Demand for electricity

At the level of energy demand outlook, the presented case studies anticipate the same economic and demographic development. In the mid-term horizon, the Czech Republic is expected to experience higher economic and societal advancement, albeit not as pronounced as in the period from 2014 to 2017. Eventually, gradual convergence of the Czech economic level towards the EU average is expected over the long-term. Product growth will be a significant invariable positive influence over the increase in both electricity and gas demand. Considering current projections, demographic development in the Czech Republic will be moderately affected by migration into and within Europe.

The case studies assume different levels of savings and different utilization of energy in new areas. The Renewable and Gas case studies presume a higher pace in achieving energy savings by a third compared to the Conceptual case study. Differences in the utilization of electricity and gas in new consumption areas are more diverse – the main categories showing more substantial differences include electromobility, CNG/LNG utilization in transport, replacement of both steam and graded brown coal, and partial deviation from district heating.

In terms of the aforementioned three case studies, electricity demand at the level of net consumption is not significantly differentiated, although individual demand components substantially differ from case to case. In addition to general economic development, electricity demand will be influenced by other important factors such as the development of electromobility, use of electricity for fossil fuel replacement and the level of achieved energy savings. Domestic net consumption development is shown in the following figure.

Mid-term horizon (up to 2030)

  • In the mid-term horizon, there is no significant difference in the development of electricity demand as presented by individual case study, which is due to the compensation of effects of diverse level of savings and the diverse rate of electromobility development.
  • The Conceptual case study envisages domestic net consumption, including electromobility, to be at 72 TWh in 2030, which an increase of approximately 16% compared to 2017; in the same category, this is 70 TWh for the Renewable case study and 69 TWh for the Gas case study.


Long-term horizon (up to 2050)

  • Development of the three above-mentioned case studies defines the increase in electricity demand at the level of net consumption within the range of 25–33% by 2050 compared to 2018.
  • In the long run, the variations in the level of demand are differentiated a little more but, again, the effect of diverse level of savings and the diverse rate of electromobility development is compensated.
  • The Conceptual case study envisages domestic net consumption, including electromobility, to be at 83 TWh in 2050, which an increase of approximately 33% compared to 2017; in the same category, this is 80 TWh for the Renewable case study and 78 TWh for the Gas case study.
  • The application of electromobility will represent a major growth factor. The likelihood that electromobility will be the most prevalent type of automobile technology (approximately 35 to 50% of all standard passenger vehicles) has increased since last year.
  • In the Renewable and Gas case studies which place more emphasis on new EU policies, the electromobility sector demand is predicted to be at approximately 12 TWh in 2050, while this figure is only 6 TWh in the Conceptual case study.
  • These case studies differ significantly with regard to the amount of electricity generated at LV grid levels. This type of generation approaches 4.7 TWh in 2050 in the Conceptual case study, 19 TWh in the Renewable case study and 5.4 TWh in the Gas case study.
  • Generation at the lowest distribution level of low voltage – at the offtake point – will lower the volume of grid-supplied electricity and increase the volume of undeclared consumption. In the case of the Conceptual case study, undeclared consumption can reach approximately 2 TWh and up to 9 TWh in the Renewable case study.
