Lake Mariner Building 5 brings total capacity to ~300 MW
Company: TeraWulf
What the later record shows
Partly delivered · happened April 30, 2025
The 50 MW Building 5 expansion came online in April 2025, just after the Q1 2025 date, with 225 MW in operation in Q1 2025. That implies about 275 MW rather than ~300 MW, and no passage shows the 300 MW total being reached.
“225 MW in operation Q1 2025 ➢ 50 MW (MB-5) expansion online April 2025 ➢ Targeting 225 MW and 12 EH/s for Q2 – Q42025”
