================ ================
* Add an efficiency factor of 88.55% to offshore wind capacity factors * new feature
as a proxy for wake losses. More rigorous modelling is `planned <https://github.com/PyPSA/pypsa-eur/issues/153>`_
[`#277 <https://github.com/PyPSA/pypsa-eur/pull/277>`_].
* The default deployment density of AC- and DC-connected offshore wind capacity is reduced from 3 MW/sqkm PyPSA-Eur 0.5.0 (26th July 2022)
to a more conservative estimate of 2 MW/sqkm [`#280 <https://github.com/PyPSA/pypsa-eur/pull/280>`_]. =====================================
* Following discussion in `#285 <https://github.com/PyPSA/pypsa-eur/issues/285>`_ we have disabled the **New Features**
correction factor for solar PV capacity factors by default while satellite data is used.
A correction factor of 0.854337 is recommended if reanalysis data like ERA5 is used.
* Resource definitions for memory usage now follow `Snakemake standard resource definition <https://snakemake.readthedocs.io/en/stable/snakefiles/rules.html#standard-resources>`_ ``mem_mb`` rather than ``mem``.
* Network building is made deterministic by supplying a fixed random state to network clustering routines.
* New network topology extracted from the ENTSO-E interactive map. * New network topology extracted from the ENTSO-E interactive map.
* The unused argument ``simple_hvdc_costs`` in :mod:`add_electricity` was removed. * Added existing renewable capacities for all countries based on IRENA
statistics (IRENASTAT) using new ``powerplantmatching`` version:
* Iterative solving with impedance updates is skipped if there are no expandable lines.
* Switch from Germany to Belgium for continuous integration and tutorial to save resources.
* Use updated SARAH-2 and ERA5 cutouts with slightly wider scope to east and additional variables.

* old: ``estimate_renewable_capacities_from_capacity_stats`` * old: ``estimate_renewable_capacities_from_capacity_stats``
* new: ``estimate_renewable_capacities`` * new: ``estimate_renewable_capacities``
* The estimation is endabled by setting the subkey ``enable`` to ``True``. * The estimation is endabled by setting the subkey ``enable`` to ``True``.

* The list of renewables provided by the OPSD database can be used as a basis, using the tag ``from_opsd: True``. This adds the renewables from the database and fills up the missing capacities with the heuristic distribution. ``2020``)
* Uniform expansion limit of renewable build-up based on existing capacities can be configured using ``expansion_limit`` option * The list of renewables provided by the OPSD database can be used as a basis,
(default: ``false``; limited to determined renewable potentials) using the tag ``from_opsd: True``. This adds the renewables from the

distribution.
* Uniform expansion limit of renewable build-up based on existing capacities
can be configured using ``expansion_limit`` option (default: ``false``;
limited to determined renewable potentials)
* Distribution of country-level capacities proportional to maximum annual
energy yield for each bus region
* The config key ``renewable_capacities_from_OPSD`` is deprecated and was moved
under the section, ``estimate_renewable_capacities``. To enable it, set
``from_opsd`` to `True`.
* The config key ``renewable_capacities_from_OPSD`` is deprecated and was moved under the section, ``estimate_renewable_capacities``. To enable it, set ``from_opsd`` to `True`. * Add operational reserve margin constraint analogous to `GenX implementation
<https://genxproject.github.io/GenX/dev/core/#Reserves>`_. Can be activated
with config setting ``electricity: operational_reserve:``.
* Add operational reserve margin constraint analogous to `GenX implementation <https://genxproject.github.io/GenX/dev/core/#Reserves>`_. * Implement country-specific Energy Availability Factors (EAFs) for nuclear
Can be activated with config setting ``electricity: operational_reserve:``. power plants based on IAEA 2018-2020 reported country averages. These are
specified ``data/nuclear_p_max_pu.csv`` and translate to static ``p_max_pu``
values.
* Add function to add global constraint on use of gas in :mod:`prepare_network`. This can be activated by including the keyword ``CH4L`` in the ``{opts}`` wildcard which enforces the limit set in ``electricity: gaslimit:`` given in MWh thermal. Alternatively, it is possible to append a number in the `{opts}` wildcard, e.g. `CH4L200` which limits the gas use to 200 TWh thermal. * Add function to add global constraint on use of gas in :mod:`prepare_network`.
This can be activated by including the keyword ``CH4L`` in the ``{opts}``
wildcard which enforces the limit set in ``electricity: gaslimit:`` given in
MWh thermal. Alternatively, it is possible to append a number in the `{opts}`
wildcard, e.g. `CH4L200` which limits the gas use to 200 TWh thermal.
* A new section ``conventional`` was added to the config file. This section contains configurations for conventional carriers. * Add option to alter marginal costs of a carrier through `{opts}` wildcard:
`<carrier>+m<factor>`, e.g. `gas+m2.5`, will multiply the default marginal
cost for gas by factor 2.5.
* Add configuration option to implement arbitrary generator attributes for conventional generation technologies. * Hierarchical clustering was introduced. Distance metric is calculated from
renewable potentials on hourly (feature entry ends with `-time`) or annual
(feature entry in config end with `-cap`) values.
* Implement country-specific Energy Availability Factors (EAFs) for nuclear power plants based on IAEA 2018-2020 reported country averages. These are specified ``data/nuclear_p_max_pu.csv`` and translate to static ``p_max_pu`` values. * Techno-economic parameters of technologies (e.g. costs and efficiencies) will
now be retrieved from a separate repository `PyPSA/technology-data
<https://github.com/pypsa/technology-data>`_ that collects assumptions from a
variety of sources. It is activated by default with ``enable:
retrieve_cost_data: true`` and controlled with ``costs: year:`` and ``costs:
version:``. The location of this data changed from ``data/costs.csv`` to
``resources/costs.csv`` [`#184
<https://github.com/PyPSA/pypsa-eur/pull/184>`_].
* The powerplants that have been shut down before 2021 are filtered out. * A new section ``conventional`` was added to the config file. This section
contains configurations for conventional carriers.
* ``powerplantmatching>=0.5.1`` is now required for ``IRENASTATS``. * Add configuration option to implement arbitrary generator attributes for
conventional generation technologies.
* The inclusion of renewable carriers is now specified in the config entry ``renewable_carriers``. Before this was done by commenting/uncommenting sub-sections in the `renewable` config section. * Add option to set CO2 emission prices through `{opts}` wildcard: `Ep<number>`,
e.g. `Ep180`, will set the EUR/tCO2 price.
* Now, all carriers that should be extendable have to be listed in the config entry ``extendable_carriers``. Before, renewable carriers were always set to be extendable. For backwards compatibility, the workflow is still looking at the listed carriers under the ``renewable`` key. In the future, all of them have to be listed under ``extendable_carriers``. **Changes**

<https://github.com/PyPSA/pypsa-eur/pull/277>`_].
* Listing conventional carriers in ``extendable_carriers`` but not in ``conventional_carriers``, sets the corresponding conventional power plants as extendable without a lower capacity bound of today's capacities. * Following discussion in `#285
<https://github.com/PyPSA/pypsa-eur/issues/285>`_ we have disabled the
correction factor for solar PV capacity factors by default while satellite
data is used. A correction factor of 0.854337 is recommended if reanalysis

* The ``build_year`` and ``lifetime`` column are now defined for conventional power plants. * The ``build_year`` and ``lifetime`` column are now defined for conventional
power plants.

removed.
* Switch from Germany to Belgium for continuous integration and tutorial to save
resources.
