Storage can provide similar start-up power to larger power plants, if the storage system is suitably sited and there is a clear transmission path to the power plant from the storage system''s location. Storage system size range: 5–50 MW Target discharge duration range: 15 minutes to 1 hour Minimum cycles/year: 10–20.

A pump curve is a graphical representation of a centrifugal pump''s performance characteristics. It shows the relationship between the flow rate (Q), head (H), and power consumption (P) of a pump at different operating points. The pump curve is generated by testing the pump in a laboratory and plotting the data on a graph.

It was, therefore, agreed at the 20th ExCo meeting (London, UK) that, in a series of studies, the cost curve data would be assembled for all of the potential storage options on a common basis. It was further agreed that the best approach to develop this cost information was to co-operate with regional research activities that were undertaking similar activities.
