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.

  1. Feb 18, 2022[1]

    Land clearing for the site is almost complete. Informed using imagery on Google Earth

  2. Jul 1, 202426 MW facility power· 1 buildings operational[1]

    Building 1 operational. The first 2 data halls of Building 1 (with chillers already installed) are likely to be already operational. Although construction was completed prior, the on-site substation was previously incomplete, so we believe it was only operational at this point.

  3. Aug 3, 202526 MW facility power· 1 buildings operational[1]

    Building 2 chiller installation is a little more than halfway complete, and chiller installation for the last data hall of Building 1 is also around halfway complete.

  4. Feb 28, 202626 MW facility power· 1 buildings operational[1]

    No more visible construction around either building, just a little equipment. Roads fully built around buildings as well.

  5. Mar 31, 202666 MW facility power· 2 buildings operational[1]

    Building 2 fully operational, Building 1 expanded. Construction is already visibly complete. Additionally, construction phases Phase 2, Phase 3, and Phase 4 on TDLR that collectively represent the completion of the site have a completion date of 2026-03-31.
