Bear & Chief 30 MW expansions energization
Company: Cipher Mining
What the later record shows
Delivered; the record does not say when
Later filings list Bear and Chief at 40 MW each, which is consistent with the 30 MW expansions being finished. No passage gives an expansion completion date or the sites' earlier size, so timing against Q2 2024 cannot be determined.
