OCTOBER 2015 WHAT IS PUMPED STORAGE?
Upper Reservoir
Pumping Mode Lower . During Off-Peak Reservoir . Wholesale prices at their lowest . Power is drawn from the grid to pump Powerhouse water from the lower to the upper reservoir
Upper Reservoir
Generating Mode Lower . During daily Peaks Reservoir
For personal use only use personal For . Wholesale prices at their highest Powerhouse . Water is released from the upper reservoir to the lower reservoir to generate electricity

. Solar and wind will have higher penetration in electricity market over the coming decade; leading to
. Increasing proportion of the overall generation mix being renewable sources
. Renewable generation increases volatility in the electricity Network
‒ Intermittency inherent to solar and wind, which are by nature relatively unpredictable
‒ Intermittent generation places a burden on power system operators in managing supply and demand
. In order to manage the intermittency issues and keep demand and supply in balance, storage capacity must also grow in line with renewable deployment
‒ Installation of large scale storage projects typically involve very long lead times
‒ Storage options need to be "in place" rather than play "catch up" to renewable developments
