This section defines variables and indicators related to characteristics and specifications of (energy) technologies including power plants, transmission lines and pipelines.
Note that there is no clear distinction whether a variable defined in this section is an assumption (input) or a model result (output) - this depends on the context of the modelling framework. For example, the "installed capacity" of a power plant may be an exogenous assumption in a (short-term) power-system dispatch model or a result from a long-term investment model. The respective use case should be clearly specified in the model documentation.
Explanations of the different categories and the structures of the variables are given below. See technologies.yaml for the full codelist.
Variables for the installed capacity of (energy) production/generation or transmission should follow the structure below.
Capacity|{Fuel}Capacity|{Fuel}|{Specification}Capacity|{Fuel}|{Specification}|{Identifier Of A Specific Power Plant}
Variables for the overnight capital cost for new construction of power plants or tranmission lines should follow the structure below.
Capital Cost|{Fuel}|{Specification}Capital Cost|{Fuel}|{Specification}|{Identifier Of A Specific Power Plant}
Note that it usually does not make sense to report capital costs
at a more aggregate level (i.e., Capital Cost|{Fuel}).
Variables for the expenditure for new construction of power plants or tranmission lines should follow the structure below.
Investment|{Type}Investment|{Type}|{Fuel}Investment|{Type}|{Fuel}|{Specification}
