Volume 4 and closure of the 'Digital Sovereignty' series. The fourth layer, flagged from Volume 1 as the authentic limit of the doctrine, does not compose like the previous three: it is allocated.
Volume 4 closes the “Digital Sovereignty” series by treating the energy layer as the structural limit of the architectural doctrine. The previous three volumes established that infrastructure sovereignty signs by a cryptographic chain of four ports, that fabric sovereignty composes layer by layer across the seven floors of the material stack, and that model sovereignty is instrumented by an auditability-data-versions triad. The energy layer admits none of these instruments. It is allocated by a Transmission System Operator (TSO) within multisectoral national planning, not designed by the deployer. The deployer composes with the grid; he does not architect it.
The opening gap of Volume 4: installed capacity is a commercial category, allocated capacity is an engineering category. Announcements of gigawatts, capex, and campuses operate in the financial regime; firm allocation, frequency stability, inertia, local congestion, transformer availability, and dispatchability operate in the physical regime of the grid. The 1.4 GW Franco-Emirati AI campus (Bpifrance, MGX, Mistral AI, NVIDIA), announced at Choose France in Versailles on 19 May 2025 with a 2028 commissioning target, illustrates the gap: the investment decision is engaged, the grid decision is not. The Réseau de Transport d’Électricité (RTE) submitted its 2025 Schéma Décennal de Développement du Réseau (SDDR) to public debate before the Commission nationale du débat public from 4 September 2025 to 14 January 2026, where three priorities are arbitrated together: industrial decarbonization, accommodation of new consumers (datacenters included), and decarbonized generation development. The narrative economy of AI operates on financial objects; the electrical economy operates on physical objects.
The doctrine deploys as an irreducible triad. Allocation is rivalrous. IEA reports global datacenter electricity consumption rose from 415 TWh in 2024 to 485 TWh in 2025 (+17%), projected at 945 TWh by 2030 in the base case, with European growth of approximately 70% over the period. The ENTSO-E report Data centres and the power system of 8 May 2026 counts about 12.7 GW of installed IT capacity across 10,500 European datacenters and warns that TSOs may have to reduce renewable penetration if datacenter growth is not regulated.
The connection calendar exceeds any AI cycle. RTE recommends 18 to 36 months for any project above 10 MW. The Lawrence Berkeley Laboratory’s Queued Up report (May 2025) documents US connection delays rising from under 2 years (2000-2007 cohort) to a median of 5 years (2023 cohort). A frontier model generation amortizes over 12 to 18 months; an industrial connection takes 24 to 36; a structuring electrical generation program 10 to 15 years.
Capacity factor is proven, not promised. AI training loads run at 80 to 95% capacity factor with rapid power transitions documented by the IEA in Key Questions on Energy and AI (2026). Photovoltaic plants operate at 12 to 15% mean annual capacity factor, onshore wind at 25 to 30%, offshore wind at 35 to 45%. A claim of 100% renewable supply is verified in the hourly mix and time-stamped guarantees of origin, or it is not verified at all.
Keystone pivot of Volume 4: a PPA is a decision longer than a model. The Microsoft-Constellation agreement on Three Mile Island Unit 1 (Crane Clean Energy Center), signed September 2024, covers 835 MW for 20 years, with restart accelerated from 2028 to 2027 after the US Department of Energy closed a $1 billion loan to Constellation on 18 November 2025. The Amazon-Talen agreement on Susquehanna, expanded 11 June 2025, covers 1,920 MW through 2042 with about $18 billion in contracted revenues and a “front-of-the-meter” transition in spring 2026. The Meta-Constellation agreement on Clinton, signed 3 June 2025, covers 1,121 MW for 20 years from June 2027 on a site initially programmed for decommissioning, with a 30 MW capacity uprate. On the French side, EDF’s EPR2 program, capped at €72.8 billion (2020 value) for six units, validated by the Board of Directors on 18 December 2025, targets a final investment decision by end of 2026, first concrete at Penly in March 2029, commissioning in 2038. Once AI becomes an industrial consumer of dispatchable power at the gigawatt scale, it ceases to be arbitrated by the digital market alone: it enters the strategic arbitrage matrix of the energy state, where it competes with decarbonized steel, industrial hydrogen, electrification of heavy transport, and grid resilience requirements under NIS2.
Four constraints, four CTO questions, four minimum proofs, four risks. Audit instrument, not benchmark.
| Constraint | CTO question | Minimum proof | Risk if absent |
|---|---|---|---|
| Allocated capacity | Does the site hold a connection agreement signed with the TSO, or merely a letter of intent? | RTE or equivalent national TSO agreement signed, indexed to a maximum drawable power, dated. | Commitment presented as guaranteed when it depends on a future SDDR; allocation reclassified in case of industrial prioritization. |
| Calendar | When is the source substation delivered, distinct from the datacenter opening date? | Energization schedule provided by the TSO, independent audit of critical milestones. | IT commissioning ahead of energization, operation on diesel gensets or captive gas. |
| Concordance | What share of the load is covered by long-term PPA (15 years and above), what share by wholesale market? | Declared supply contracts, weighted average duration, spot price exposure, time-stamped guarantees of origin. | Marginal inference cost not bounded over the contractual horizon, sustainability defect under CSRD. |
| Carbon intensity | What is the average and marginal carbon intensity of the localization grid, attested by an independent certifier and causally localizable? | EEA and Ember data at annual resolution, hourly GO certificates, documented Scope 2 GHG Protocol methodology, declared causal attribution of compute. | Environmental claim not defensible under applicable consumer and sustainability law. |
In the United States, hyperscalers internalize the electrical generation decision. Stargate (announced January 2025 at the White House, $500 billion, 10 GW by 2029, of which 7 GW already allocated by September 2025); Anthropic (a complementary $50 billion infrastructure investment announced November 2025); about $400 billion of combined 2025 capex from five major technology groups with announced 75% growth for 2026; the global pipeline of conditional SMR offtake rose from 25 GW at end-2024 to 45 GW in May 2026 according to the IEA; about 38 GW of captive gas in development (Global Energy Monitor), of which roughly a quarter is dedicated to datacenters. The AI load installs itself next to the power plant, or the power plant restarts for the load.
In Europe, deployers compose with a historical operator under regulatory and political oversight. The Mistral 1.4 GW campus is pending RTE instruction, commissioning announced for 2028. AWS European Sovereign Cloud has been generally available since 15 January 2026 in Brandenburg with €7.8 billion of investment, operated under German law and scrutinized by the Bundesamt für Sicherheit in der Informationstechnik (BSI). EDF’s EPR2 program is cadenced over 2029 to 2050. RTE published 35 ready-to-build sites for accelerated 2028 connection, concentrated in Hauts-de-France, Normandy, and marginally Île-de-France. The European deployer purchases supply, does not buy a power plant, and does not trigger, by its decision alone, the construction of a new generation unit. It signs a calendar it did not write.
The General-Purpose AI Code of Practice, published by the AI Office on 10 July 2025, operationalizes Article 53 of the AI Act. Article 53 obligations entered into application on 2 August 2025 for new GPAI models; pre-existing models have until 2 August 2027 to comply. The Transparency Section, articulated to Annex XI, requires every provider to complete a Model Documentation Form covering architecture, training data, computational resources, and energy consumption of training, retained ten years. Article 53 sanctions reach €15 million or 3% of worldwide turnover.
The final version introduces a clear-text exemption on energy disclosure: providers are exempted from disclosing the amount of energy used to train a model when they lack critical information from a compute or hardware provider. The legislator acknowledges, in the very wording of the obligation, that the energy traceability of a model trained at a third party may be unavailable. An obligation whose own waiver is provided for by the legislator is not an obligation; it is a declaration of intent. The exemption reflects a structural property the present volume names: causal non-localizability of energy. Compute is dynamically routed across regions, GPU allocation is shared, the production mix varies hour by hour, guarantees of origin are fungible at annual scale. The causal chain fractures across four actors: the model provider externalizes compute, the cloud provider externalizes electricity, the TSO externalizes generation, the PPA externalizes the guarantee of origin. The marginal energy of an inference is not localized; it is declared.
The CSRD inscribes training energy consumption within the perimeter of sustainability reporting. On consumer-facing claims, the regulatory landscape is in motion: the Green Claims Directive proposal (deposited March 2023) was the subject of a withdrawal announcement by the Commission on 20 June 2025 without formal withdrawal at the date of Volume 4; the file is dormant. The effectively applicable instrument is the Empowering Consumers for the Green Transition (ECGT) Directive, adopted March 2024, transposition by 27 March 2026, application from 27 September 2026, prohibiting in particular generic non-substantiated environmental claims and offset-based carbon-neutrality claims. As an order of magnitude, the average 2023 carbon intensity of the European electricity mix stands at 242 gCO2/kWh according to Ember (Poland 662, Czechia 450, Germany 371, Sweden and France among the lowest). A model trained in Poland and a model trained in France are not the same regulatory object with respect to sustainability reporting.
NIS2 does not “requalify” datacenters by their grid connection. Datacenter service providers are listed directly in Annex I of the directive (digital infrastructure): large enterprises (250+ employees or €50M+ turnover) as essential entities, medium enterprises (50+ employees or €10M+) as important entities. Qualification is sectoral and size-linked, not connection-based. The energy interface translates into Article 21 obligations on supply-chain security and critical dependency on regulated sectors (energy also figures in Annex I), with national authorities ANSSI in France and BSI in Germany.
Of four layers, three admit architectural compensation proper to the deployer: proof compensates imperfect custody (Volume 1), diversification compensates non-European silicon (Volume 2), instrumentation compensates imperfect model auditability (Volume 3). An absence of allocated energy admits no equivalent fallback on the deployer side. A site without its connection agreement on the planned opening date can defer commissioning (downstream misalignment), switch to captive gas (carbon intensity degraded, CSRD/ECGT defensibility compromised), or give up on the site (infrastructure investment invalidated). None of these outcomes preserves at once the industrial trajectory, the regulatory trajectory, and the environmental trajectory.
This is why the fourth doctrinal operator is allocation. Energy sovereignty is a sovereignty under allocation, opposable to the deployer in long time. On the first three layers, sovereignty is what one proves. On the fourth, sovereignty is what one obtains. The four-volume arc resolves to one sentence: three layers are instrumented, the fourth is allocated. The next leap is no longer a fifth layer: it is the transformation of the composite doctrine into an executable instrument, audit protocol, signed arbitrage grid, qualification method opposable to an architecture review board or notified body. The arc is complete; the audit remains to be instrumented.
