This case study – example name: `Fervo_Project_Cape-4` – is modeled
44
on Fervo Cape Station with
55
its [announced upsizing from 400 MW to 500 MW](https://fervoenergy.com/fervo-energy-announces-31-mw-power-purchase-agreement-with-shell-energy/),
66
using a combination of publicly available data, extrapolations, and estimates. The tables below highlight key input
77
assumptions and
88
comparison of results with reference values.

| Flow Rate per Production Well | 107 kg/s | Maximum flow rate achieved at Cape Station per https://www.businesswire.com/news/home/20240910997008/en/Fervo-Energys-Record-Breaking-Production-Results-Showcase-Rapid-Scale-Up-of-Enhanced-Geothermal. The announced increased casing diameter implies higher flow rates. |
