Black Pearl energization 2Q 2025
Company: Cipher Mining
What the later record shows
Partly delivered
Black Pearl Phase I (150 MW) was energized by August 2025, but the remaining 150 MW was repurposed toward HPC rather than energized in 2Q 2025. The whole site later became a 300 MW HPC build for AWS.
