What each input means

Reservoir Temperature
Temperature of the geothermal reservoir fluid.
Production Flow Rate
Flow rate per production well in liters per second.
Reinjection Temperature
Temperature of fluid reinjected into the reservoir.
Turbine Efficiency
Turbine isentropic efficiency.
Parasitic Load
Power consumed by pumps, fans, and plant auxiliaries.
Production Wells
Number of production wells.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Reservoir Temperature = 200, Production Flow Rate = 80, Reinjection Temperature = 70, Turbine Efficiency = 70 = 6 input(s) provided
  2. Calculate Net Power per Well
    Net Power per Well
    7.12 = 7.12
  3. Calculate Total Plant Output
    Total Plant Output
    21.35 = 21.35
  4. Calculate Thermal Power per Well
    Thermal Power per Well
    43.53 = 43.53
  5. Calculate Annual Output per Well
    Annual Output per Well
    59227 = 59227
