When the conversation turns to AI infrastructure bottlenecks, data centers dominate the discussion. But there is another category of facility with equally extreme power requirements that is being built across Europe right now — semiconductor fabrication plants. And they face exactly the same transformer shortage and grid connection challenges.
HOW MUCH POWER A FAB ACTUALLY CONSUMES
A modern semiconductor fabrication plant is one of the most electricity-intensive industrial facilities ever built. The numbers are striking:
Mature node fab (28nm+): 100–250 MW continuous
Memory fab (DRAM/NAND): 200–400 MW continuous
Comparison: a large AI data center = 100–300 MW
A major fab consumes more electricity than most data centers
Unlike a data center, a fab cannot tolerate power interruptions. Even a momentary voltage fluctuation can destroy an entire wafer batch worth millions of euros. Fabs require not just large power — they require extraordinarily stable, clean power with redundancy that exceeds even the most demanding data center specifications.
THE EUROPEAN CHIPS ACT — A WAVE OF FAB CONSTRUCTION
The EU Chips Act, enacted in 2023, commits €43 billion to strengthen European semiconductor manufacturing. The goal: double Europe's share of global chip production from 10% to 20% by 2030. The projects already announced represent a significant new wave of industrial electricity demand across the continent.
TSMC — Dresden, Germany: advanced packaging + logic, ~300 MW
STMicroelectronics — Crolles, France: 300mm expansion, ~200 MW
Wolfspeed — Ensdorf, Germany: SiC power semiconductors, ~100 MW

Each of these projects requires transformer procurement, grid connection studies, and power equipment that is subject to the same lead times and shortages as AI data center projects. The Intel Magdeburg project alone requires more grid capacity than a mid-sized European city.
THE ASML SIGNAL
ASML's CEO has stated that the semiconductor market will remain supply-constrained for years, with demand extending beyond data centers into satellites, robotics, humanoids and connected devices. This is significant because ASML manufactures the lithography machines — the EUV systems — without which leading-edge chips cannot be produced.
When ASML signals years of supply constraint, it is signalling years of fab construction and expansion. Every new fab is a massive power infrastructure project. The grid connection, transformer procurement and electrical equipment challenges are identical to those of data centers — and the power requirements are often larger.
WHERE FRANCE SITS IN THIS PICTURE
France has specific advantages for semiconductor manufacturing beyond its general electricity position. STMicroelectronics has a major presence in Crolles (Grenoble area) and Tours. The French government has designated semiconductor manufacturing as a strategic priority under France 2030.
The Crolles expansion alone requires significant grid capacity additions from RTE. The French nuclear electricity advantage — stable baseload at competitive prices — is even more valuable for fabs than for data centers, because fab power quality requirements demand the stable frequency and voltage that nuclear baseload delivers more reliably than intermittent renewable sources.
THE POWER INFRASTRUCTURE CHALLENGE FOR FAB DEVELOPERS
Fab developers face the same power infrastructure bottleneck as data center developers, with three additional complications:
- Power quality requirements are more stringent — voltage fluctuations that a data center UPS would handle cleanly can damage fab equipment
- Water requirements are enormous — ultra-pure water production consumes significant additional electricity
- Ramp timeline pressure is acute — a fab that cannot power up on schedule loses months of production from billion-euro equipment sitting idle
WHAT GRIDREADINESS CAN DO FOR FAB PROJECTS
Our grid readiness analysis, site selection and transformer sourcing services apply directly to semiconductor fab projects. The power requirements are larger, the quality specifications more demanding, and the consequences of grid connection delays more severe.
