Insurance firm Aon has expanded the size of coverage it can offer to data center projects.

Aon first launched a new data center-focused insurance product – the Data Center Lifecycle Insurance Program (DCLP) – last year. The multi-line insurance facility spans construction, cargo, cyber, and operational exposure under one program, and is designed to help clients manage risk across every stage of data center development and operations.

The DCLP initially offered coverage of up to $1.5 billion for construction risks, delays in start-up, and operational property damage or business interruption.

The company is now increasing total program capacity to $3.5bn and expanding the program to include coverage for existing data centers coming off the first year of operations.

The insurer said the expansion reflects “accelerating global investment” in the data center space and the “growing importance of resilience” as data centers become larger, more capital-intensive, and more critical to the global economy.

“Data centers have become foundational to innovation, connectivity, and economic growth,” said Joe Peiser, CEO of risk capital at Aon. “As these assets grow in size, complexity, and importance, resilience must be built from the start. By expanding our Data Center Lifecycle Insurance Program and extending coverage to operating data centers, Aon is helping clients anticipate risk, protect critical assets, and invest in digital infrastructure with greater confidence.”

The DCLP still includes up to $400 million for construction cyber attacks as well as technology errors & omissions. Up to $500m is covered for cargo and transport insurance, and up to $200m for third-party liability (excluding US exposure).

Aon is one of several insurance firms that have launched data center-specific insurance products in the last 18 months. Last year saw Marsh launch a new insurance product covering risks related to data center construction. Lockton, another insurance firm, launched a data center SLA insurance product.

S&P Global last week noted that while data centers offer a “meaningful growth opportunity” for the global re/insurance industry, capacity constraints will limit the industry's ability to fully insure hyperscale data center projects, as total insurable values reach $20 billion-$30 billion per location. The nascent data center insurance market could still generate $10bn in new premiums in 2026 alone, however.
