Cost year of Cost Models

Cost year of Cost Models#

Some cost models are derived from literature and output costs (CapEx and OpEx) in a specific dollar-year. Some cost models require users to input the key cost information and the output costs are in the same cost year as the user-provided costs. For cost models with a built-in cost year, the cost year is not required as an input for the cost model. For cost models based on user-provided costs, the cost_year should be included in the tech_config for that technology.
