Flood release is not total release. Local watershed inflow and storage change matter to reconciliation.

WOLF HOLLOW

Different boundaries, different numbers

Design intake9.9 MGD
2020–2024 average1.727 MGD
Non-contact cooling share93.2%
2024 Jun–Sep gross proxy~1,271 AF

CAUTION: design capacity, measured/recorded intake, cooling share and annual customer ledger values are not interchangeable.
COMPUTATIONAL LOAD / HEAT

MARA Granbury operating envelope

Site power context~300 MW
2025 companywide ASIC proxy~228.8 MW
300 MW heat equivalent~1,024 MMBtu/h
228.8 MW heat equivalent~781 MMBtu/h
Site meter / PUE / curtailmentUNKNOWN

CALCULATED / PROXY

Electrical input ultimately becomes heat, but site-specific metering and PUE remain separate evidence targets.

PROJECT PATRIOT / KNOX

Future-load instrument

Campus scale~2,000 acres
Turbine permit configuration8 × ~114 MW
Linear generators87 × ~0.23 MW
Approx. permitted generation~932 MW
Initial fill / makeup sourceUNKNOWN
OPEN EVIDENCE FAULT: closed-loop claims do not establish initial fill source, makeup volume, or actual withdrawal.
SCENARIO AVIONICS

Power → energy → heat, without pretending it is measured
