         # Climate Option 1 (Default): Use levelized emissions data from NREL's Cambium database by specifying the following fields:
-        cambium_scenario::String = "Mid-case", # Cambium Scenario for evolution of electricity sector (see Cambium documentation for descriptions). 
+        cambium_scenario::String = "Mid-case", # Cambium Scenario for evolution of electricity sector (see ELectricUtility docsting for options and/or Cambium docs for descriptions).
