Black Pearl 300 MW energization Q2 2025
Company: Cipher Mining
What the later record shows
Partly delivered
By August 2025, only Phase I (150 MW) of Black Pearl had been energized. Phase II was redirected to a hybrid mining/HPC plan, and the site was later retrofitted to HPC, so the full 300 MW was never energized for mining.
