Changelog

  • Switched to new secant based transmission losses from pypsa 1.1
  • Switched to weather year 2013
  • in 2030 use UBA data for industry and mobility
  • start myopic optimization in 2025
  • remove national CO2 sequestration limit for DE, because it was causing strange E-Fuel exports
  • enable H2 gas turbines in all countries
  • force H2 retrofit (for DE) only in 2045, instead of in 2035
  • split existing solar 50:50 between rooftop and utility (previously 0:100)
  • increase decentral discount rates to account for mix of residential and commercial sector
  • use ISE cost data for solar (DC costs instead of AC)
  • Minor fix for cluster weights
  • added 2 delay years to the offshore NEP, s.t. capacity in 2030 is ~20GW
  • improved script name modify_industry_demand -> modify_industry_production
  • excluded international shipping from DE-specific CO2 emisisons
  • improved land transport shares, and some RES constraints
  • disabled ptes before 2035
  • add function to limit cross border electricity flows, to comply with the 0.7 security margin and the 0.7 EU trade capacity goals
  • Added an option to source industry energy demand from UBA MWMS (Projektionsbericht 2025) for the years 2025-2035
  • renamed some scripts
  • Upstream: PyPSA-Eur adopted a new functionality for overwriting costs. PyPSA-DE follows this convention now. As a consequence, the costs:horizon:optimist/mean/pessimist is no longer available. Mean will be provided exclusively from now on. Also, the costs assumptions for onwind turbines changed sligthly. Furthermore, "costs:NEP_year:2021/2023" is no longer available, instead one of the custom_cost files for these NEP years provided in the data/pypsa-de folder has to be specified.
  • The ariadne-data folder has been moved and renamed to data/pypsa-de to conform with the syntax of scripts/pypsa-de
  • Bugfix: Enforce stricter power import limit to avoid that import from one country compensate from exports to another
  • Added the IIASA database to the repository and disabled re-downloading it by default.
  • Simplified IIASA database download, rename iiasa_database config section to pypsa-de
  • Updated technology-data to v0.13.4
  • Bugfix: Enforce stricter H2 derivative import limit to avoid that exports of one type of derivative compensate for imports of another
  • Added an option to source mobility demand from UBA MWMS (Projektionsbericht 2025) for the years 2025-2035
  • Renamed functions and script for exogenous mobility demand
  • Improved the transport demand data, added an option to source 2020 and 2025 data from AGEB instead of Aladin
  • Added a helper function to change the weather_year to build_scenario
  • Longer lifetime (40 years) is only applied to existing gas CHPs, not new ones. Added a new config entry existing_capacities:fill_value_gas_chp_lifetime
  • Bugfix: gas CHPs are extendable again
  • Simplified scenarion definition and made Mix the default scenario
  • 0.3: workflow is all public now, no longer requires credentials to internal data
  • Allowing myopic optimization until 2050
  • CHP plants located in onshore regions without district heating are represented as EOP plants
  • updating technology cost data to v0.11.0
  • add option for Offhsore NEP to delay projects by x years (CurPol and KN2045minus_WorstCase are delayed by one year)
  • Force onwind south by increasing minimum capacity and decreasing capacity per sqkm
  • Adjusting aviation demand (from Aladin) and emission accounting (only domestic aviation for national target)
  • Increase HVC_environment_sequestration_fraction from 0.1 to 0.6
  • Disallow HVC to air in DE
  • Restricting the maximum capacity of CurrentPolicies and minus scenarios to the 'uba Projektionsbericht'
  • Restricting Fischer Tropsch capacity addition with config[solving][limit_DE_FT_cap]
  • Except for Current Policies force a minimum of 5 GW of electrolysis capacity in Germany
  • limit the import/export limit to/from Germany
  • adjusting capacity factor of solar to match historic data
  • Rely on DEA investment costs for electrolysis
  • updated the Kernnetz to use latest data and operate it more flexible
  • added Italy with 3 additional nodes
  • adapted spatial distribution of district heating demand in Germany according to data from eGo^N project
  • add retrofit of gas turbines to H2, and H2 turbines
  • unravel gas bus and turn off gas network
  • fix the hydrogen import boundary condition
  • add primary oil bus and account for refinery emissions
  • added Changelog file
