Investing In Data Centres: The Rules Change While You’re Building
European Data Centres, Read from the Gulf · Part Four of Seven
Written by Lanre Okunnuga, August 2026
Three claims about AI infrastructure circulate widely enough to pass without argument. The United States has more capital than it can spend. Europe does not have enough capacity. The Gulf has more land and power than it can use.
Alphabet posted its first negative free cash flow since its 2004 IPO. Amazon’s trailing twelve-month figure went negative in the same stretch. Aggregate hyperscaler capital expenditure is on track to overtake operating cash flow around the third quarter of 2026. Satya Nadella has described his own bottleneck as power, with GPUs he cannot yet plug in. American capital is pressing against a physical limit.
Ofgem counted the British connection queue in July 2026 and found around 73 gigawatts of data centre demand across roughly 315 projects. National peak demand on 11 February 2026 was 45 gigawatts. The regulator has proposed charging between £237,500 and £712,500 per megawatt to hold a place in that queue. Britain holds more claimed demand than the country consumes at peak.
Mehdi Paryavi, who runs the International Data Center Authority, told Asharq Al-Awsat on 21 July 2026 that energy is the largest constraint on AI growth. He placed it above chips and capital, and ahead of workforce and public policy. Saudi Arabia operated 467 megawatts in the first quarter of 2026 against a national target of 1.5 gigawatts by 2030. Alvarez & Marsal put the binding questions for Saudi delivery at offtake quality, construction risk allocation, and whether debt can be shown to be repayable.
All three regions are constrained by the same input. Only one of them is obliged to count.
Why Britain Has a Number
Britain rations grid connection. Rationing requires a queue. The queue is a register: every project that wants power holds a position in it, with a capacity figure and a connection point attached. Once that register exists it can be counted, and once counted the count can be published.
Ofgem published one on 29 July 2026. Contracted demand offers across Great Britain rose from 41 gigawatts in November 2024 to 125 gigawatts in June 2025. The consultation carrying those figures was issued more than a year after that second date. June 2025 remains the latest basis in the public record.
Data centres account for around 73 gigawatts of that total across roughly 315 projects. The published size bands show where the volume sits: 11 projects below 10 megawatts, 47 between 10 and 50, and 51 between 50 and 100. Those 109 projects total about 4.9 gigawatts. The remaining projects carry the balance, which puts their average near 330 megawatts each. That arithmetic is mine rather than Ofgem’s.
Ofgem’s proposed response prices the act of holding a position. Data centre projects above 40 megawatts would post between £237,500 and £712,500 per megawatt of requested capacity. The sum would be secured from acceptance of a connection offer until the site energises, returned on energisation, and forfeited on exit. On a 500 megawatt campus that is between roughly £119 million and £356 million held for the length of a build. The consultation does not specify whether the security takes the form of cash, a bond, or a guarantee.
The same regulator prices the same problem differently for a different applicant. A separate code change, CMP448, introduced a progression commitment fee for generation and storage projects. It has been live in the code since 2 January 2026 and remains dormant until an activation threshold is reached. If activated it begins at £2,500 per megawatt and rises in steps to a ceiling of £10,000. The data centre proposal starts at roughly twenty-four times that ceiling.
What the fee tests is published alongside it. A project holding a position would have to show a credible end user for the compute, evidence of long-lead electrical equipment procurement, and financial and technical capability to deliver. Those are the questions a lender asks. Ofgem is asking them at the connection point and charging for the wrong answer.
Germany Moved the Rule Instead
Germany’s constraint on data centres was written into statute rather than imposed by the network. The Energy Efficiency Act set power usage effectiveness targets. It also required operators to cover their electricity consumption entirely from renewable sources on a balance-sheet basis by 1 January 2027, and to make waste heat available.
The federal cabinet adopted a draft amendment on 24 June 2026 that moves all three. The renewable obligation shifts to 1 January 2030. Facilities operating before July 2026 see their power usage effectiveness ceiling rise from 1.5 to 1.6 for July 2027, and from 1.3 to 1.4 for 2030. New facilities keep the 1.2 target while gaining four years to reach it instead of two. The waste heat duty narrows to sites where a heat network is reasonably available. This is a government draft. It still requires passage through the Bundestag and the Bundesrat.
The amendment is framed as accelerating Germany’s outstanding transposition of the recast Energy Efficiency Directive. The European Commission issued a letter of formal notice to Germany and twenty-five other member states on 21 November 2025 for missing the transposition deadline. Germany eased its domestic data centre requirements while those proceedings were open.
The German Data Center Association published a position paper on 17 April 2026 arguing the original targets were unworkable. The wind industry association and the energy efficiency lobby criticised the easing after the cabinet decision. No German data centre project has been publicly cancelled, relocated, or paused citing the pre-amendment targets.
Germany is tightening in the other direction at the same time. A cabinet package of 29 July 2026 covers connection priority, capacity reservation and curtailment compensation. It remains a draft in parliamentary process. Separately, the four transmission system operators published a maturity-based allocation concept in February 2026 and began moving toward implementation for large loads from April under the regulator’s oversight. The principle is first ready, first reserved: allocation by how advanced a project is rather than by when it applied. The national Data Centre Strategy adopted on 18 March 2026 carries the same approach.
An allocator holding German exposure is watching two drafts at once. One loosens what a facility must achieve. One changes how it gets connected. Neither is yet law.
What Nobody Is Required to Count
Saudi Arabia has an application process for large loads without a register behind it. The Saudi Arabian Grid Code sets out connection studies, network impact assessment and connection offers. A developer can fund its own substation or pursue captive generation rather than wait. Connection agreements address minimum capacity commitments and baseload assumptions. Grid connection, capacity allocation, tariffs and reliability standards sit with the Saudi Electricity Regulatory Authority alongside the Ministry of Energy.
No public list exists of who has requested how many megawatts, at which connection point, with what energisation date. The same holds for the UAE, where DEWA and Etihad Water and Electricity publish infrastructure investment figures and substation counts without a rules-based connection policy for loads at data centre scale. No fee, deposit, or forfeiture attaches anywhere in the Gulf to holding an allocation that has not energised.
Operational capacity is reported without a single official series behind it. Saudi figures in circulation for roughly the same period run from about 290 megawatts to 410, 440 and 467. The differences depend on whether the count covers IT load or facility capacity, third-party colocation or enterprise sites, and on when the snapshot was taken. Across the GCC, installed capacity sits near 870 to 900 megawatts against roughly 4 gigawatts described as under development between 2024 and 2028.
Alvarez & Marsal put Saudi Arabia’s base case at growth from about 410 megawatts to roughly 1 gigawatt by 2030. That would require project capital of $7 to $9 billion, with $3.5 to $7 billion of that in debt. On the more ambitious case, where around half of announced capacity is delivered, the figures rise to $28 to $42 billion of capital and $14 to $32 billion of debt. Kurt Davis Jr describes that debt figure as more than the kingdom’s banks are likely to assemble themselves. His stated obstacles are securing long-term customers, allocating construction risk, and demonstrating how the debt gets repaid.
Those are the three tests Ofgem wrote into its milestone requirements. A British project must evidence a credible end user, procure long-lead equipment, and show financial and technical capability, or forfeit its deposit. A Saudi project answers the same questions to a credit committee. One filter is a published consultation with a comment deadline. The other is distributed across private lending decisions and produces no aggregate number.
In Britain, the distance between 125 gigawatts of contracted offers and 45 gigawatts of national peak demand is visible to anyone who reads the consultation. In Saudi Arabia the equivalent distance is established privately, one facility at a time, by whoever is lending.
What an Allocator Cannot Yet Observe
Two markets rewrote the terms of grid access between April and July 2026. No public record yet shows either change being priced. No investor, lender, or rating agency has stated publicly that it has repriced or withdrawn a British or German data centre position because of them. Ofgem has published no queue exit count since its June positions. No German project has been publicly accelerated or delayed citing the cabinet draft. The consultation closes on 16 September 2026 and a decision is intended later in the year.
The exposure the middle ground creates is a rule that moves after capital is committed. Ireland’s answer was binary and disclosed: a project either cleared the conditions or it did not, and the constrained area map published in May 2026 told developers in Dublin the answer was no. A British project that accepted a connection offer in 2025 now faces a proposed fee that did not exist when it applied, on terms not yet settled, in a form Ofgem has not specified. A German facility built against a 2027 renewable deadline now operates under a draft moving that deadline to 2030. That changes the economics of procurement decisions already made.
Mandatory curtailment sits further out. Ofgem will report to the AI Energy Council in autumn 2026 on whether voluntary flexibility from data centres is sufficient. It has said it will consider backstop measures including compulsory curtailment if it is not. A project financed today in Great Britain carries a curtailment question with no answer. That is different from a known non-firm connection where the terms are written into the agreement.
No named commitment by a Gulf sovereign fund, family office or operator into a British or German data centre asset during 2025 or 2026 could be identified in the public record. Whether that reflects absent exposure or undisclosed exposure is not something the record settles.
What to Ask
Three claims opened this piece and none survives the record. American capital is running ahead of the power available to absorb it. Britain holds more claimed data centre demand than the country consumes at peak and is proposing to charge developers to establish which claims are real. The Gulf’s constraint is named by the people who measure the sector as energy, ahead of chips and capital both.
The questions that follow are the same in each place. Whether a credible end user exists for the compute. Whether long-lead electrical equipment has been ordered. Whether the debt can be shown to be repayable. Ofgem asks them at the connection point and charges between £237,500 and £712,500 per megawatt for the wrong answer. Alvarez & Marsal report lenders asking them of Saudi projects. What differs is where the asking happens and whether the result is written down anywhere a third party can read.
A British position carries a published queue, a published consultation, a comment deadline, and a proposal whose final form is unknown. A Gulf position carries a connection agreement, a credit committee, and no aggregate figure against which to check what any single announcement is worth. They produce different diligence work.
Britain now has a public number for the distance between what has been requested and what the system can carry. Anywhere without a published queue, that distance still exists and has to be established one project at a time.
Generating power and delivering it to a site are separate problems, and the next piece takes up the second. Spain is curtailing solar it has already built because the transmission to move it does not exist. Groningen has the grid and no spare capacity on it to allocate. Both bear on a Gulf case that rests on cheap generation.
Note for the reader: This is analysis of how these markets are structured and financed, written by someone who spends his time following how capital moves across borders and into infrastructure. It is not investment advice and not a recommendation on any asset, programme or jurisdiction.
