedicated, high-capacity insurance offering designed to meet the specialized needs of constructing modern, large-scale data centres, combining broad risk protection with strong market support that is essential for this rapidly expanding sector[1][3][4]. This innovative insurance facility is set to revolutionize the data centre construction industry, providing a much-needed solution for a sector that is increasingly vital in today's digital economy.
