 # Example: SAM Single Owner PPA Economic Model: 400 MWe BICYCLE Comparison
 # This example is adapted from Fervo_Project_Cape-3, allowing for comparison between BICYCLE and SAM economic models.
 # Note that this example produces an unrealistically high IRR of ~60%. This is an artifact of using Fervo_Project_Cape-3's
-# BICYCLE parameters and assumptions as-is with the SAM Economic Model (such as starting electricity rate = $15 cents/kWh).
+# BICYCLE parameters and assumptions as-is with the SAM Economic Model (such as starting electricity rate = 15 cents/kWh).
 # See example_SAM-single-owner-PPA for parameters formulated with more refined assumptions appropriate for the
