This episode is talking about “Challenges for the power sector: The need for changes”. The power sector is becoming more important than ever because it holds the key to decarbonization. A highly digitalized society cannot be maintained without stability in the power sector. Nevertheless, the power sector is currently facing several challenges which are not limited to a single country but are similar among many of the advanced economies. It is worth looking into actions that would be necessary and appropriate for all countries. Belief in the laissez-faire of the day-ahead market to resolve everything is becoming outdated. New policy interventions and systems are required.
