EU Data Centers and Energy Policy: Sustainability Rules, Power Demand, and What Comes Next

As AI drives a surge in electricity demand from data centers, the European Union and its member states are introducing new regulations to ensure sustainability—while still supporting digital growth

Key Takeaways

• With development of data centers creating a surge in energy demand—and economic development —governments across the European Union are attempting to balance development of data centers with sustainability goals.
• In recent years, the European Commission has enacted policy and funded programs to ensure energy efficiency and sustainability in data centers. Meanwhile, member states are taking their own measures.
• Policymakers, data center developers, and other stakeholders will need to balance increasing demand for digital services while ensuring sustainable data center development.

To catch up with the digital development of the US and China, Europe needs to develop high-capacity data centers to meet mounting demand for computing capacity, the latter largely driven by artificial intelligence (AI). Yet building data centers where AI models are hosted and trained requires significant investments and consumes massive amounts of energy.

The cost to construct a data center in major European markets (the “FLAP-D” metropolitan areas around Frankfurt, London, Amsterdam, Paris, and Dublin) ranges from 8.7 to 13.4 million Euro/MW (10 to 15.4 million $USD/MW), while the price tag for active information technology (IT) components can run as high as 21.7 million Euro/MW (25 million $USD/MW). The International Energy Administration estimates that data centers’ electricity consumption where AI models are trained is equivalent to that of 100,000 households—and that the largest data centers now under construction could consume twenty times as much.

Data centers’ global electricity consumption is expected to more than double by 2030, increasing concerns about the impact that such rapidly growing demand will have on the energy system and the decarbonization process—and whether existing networks can meet it. To mitigate these risks, policymakers and regulators are pushing for data centers to be sustainable, requiring the use of renewable energy (as much as possible) and efficiency efforts to minimize the impact on power grids and cooling resources (mainly water).

That call has been heeded by the European Commission and governments across the European Union (EU). Below, we highlight key policy initiatives and considerations for stakeholders moving forward.

EU Policy Efforts to Improve Data Center Energy Efficiency

In 2020, the European Commission stated its vision for digital technologies, pointing out the need for data center development to be sustainable and climate neutral. This was reaffirmed in the Commission’s 2022 policy program to promote digital development.

Additional actions took place in 2023, 2024, and 2026. In 2023, the Commission issued a directive on energy efficiency providing for it to establish a European database reporting data on key performance indicators (KPIs) of data centers with a power demand of at least 500 kW of installed IT. In 2024, the Commission followed with a delegated regulation to set out the information and KPIs to communicate to the European database to use to establish an EU rating scheme to assess the data center’s energy performance, water footprint, and overall sustainability. Finally, in late March 2026 the Commission published for consultation a draft regulation on the structure of the common EU rating scheme. The consultation will close on 23 April 2026.

A Data Centre Energy Efficiency Package, including the rating scheme, is expected in the second quarter of 2026. It will contain an assessment of the data submitted under the aforementioned reporting program, introduce a rating scheme for data centers in Europe, and initiate work on minimum performance standards for such facilities. Meanwhile, the Commission’s Directorate-General for Energy commissioned a study to identify minimum performance standards for data centers in Europe.

How EU Member States Regulate Data Centers

During the same time period, individual member states have been addressing data centers’ energy efficiency with local measures intended to 1) incentivize data center development, which is needed to enhance economic development and competitiveness; and 2) mitigate impacts on the energy system and decarbonization process by imposing strict environmental requirements.

Examples include:

• France offers fiscal incentives to attract investment and introduced a fast-track procedure for connecting large data centers located on sites it designates as favorable. Connection is subject to availability confirmation from the transmission system operator. A site is deemed “favorable” if the land area is fit to accommodate large projects; the site is close to the 400 kV network (extra-high voltage network); and, given upstream network constraints, the site allows access to high-voltage electricity via re-dispatching.
• Ireland provides fiscal and financial incentives for data centers adopting sustainability measures. The country also recently adopted stricter rules for data centers to connect to the grid, requiring new facilities to source at least 80 percent of their annual power consumption from newly installed renewable energy plants in the country; and obtain dispatchable generators or batteries at the facility or nearby.
• The Netherlands provides fiscal incentives for energy-saving technologies, including those applied to data centers. However, the rapid increase in data centers has caused concerns about grid capacity in areas where connection requests are high. For instance, Amsterdam’s municipal government paused new data center buildouts or expansion of existing data centers due to insufficient grid capacity.
• Germany plans to incentivize development of AI data centers to double capacity by 2030. The effort sends municipal business taxes to municipalities that attract new centers (and not to the municipality where a company’s headquarters is located); implements regulatory reviews to support collaboration among companies along the AI supply chain; and encourages investments from European and third countries, among others.
• Italy published in November 2025 a national strategy to attract industrial investments in data centers and, in February 2026, approved a law decree that simplifies the authorization procedures for data centers. Parliament has begun the process to convert the law decree into law. In the meantime, Parliament is discussing a proposed law that delegates the government to regulate development of data centers.

Key Considerations for EU Policymakers and Data Center Developers

As AI accelerates demand for digital infrastructure, Europe will face the challenge of expanding data center capacity while maintaining energy security and climate commitments.

No single model exists for developing such capacity; current projects around the world illustrate that different technological pathways can support sustainability goals. In many European countries, renewable energy sources integrated into the grid increasingly power data centers. In the United States, some data centers rely on behind-the-meter thermal generation combined with carbon capture and storage to manage emissions and ensure reliable power supply.

The approach a given country adopts will depend largely on its local conditions, including the structure of its power system, availability of renewable resources, grid capacity, industrial policy priorities, and planning frameworks.

As a starting point, policymakers should prepare a comprehensive assessment of several key factors:

• First, governments should evaluate how much data center capacity is actually needed—and over what timeframe.
• Second, governments should assess what makes investments in data centers attractive in their specific context (e.g., access to fiscal and/or financial incentives, streamlined connection processes to electricity networks, reliable electricity supply).
• Third, policymakers should assess which energy requirements (e.g., renewable power procurement, energy-efficient cooling systems, waste-heat reuse, low-carbon backup generation) are best suited to achieve sustainability and reliability objectives in their specific context.

Effective coordination will be essential. Energy planning, digital infrastructure policy, grid investment, and permitting processes must be aligned so that data center development supports both economic growth and climate targets consistently with broader energy and sustainability goals.
