Black Pearl data center facility lease and asset acquisition
Company: Cipher Mining
What the later record shows
Delivered; the record does not say when
Later filings say Cipher Black Pearl assumed the Winkler County lease, with a ten-year initial term and four ten-year renewals, and that the site holds conditional ERCOT approval for 300 MW. No passage gives the closing date, so on-time delivery cannot be confirmed.
“The Black Pearl Facility has conditional ERCOT interconnection approval of up to 300 MW.”
