PyPSA-PL: Modelling decarbonisation pathways for the Polish energy system

The Energy Policy of Poland until 2040 (PEP2040) does not take into account the ambitious goals of the EU’s climate policy and underestimates the pace of replacing fossil fuels with renewable energy sources. Therefore, in 2021, Instrat proposed an alternative to the PEP2040 power mix and conducted its own simulations of the National Electricity System using the PyPSA-PL model. To meet the current needs of public debate and to further raise the level of climate ambition in an evidence-based way, we continue to develop our modelling tool.

PyPSA-PL is an optimisation model based on the open Python library PyPSA and a dedicated compilation of data on the Polish energy system (including the in-house data from the PyPSA-PL fits into the global trend of open energy modelling – our tool, assumptions, and input data are publicly available. The model features high temporal resolution (8760 hours per year) and high granularity of representation of power-generating units. The model optimises the dispatch of installed capacities to ensure sufficient power supply at all times of the year while maintaining the appropriate reserve and dynamically taking into account cross-border flows of electricity. With PyPSA-PL, we answer research questions about the share of different fuels in the energy mix, the optimal investments in infrastructure, and the system costs of electricity generation. Currently, PyPSA-PL focuses on electricity, but eventually, we want to include other sectors such as heating, transport, or the hydrogen economy.
