Data Centers Are Entering a New Phase: From Moratoria to Regulations. What Can Romania Learn from the Experience of the United States and Western Europe?
Just a few years ago, competition among states and regions was straightforward: who could attract more investment in data centers. Today, in the world’s most mature markets, the question is no longer whether new data centers should be built, but how they can be developed without placing pressure on power grids, natural resources, and local communities.
An analysis published by Uptime Institute in June 2026—US data center critics pivot from moratoria to regulations, by Rose Weinschenk—shows that the United States is entering a new phase. While many communities have sought to block data center development through moratoria in recent years, the focus is now shifting toward specific regulations that determine who bears the cost of infrastructure and how transparently the impact of these investments must be reported.
The same trend is also visible in Europe.
Why Are These Regulations Emerging?
Artificial intelligence has completely transformed the scale of data centers. New campuses developed for AI workloads consume hundreds of megawatts, equivalent to the energy requirements of entire cities. In many regions, power infrastructure was not designed to accommodate demand on this scale.
As a result, authorities must address a number of legitimate questions:
- Who finances the expansion of the power grid?
- How are residential consumers protected?
- What is the impact on water consumption?
- How are emissions and energy consumption reported?
- What economic benefits remain within local communities?
It is no coincidence that these are precisely the issues dominating the legislative agenda in both the United States and Europe today.
The United States: From Moratoria to Rules

The Uptime Institute analysis reaches a clear conclusion: moratoria are losing ground, while regulations are gaining momentum.
Most U.S. states have recognized that data centers represent strategic investments, generating jobs and significant tax revenue. As a result, few administrations still want to block their development entirely.
Instead, they are seeking to establish clear rules.
Oregon and Wisconsin: Developers Must Pay for Infrastructure
Oregon has adopted one of the firmest approaches to power infrastructure.
New projects must bear the full cost of expanding the power grid, preventing those costs from being passed on to the public.
A similar decision was made in Wisconsin, where the regulator required two data center projects to fully fund the cost of the new power infrastructure. The decision is regarded as a precedent for other states.
Texas and Virginia: Protecting Consumers and Reviewing Tax Incentives
In Texas, the debate is focused on two main areas:
- limiting the impact on energy bills;
- reassessing the tax incentives granted to the industry.
Virginia, the world’s largest data center market, is moving in the same direction. The state is considering reducing certain tax incentives and introducing mechanisms to ensure that new investments contribute more to the development of local infrastructure.
Illinois, California, and New Jersey: Transparency
Other states are taking a different approach.
Illinois, California, and New Jersey are advancing legislative proposals that require operators to disclose information on:
- energy consumption;
- water consumption;
- carbon emissions;
- environmental impact.
The objective is to increase transparency and provide authorities with the data required for infrastructure planning.
Maine: A Rejected Moratorium
There are also examples that illustrate this paradigm shift.
In the U.S. state of Maine, the state legislature approved a moratorium on the development of certain large-scale data centers, but the governor vetoed it.
The argument was straightforward: the investment and jobs generated by these projects are too important to the local economy.
The example is relevant to the industry as a whole: rather than imposing moratoria, authorities are seeking to establish the conditions under which data centers can be developed and integrated into existing infrastructure.
Europe Has Already Been Through This Phase
While the debate is highly visible in the United States, Europe encountered the same challenges even earlier.
Ireland—Power Infrastructure Has Reached Its Limit
Ireland has become one of Europe’s leading hubs for hyperscale providers. Its success has been so significant that power grid operator EirGrid warned that the Dublin area could no longer sustain the same pace of development without posing risks to energy security.
Authorities restricted the approval of new grid connections and introduced additional criteria relating to energy efficiency and the integration of renewable energy sources.
New rules have been introduced since 2025: large data centers must secure 100% of their installed power capacity from their own generation sources and demonstrate that at least 80% of the energy they consume annually comes from new renewable energy capacity.
In March 2026, Pure Data Centres opened Europe’s first off-grid campus. It is not connected to the national electricity grid and operates through its own microgrid, initially powered by natural gas but designed to use biomethane and HVO fuel.
The Netherlands—From Enthusiasm to Strict Rules
The Netherlands has undergone a similar shift.
Following a temporary moratorium on hyperscale projects, authorities introduced strict criteria governing data center locations, energy consumption, land use, and the impact on local communities.
Development continues today, but under far more restrictive conditions than just a few years ago.
Meta’s Zeewolde project remains the best-known European example. Although local authorities had approved the development of the hyperscale campus, public opposition over energy consumption, the use of agricultural land, and limited economic benefits prompted Meta to abandon the investment.
What Do the United States and Europe Have in Common?
Although their approaches differ, the overall direction is the same.
It is no longer enough for a data center simply to bring investment. Operators must demonstrate that they:
- do not pass infrastructure costs on to the public;
- use energy and water efficiently;
- report their environmental impact transparently;
- contribute to the development of local communities.
In practice, the debate has shifted from “whether to approve construction” to “who pays the costs of development.”
Mature markets are approaching saturation. Virginia, Dublin, Amsterdam, and Frankfurt have one thing in common: they have attracted massive investment for more than a decade and are now facing shortages of available land, difficulties in securing power, increasingly complex permitting procedures, and, above all, opposition from local communities.
Romania Has an Opportunity It Should Not Miss
This situation brings Romania’s opportunity back into focus.
Compared with Europe’s major data center hubs, Romania is starting from a different position.
It still offers several important advantages:
- available capacity for infrastructure development;
- competitive costs;
- excellent connectivity to Central and Eastern Europe;
- a strategic location on the Black Sea;
- significant potential to expand renewable energy generation.
In addition, AI-driven demand is creating opportunities for the development of new campuses dedicated to HPC, AI inference, and regional cloud services.
As expanding capacity in Western European markets becomes increasingly difficult, Romania could become one of the natural destinations for the next wave of investment.
But This Opportunity Also Requires Clear Rules
Precisely because Romania is at a different stage of development, now is the right time to define a predictable legislative framework capable of reducing potential friction among investors, utility operators, and local communities.
A modern regulatory framework could provide both investors and local authorities with the clarity required for long-term development.
Such a framework could include:
- clear rules governing connections to the power grid;
- mechanisms through which developers contribute to the cost of new infrastructure;
- reporting standards for energy and water consumption;
- independent environmental impact assessments;
- incentives for the use of renewable energy and the recovery of waste heat;
- transparent mechanisms for dialogue with local communities.
The experience of the United States and Western Europe sends a very clear message: data centers are no longer viewed solely as technology investments, but as critical infrastructure that must be responsibly integrated into the energy and urban ecosystem.
Mature markets have reached a point at which development is constrained by infrastructure and public acceptance. Romania has not yet reached that point, and this represents a major competitive advantage. Romania should not copy the Irish or Dutch model, but instead take advantage of the fact that it is still in a growth phase and can establish clear rules early on.
