Total power capacity in 2025
Company: Cipher Mining
What the later record shows
Partly delivered
Operating capacity reached about 477 MW in 2025, not about 927 MW. Barber Lake and Black Pearl Phase II were turned into HPC builds still under construction, the JV stakes were later divested, and the 2025 summary cites only 207 MW of operating bitcoin mining power.
