Best Data Center & Digital Infrastructure Lawyers in Acharnes

About Data Center & Digital Infrastructure Law in Acharnes, Greece

Acharnes is a suburban municipality in the Attica region close to Athens. The area is attractive for data center and digital infrastructure projects because of its proximity to the capital, available industrial zones, and connections to major power and telecom networks. Legal work for data center projects in Acharnes sits at the intersection of land-use and construction law, energy and grid-connection rules, environmental and fire-safety regulation, telecommunications and electronic communications law, and data protection and cybersecurity obligations under EU and national law.

Because data centers are capital-intensive and highly regulated facilities, planning and permitting require coordinated approvals from municipal and regional authorities, energy operators, telecom carriers and several national regulators. Projects also must meet technical standards for electrical, mechanical and fire-suppression systems and comply with obligations for personal data protection and critical infrastructure security when applicable.

Local Laws Overview

Several legal regimes converge on data center projects in Acharnes. Key points to consider include the following.

Land-use and planning - Municipal zoning rules and regional planning determine where data centers may be sited. Building permits - known in Greece as "oikodomiki adeia" - are required for construction and major fit-outs. The local municipality of Acharnes and the Decentralized Administration of Attica administer planning and building permit procedures.

Environmental regulation - Projects may need environmental permits or environmental impact assessments depending on scale, energy use and emissions. The Ministry of Environment and Energy oversees environmental permitting and Natura 2000 protections may apply in sensitive areas.

Energy and grid connection - Grid connection and transmission issues are governed by the Regulatory Authority for Energy (RAE), the Independent Power Transmission Operator - ADMIE (IPTO) - for transmission-level matters and Hellenic Electricity Distribution Network Operator - HEDNO - for distribution connections. Permits and connection agreements often require technical studies, guarantees and adherence to grid codes.

Telecommunications and electronic communications - The Hellenic Telecommunications and Post Commission (EETT) regulates electronic communications. Interconnection, use of public telecom infrastructure and carrier access can affect site selection and costs. Multiple carriers are typically needed for diversity and redundancy.

Data protection and cybersecurity - GDPR applies to personal data processing performed by data centers hosting services in Greece. The Hellenic Data Protection Authority monitors compliance and issues guidance. At the same time, EU cybersecurity rules such as the NIS Directive and its successor NIS2 impose obligations on operators of essential services and certain digital service providers, which may include large data centers, for incident reporting and security measures. Greece has implemented national measures that mirror these EU obligations.

Fire, safety and technical standards - National building and fire-safety codes, technical specifications for electrical and mechanical installations and international standards for data center design influence permitting and inspection. Fuel storage for backup generators, suppression agents, noise limits and emissions are regulated at municipal and national levels.

Commercial and contract law - Service-level agreements, liability caps, intellectual property allocation and tariffs are governed by general civil and commercial law backed by sectoral regulatory requirements when they apply.

Frequently Asked Questions

What permits do I need to build a data center in Acharnes?

You typically need a building permit, environmental permit or screening determination, and specific approvals for fuel storage, fire-suppression systems and electrical installations. Grid connection approvals from ADMIE or HEDNO and any telecom access agreements are separate. The exact package depends on project size and the chosen site.

How do I secure a reliable power supply and grid connection?

Start early with technical studies and formal application to the transmission or distribution operator to reserve capacity. You may need to negotiate connection agreements, pay network reinforcement costs and obtain guarantees. Consider backup power options and explore power purchase agreements to secure long-term supply.

What local zoning issues should I check for a chosen site in Acharnes?

Confirm permitted land uses, setback and height rules, noise and emissions restrictions, and whether the site is in an industrial or special planning zone. Check for conservation designations or infrastructure corridors that limit development. The municipal planning department can advise on zoning and permitted uses.

Do I need to comply with GDPR if the data center only hosts third-party data?

Yes. GDPR obligations attach to entities that process personal data, including data center operators that act as processors and their customers who act as controllers. Processors must implement appropriate technical and organizational measures and sign data processing agreements reflecting GDPR requirements.

Are data centers considered critical infrastructure in Greece?

Some data centers may fall under critical infrastructure or essential services categories for national security and continuity reasons. If so, they may be subject to specific security, reporting and resilience obligations under national implementations of EU cybersecurity rules. Legal advice can help determine whether those categories apply to your facility.

What environmental rules are most relevant to data centers?

Energy consumption, greenhouse gas emissions from backup generators, noise from cooling and generators, wastewater from cooling systems and hazardous material handling are common environmental concerns. Projects with significant environmental impacts may require an environmental impact assessment. Local and national environmental authorities will set specific conditions.

How should I structure contracts with carriers and cloud providers?

Contracts should define service levels, uptime commitments, remedies and penalties for outages, escalation and incident-response procedures, cybersecurity and data protection responsibilities, indemnities and limits of liability, and termination rights. Consider clear allocation of responsibilities for physical security, access control and maintenance windows.

What fire-safety and technical standards apply?

National fire-safety codes govern fire detection, suppression and emergency response. International best practices for data centers such as electrical redundancy, UPS systems, cooling redundancy and building materials are commonly required by insurers and lenders even when not strictly mandated by law.

How do I handle licensing or registration with regulators?

Depending on activities you may need to register or notify regulators such as the Hellenic Data Protection Authority, EETT for telecom services or energy regulators for specific operations. Licensing requirements vary by activity and scale, so seek legal and regulatory advice early in the project.

What are common legal risks during construction and operation?

Common risks include delays in permitting or grid connection, disputes with contractors or landlords, environmental violations, breaches of data protection rules, insufficient redundancy leading to contractual liability, and regulatory enforcement for noncompliance. Risk allocation in contracts, thorough due diligence and compliance programs help mitigate these risks.
