Bucharest ClusterPower 800MW Off-Grid AI Infrastructure Factory

Status: Under Construction (Phase 1 Fast-Track)   |   Location: Strada Viitorului nr.2, 207405 Mlecănești, Romania


Project Overview

The Bucharest ClusterPower Super-Campus marks a historic evolution in European digital infrastructure, conceptualized as a specialized "AI Factory" to sidestep the continent's severe electrical grid bottlenecks. Moving completely away from legacy utility infrastructure, this massive 800MW development implements a "Bring Your Own Power" (BYOP) strategy. The site features an innovative Behind-the-Meter (BTM) on-site power generation matrix composed of highly efficient aeroderivative gas turbines engineered for immediate hydrogen blending. This reliable energy setup completely compresses conventional multi-year grid interconnection wait times down to a rapid 12-month delivery window, creating a resilient, sovereign cloud hub capable of supporting heavy computing workloads across continental Europe. Architecturally optimized for modern high-performance computing (HPC) setups, the campus is designed in direct collaboration with NVIDIA to host dense next-generation hardware configurations like the GB200 architecture. To handle the incredible thermal generation of these clusters, which easily reach or exceed 100kW per rack, the complex bypasses traditional air conditioning entirely for direct-to-chip liquid cooling systems. This advanced mechanical arrangement extracts waste heat to feed into a regional district heating network, allowing the facility to push its targeted Power Usage Effectiveness (PUE) to a class-leading 1.12.
