Nautilus Cryptomine facility capacity: 200 MW initial, expandable to 300 MW by May 13, 2024
Company: TeraWulf - Project: Nautilus
What the later record shows
The date slipped · new target February 28, 2025
The Talen/Cumulus expansion window was restructured to run within twelve months of TeraWulf's February 28, 2024 election. The expansion had not occurred as of September 30, 2024, after the original May 13, 2024 date, and no passage shows the facility reached 300 MW.

How we checked this
Checked on October 11, 2026. The cited source supports every part of this claim.
TeraWulf's March 2023 8-K states the facility initially requires 200 MW and that Cumulus Member may elect, before May 13, 2024, to expand by up to 100 MW for a total of 300 MW.
Confirmed in the source:
- The Nautilus Cryptomine facility will initially require 200 MW of electric capacity
- The energy requirement may be expanded by up to 100 MW for a total capacity of 300 MW
- Cumulus Member may elect the expansion prior to May 13, 2024
