The database of cost assumptions is retrieved from the repository
PyPSA/technology-data and then
resources/costs.csv. Cost assumptions of previous PyPSA-Eur
versions can be restored by setting in the
config.yaml provides options to choose a reference year (
costs: year:) and use a specific version of the repository
It includes cost assumptions for all included technologies for specific years from various sources, namely for
- discount rate,
- investment (CAPEX),
- fixed operation and maintenance (FOM),
- variable operation and maintenance (VOM),
- fuel costs,
- efficiency, and
- carbon-dioxide intensity.
The given overnight capital costs are annualised to net present costs with a discount rate of \(r\) over the economic lifetime \(n\) using the annuity factor
Based on the parameters above the
capital_cost of the system components are calculated.
Modifying Cost Assumptions¶
To change cost assumptions in more detail, modify cost assumptions directly in
resources/costs.csv as this is not yet supported through the config file.
You can also build multiple different cost databases. Make a renamed copy of
data/costs-optimistic.csv) and set the variable
COSTS=data/costs-optimistic.csv in the
