In June 2026, the European Commission launched a paradigm shift with its "Technological Sovereignty Package": Europe must no longer depend on non-European providers for its critical digital infrastructure. At the center of this initiative is the expansion of sovereign data center capacity — from the current 12 gigawatts to 60 gigawatts by 2035. The investment volume: up to €200 billion. The decisive question for investors and infrastructure partners is: who owns the assets?
The EU Technological Sovereignty Package: Framework and Ambitions
The package presented in June 2026 by Executive Vice-President Henna Virkkunen encompasses four strategic pillars:
Cloud and AI Development Act (CADA): The cornerstone of the package mandates public authorities to store critical data in EU-owned data centers. A four-tier sovereignty ranking evaluates control over supply chains and infrastructure. For hyperscale owners with European asset ownership, this creates a structural competitive advantage over US-based hyperscalers.
AI Gigafactories: The EU plans up to seven large-scale data centers with a total volume exceeding €30 billion (€10bn public, at least €20bn private). The EuroHPC Joint Undertaking tender runs until November 2026, with first construction planned for 2027. Individual sites receive up to €1 billion in funding.
Chips Act 2.0: The target is a 20 percent EU share of global semiconductor production by 2030 — a factor that further accelerates demand for high-performance computing infrastructure in Europe.
Energy Roadmap: Given a projected fivefold increase in data center energy demand, the EU focuses on sustainable energy integration and AI-assisted grid management.
Why Own-and-Hold Is Decisive
The political debate around sovereignty falls short when it focuses solely on data protection and regulation. Genuine digital sovereignty requires that physical infrastructure — land, buildings, energy supply, grid connections — remains in European hands and is held long-term.
The Colocation Dilemma
Traditional colocation models, where operators lease space in third-party data centers, create no structural independence. Leases expire, owners can change terms, and strategic control over critical infrastructure remains with the landlord. For sovereign AI infrastructure, this represents a systemic risk.
Own-and-Hold as an Infrastructure Strategy
The own-and-hold model — long-term ownership of hyperscale data centers — offers structural advantages:
- Planning certainty: Asset ownership enables 15-25 year investment horizons that are attractive to institutional investors (pension funds, infrastructure funds).
- Energy sovereignty: Owners can structure energy supply contracts (PPAs, LNG supply agreements, grid connections) directly and long-term — without dependence on third parties.
- Regulatory compliance: CADA-compliant infrastructure requires demonstrable European ownership, not merely European operation.
- Value appreciation: Hyperscale data centers in strategic locations develop into core infrastructure assets with stable, inflation-protected cash flows.
The Energy Factor: Supply Security as a Sovereignty Issue
Tripling European data center capacity by 2035 poses a historic challenge for energy supply. According to the IEA, global data center electricity consumption could nearly double to approximately 945 terawatt-hours by 2030. In Germany, connected capacity for AI data centers is projected to rise from 530 MW to 2,020 MW by 2030.
Grid Connection Bottleneck
In established hubs like Frankfurt, grid connections are partially unavailable until the mid-2030s. New hyperscale projects are therefore being developed an average of 175 kilometers from traditional hubs — compared to 46 kilometers for projects from 2022 to 2025. Regions with energy surpluses from wind power (northern and eastern Germany) are gaining strategic importance.
Hybrid Energy Models
Sovereign data center infrastructure requires hybrid energy strategies:
- Power Purchase Agreements (PPAs): Long-term direct contracts with renewable energy producers secure green power supply and price predictability.
- LNG as a bridge technology: Liquefied natural gas enables baseload-capable on-site power generation in regions with insufficient grid connections — a critical factor for commissioning new sites.
- Grid integration: Owners with direct grid access can utilize demand response mechanisms and contribute to grid stability — an increasingly regulatory-required feature.
Site Selection: Permitting, Grid, Water, Energy
Germany's National Data Center Strategy (March 2026) targets a doubling of capacities by 2030. Success depends on accelerated permitting procedures and prioritized grid connections. For own-and-hold investors, this means:
Permitting risk: Planning and approval procedures in Germany take significantly longer than the EU average. Experienced infrastructure partners with local expertise are critical.
Water availability: Modern hyperscale facilities use closed-loop cooling systems and cooling towers to minimize water consumption. Sites with secured water supply have a structural advantage.
Grid capacity: Regions with existing high-voltage infrastructure — such as former industrial sites or former coal mining areas — offer faster grid connections and lower development costs.
Institutional Financing: Data Centers as Core Assets
Data centers have become a core component of institutional infrastructure portfolios in 2026. At conferences such as Data Centre Capital 2026 in London and specialized financing forums in Amsterdam, the bankability of projects is in focus: risk management, deliverability, and secured energy supply.
Key trends in financing:
- Hybrid energy models: Investors prioritize projects with integrated on-site power generation and long-term PPAs.
- Institutional allocation: Infrastructure funds, pension funds, and sovereign wealth funds are increasing their allocation to digital infrastructure.
- Strategic partnerships: Infrastructure funds and energy technology providers pool capital to shorten "time to power" for new sites.
For own-and-hold owners with secured energy supply and CADA-compliant infrastructure, this creates a structurally preferred position in the competition for institutional capital.
ArcTeron: European Own-and-Hold Owner and Energy Partner
ArcTeron positions itself as a European owner and financier of hyperscale data centers with a target of 5 gigawatts of capacity. The own-and-hold model combines long-term asset ownership with integrated energy partnership: grid connection, gas/LNG supply, and hydrogen readiness.
This combination directly addresses the requirements of the EU Technological Sovereignty Package: European ownership, secured energy supply, and long-term infrastructure stability — without dependence on non-European hyperscalers.
Conclusion: Sovereignty Begins with Ownership
The EU Technological Sovereignty Package sets the political framework. Implementation requires owners who invest long-term, secure energy, and meet regulatory requirements. Own-and-hold is not merely an investment strategy — it is the foundation of genuine digital sovereignty in Europe.
For institutional investors, energy providers, and infrastructure partners, the current market environment offers a historic opportunity: demand for sovereign hyperscale infrastructure exceeds available supply — and will continue to do so for the foreseeable future.
