Similar to the technology used in the Snowy River system on the East coast, mini-pumped hydro is a form of pumped hydro.
Just like traditional hydro-electric systems, water is pumped from a lower area to a higher area, the ‘storing’ of water in the higher dam acts as a battery
When power is needed, the water is released through a generator to create power for distribution.
However, ‘mini’ means it happens on a much smaller scale.
For example, the new Walpole mini-pumped hydro system has a capacity of 1.5MW, much smaller than a large-scale energy generator. It only requires an incline or drop of around 90 metres, supported by a dam area of around 2 hectares, smaller than many of the dams used for farming in the region.
This makes it the smallest edge-of-grid mini-pumped hydro system in the world, and a fascinating insight into how mini-pumped hydro will work, and the benefits it will bring.
