Lake Mariner first phase online by year end 2022
Company: TeraWulf - Project: Lake Mariner Anthropic AI Factory
What the later record shows
Delivered; the record does not say when
Later filings show Lake Mariner well past 100 MW, with 160 MW energized by March 31, 2024. No passage says when the first ~100 MW phase came online, so whether it met year-end 2022 cannot be determined.
