Data centers have 660 MW connected in Mainova's area, about 20% of grid consumption; an operator expects no relevant new power in Frankfurt for about ten years.

What this evidence bears on

• Supports: Grid limits are regional, so a single city's yes or no misses the real constraint. In Frankfurt data centers already use about a fifth of the power on the city grid, and operators expect no relevant new capacity there for about ten years.

  • A reason for “Leave it to grid operators and national rules: steer data centers to places with spare clean power instead of city by city decisions.”
