Nautilus 50 MW expansion online in 2025
Company: TeraWulf - Project: Nautilus
What the later record shows
Outcome not yet confirmed
No passage says whether the additional 50 MW at Nautilus came online, slipped or was dropped. The 50 MW at Nautilus cited in April 2024 is the existing capacity. Later filings tie the Nautilus share mainly to 2024 periods, and the 2026 filings report only Lake Mariner, which hints at an exit, but no passage says so outright.
“Operational infrastructure capacity at the Lake Mariner facility was 160 MW plus 50 MW at Nautilus with TeraWulf’s total self-mining hash rate at 8.0 EH/s.”

The claim, verbatim
TeraWulf exercised its option to add 50 MW of energy capacity at the Nautilus facility, doubling its bitcoin mining capacity at the Pennsylvania site to 100 MW. The additional capacity is expected to come online in 2025 and could support up to 2.5 EH/s of mining capacity.
