A project funded by the World Bank, with the key objective to develop an energy system model and examine decarbonisation pathways for the energy system of each of the WB6 countries by 2050. The TIMES model generator will be used for the development of the regional model. The project will analyse the necessary investments in the energy sector to achieve a carbon-neutral economy by 2050 in each country, compared to the policies and measures which are currently planned. Furthermore, an impact analysis will be performed of the introduction of carbon pricing according to the EU-ETS in the short and in the long term towards 2050.
