Electrolysers, grid tariffs and the electricity system

Electrolysers play an important role in the future CO2-free energy system. The Dutch government aims to achieve 4 GW of electrolysis in the Netherlands by 2030 and 8 GW by 2032. There are two major uncertainties in achieving this aim.
First of all, it is difficult to achieve a balanced business case for electrolysers, partly due to the rising grid costs of electricity.
Secondly, there is grid congestion, which often prevents access to the grid with a fixed transmission charge.

In this study, we suggest adjustments to the structure of grid tariffs. These may lead to:

  • stronger location management
  • more efficient utilisation of the electricity grid
  • improved consistency of tariffs to the grid costs generated by electrolysers
