# Ampervia Capital

> Ampervia Capital is a data center infrastructure capital company focused on Europe. It works in two phases: first, Ampervia and its Club members secure a site and its grid capacity and take it to ready-to-build through a vehicle for that one site; second, institutional capital and banks fund the build. Its public data product is the Ampervia Powered-Land Map, and it publishes open data and sourced answers on data center power and land.

## Two phases

- Phase 1 (Club members): The smaller, earlier, riskier step: land control, the grid connection and permits. Ampervia brings each site into the Club deal room; members who want to invest join a dedicated vehicle for that one site.
- Phase 2 (institutions): Once a site is ready-to-build, the build is funded by infrastructure funds, family offices, operators and banks, or the ready site is sold to one of them.

## Questions

### What is Ampervia Capital?

A data center infrastructure capital company focused on Europe. It secures sites and grid capacity with its members, takes them to ready-to-build, and brings institutional capital in for the build.

### What is the Ampervia Club?

A paid membership and private deal room for qualified investors. Members see every site Ampervia works on and may choose, deal by deal, to co-invest in the vehicle that takes a site to ready-to-build. Membership is not itself an investment.

### What happens when a site reaches ready-to-build?

It can be sold to an operator or developer, or carried into the build with institutional capital. Members of that site’s vehicle choose whether to take their share of the sale or continue.

### What is the Ampervia Powered-Land Map?

The public index of verified powered land for data centers, redacted to zone level and free to explore. It is the research layer behind Ampervia’s pipeline.

### Does Ampervia publish site locations?

No. Public pages carry aggregates only. Site identities and evidence files are released to Club members and under engagement.

# How do data center SPVs and club deals work?

> A sponsor forms a company (the SPV) to hold one site; a small group of investors buys shares or lends to it; the SPV buys or options the land, secures power and permits, then sells the site or brings in build capital. Each project stands alone, so investors choose deal by deal instead of committing to a blind pool.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/data-center-spv-club-deal/

## Typical structure

- **SPV:** one company per site, holding the land and permits.
- **Sponsor:** finds and runs the project, often co-invests, and earns fees or a share of profits.
- **Investors:** provide equity, receive returns when the site is sold or refinanced.
- **Documents:** shareholder agreement, investment memorandum, valuation and exit rights.

## Rules to check

Pooling money from several investors can bring a vehicle under EU alternative-investment-fund rules (an AIFM) or national securities law. Where investors live, how the deal is marketed and who manages it all matter. Take legal advice before raising money.

## Rights investors usually negotiate

- Independent valuation at exit or refinancing.
- Tag-along on a sale.
- Information rights and reporting.
- Limits on sponsor fees and dilution when new capital enters.

## Questions

### Is a club deal a fund?

Not necessarily, but it can be treated as one depending on how it is structured and marketed. Counsel decides.

### What happens at ready-to-build?

The SPV can sell the site, or raise build capital; existing investors may cash out, roll over, or be diluted.

# How can investors invest in data centers in Europe?

> Through four main routes, from most to least liquid: **listed shares** (REITs and operators), **private funds**, **co-investment or club deals** in a single project through an SPV, and **direct ownership** of land or buildings. Earlier stages, such as securing land and power, carry more risk and need specialist diligence.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/invest-in-data-centers-europe/

## Key facts

- Germany’s Data Center Capital offers co-investment tickets of €25 million to €104 million in its projects (company website).
- Storm Group has pre-marketed a Luxembourg fund for buy-and-permit-ready European data center sites, with a regulated Luxembourg AIFM (Storm Group).

_Routes into European data centers_

| Route | Typical access | Liquidity | Main risk |
|---|---|---|---|
| Listed REITs and operators | Any investor | Daily | Market prices |
| Private infrastructure funds | Professional investors, high minimums | Low (fund life) | Manager, leverage |
| Co-investment / club deal (SPV) | Professional or eligible investors | Low (project life) | Single-project concentration |
| Direct land or buildings | Owners and developers | Very low | Power, permits, leasing |

## Questions to ask before investing in a site

- Is the power secured (permit or offer), or only published?
- Can the permit transfer to the end use?
- What is the fallback value if permits fail?
- Who operates the finished data center, and who are the tenants?

## Questions

### Is this investment advice?

No. This page explains how the market is structured. Investing in early-stage real estate and infrastructure can lose money.

# How much land does a data center need per MW?

> Recent European deals imply roughly **550 to 770 m² of land per MW** for multi-storey data centers: about 22,000 m² for 40 MW in Madrid, 17,650 m² for 25 MW near Madrid, and 23,000 m² for about 30 MW near Milan. Single-storey or campus layouts need more.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/land-per-mw-data-center/

## Key facts

- Vicálvaro, Madrid: about 22,000 m² for 40 MW → ≈550 m² per MW (DCD).
- Meco, Madrid: 17,650 m² for 25 MW → ≈706 m² per MW (ActivumSG).
- Milan area (Magnora): 23,000 m² for about 30 MW → ≈767 m² per MW (DCD).
- Ratios are Ampervia’s division of the published figures.

_Land per MW implied by published deals_

| Site | Land | Power | m² per MW |
|---|---|---|---|
| Vicálvaro, Madrid | ≈22,000 m² | 40 MW | ≈550 |
| Meco, Madrid | 17,650 m² | 25 MW | ≈706 |
| Milan area | 23,000 m² | ≈30 MW | ≈767 |

## What else the land must hold

- Substation or switchgear compound and transformer bays.
- Backup generators and fuel.
- Cooling plant, setbacks and access roads.
- Room for a second phase.

## A quick sizing rule

For a 10 MW site, the published deals point to roughly 0.55–0.8 hectares; for 20 MW, about 1.1–1.5 hectares. Planning limits on height and coverage can push this up.

## Questions

### Does a 1-hectare plot fit a data center?

On the ratios above, about 13–18 MW in a multi-storey building, if the power and planning allow it.

# How much grid capacity have data centers requested in Lombardy?

> **44.96 GW** as of 31 July 2026, or 47% of the 95.86 GW requested for data centers across Italy, according to Terna data reported by Key4biz. That compares with a national peak demand of about 58 GW in 2026, so most requests will never be built.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/lombardy-data-center-grid-requests/

## Key facts

- Lombardy data center connection requests: 44.96 GW (31 July 2026).
- Italy total: 95.86 GW requested.
- Italian peak demand 2026: around 58 GW.

## What it means for site value

Requests are reservations, not commitments. The number signals intense competition around Milan, and that sites with an accepted connection solution are worth far more than sites with a request in the queue.

# How much does industrial land cost in Madrid for a data center?

> Along the A-2 Henares corridor, reported industrial land prices in mid-2026 were about **€500/m² in Coslada**, €400–450 in San Fernando de Henares, about €300 in Torrejón de Ardoz and €225–250 in Alcalá de Henares. Prices have risen 25–40% since the pandemic, with data centers and logistics competing for scarce plots.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/madrid-industrial-land-price/

## Key facts

- Coslada: around €500/m², with availability nearly exhausted (El Debate, June 2026).
- San Fernando de Henares: €400–450/m².
- Torrejón de Ardoz: about €300/m² (El Debate); ABC reports €400–450 for San Fernando and Torrejón together.
- Alcalá de Henares: €225–250/m².
- Southern Madrid, Villaverde: €450–500/m² (ABC).
- Industrial land is up 25–40% since the pandemic (ABC, June 2026).

_Reported industrial land prices, Madrid region, June 2026_

| Area | €/m² | Source |
|---|---|---|
| Coslada | ≈500 | El Debate |
| San Fernando de Henares | 400–450 | El Debate |
| Torrejón de Ardoz | ≈300 (El Debate) · 400–450 (ABC) | El Debate, ABC |
| Alcalá de Henares | 225–250 | El Debate |
| Villaverde | 450–500 | ABC |

## Land is the small part of the cost

At €300–500/m² and roughly 550–770 m² per MW, land works out at about €165,000–385,000 per MW before power. A secured connection is what multiplies the value: compare the €11 million paid for a 25 MW site in Meco.

## Power is the constraint in Madrid

In the CNMC’s August 2026 data, 95 of Madrid’s 587 distribution nodes publish any demand capacity and only 9 offer 20 MW or more; no Red Eléctrica transmission node in the province shows demand capacity. See [Madrid grid capacity](https://ampervia.com/data/spain-grid/madrid/).

## Questions

### Is cheaper land further out better?

Only if the power is there. A cheap plot without capacity at a nearby node is industrial land, not a data center site.

# How much does powered land cost per MW in Europe?

> Reported prices run from about **€200,000 to €2.26 million per MW** depending on market and how firm the power is. Prime FLAP-D hubs are at the top (€2.26 million per MW in 2026, per JLL); completed southern European deals have been far lower, such as €11 million for a 25 MW site near Madrid.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/powered-land-price-per-mw-europe/

## Key facts

- €2.26 million per MW: prime FLAP-D powered land, 2026 (JLL).
- €978,000 and €512,000 per MW: secondary and tertiary market averages (Noah Intelligence).
- €11 million for 17,650 m² with a 25 MW power agreement in Meco, Madrid, sold to Pure DC (ActivumSG).
- About 22,000 m² in Vicálvaro, Madrid, sold as powered land to DAMAC’s Edgnex for a 40 MW data center; price not disclosed (DCD).
- A Spanish developer agreed non-binding terms with Pure DC of €1.5 million per site upfront, €1.5 million more at ready-to-build, and €325,000 per MW of leased IT capacity (BeBeez).

_Published Iberian powered-land and site deals_

| Deal | Size | Power | Price |
|---|---|---|---|
| Meco, Madrid → Pure DC (2024) | 17,650 m² | 25 MW | €11 million |
| Vicálvaro, Madrid → Edgnex | ≈22,000 m² | 40 MW | Not disclosed |
| Spanish sites → Pure DC (non-binding) | Per site | — | €1.5m upfront + €1.5m at RTB + €325k per leased MW |

## What moves the price

- **Firmness of power:** an energised or permitted connection is worth several times a capacity that is only published.
- **Market:** primary hubs command a premium for latency and ecosystem.
- **Timing:** late power (years away) is discounted heavily.
- **Transferability:** rules like Spain’s CNAE lock can stop a permit following the land.

## Questions

### Is the price per IT MW or grid MW?

Usually per IT MW in market reports, but deal announcements often quote grid MW. Check before comparing.

### Why are Spanish prices lower than Frankfurt’s?

Lower land values, a younger market and more grid capacity outside Madrid. The gap narrows where power is scarce.

# What is a ready-to-build (RTB) data center site?

> A ready-to-build site has the three things an operator needs to start construction: **land control, a grid connection offer or permit, and planning permits**. It is usually the step where a site’s value jumps, because the slow, uncertain work is done. Deals are often priced in stages tied to reaching RTB.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/ready-to-build-data-center-site/

## Key facts

- Example of staged pricing: non-binding terms between a Spanish developer and Pure DC of €1.5 million per site upfront, €1.5 million at RTB and €325,000 per MW of leased IT capacity (BeBeez).
- A powered site near Madrid (25 MW power agreement) sold for €11 million (ActivumSG).

_From land to ready-to-build_

| Stage | What exists | Main risk left |
|---|---|---|
| Candidate land | A plot near grid infrastructure | No right to power |
| Land under option | Exclusive right to buy | Power and permits |
| Connection secured | Permit or connection offer | Planning |
| Ready-to-build | Land, power and permits | Construction and leasing |

## What a buyer checks at RTB

- The connection offer: capacity, date, works, cost, and whether it transfers.
- Planning permit and conditions.
- Title, easements and contamination.
- Water, fibre and access.

## Questions

### Who buys RTB sites?

Data center operators and developers who want to skip the origination stage, and infrastructure investors building platforms.

# Can an old industrial site’s grid connection be reused for a data center?

> It depends on the country. In **Spain**, no longer by default: since RDL 7/2026 a demand permit is tied to the activity code it was granted for, and changing activity counts as a new installation. The land is still useful, but the data center needs its own request. Elsewhere, reuse is decided case by case with the operator.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/reuse-industrial-site-grid-connection/

## Key facts

- Spain, RDL 7/2026: demand permits must state a CNAE activity code; the connected site must keep that activity for three years or the permit lapses automatically (BOE).
- Holders of existing permits had six months from the decree’s entry into force to update them, or the permits lapse (BOE).
- Italy, DL 21/2026: a single procedure covers a data center and its grid connection, and a temporary medium-voltage connection is accepted in the project documentation (art. 8).
- Lombardy, LR 11/2026: lower construction charges for data centers on brownfield land, higher ones on agricultural land.

_Reusing an industrial grid connection, by country (as of October 2026)_

| Country | Can the plant’s connection carry a data center? | Basis |
|---|---|---|
| Spain | Not automatically: new activity = new installation; file a data center request | RDL 7/2026 |
| Italy | Not settled in law; brownfield is favoured, connection via the single procedure | DL 21/2026, LR 11/2026 (Lombardy) |
| Germany, Netherlands, Ireland, UK | Case by case with the operator; large new loads face allocation rules | See FLAP-D thresholds |

## What still makes old industrial sites valuable

- Industrial zoning and existing access.
- Proximity to substations and high-voltage lines.
- Brownfield incentives in some regions.
- A fallback value as industrial land if a data center permit fails.

## Questions

### Does the three-year rule apply to every request in Spain?

The decree carves out requests tied to urban plans and industrial estates where the infrastructure is ceded to the grid operator. Check the specific case with counsel.

### What happened to permits granted before March 2026?

Their holders had six months to declare the activity code; permits not updated lapse automatically.

# How do data center developers secure power before buying land?

> They tie up the land without buying it, usually with an **option or a purchase conditional on the grid answer**, then file the connection request. Only once capacity is confirmed do they complete the purchase. This keeps the early spend to studies, fees and option premiums.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/secure-power-before-buying-land/

## Key facts

- In Spain, a demand access permit must now name the activity code it will serve, so the request has to be filed for a data center from the start (BOE, RDL 7/2026).
- Italy’s DL 21/2026 lets a project be authorised with a temporary medium-voltage connection while the definitive one is built (art. 8).

## The usual sequence

- Screen nodes with published capacity.
- Option the land (or sign a conditional purchase).
- File the access and connection request.
- Receive the connection offer; pay any reservation guarantee.
- Exercise the option and seek planning.

## Why banks rarely fund this stage

Lenders secure loans on land value. Studies, grid fees and permit work have no collateral until the connection is granted, so this stage is funded with equity, seller options or staged payments from a buyer.

## Questions

### What if the grid answer is no?

With an option, the developer walks away having lost the premium and study costs, not the land price.

# How do small data centers still get power in FLAP-D cities?

> Mostly by staying under the size where scarce-capacity rules start, buying sites that already hold capacity, moving just outside the constrained grid, or bringing their own power. Thresholds are low: **3.5 MW** in Frankfurt (1 MW in local bottlenecks), **3.5 MVA** in Berlin, **5 MVA and 2,000 m²** in Amsterdam, **1 MVA** in Dublin.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/small-data-center-power-flap-d/

## Key facts

- Frankfurt (NRM): new requests of 3.5 MW or more are allocated pro rata; in local bottlenecks from above 1 MW (ingenieur.de).
- Berlin: from 3.5 MVA, capacity is shared out once a year; 70 requests for about 2,300 MVA met 365 MVA available, 47 qualified and 37 received capacity (ingenieur.de).
- Amsterdam: zoning restricts data centers above 2,000 m² floor area and 5 MVA connection capacity (Gemeenteblad 2026-433374).
- Dublin: below 1 MVA a site is exempt from the CRU data centre decision; 1–10 MVA sites must provide an autoproducer unit covering 100% of MIC (Mason Hayes & Curran).
- Germany’s Data Center Capital launched with eight sites of 2–9.5 MW, 46 MW in total, all in southern German cities (IDCNova).

## The six routes

- **Stay under the threshold** (edge and enterprise sites of 1–3.5 MW).
- **Buy a site that already holds capacity**, such as an existing building or older data center.
- **Use approvals granted before the rules tightened.**
- **Move just outside the constrained grid area.**
- **Own or nearby generation** (required in Dublin for 1–10 MVA).
- **Accept a non-firm connection** where offered.

## Questions

### Is there a ban on data centers in these cities?

Not a general ban. Capacity is rationed, and Amsterdam limits size by zoning.

### Why are secondary German cities attractive?

Smaller loads fit local grids; Data Center Capital’s launch portfolio of sub-10 MW sites shows the model.

# Where is grid capacity available for data centers in Spain?

> Capacity exists, but rarely where data centers queue. In the CNMC’s August 2026 data, **816 of 6,186** Spanish distribution nodes publish any demand capacity, and only **104** offer 20 MW or more. Madrid has 9 such nodes and no transmission node with demand capacity, while provinces such as Lugo, Murcia and Asturias publish far more.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/spain-grid-capacity-data-centers/

## Key facts

- 816 of 6,186 distribution nodes publish demand capacity; 200 offer ≥10 MW and 104 offer ≥20 MW (CNMC, August 2026; Ampervia aggregation).
- Open distribution nodes fell from 862 in June to 816 in August 2026.
- 290 of 937 Red Eléctrica transmission nodes show demand capacity in at least one published category; none of Madrid’s 91 do.
- About 12 GW of grid access has been granted to data centers in Spain: more than 6 GW on transmission since end-2023 and around 6 GW on distribution since 2020, against a 2030 demand forecast of 3.5–4 GW (Yeandel, citing official figures).

## Where to look

The province table at [Spain grid capacity by province](https://ampervia.com/data/spain-grid/) ranks all provinces by published demand capacity, with the number of nodes at 10 and 20 MW and the change since June.

## Why granted capacity does not mean free capacity

Much of the ~12 GW already granted sits with projects that may never be built. RDL 7/2026 now ties each permit to a declared activity and adds a capacity-reservation charge payable from the permit until activity starts, which should push unused permits back to the grid over time.

## Questions

### Is published capacity a connection offer?

No. It shows where a request can be filed. Only the operator’s study confirms capacity for a specific project.

### Why is Madrid so constrained?

Data center demand has concentrated there for years; the transmission nodes around the city show no demand capacity in the latest CNMC data.

# What is powered land, and why is it worth more?

> Powered land is land that already has a grid connection, or a secured right to one, big enough for a data center. Because grid capacity, not land, is the scarce input, it is priced per megawatt: JLL puts prime powered land in Europe’s core hubs at about **€2.26 million per MW** in 2026, up 82% from €1.24 million in 2021.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/answers/what-is-powered-land/

## Key facts

- Prime powered land in FLAP-D hubs: about **€2.26 million per MW** in 2026, up from €1.24 million in 2021 (+82%) — JLL.
- Reported averages outside the core: about **€978,000 per MW** in secondary markets and **€512,000 per MW** in tertiary markets — Noah Intelligence, citing the same price series.
- BSIC puts core markets at €800,000–€1.4 million per MW and sites where power arrives late at €200,000–€700,000 per MW.
- A completed Madrid sale: 17,650 m² in Meco with a 25 MW power agreement sold to Pure DC for **€11 million** (about €440,000 per MW) — ActivumSG.

_Reported powered-land prices in Europe, per MW_

| Market tier | Price per MW | Source |
|---|---|---|
| Prime FLAP-D hubs (2026) | €2.26 million | JLL |
| Prime FLAP-D hubs (2021) | €1.24 million | JLL |
| Secondary markets | €978,000 | Noah Intelligence |
| Tertiary markets | €512,000 | Noah Intelligence |
| Core markets (range) | €0.8–1.4 million | BSIC |
| Late-arriving power (range) | €0.2–0.7 million | BSIC |
| Meco, Madrid, 25 MW (completed sale, 2024) | ≈€440,000 | ActivumSG |

## Levels of power readiness

- **Near a substation:** no right to capacity yet. Not powered land.
- **Capacity published at the node:** a request can be filed, but nothing is reserved.
- **Access permit or connection offer:** capacity reserved for the site. This is what buyers pay for.
- **Energised connection:** power can be drawn now.

## Why it is priced per MW

A data center’s revenue scales with the IT megawatts it can run, and grid queues in core markets run for years. A buyer therefore compares sites by what each megawatt of secured capacity costs, not by area.

## Watch-outs

- Ask for the permit or connection offer, not a description of nearby infrastructure.
- Check whether the right can transfer to a new owner and a new activity. In Spain it may not: see [RDL 7/2026](https://ampervia.com/rules/spain-rdl-7-2026-data-centers/).
- Grid MW and IT MW differ. Check which one a price refers to.

## Questions

### Is land near a substation powered land?

No. Without a permit or connection offer, the land has no right to capacity. It is a candidate, priced as industrial land.

### Can powered land lose its power?

Yes. Permits can lapse if milestones are missed, and in Spain a demand permit lapses if the connected site does not keep its declared activity for three years.

# FLAP-D grid connection thresholds for data centers

> In Europe’s core markets, rationing starts at small sizes: **3.5 MW** in Frankfurt (above 1 MW in local bottlenecks), **3.5 MVA** in Berlin, **5 MVA** with a 2,000 m² floor cap in Amsterdam, about **40 MW** before a Paris-area project moves from Enedis to RTE, **1 MVA** in Dublin, and multi-year waits above 1 MVA in West London.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/rules/flap-d-grid-connection-thresholds/

## Key facts

- Ireland: data centres at or above 1 MVA must show a credible plan to meet at least 80% of annual demand from new Irish renewable generation, within a six-year glide path (Mason Hayes & Curran).
- Berlin’s first allocation: about 2,300 MVA requested against 365 MVA available (ingenieur.de).

_Where connection rules change, by city_

| City | Threshold | What happens above it | Source |
|---|---|---|---|
| Frankfurt | 3.5 MW (1 MW in bottlenecks) | Pro-rata allocation of new requests by NRM | ingenieur.de |
| Berlin | 3.5 MVA | Annual allocation; 37 of 70 requests got capacity in the first round | ingenieur.de, Raue |
| Amsterdam | 5 MVA and 2,000 m² | Zoning restricts new or expanded data centers | Gemeenteblad 2026-433374 |
| Paris region | ≈40 MW | Connection moves from Enedis distribution to RTE transmission | Grid Readiness |
| Dublin | 1 MVA | CRU rules: 1–10 MVA needs an autoproducer covering 100% of MIC | Mason Hayes & Curran |
| West London | 1 MVA | Multi-year waits, some connection dates toward 2035 | Data Centre Axis |

# Ireland’s data centre grid connection rules

> Ireland’s energy regulator (CRU) decided in December 2025 to tier data centre connections by maximum import capacity. Below **1 MVA** a site is exempt; from 1 to 10 MVA it must provide an **autoproducer unit covering 100% of its MIC**; and sites at or above 1 MVA must show a credible plan to meet at least **80%** of annual demand from new Irish renewable generation within six years.

## Key facts

- Decision published 12 December 2025; initial proposals due 31 March 2026 (Transatlantic Law).
- De minimis: 1 MVA. Tier 2: 1–10 MVA.
- 1–10 MVA: autoproducer unit able to meet 100% of MIC (Mason Hayes & Curran).

# Italy DL 21/2026: the single authorisation for data centers

> Article 8 of Italy’s Decree-Law 21/2026 (converted by Law 49/2026) puts a data center and its grid connection into a **single authorisation procedure**, and allows a **temporary medium-voltage connection** in the project documentation, with a definitive solution added later. It speeds up permitting; it does not create grid capacity.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/rules/italy-dl-21-2026-data-centers/

## Key facts

- Legal basis: DL 21/2026, art. 8, converted by L. 49/2026.
- A temporary medium-voltage connection solution is accepted, with an obligation to integrate the definitive solution (art. 8, para. 1-bis).
- Lombardy acts as competent authority in the single procedure for projects in the region (LR 11/2026).

## What it means for a site

Permitting and connection run in one track, which shortens time to ready-to-build. Capacity still has to be secured from Terna or the distributor, and Lombardy alone has 44.96 GW of data center requests queued.

# Lombardy Regional Law 11/2026: data centers on brownfield land

> Lombardy’s Regional Law 11/2026 is Italy’s first regional framework for data centers. It rewards building on **brownfield** land (construction charges cut by 10–30%, set by each municipality) and penalises farmland (charges doubled, tripled in protected areas). Data centers above 5 MW are treated as production facilities.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/rules/lombardy-lr-11-2026-data-centers/

## Key facts

- Approved by the Regional Council on 26 May 2026; published in BURL no. 23 of 5 June 2026 (Studio Inzaghi).
- Brownfield: construction charges reduced by 10–30%, as each municipality decides (Studio Inzaghi; HLC: up to 30%).
- Agricultural land: +100% surcharge; +200% in regional parks or areas of environmental significance (HLC).
- Data centers above 5 MW are classed as production facilities; up to 5 MW can be compatible with tertiary or office zoning (Osborne Clarke).
- Municipalities must map disused, contaminated and degraded areas within a year (BibLus).
- Key4biz reports the incentive regime operating from 28 August 2026 under implementing resolutions 6645 and 6646.

_Construction charges under LR 11/2026_

| Land type | Effect on construction charges |
|---|---|
| Brownfield (disused, contaminated, degraded) | −10% to −30% |
| Agricultural land | +100% |
| Regional parks / environmentally significant areas | +200% |

## What it does not do

The law does not allocate grid capacity. Sites still need a connection from Terna or the distributor.

# Spain RDL 7/2026: what it changes for data center grid access

> Real Decreto-ley 7/2026 of 20 March 2026 requires every demand access and connection permit to state the **CNAE activity code** it will serve. The connected site must keep that activity for **three years** or the permit lapses automatically, and existing permit holders had **six months** to declare their code. For data centers, the request has to be filed as a data center from the start.

By Razvan Toma, Founder & CEO, Ampervia · Last checked 2026-10-12 · https://ampervia.com/rules/spain-rdl-7-2026-data-centers/

## Key facts

- Instrument: Real Decreto-ley 7/2026, de 20 de marzo (BOE-A-2026-6544).
- Demand permits must specify the CNAE code of the activity; the permit is lost if the real activity does not match.
- The connected installation must keep the same activity for three years; otherwise the permit lapses automatically.
- Holders of permits already granted had six months from entry into force to update them; permits not updated lapse automatically.
- The decree’s preamble notes that access permits already granted to data centers exceed the most ambitious deployment estimates several times over.

## What it means in practice

- A factory’s permit cannot simply be reused for a data center: a new activity needs its own request.
- Speculative permits become costlier to hold, which should free capacity over time.
- Due diligence on any Spanish powered-land sale must check the permit’s declared code.

## Open questions

How the rule applies to long-standing access contracts and to requests tied to urban plans or industrial estates should be checked with counsel for each site.

## Questions

### Does RDL 7/2026 ban data centers?

No. It ties grid permits to real projects and their declared activity.

### Where can I see published capacity?

Ampervia aggregates the CNMC data by province at [Spain grid capacity by province](https://ampervia.com/data/spain-grid/).

# About Ampervia and Razvan Toma

Ampervia Capital is a data center infrastructure capital company focused on Europe. Its founder, Razvan Toma, writes and speaks on powered land and grid access for data centers in southern Europe.

What Ampervia does
Ampervia finds sites where land and grid capacity line up, secures them with its members through one vehicle per site, takes them to
ready-to-build, and brings institutional capital in for the build. Its public research product is the Ampervia
Powered-Land Map; the answers, rules tracker and datasets on this site publish the research behind it.


Razvan Toma, founder and CEO
Razvan Toma leads Ampervia’s site origination and research: reading grid capacity node by node, the rules that govern connections
in each country, and the economics of taking a site from land to ready-to-build. He is available to journalists and conference organisers
on these topics:


- Powered land
- Data center grid access in Spain and Italy
- Ready-to-build data center sites
- Data center site origination
- European data center investment

Follow or contact him on [LinkedIn](https://www.linkedin.com/in/razvantoma/), or write to
[team@ampervia.com](mailto:team@ampervia.com).


How we source
- Every figure links to its source, with the date we last checked it.

- Our own datasets, such as [Spain grid capacity by province](https://ampervia.com/data/spain-grid/), are built from official publications and refreshed monthly.

- We publish aggregates only and never identify a candidate site, its owner or its municipality. Site-level research is for Club members.

- Nothing here is investment advice or an offer of any security.


---

# The Ampervia Club: the deal room for data center sites

> The Ampervia Club is a $25,000-a-year membership and private deal room for qualified investors. Members see every data center site Ampervia works on, with the grid, permit and land evidence behind it, and choose site by site whether to co-invest in the vehicle that takes it to ready-to-build. Membership is not itself an investment and carries no obligation to invest.

## The deal room

- Every site Ampervia is working on, identified, not redacted
- The evidence file: grid capacity, connection route, land, permits, comparable sales
- First right to join each site vehicle, before anyone outside the Club
- Updates as each site moves from option to ready-to-build

## The people and the research

- Quarterly member calls on the pipeline and the market
- Country notes on grid rules and permits as they change
- Introductions to operators, developers and lenders we work with
- Full access to Ampervia’s research and the Powered-Land Map data

## How a deal runs

1. **Deal room** — Ampervia finds and screens sites where land and grid capacity line up. Members see them with the full evidence.
2. **Site vehicle** — When a site is worth securing, Ampervia forms a vehicle (SPV) for it. Members decide whether to join; land is first held under option where possible.
3. **Ready-to-build** — The vehicle buys the land and takes the site to ready-to-build: land, connection offer, permits. If permits stall, it still owns industrial land.
4. **Sell or continue** — The ready site is sold, or carried into the build. Each member of that vehicle chooses: take their share, or continue.
5. **Build** — Infrastructure funds, family offices, operators and banks fund construction. Continuing members move into the build vehicle with the new capital.

## Membership

$25,000 per year. Membership is a paid information and research service. It is not an investment, does not buy an interest in any site, and carries no obligation to invest. Each site vehicle has its own documents, terms and costs, shared with eligible members before they decide.

**Important.** This website is for information only. It is not an offer to sell or a solicitation to buy any security or interest in any fund or vehicle, and nothing on it is investment advice. Club membership is a paid information and research service and is not itself an investment. Any participation in a site vehicle is offered privately, only to eligible investors, under that vehicle’s own documents. Sites shown are research inventory, not secured projects. Investing in early-stage real estate and infrastructure carries a risk of loss.

# Spain grid capacity for data centers, by province

> **816 of 6,186** Spanish distribution nodes publish any available demand capacity in the CNMC’s August 2026 data, and only **104** offer 20 MW or more, the size a small data center needs. Open nodes fell from 862 in June 2026. Province table below, updated monthly.

Ampervia · Last checked 2026-10-12 · https://ampervia.com/data/spain-grid/

- **6,186** — distribution nodes
- **816** — publish demand capacity
- **104** — offer 20 MW or more
- **290 / 937** — transmission nodes with capacity

## Findings

- **Only 104 nodes offer 20 MW or more** Of 6,186 distribution nodes, 200 publish 10 MW or more and 104 publish 20 MW or more of demand capacity (August 2026).
- **Open nodes fell by 46 in two months** 862 nodes published capacity in June 2026; 816 in August 2026.
- **Madrid: 95 of 587 nodes open** Only 9 Madrid nodes offer 20 MW or more, and none of its 91 Red Eléctrica transmission nodes shows demand capacity.
- **Published capacity is not a connection offer** It shows where a request can be filed. Only the operator’s study confirms capacity for a specific project.

## Method

Source: the CNMC’s national access-capacity service, layers _Demanda en Distribución_ and _Demanda en Transporte_,
publication period August 2026, pulled by Ampervia on 2026-10-12. Comparison period: June 2026.


- **Distribution:** each node’s published _available capacity_ (CAP_DISPONIBLE, MW) for new demand, summed and counted by province.

- **Transmission:** a Red Eléctrica node is counted as showing demand capacity if any of its published demand categories is above zero.

- Province names are as published by the CNMC. Ampervia does not publish node or municipality detail.

- Published capacity is indicative and changes as permits are granted, lapse or are surrendered. Only the network operator can confirm capacity for a specific request.

### What does available demand capacity mean?

The access capacity for new consumption each distributor publishes per node under Spain’s capacity-transparency rules, compiled in the CNMC’s national map.

### Can I get the figure for a single substation?

The CNMC publishes node-level data on its own map. Ampervia publishes province totals only and does not identify individual sites.

### How often is this updated?

Monthly, after the CNMC publishes a new period. This edition uses period August 2026, pulled on 2026-10-12.

## What this means for a data center

No distribution node in Albacete publishes 10 MW or more of demand capacity. A data center here would need a transmission-level connection, grid reinforcement or a much smaller load.

Since March 2026, a Spanish demand access permit is tied to the CNAE activity code declared in the request ([RDL 7/2026](https://ampervia.com/rules/spain-rdl-7-2026-data-centers/)), so the request has to be filed as a data center from the start.

## What this means for a data center

No distribution node in Badajoz publishes 10 MW or more of demand capacity. A data center here would need a transmission-level connection, grid reinforcement or a much smaller load.

Since March 2026, a Spanish demand access permit is tied to the CNAE activity code declared in the request ([RDL 7/2026](https://ampervia.com/rules/spain-rdl-7-2026-data-centers/)), so the request has to be filed as a data center from the start.

## Method

publication period August 2026, pulled by Ampervia on 2026-10-12. Comparison period: June 2026.


- **Distribution:** each node’s published _available capacity_ (CAP_DISPONIBLE, MW) for new demand, summed and counted by province.

- **Transmission:** a Red Eléctrica node is counted as showing demand capacity if any of its published demand categories is above zero.

- Province names are as published by the CNMC. Ampervia does not publish node or municipality detail.

- Published capacity is indicative and changes as permits are granted, lapse or are surrendered. Only the network operator can confirm capacity for a specific request.

## What this means for a data center

No distribution node in Ciudad Real publishes 10 MW or more of demand capacity. A data center here would need a transmission-level connection, grid reinforcement or a much smaller load.

Since March 2026, a Spanish demand access permit is tied to the CNAE activity code declared in the request ([RDL 7/2026](https://ampervia.com/rules/spain-rdl-7-2026-data-centers/)), so the request has to be filed as a data center from the start.

## Method

Source: the CNMC’s national access-capacity service, layers _Demanda en Distribución_ and _Demanda en Transporte_,
publication period August 2026, pulled by Ampervia on 2026-10-12. Comparison period: June 2026.


- **Distribution:** each node’s published _available capacity_ (CAP_DISPONIBLE, MW) for new demand, summed and counted by province.

- **Transmission:** a Red Eléctrica node is counted as showing demand capacity if any of its published demand categories is above zero.

- Province names are as published by the CNMC. Ampervia does not publish node or municipality detail.

- Published capacity is indicative and changes as permits are granted, lapse or are surrendered. Only the network operator can confirm capacity for a specific request.

Since March 2026, a Spanish demand access permit is tied to the CNAE activity code declared in the request ([RDL 7/2026](https://ampervia.com/rules/spain-rdl-7-2026-data-centers/)), so the request has to be filed as a data center from the start.

## Method

Source: the CNMC’s national access-capacity service, layers _Demanda en Distribución_ and _Demanda en Transporte_,
publication period August 2026, pulled by Ampervia on 2026-10-12. Comparison period: June 2026.


- **Distribution:** each node’s published _available capacity_ (CAP_DISPONIBLE, MW) for new demand, summed and counted by province.

- **Transmission:** a Red Eléctrica node is counted as showing demand capacity if any of its published demand categories is above zero.

- Province names are as published by the CNMC. Ampervia does not publish node or municipality detail.

- Published capacity is indicative and changes as permits are granted, lapse or are surrendered. Only the network operator can confirm capacity for a specific request.

Since March 2026, a Spanish demand access permit is tied to the CNAE activity code declared in the request ([RDL 7/2026](https://ampervia.com/rules/spain-rdl-7-2026-data-centers/)), so the request has to be filed as a data center from the start.

## Method

publication period August 2026, pulled by Ampervia on 2026-10-12. Comparison period: June 2026.


- **Distribution:** each node’s published _available capacity_ (CAP_DISPONIBLE, MW) for new demand, summed and counted by province.

- **Transmission:** a Red Eléctrica node is counted as showing demand capacity if any of its published demand categories is above zero.

- Province names are as published by the CNMC. Ampervia does not publish node or municipality detail.

- Published capacity is indicative and changes as permits are granted, lapse or are surrendered. Only the network operator can confirm capacity for a specific request.

# Glossary of data center, grid and powered-land terms

**Access and connection permit** — In Spain, the _permiso de acceso y conexión_: the operator’s grant of the right to connect a given load at a given node. Since RDL 7/2026 it carries a CNAE activity code.

**Access capacity** — The capacity, in MW, a network operator publishes as available at a node for new consumers (demand) or new plants (generation). In Spain it is published per node and compiled by the CNMC. See [Spain grid capacity by province](https://ampervia.com/data/spain-grid/).

**AI factory** — Industry term for data centers built for AI training and inference, with much higher power density per rack than traditional facilities.

**AIFM** — Alternative investment fund manager, the regulated manager required under EU rules when capital is pooled from investors into a fund.

**Autoproducer unit** — In Irish rules, on-site or nearby dispatchable generation a data center must provide to cover its demand; required at 100% of MIC for sites of 1–10 MVA.

**Behind-the-meter power** — Generation on the consumer’s side of the grid meter (on-site gas, solar, batteries) supplying the data center directly.

**Brownfield site** — Previously developed land, often a closed factory. In Lombardy, brownfield data centers get lower construction charges than greenfield ones.

**Capacity reservation guarantee** — A deposit or periodic charge a developer pays to hold grid capacity before using it. Spain’s RDL 7/2026 created one for demand permits of 1 kV and above, payable until activity starts.

**Capex per MW** — Construction cost divided by IT capacity, the standard way to compare data center build costs.

**Club deal** — A transaction in which a small group of investors invest together, usually through an SPV, instead of through a blind-pool fund.

**CNAE code** — Spain’s classification of economic activities. Under RDL 7/2026 a demand permit states the CNAE code of the activity it will serve, and the permit lapses if the connected site does not keep that activity for three years.

**CNAE lock** — Shorthand for the RDL 7/2026 rule tying a Spanish demand permit to its declared activity code, which stops a factory’s permit being reused for a data center.

**Co-investment** — Investing directly in a specific deal alongside a sponsor or fund, usually on the same terms.

**Colocation** — A data center that leases space, power and cooling to several customers.

**Connection offer** — The operator’s formal offer setting the capacity, works, cost and date of a connection. The strongest evidence that a site is powered.

**Connection queue** — The list of pending connection requests an operator processes. Queue position, not land, often decides when a site can energise.

**Distribution grid** — The lower-voltage network run by distribution operators (in Spain, distributors such as i-DE, e-distribución or UFD). Most connections of a few to a few tens of MW sit here.

**DSO** — Distribution system operator: the company running the local lower-voltage grid.

**Edge data center** — A small facility, often under 5 MW, placed close to users for low latency.

**Energisation** — The moment a connection is switched on and the site can draw power.

**Firm connection** — A connection with guaranteed capacity at all times.

**FLAP-D** — Frankfurt, London, Amsterdam, Paris and Dublin, Europe’s five primary data center markets, all power-constrained. See [FLAP-D connection thresholds](https://ampervia.com/rules/flap-d-grid-connection-thresholds/).

**GDV** — Gross development value: the expected value of a project once built and let.

**Greenfield site** — Land never developed before, typically agricultural.

**Grid capacity (site)** — The total power a site may draw from the grid, including cooling and losses. Higher than the IT load; the ratio depends on PUE.

**Hyperscale** — Very large data centers built by or for the biggest cloud providers, usually tens to hundreds of MW per campus.

**IT load** — The power drawn by the servers and network equipment, excluding cooling and losses. Data center capacity and prices per MW usually refer to IT MW.

**Land option** — A contract giving the right, not the obligation, to buy land at an agreed price within a period, so a developer can secure power and permits before buying.

**MIC** — Maximum import capacity: in Ireland, the contracted maximum a site may draw from the grid. Irish data center rules are tiered by MIC.

**MVA** — Megavolt-ampere, the unit of apparent power used for connection sizes. Close to MW for planning purposes; connection rules in Berlin, Amsterdam, Dublin and London are set in MVA.

**Node** — A point on the grid, usually a substation busbar at one voltage, where capacity is published and new connections are made.

**Non-firm (flexible) connection** — A connection the operator may curtail at times of grid stress, offered sooner than a firm connection. Used in Germany, the UK and Ireland to connect loads earlier.

**Powered land** — Land with a grid connection, or a secured right to one, large enough for a data center. Its price is driven by the megawatts it can draw, so it is usually quoted per MW rather than per square metre. See [What is powered land?](https://ampervia.com/answers/what-is-powered-land/)

**Powered shell** — A building with power delivered to it but without the tenant’s fit-out (cooling, racks, internal electrical). A step after powered land.

**Pro-rata allocation** — Sharing scarce capacity among applicants in proportion to their requests, instead of first come, first served. Used by Frankfurt’s and Berlin’s grid operators.

**PUE** — Power usage effectiveness: total facility energy divided by IT energy. A PUE of 1.3 means 30% on top of the IT load.

**Ready-to-build (RTB)** — A data center site with land control, a grid connection offer or permit, and the planning permits needed to start construction. See [What is a ready-to-build site?](https://ampervia.com/answers/ready-to-build-data-center-site/)

**Shovel-ready** — Informal synonym for ready-to-build: construction could begin without further permits.

**Single authorisation (Italy)** — The single procedure introduced by Italy’s Decree-Law 21/2026, article 8, covering a data center and its grid connection in one authorisation.

**SPV** — Special purpose vehicle: a company formed to hold one project, so its investors, debt and risks stay separate. See [How SPVs and club deals work](https://ampervia.com/answers/data-center-spv-club-deal/).

**Substation** — A facility that transforms voltage between grid levels. Distance to a substation with spare capacity is one of the first site-selection filters.

**Transmission grid** — The high-voltage network run by the transmission system operator (Red Eléctrica in Spain, Terna in Italy, RTE in France). Large campuses connect here.

**TSO** — Transmission system operator: the company running the high-voltage grid of a country or zone.

**Will-serve letter** — A utility’s written statement that it can supply a site. Common in the US; in Europe the equivalent evidence is a connection offer or permit.
