 | Maximum Net Electricity Generation   | {{ max_net_generation_mwe}} MW | | |
 | Maximum Total Electricity Generation | {{ max_total_generation_mwe }} MW | Upper bound: 600 MW  | Combined nameplate capacity of 10×60 MWe Gen 2 ORCs. A total of 8×60 MWe Gen 2 ORCs have been announced for Phase II; 3 from Turboden and 5 from Baker Hughes (Turboden, 2025; Jacobs, 2025). This equates to 480 MW gross capacity for Phase II's 400 MW net capacity. An equivalent SOAK 500 MW project would therefore require 10 Gen 2 ORC units. (Note that the modular Gen 2 ORCs are not individually modeled in this case study, and are assumed to be combined into a single power plant.) |

 | Injection Pumping Parasitic Load <br/> ({Average Pumping Power}/{Average Total Electricity Generation}) | {{ parasitic_loss_pct ~ '%' }}  | Upper bound: 16.7% | The Phase II procurement strategy (480 MW gross / 400 MW net) implies a design ceiling of 16.7% for total on-site consumption (including injection pumping). Current SOAK targets for parasitic consumption range from 15–20%, reflecting a planned reduction from the ~25–30% observed in Phase I operations (Norbeck, 2026). |
