German EnEfG §11 requires the new-operation cohort from July 1, 2026 to meet an annual PUE no greater than 1.2

≤1.2 annual PUEobserved

Value kindobserved — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range.
ScopeApplies to Germany's new-operation cohort: the annual average must be reached within the statutory period, inside the statute's energy boundary. It is not a global site-design target. A September 2026 government bill (Bundestag Drs. 21/8027) would keep the 1.2 PUE but allow four years instead of two to reach it; check its status before fixing a commissioning plan.
