Demand for electricity

Choosing the direction of energy industry development will have a major impact on the demand for electricity. In addition to economic development, electricity demand will be affected in particular by the development of electromobility and the utilization of electricity to replace fossil fuels, particularly domestic brown coal. The analysis shows that the Czech Republic would reach the highest demand for electricity in case of meeting Roadmap 2050 targets by focusing on low-emission energy sources. On the other hand, the Czech Republic would have the lowest demand for electricity in case of meeting the Roadmap 2050 targets by using the maximum technically feasible savings. Both EU case studies include the assumption of a high transition to electromobility, which is approximately double the level of the Conceptual case study for both other case studies. In particular, electromobility will cause the demand for electricity not to decrease after 2030 in the EU – Energy Savings case study, but even in this case study, electricity demand will significantly increase.

Medium-term horizon

  • In the medium-term horizon, the development of electricity demand differs according to the case studies significantly, mainly due to the differences in the rate of achieved energy savings and the rate of electromobility development.
  • In 2030, the domestic net consumption will amount to 72 TWh including electromobility in the Conceptual case study (increase by 18% compared to 2016), to 67 TWh in the EU – Energy Savings case study and to 75 TWh in the EU – Low-Emission Sources case study.


Long-term horizon

  • In the long-term horizon, demand in the case studies is already highly differentiated, while the Conceptual case study is approximately in-between the other ones.
  • In 2050, the domestic net consumption will amount to 82TWh including electromobility in the Conceptual case study (increase by 34% compared to 2016), to 73TWh in the EU – Energy Savings case study and to 92TWh in the EU – Low-Emission Sources case study.
  • The expected growth of electromobility will have a significant impact; high utilization of electromobility is becoming more likely, as practical technical designs are presented. In the EU case studies, where emphasis was placed on reducing greenhouse gas emissions and pollutants in general, the demand for the electromobility is to be around 12TWh in 2050; in the Conceptual case study, where there is a certain trade-off in case of emissions, it is only about 6TWh.
  • Case studies differ significantly in the amount of electricity produced at low-voltage and high-voltage levels. According to the Conceptual and the EU – Energy Savings case studies, this production amounts to about 20TWh in 2050, however, it amounts to approximately 37.2TWh in the EU – Low-Emission Sources case study.
  • Generation at the lowest low-voltage distribution level will reduce the amount of grid supplied power and, moreover, increase the amount of unmeasured consumption. In the case of the Conceptual case study, unmeasured consumption may amount to about 2TWh and up to approximately 7.2TWh in the case of the EU – Low-Emission Sources case study.
