flexibility (demand side response)

flexibility describes the increasing or decreasing of power output of operating technologies and energy sources and/or shifting the electricity consumption of the delivery point through battery storage in real time in order to reduce the load on the transmission system. Flexibility helps to balance peaks (peak shaving) and shift the load (load shifting) of the transmission system and results in additional income for the delivery point from the provision of Non-certified Ancillary Services. Flexibility plays an important role in the transition to low-carbon energy by including a higher share of renewable energy sources.
