Utility, ISO and nearby assets are derived from the site's location. Proximity to a substation or line doesn't establish the interconnection; that needs a utility filing or interconnection-queue record. Queue requests are applications, not commitments — most never reach operation.

Timeline

Construction start: Jun 25, 2024[1]
First operational: Mar 13, 2026[1]
  1. Jun 25, 2024[1]

    Core Scientific announced that CoreWeave would receive about 70 MW of HPC infrastructure from 100 MW of owned infrastructure. Site modifications were expected to begin in H2 2024.

  2. Mar 13, 202650 MW facility power· 1 buildings operational[1]

    The site has been energized. Two of three data halls had been delivered at 37 billable MW, supporting about 15000 Grace Blackwell GPUs. The third hall was still in commissioning.

  3. Apr 17, 202650 MW facility power· 1 buildings operational[1]

    Satellite imagery shows the main data hall and southern utility yard substantially complete. No new public MW disclosure, so this keeps the March 2026 public 36 MW state.

  4. May 6, 202691 MW facility power· 1 buildings operational[1]

    Core Scientific said Marble was fully handed over to CoreWeave with about 65 MW of billable customer power online.
