While the Gringarten model accurately predicts the reservoir's thermal drawdown, translating that thermal energy into net electrical power introduces additional variables.

Users comparing GEOPHIRES power production estimates to Fervo's published net generation may notice discrepancies.

These arise from fundamental differences between an idealized techno-economic model and a real-world, non-commercial operational plant:
