Ten months. One procedure. One competent authority.
For anyone developing data centers in Italy, Law no. 49 of April 10, 2026 — converting Decree-Law 21/2026, the so-called "Energy Bill Decree" — is the most significant regulatory change in years. In force since April 19, its Article 8 introduces what the industry had been asking for: a single authorization procedure for building and expanding data centers.
Until now, building a data center in Italy meant chasing dozens of permits across different administrations, with unpredictable timelines. Now the path has one entrance, one perimeter and one deadline.
What Article 8 provides
The core of the rule is simple to state: the authorization to build and expand data centers — including connection networks of any voltage — is issued within a single procedure by the authority competent for the Integrated Environmental Authorization (AIA/IPPC).
The single permit absorbs into one process:
- Environmental Impact Assessment (EIA/VIA) — with halved deadlines
- Integrated Environmental Authorization (AIA)
- Landscape and cultural heritage authorization
- Water use permits
- Atmospheric emissions permits
Everything runs through a single conference of services (asynchronous, under Art. 14 of Law 241/90) involving all relevant administrations: environment, landscape, cultural heritage, health and public safety.
Who decides: the competence thresholds
| Nominal thermal power | Competent authority |
|---|---|
| ≥ 50 MW | Region or Autonomous Province |
| ≥ 300 MW | Ministry of Environment and Energy Security (MASE) |
A choice made for clarity: no delegation to sub-provincial bodies for projects subject to regional or provincial AIA. Developers know from day one which administration they will deal with throughout the process.
The timeline: 10 months, hardly a day more
The procedure must be completed within ten months from the verification of documentation completeness. Extensions are allowed only in exceptional cases — nature, complexity, location or scale of the project — and for a maximum of three months.
But beware of one deadline that can prove costly: after the EIA screening outcome, the applicant has 90 peremptory days to file the complete application. Arrive late or incomplete, and you start over.
The legislator's message is clear: the fast lane exists, but it is reserved for mature projects. The required documentation — design documents, environmental studies, sector analyses — must be prepared before, not during.
Strategic projects: the commissioner track
For projects declared of national strategic interest (under Art. 13 of Decree-Law 104/2023, typically investments above one billion euros) the path is even more direct: a single procedure managed by a Special Government Commissioner, whose authorization replaces every other required permit.
What the law does not solve
Intellectual honesty: the single procedure is no magic wand. Early commentators flag at least three open issues:
- No automatic zoning variance. The procedure assumes that compatibility with urban planning instruments has already been secured through ordinary channels. If the site is not zoned correctly, the problem remains upstream.
- The power grid is still the bottleneck. As of January 31, 2026, grid connection requests pending in Italy amounted to almost 79 GW. Faster data center permits alone do not create grid capacity.
- Technical complexity is front-loaded. Preparing an upfront dossier covering EIA, AIA, landscape, water and emissions requires integrated engineering, environmental and legal expertise from day zero.
Meanwhile the framework keeps evolving: Lombardy has passed the first regional data center law (Regional Law 11/2026), and Parliament is advancing the Data Center Framework Act (approved by the Chamber of Deputies on February 24, 2026), which aims to reclassify data centers as national strategic infrastructure.
What about the SEZ? The million-euro question
There is a regulatory intersection almost nobody has explored yet: how does the new Art. 8 single procedure coordinate with the single authorization of the Southern Italy Special Economic Zone (ZES Unica, Decree-Law 124/2023), which already has its own digital one-stop shop and fast tracks?
For those — like us — developing a data center precisely in a SEZ area, this is the most relevant operational question of 2026. The answers are not trivial and deserve a dedicated deep dive: it will be the subject of our next article.
What this means for ITH
The Apulia Tech Hub project — a 140MW TIER IV AI-Native data center in Puglia — lives exactly inside this new framework:
- Relevant scale: the competence thresholds of Art. 8 are our daily playing field
- Mature project: the "project first, fast lane second" logic rewards those who have already invested in engineering, environmental studies and grid connection
- SEZ location: our site combines the tax advantages of the ZES Unica with the new national simplifications
A more predictable timeline means one thing: Italy becomes more competitive in attracting the capital that today chooses Frankfurt, Paris or Madrid.
Conclusion
Article 8 of Law 49/2026 does not eliminate complexity: it organizes it. Ten months with a single counterpart is a paradigm shift, but the fast lane only rewards those who show up prepared.
For Southern Italy, adding up the single procedure, the ZES Unica and the availability of renewable energy, the window of opportunity has never been this open.
