The use of highly predictable tidal energy and associated technologies can contribute to the accurate sizing of the components. 250 MW of storage would allow the system to absorb some 290 GWh, which would otherwise be cut due to the grid line limit. The curtailment rate is reduced from 13% to 1% with storage support.
