Lake Mariner Building 4 completion by mid-2024
Company: TeraWulf - Project: Akela Data
What the later record shows
Delivered; the record does not say when
Building 4 was meant to take Lake Mariner from 160 MW to 195 MW. Lake Mariner was still at 160 MW on May 31, 2024, and a later chart shows 195 MW by 3Q 2024, so it was finished, but nothing shows whether that happened by June 30.

How we checked this
Checked on November 11, 2026. The cited source supports every part of this claim.
TeraWulf's March 6, 2024 press release states the funding status, mid-2024 completion target, 35 MW addition and approximately 10 EH/s capacity. These were company expectations at that date, and the document does not show whether they were later achieved.
Confirmed in the source:
- Construction of Building 4 at TeraWulf's Lake Mariner facility was substantially funded as of March 6, 2024.
- Building 4 was on track for completion by mid-2024 as of March 6, 2024.
- Building 4 was anticipated to add an incremental 35 MW of capacity.
- The additional infrastructure was expected to increase TeraWulf's operational mining capacity to approximately 10 EH/s.
What we did: Read our cached copy of SEC EDGAR (8-K Ex) (https://www.sec.gov/Archives/edgar/data/1083301/000108330124000053/wulf23resultsand24outloo.htm) in full (18,117 characters, retrieved November 9, 2026) and checked each assertion in the claim against it.
