Methods, limitations and revision history

Counting and measurement

Directory listing, building, campus, phase and investment programme are different units. Capacity retains its source’s date and power basis. IT load and total site electricity demand are not interchangeable.

Status

Operating
Evidence of delivered capacity serving workloads, with source interpretation stated.
Under construction
Evidence of on-site works. Initial roads and earthworks do not establish completed data halls.
Proposed
A commitment without confirmed construction.
Delayed, suspended, cancelled
Separate outcomes requiring dated evidence; national totals are not established here.

Costs and sources

Spent capital, commitments, estimates and reported budgets remain distinct. No currency conversions or overlapping totals are calculated. Source checks establish what a publisher says; they do not independently prove a company’s capacity, spending or returns.

Coverage limits

National construction totals, water impacts, whole-life energy costs, subsidies and investment returns remain incomplete. Directory observations are from November 2025. The proprietary capacity dataset was not accessed. This review cannot substantiate a global historical superlative.

V5 changes from Grok V4

V6 support and contribution links

Added voluntary research-support wording, an optional payment reference in contact-form instructions, and links to the contribution format and registry. The published contribution record is now linked. Findings and datasets are unchanged.

Public edition 1

Released 1 November 2026 after John A Brown’s review. Added published registry and XML links. This release preserves the V5 evidence tables and V6 support wording; it does not claim a new national pipeline survey. Contributions remain voluntary and independent of editorial decisions.

If you would like us to associate your suggestion with a contribution, include your PayPal transaction ID or receipt reference, payment date, amount and currency. Providing a payment reference is optional. These details remain private.

Suggestions help guide future research. Contributions do not guarantee that a topic will be undertaken, buy priority or determine our findings. You are also welcome to suggest research without contributing.

Contributions and AI assistance

Research compiled by Grok under instruction from John A Brown, The Blue•Print Research Unit. Editorial integration and source checks used ChatGPT assistance at John’s direction.

The original question and scope came from John. AI assistance produced drafts, tables and website code and helped check cited sources. John approved publication of this edition. Checking cited material is not independent verification of underlying claims.
