3.6.2.2.3.Change of the Energy Cost
The change of energy cost indicator reflects potential possibility of the
sudden change of energy cost due to the economic crisis in the energy system.
It is usually result of the unexpected economic events which are related to the
market fluctuation and economic crisis. The Energy Cost Indicator is
measured in €/kWh.
Resilience Index due to sudden change of energy cost will be
