This is a source-attributed discovery row. It can help you find a place and its citations; it is not a DataCenterData finding that the facility is distinct or currently operating.

What the source record says
This is the HPC data center inside the Energy Systems Integration Facility (ESIF) on the lab campus in Golden. It houses the Kestrel supercomputer (HPE, CPU plus GPU nodes), which arrived in March 2023. The lab needed '2.5-megawatt upgrades to support Kestrel'. A total facility MW figure was not in the fetched pages, so capacityMw is omitted. Coordinates are a Census geocode of the lab's 15013 Denver West Pkwy campus address, not the ESIF building itself.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.

Compute Atlas 1.34.1 with retained prior rows and publication holds. This is a DataCenterData composite, not an unmodified publisher edition. This row uses the captured source from 1.34.1, source as of 2026-10-14T20:40:52.293Z.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
