power and process heat co-generation CSP solar plant for power and desalination

Hi,
I want to study different scenarios for solar thermal desalination. Usually, thermal desalination systems extracting low-pressure steam from the power plant's turbine to operate the desalination system in a co-generation scheme.
Another scenario to compare is to use direct steam from the CSP-heat system to operate the thermal desalination systems.
I cannot find the page to specify the steam extraction conditions in the power cycle. Also, how the Levelized cost of this steam can be evaluated?
Thank you for your support.

Hi Hassan,

SAM's Industrial Process Heat (IPH) models calculate a "levelized cost of heat" They assume that the field heat transfer fluid (HTF) is delivered to a heat exchanger that collects heat for the application. You can use the time series output of the solar field (output variables with names that begin with "Field..." to determine properties of the HTF.

For more, see the IPH video here:
