The increasing demand for digital infrastructure is prompting communities to consider hosting hyperscale data centres, often presented as low-impact, high-value opportunities generating reliable tax revenue and infrastructure upgrades. However, an emerging analysis suggests a critical oversight in evaluating these projects: their end-of-life implications. Drawing lessons from communities that have hosted nuclear power plants, the report, “After the Servers Go Dark,” argues that while data centres differ from nuclear facilities in workforce intensity and operational footprint, they share a key characteristic: they are large, capital-intensive, place-based assets that eventually close. When this closure occurs, it has the potential to debilitate local economies in ways that are rarely planned for.

The experience of nuclear host communities, documented extensively, offers a stark framework for understanding the potential fallout when a dominant tax-generating asset disappears. These communities reveal the speed and depth of disruption that can occur across fiscal, institutional, and social systems when a major employer and tax contributor ceases operations.

Invisible Dependency on Tax Payments

During the operational life of a nuclear power plant, host communities benefit from sustained economic activity. When closure occurs, the negative effects are often swift, severe, and lasting. This is not solely due to job losses, but because entire local systems become calibrated around a single, large tax-generating entity. Nuclear plants have historically comprised a dominant share of local tax bases, sometimes accounting for over 50% of municipal budgets. Over years, this contribution becomes an assumed, almost invisible, part of the local economy.

When this fiscal contribution stops, municipal budgets can face severe contraction, leading to the closure of essential services like classrooms and fire stations, and widespread layoffs of municipal workers. This sudden fiscal shock occurs precisely when local officials are tasked with finding new revenue streams to maintain service levels and quality of life expectations, a task made exponentially more difficult by their drastically reduced budgets. The situation moves from “doing more with less” to “doing everything with nothing.”

The Murky Future of Decommissioned Sites

Nuclear power plants operate for decades, often becoming symbols of economic prosperity. However, post-closure, they enter a complex, regulated process called decommissioning. This involves decontamination, dismantling, and the termination of operating licenses. Decommissioning is typically funded through a Nuclear Decommissioning Trust (NDT), capitalized over the plant’s operational life. While these trusts can total over $1 billion and fund processes that may take up to 60 years, the fate of the physical site is often complicated.

Utilities, who tend to retain site control, often see little business value in redeveloping former nuclear plant sites, leaving host communities deprived of potential economic development opportunities. This history suggests that the consequences of closure for data centres are not hypothetical but predictable and repeatable if unaddressed.

Practical Considerations for Host Communities

The analysis from “After the Servers Go Dark” offers several practical considerations for communities evaluating data centre development:

Appreciating the Speed of Closure Decisions

Unlike nuclear power plants, which often require advance notice to regulators of planned closures, data centres can cease operations rapidly due to technological shifts, corporate strategy changes, or other factors beyond a community’s control or awareness. Decisions to close a data centre can be precipitated by a “firmware update” rather than a drawn-out process. This means communities need to negotiate for advanced notice of planned closures, perhaps a year in advance, to allow for contingency planning.

Responding to Eliminated Tax Payments

Similar to nuclear facilities, tax payments and other benefits from data centres generally cease abruptly upon closure. To mitigate this, host communities should negotiate tax payment phase-out clauses in hosting agreements. This could involve a period of 5-10 years of payments at pre-closure levels, triggered when operations fall below a certain threshold. Including lump-sum payments to assist with economic development planning for fiscal gaps created by closure is also advisable.

Defining and Completing Facility Decommissioning

While nuclear power plant decommissioning follows a heavily regulated and prescribed process with clear outcomes and robust funding mechanisms, no such systems currently exist for data centres. This leaves host communities with significant uncertainty regarding the physical state of the site after operations cease and the financial responsibility for its remediation and potential redevelopment. Clear agreements must define the scope, timeline, and funding for data centre decommissioning and site remediation.

The report emphasizes that the lesson for potential data centre host communities is not to avoid development, but to plan deliberately for the entire lifecycle of these facilities before development begins. This requires a shift in perspective from viewing data centres solely as immediate economic benefits to understanding them as long-term assets with potential end-of-life liabilities.

Key facts

The rise of data centres presents an opportunity for economic growth, but this analysis strongly suggests that without comprehensive lifecycle planning, communities could face significant fiscal and social challenges when these digital hubs eventually go dark. Failing to plan for the end of a data centre’s operational life could leave communities in a precarious position, mirroring the struggles of those left behind by closed nuclear facilities.
