POWER AVAILABILITY VS POWER DELIVERABILITY
A critical distinction that most analysis misses: theoretical power availability and real deliverable megawatts are not the same thing.
France has theoretical power availability — nuclear baseload generates approximately 400 TWh/year. But deliverability depends on local grid infrastructure: substation capacity at the specific connection point, queue position relative to competing projects, and transformer procurement timeline. A site that appears "grid-connected" may still face 18-24 months of reinforcement works before it can receive its contracted capacity.
GridReadiness evaluates deliverability — not theoretical availability. The distinction is the difference between a site that powers up in 2027 and one that does so in 2030.
FRANCE POWER AVAILABILITY — KEY METRICS
Nuclear baseload: 70% of electricity · €50–70/MWh · 24/7 firm power
Carbon intensity: 58 gCO2/kWh
RTE brownfield connection: 18–36 months
RTE fast-track sites: 4 sites · 400–1,000 MW each · CRE approved May 2025
Available transformer capacity: Schneider France 18–26 months · Efacec 20–28 months
Government sites: 63 pre-qualified · 8 with 1 GW+ capacity
Total pipeline: 280 GW of EU requests — France absorbing major share
NUCLEAR POWER — WHY IT MATTERS FOR AI
AI data centers require firm, dispatchable power — electricity available 24/7 regardless of weather or time of day. Nuclear power uniquely provides this at scale. France operates the largest nuclear fleet in Europe, generating approximately 400 TWh per year.
- Baseload pricing: €50–70/MWh vs €90–120/MWh (Germany) vs $60–90/MWh (US gas, variable)
- Availability: >90% capacity factor vs 25-35% for solar/wind
- Carbon: 58 gCO2/kWh — hyperscaler sustainability targets compatible
- Stability: nuclear price is not linked to gas markets — predictable for long-term PPA structuring
RTE POWER AVAILABILITY — WHAT THE PROCESS MEANS
RTE (Réseau de Transport d'Électricité) manages France's high-voltage transmission network. Grid power availability for a new data center depends entirely on the RTE connection process:
Brownfield site (existing HV connection): 18–36 months
Greenfield site (new connection): 3–5 years
RTE fast-track sites: compressed procedure approved by CRE · 4 sites available · 400–1,000 MW
Pre-reservation: industrial operators can reserve capacity in advance (fast-track process)
Key contact: RTE Direction des Relations Industrielles
The brownfield advantage is fundamental: a former industrial site that already has a 63kV, 90kV or 225kV connection does not need to go through the standard RTE queue. This is the single most important factor in French AI data center power availability.
POWER AVAILABILITY — CLOSED MARKETS VS FRANCE
Ireland: moratorium until 2028 — data centers already >20% of national demand
Netherlands: new connections effectively banned until 2030
Frankfurt: new connections banned until 2030
Spain: grid fragility highlighted by 2025 blackout
France: OPEN — 18–36 months brownfield · 4 fast-track sites · nuclear available
