Where do we find the massive amounts of flexibility, which is needed to keep electricity grids stable, when the input of intermittent renewables is rising? First of all, we searched for large industrial consumers and producers of energy in our harbour areas, trying to identify sources of flexibility in their operations.
Demand side flexibility. Actions voluntarily taken by a consumer to adjust the amount or timing of his energy consumption. Some installations can shift non-critical activities over time, other devices can store energy for later use. This demand side flexibility can be employed by grid operators and balancing responsible parties to maintain the equilibrium in the power grid.
