TeraWulf-owned Lake Mariner campus on the shores of Lake Ontario at a former Somerset/Niagara coal plant (Barker, NY). The site serves a mix of crypto-mining and AI computing; only the AI buildings are tracked here. Buildings 1-2 (70 MW) are leased to G42 subsidiary Core42; Buildings 3-5 (440 MW) are leased to Fluidstack under a 10-year AI hosting agreement (Fluidstack's buildings serve Google TPUs for Anthropic). 510 MW reflects the disclosed sum across both tenant blocks; Epoch's prior 68 MW substrate figure pre-dated the full multi-tenant build-out.
