Segovia Data Center 2026: What It Means for UK Buyers

What was actually announced

The project is structured through Ignis Data Epta, a vehicle established in 2024 that until now sat wholly within Ignis P2X — the data centre platform jointly owned by Ignis and private equity firm KKR. Acciona has now acquired a 50 percent stake in Ignis Data Epta, with Ignis retaining the other half, according to DatacenterDynamics.

The deal also covers joint acquisition of the adjacent photovoltaic plant designed to power the facility with renewable energy, while grid access and connection permits — already processed through two Ignis subsidiaries — are now formally shared between both partners.

For Acciona, chaired by José Manuel Entrecanales, Segovia slots into a wider push to reach 2GW of data centre capacity. The activity used to sit inside Acciona's Construction division; it has been run by a dedicated Acciona Data Centers unit for less than two years.

Why the renewables-linked model matters

Acciona points to its recent agreement with Apto for a data centre campus in Fuenlabrada, Madrid, as the template for this approach: 82MW of grid access and connection paired with a long-term power purchase agreement tied to a 94MW solar plant developed by Ignis. Segovia follows the same logic — capacity and clean power procured together, not bolted on afterwards.

For UK buyers evaluating suppliers or colocation partners with sustainability commitments, this bundled generation-plus-compute model is worth watching. It suggests continental developers are increasingly using co-located renewables as a core financing and planning mechanism, not a compliance afterthought — relevant if your organisation is weighing UK compute strategy: on-prem, colocation, or cloud against sustainability targets.

Spain's build-out is broader than one site

Segovia doesn't sit in isolation. Ignis is also involved in DayOne's 300MW data centre project in Aragón, while Valladolid is separately attracting one of Spain's larger data centre proposals, and Ferrovial has outlined a €1 billion Madrid campus with an initial €153 million phase across roughly 32,000 square metres.

SpainDC's industry projection, cited by DCD, puts total direct investment into Spain's data centre sector at around €8 billion through 2026 — context for why multiple developers, not just hyperscalers, are moving simultaneously across Segovia, Madrid, Aragón and Valladolid.

• •Ignis Data Epta JV: Ignis and Acciona each hold 50%
• •Precedent deal: 82MW grid connection + 94MW solar PPA at Fuenlabrada
• •Acciona's stated ambition: 2GW of data centre capacity

What it means for UK data residency and latency planning

More Iberian hyperscale and colocation capacity gives UK enterprises another credible option for diversifying latency-sensitive workloads away from London and the traditional FLAPD hubs. That matters for firms building resilience plans or exploring hyperscale data centre locations and UK resilience strategies that don't rely solely on Frankfurt or Amsterdam.

It's also relevant to data residency planning. Organisations weighing EU-domiciled storage against domestic UK hosting now have a wider set of physically distinct, renewables-backed sites to evaluate, which can support regulatory or contractual requirements around data locality without forcing a single-region dependency.

Pricing pressure UK buyers should factor in

CBRE's outlook, referenced by DCD, expects Europe's data centre market to grow by nearly a quarter in 2026, with colocation demand still strong enough to keep supply tight. FLAPD capacity pricing is separately expected to rise by 12 percent this year — a signal that even as Spain adds capacity, continental pricing pressure is unlikely to ease quickly.

CBRE also expects colocation supply to remain roughly 50 percent larger than self-build capacity at the end of 2026, meaning hyperscalers and enterprises alike are still leaning heavily on third-party space rather than building their own. Long-term leasing remains common in Spain too — Meta has reportedly rented Spanish capacity from Merlin Properties on contracts spanning five to fifteen years — while Equinix's Barcelona BA1 site, at over 1,500 square metres, shows the scale active retail colocation already reaches in the market.

For UK buyers, the practical takeaway is timing: if European demand keeps outpacing supply, locking in domestic or cross-border capacity commitments before further 2026 price rises filter through could be the more cost-effective move. Teams weighing this should calculate your cloud vs on-premise TCO and plan your rack space and power density before negotiating contract terms.

Practical next steps for UK infrastructure teams

Before treating Iberian capacity as a latency or residency hedge, UK buyers should map actual workload requirements against what's genuinely on offer. Not every project announced today will deliver near-term capacity, and grid connection timelines vary by region.

Teams still building a baseline domestic strategy may get more immediate value from guidance on choosing a UK colocation data centre, while those exploring hybrid or multi-region setups can use understand what colocation is as a starting reference before evaluating cross-border options. Financing structures also matter at this scale — reviewing IT financing options early can shape whether a long-term European lease or a domestic build makes more sense.
