Bear and Chief JV 30 MW expansions
Company: Cipher Mining
What the later record shows
Delivered; the record does not say when
Bear and Chief are later shown at 40 MW each, with 120 MW across the JV sites, which is consistent with the expansions being completed. No passage says when they finished or confirms the ~1.25 EH/s added, so on-time delivery cannot be determined.
