Lake Mariner 35 MW expansion operational mid-2024
Company: TeraWulf - Project: Lake Mariner Anthropic AI Factory
What the later record shows
Delivered; the record does not say when
In May 2024 total capacity was 210 MW with 35 MW under construction. By the August 12, 2024 10-Q it was 245 MW (Lake Mariner ~195 MW, up from 160 MW), so the 35 MW came online by then, but no passage says whether it was by June 30.
“As of the date of this Quarterly Report, the Company has a total operational capacity of 210 megawatts (“MW”)”
