 ### 100 MWe Model (Phase I)
 
-The 100 MWe model, with equivalent capacity to Phase I, has not yet been updated for the October 2026 Update.
+The case study also includes a 100 MWe model, `Fervo_Project_Cape-8`, with equivalent capacity to Phase I.
+Like the 500 MWe model, `Fervo_Project_Cape-8` represents a SOAK project and not the real-world Phase I implementation
+as built by Fervo. It is derived from `Fervo_Project_Cape-7` by reducing the number of production wells, shortening
+the construction period, scaling interconnection and transmission costs to 100 MWe, and resizing the debt fraction
+to meet the same minimum DSCR target.
+[Click here](https://gtp.scientificwebservices.com/geophires/?geophires-example-id=Fervo_Project_Cape-8) to view the
+100 MWe model in the GEOPHIRES web interface.
