9.3.5. Commodities¶
Input
Input commodities are the commodities consumed by each technology. They are defined in a csv file which describes the commodity inputs to each technology, calculated per unit of technology activity, Where the unit is defined by the user (e.g. petajoules).
Output
Output commodities are the commodities produced by each technology. They are defined in a csv file which describes the commodity outputs from each technology, defined per unit of technology activity. Emissions, such as CO2 (produced from fuel combustion and reactions), CH4, N2O, F-gases, can also be accounted for in this file.
General features
To illustrate the data required for a generic technology in MUSE, the electric boiler technology is used as an example. The commodity flow for the electric boiler, capable to cover space heating and water heating energy service demands.
The table below shows the basic data requirements for a typical technology, the electric boiler.¶
Below it is shown the generic structure of the input commodity file for the electric heater.

- ProcessName
represents the technology ID and needs to be consistent across all the data inputs.
- RegionName
represents the region ID and needs to be consistent across all the data inputs.
- Time
represents the period of the simulation to which the value applies; it needs to contain at least the base year of the simulation.
- Level
characterises either a fixed or a flexible input type the following columns should contain the list of commodities the row.
- Unit
reports the unit in which the technology consumption is defined; it is for the user internal reference only.
The input data has to be provided for the base year. Additional years within the time framework of the overall simulation can be defined. In this case, MUSE would interpolate the values between the provided periods and assume a constant value afterwards. The additional years at which input data for input/output commodities, are defined needs to equal for Techno-data and Techno-data Timeslices.
Interpolation is activated only if the feature interpolation_mode = ‘Active’ is defined in the TOML file.
