Electricity-based technologies should replace fossil fuels in heat production and transport in the near future. However, these technologies are at an economic disadvantage compared to conventional technologies, among other reasons, due to the EEG levy and the effect this has of increasing the electricity price. This is hindering the decarbonization of these sectors. In a research project, Fraunhofer ISI analyzed how redesigning the EEG levy and electricity tax affects the competitiveness of electricity-based technologies, and what financial impacts this could have on transport, industry, households and the service sector. The final report shows that some technologies require less financial support, others more. It therefore seems to make sense to apply individual, financial support depending on the sector and technology.
