Configuration

PyPSA-Eur has several configuration options which are documented in this section.

Configuration Files

Any PyPSA-Eur configuration can be set in a .yaml file. The default configurations config/config.default.yaml and config/plotting.default.yaml are maintained in the repository and cover all the options that are used/ can be set.

To pass your own configuration, you can create a new file, e.g. my_config.yaml, and specify the options you want to change. They will override the default settings and options which are not set, will be inherited from the defaults above.

Another way is to use the config/config.yaml file, which does not exist in the repository and is also not tracked by git. But snakemake will always use this file if it exists. This way you can run snakemake with a custom config without having to specify the config file each time.

Configuration order of precedence is as follows: 1. Command line options specified with --config (optional) 2. Custom configuration file specified with --configfile (optional) 3. The config/config.yaml file (optional) 4. The default configuration files config/config.default.yaml and config/plotting.default.yaml

To use your custom configuration file, you need to pass it to the snakemake command using the --configfile option:

$ snakemake -call --configfile my_config.yaml

Warning

In a previous version of PyPSA-Eur (<=2025.04.0), a full copy of the created config was stored in the config/config.yaml file. This is no longer the case. If the file exists, snakemake will use it, but no new copy will be created.

Top-level configuration

“Remote” indicates the address of a server used for data exchange, often for clusters and data pushing/pulling.

version: v2025.04.0
tutorial: false

logging:
  level: INFO
  format: '%(levelname)s:%(name)s:%(message)s'

  ssh: ""
  path: ""

	Unit	Values	Description
version	–	0.x.x	Version of PyPSA-Eur. Descriptive only.
tutorial	bool	{true, false}	Switch to retrieve the tutorial data set instead of the full data set.
logging
– level	–	Any of {‘INFO’, ‘WARNING’, ‘ERROR’}	Restrict console outputs to all infos, warning or errors only

– ssh	–		Optionally specify the SSH of a remote cluster to be synchronized.
– path	–		Optionally specify the file path within the remote cluster to be synchronized.

run

It is common conduct to analyse energy system optimisation models for multiple scenarios for a variety of reasons, e.g. assessing their sensitivity towards changing the temporal and/or geographical resolution or investigating how investment changes as more ambitious greenhouse-gas emission reduction targets are applied.

The run section is used for running and storing scenarios with different configurations which are not covered by Wildcards. It determines the path at which resources, networks and results are stored. Therefore the user can run different configurations within the same directory. If a run with a non-empty name should use cutouts shared across runs, set shared_cutouts to true.

run:
  prefix: ""
  name: ""
  scenarios:
    enable: false
    file: config/scenarios.yaml
  disable_progressbar: false
  shared_resources:
    policy: false
    exclude: []
  shared_cutouts: true
  use_shadow_directory: false

	Unit	Values	Description
name	–	str/list	Specify a name for your run. Results will be stored under this name. If scenario: enable: is set to true, the name must contain a subset of scenario names defined in scenario: file:. If the name is ‘all’, all defined scenarios will be run.
prefix	–	str	Prefix for the run name which is used as a top-layer directory name in the results and resources folders.
scenarios
– enable	bool	{true, false}	Switch to select whether workflow should generate scenarios based on file.
– file	str		Path to the scenario yaml file. The scenario file contains config overrides for each scenario. In order to be taken account, run: scenarios has to be set to true and run: name has to be a subset of top level keys given in the scenario file. In order to automatically create a scenario.yaml file based on a combination of settings, alter and use the config/create_scenarios.py script in the config directory.
disable_progressbar	bool	{true, false}	Switch to select whether progressbar should be disabled.
shared_resources
– policy	bool/str		Boolean switch to select whether resources should be shared across runs. If a string is passed, this is used as a subdirectory name for shared resources. If set to ‘base’, only resources before creating the elec.nc file are shared.
– exclude	str	For the case shared_resources=base, specify additional files that should not be shared across runs.
shared_cutouts	bool	{true, false}	Switch to select whether cutouts should be shared across runs.
use_shadow_directory	bool	{true, false}	Set to true (default) if snakemake shadow directories (shallow) should be used. Set to false if problems occcur.

foresight

foresight: overnight

	Unit	Values	Description
foresight	string	{overnight, myopic, perfect}	See Foresight Options for detail explanations.

Note

If you use myopic or perfect foresight, the planning horizon in The {planning_horizons} wildcard in scenario has to be set.

scenario

The scenario section is an extraordinary section of the config file that is strongly connected to the Wildcards and is designed to facilitate running multiple scenarios through a single command

# for electricity-only studies
$ snakemake -call solve_elec_networks

# for sector-coupling studies
$ snakemake -call solve_sector_networks

For each wildcard, a list of values is provided. The rule solve_all_elec_networks will trigger the rules for creating results/networks/base_s_{clusters}_elec_{opts}.nc for all combinations of the provided wildcard values as defined by Python’s itertools.product(…) function that snakemake’s expand(…) function uses.

An exemplary dependency graph (starting from the simplification rules) then looks like this:

scenario:
  clusters:
  - 39
  - 128
  - 256
  opts:
  - ''
  sector_opts:
  - ''
  planning_horizons:
  # - 2020
  # - 2030
  # - 2040
  - 2050

The first part can be v (for setting a limit on line volume) or c (for setting a limit on line cost). The second part can be opt or a float bigger than one (e.g. 1.25). If opt is chosen line expansion is optimised according to its capital cost (where the choice v only considers overhead costs for HVDC transmission lines, while c uses more accurate costs distinguishing between overhead and underwater sections and including inverter pairs). The setting v1.25 will limit the total volume of line expansion to 25% of currently installed capacities weighted by individual line lengths. The setting c1.25 will allow to build a transmission network that costs no more than 25 % more than the current system.

– curtailment_mode	bool/float	{‘true’,’false’}	Fixes the dispatch profiles of generators with time-varying p_max_pu by setting p_min_pu = p_max_pu and adds an auxiliary curtailment generator (with negative sign to absorb excess power) at every AC bus. This can speed up the solving process as the curtailment decision is aggregated into a single generator per region. Defaults to false.
– noisy_costs	bool	{‘true’,’false’}	Add random noise to marginal cost of generators by \(\mathcal{U}(0.009,0,011)\) and capital cost of lines and links by \(\mathcal{U}(0.09,0,11)\).
– skip_iterations	bool	{‘true’,’false’}	Skip iterating, do not update impedances of branches. Defaults to true.
– rolling_horizon	bool	{‘true’,’false’}	Switch for rule solve_operations_network whether to optimize the network in a rolling horizon manner, where the snapshot range is split into slices of size horizon which are solved consecutively. This setting has currently no effect on sector-coupled networks.
– seed	–	int	Random seed for increased deterministic behaviour.
– custom_extra_functionality	–	str	Path to a Python file with custom extra functionality code to be injected into the solving rules of the workflow relative to rules directory.
– io_api	string	{‘lp’,’mps’,’direct’}	Passed to linopy and determines the API used to communicate with the solver. With the 'lp' and 'mps' options linopy passes a file to the solver; with the 'direct' option (only supported for HIGHS and Gurobi) linopy uses an in-memory python API resulting in better performance.
– track_iterations	bool	{‘true’,’false’}	Flag whether to store the intermediate branch capacities and objective function values are recorded for each iteration in network.lines['s_nom_opt_X'] (where X labels the iteration)
– min_iterations	–	int	Minimum number of solving iterations in between which resistance and reactence (x/r) are updated for branches according to s_nom_opt of the previous run.
– max_iterations	–	int	Maximum number of solving iterations in between which resistance and reactence (x/r) are updated for branches according to s_nom_opt of the previous run.
– transmission_losses	int	[0-9]	Add piecewise linear approximation of transmission losses based on n tangents. Defaults to 0, which means losses are ignored.
– linearized_unit_commitment	bool	{‘true’,’false’}	Whether to optimise using the linearized unit commitment formulation.
– horizon	–	int	Number of snapshots to consider in each iteration. Defaults to 100.
– post_discretization
– – enable	bool	{‘true’,’false’}	Switch to enable post-discretization of the network. Disabled by default.
– – line_unit_size	MW	float	Discrete unit size of lines in MW.
– – line_threshold		float	The threshold relative to the discrete line unit size beyond which to round up to the next unit.
– – link_unit_size	MW	float	Discrete unit size of links in MW by carrier (given in dictionary style).
– – – {carrier}
– – link_threshold		float	The threshold relative to the discrete link unit size beyond which to round up to the next unit by carrier (given in dictionary style).
– – – {carrier}
– – fractional_last_unit_size	bool	{‘true’,’false’}	When true, links and lines can be built up to p_nom_max. When false, they can only be built up to a multiple of the unit size.
– model_kwargs
– – solver_dir	str	‘/tmp’’	Absolute path to the directory where linopy saves files.
– keep_files	bool	False	Whether to keep LPs and MPS files after solving.
agg_p_nom_limits			Configure per carrier generator nominal capacity constraints for individual countries if 'CCL' is in {opts} wildcard.
– agg_offwind	bool	{‘true’,’false’}	Aggregate together all the types of offwind when writing the constraint. Default is false.
– agg_solar	bool	{‘true’,’false’}	Aggregate together all the types of electric solar when writing the constraint. Default is false.
– include_existing	bool	{‘true’,’false’}	Take existing capacities into account when writing the constraint. Default is false.
– file	file	path	Reference to .csv file specifying per carrier generator nominal capacity constraints for individual countries and planning horizons. Defaults to data/agg_p_nom_minmax.csv.
constraints
– CCL	bool	{‘true’,’false’}	Add minimum and maximum levels of generator nominal capacity per carrier for individual countries. These can be specified in the file linked at electricity: agg_p_nom_limits in the configuration. File defaults to data/agg_p_nom_minmax.csv.
– EQ	bool/string	{‘false’,`n(c| )``; i.e. 0.5-0.7c}	Require each country or node to on average produce a minimal share of its total consumption itself. Example: EQ0.5c demands each country to produce on average at least 50% of its consumption; EQ0.5 demands each node to produce on average at least 50% of its consumption.
– BAU	bool	{‘true’,’false’}	Add a per-carrier minimal overall capacity; i.e. at least 40GW of OCGT in Europe; configured in electricity: BAU_mincapacities
– SAFE	bool	{‘true’,’false’}	Add a capacity reserve margin of a certain fraction above the peak demand to which renewable generators and storage do not contribute. Ignores network.
solver
– name	–	One of {‘gurobi’, ‘cplex’, ‘highs’, ‘cbc’, ‘glpk’}; potentially more possible	Solver to use for optimisation problems in the workflow; e.g. clustering and linear optimal power flow.
– options	–	Key listed under solver_options.	Link to specific parameter settings.
solver_options		dict	Dictionaries with solver-specific parameter settings.
mem	MB	int	Estimated maximum memory requirement for solving networks.
mem_logging_frequency	s	int	Interval in seconds at which memory usage is logged.
