The real Snowy Hydro-electric Scheme catches and stores water, uses it to generate reliable electricity, and then controls and releases that water for irrigation and other uses. It supplies both electricity and water.
Snowy 2 is a fraud – it provides ZERO additional supplies of water or electricity. In fact it will consume some of each. It will be a giant expensive battery propping up a grid which is becoming increasingly unstable because of the growing amount of unreliable weather-dependent wind and solar power.
