Ask any experienced data center developer what determines whether a site works, and the answer rarely starts with the price per acre. It starts with a single question: can this site be energised, at the required capacity, within a timeline the business case can tolerate? In 2026, that question has become harder to answer affirmatively in almost every major market — and the gap between power-secured and power-uncertain land has turned into the defining scarcity of the sector.
The Interconnection Queue Has Become the Real Site Plan
Utilities across Europe and North America are managing project pipelines that have accelerated dramatically, even as not every queued project will ultimately proceed. For data center developers, this means that a site's true delivery timeline is no longer set by permitting or construction — it is set by where that project sits in a utility's interconnection queue, and by the availability of the specific electrical equipment required to energise it.
Generator step-up transformer demand has grown by roughly 274% since 2019, while standard power transformer demand has grown by around 119% over the same period. Average lead times for standard power transformers now run to roughly 128 weeks, with generator step-up units averaging around 144 weeks — and some specialised orders extending considerably further. These are not abstractions for a developer's schedule; they are now the single largest determinant of when a facility can be switched on.
Land Cost Has Become a Rounding Error
Electrical equipment — transformers, switchgear, breakers and batteries — typically represents less than 10% of total data center construction cost, yet it now functions as the binding constraint on the other 90% of capital deployed. A well-located, fully-permitted site with no secured grid capacity is, in practical terms, not a usable site at all. Conversely, land in a less prime location with confirmed, near-term power availability has become significantly more valuable than its raw real estate characteristics would suggest.
- Utility load studies and service agreements are now earlier and more consequential milestones than zoning approval in many jurisdictions
- Substation configuration, spare transformer bay availability, and competing load requests in the same grid node materially affect feasibility
- Developers increasingly pursue parallel paths — grid connection alongside onsite generation — to de-risk single-point dependency on utility timelines
A site without secured power is not undervalued real estate — it is, for practical purposes, not yet a site at all.
What Power-Secured Really Means in Practice
"Power-secured" is frequently used loosely. A rigorous definition requires confirmation across several layers: a signed or near-final interconnection agreement, confirmed transformer and switchgear order positions with credible delivery dates, and a utility-confirmed energisation date that aligns with the project's financing and tenant commitments. Sites that can demonstrate this level of certainty are increasingly able to command premium terms from both equity investors and prospective hyperscale or enterprise tenants.
This has practical implications for how due diligence should be structured. Technical and commercial diligence on a prospective site should treat the interconnection agreement and equipment procurement status as primary documents, equivalent in importance to title and zoning records, rather than as secondary technical appendices reviewed late in the process.
How This Is Reshaping Negotiations Between Developers and Utilities
The scarcity of power-secured land is also changing the negotiating dynamic between developers and utilities. Where utilities once competed for large new industrial loads as a source of guaranteed revenue, many now find themselves managing an oversubscribed queue and can be more selective about which projects receive priority treatment. This has pushed sophisticated developers toward offering utilities greater commitment certainty — non-refundable deposits, take-or-pay arrangements, or co-investment in grid upgrades — in exchange for queue priority or accelerated study timelines.
It has also accelerated interest in alternative arrangements that reduce dependence on the conventional interconnection queue altogether. Direct negotiated agreements for incremental transmission capacity, co-location with existing industrial loads that already have established grid connections, and behind-the-meter generation paired with a smaller, faster-to-secure grid connection are all becoming more common structuring strategies precisely because the traditional path has become so much less predictable.
A Genuine Repricing of Site Value Is Underway
Markets are still in the process of repricing land to reflect this reality. Appraisal methodologies built for an era when land cost and construction cost dominated total project economics have not fully caught up with a world where power availability can be the difference between a project that delivers in three years and one that never delivers at all. Investors and developers who internalise this repricing early — treating confirmed power availability as the primary driver of site value rather than a secondary technical consideration — are likely to identify mispriced opportunities before the broader market catches up.
Implications for Developers and Capital Allocators
For developers, this scarcity argues for engaging utilities and equipment suppliers at the earliest possible stage of site evaluation — often before formal land control is even secured. For capital allocators, it argues for underwriting frameworks that price interconnection and equipment risk explicitly, rather than treating it as a generic construction contingency.
DATAPERT supports clients through exactly this process — combining feasibility studies with grid and equipment risk assessment to identify which sites are genuinely power-secured, and which only appear to be.
