Solving the AI Power Grid Bottleneck

Why hyperscalers, fusion startups, and utilities are converging on next-generation on-site clean power.

Substation Interconnection Queues

Traditional utility grid interconnects now face 4 to 7 year delays across PJM, ERCOT, and CAISO. High-density AI training clusters exceeding 100 MW require dedicated behind-the-meter generation or transmission upgrades before compute clusters can energize.

SMR Nuclear & Commercial Fusion

Unlike intermittent solar and wind, advanced nuclear fission (SMRs) and magnet-confined fusion provide continuous 24/7/365 firm power without costly gigawatt-hour battery banks, directly matching the continuous 95%+ baseload factor of foundational training models.

PUE & Liquid Cooling Density

As rack power densities surpass 100 kW to 150 kW per rack for next-gen GPU clusters, direct-to-chip liquid cooling and two-phase immersion bring PUE down from 1.45 to <1.15, eliminating dozens of megawatts of parasitic chiller load from the local substation.
