The potential of the 36 kV voltage level for distribution networks

The energy production from renewable energy sources and the accelerating trend of electrification are at the core of the energy transition. With a focus on the upcoming years, the transition aims to achieve low or zero carbon emissions, yet it expects a surge in electricity demand driven by the electrification of end-use consumption. Sustained by European regulations,this electrification is seen as the most effective means to accelerate the energy transition and decarbonisation, leading to enhanced efficiency, and reduced urban air pollution. However, these developments also pose challenges for the grid infrastructure and renewable energy deployment. The current layout of the distribution network faces the risk of collapse in the coming years due to the escalating electricity demand, particularly saturating the 20 kV main lines during peak load periods. Amidst these dynamics, the deployment of the new unified 36 kV voltage level also for the distribution network emerges as a promising solution for efficiently managing heavy loads, while effectively managing costs and minimising spatial requirements.
