Reply With Quotethe idea isnt that silly
you pump the water up the hill only when you have excess power.
when you have a shortage of power, you use the built up water to spin the generators and produce power.

SubscriberYou would not believe what they are intending to do to supposedly get more out of the snowy scheme. They are going to pump water back up hill to run through the generators. So what you say? It will take 20% more power to pump the water than what power is produced. This also does not take into account the needs of irrigation. Talk about trying to pull a fast one over the public.

It works for peak electricity demand periods - it has been done out of the Shoalhaven River system in Kangaroo Valley since 1977. Shoalhaven Scheme - Wikipedia Pump it up hill overnight when the demand is low and run it back down the hill during times of high demand.

Nothing farcical about pumped hydro energy storage, it's been done all over the world including Australia. Cheap off peak power is used to pump up water when it's available and when peak demand occurs the hydro system can do it's bit to keep the lights on. The water isn't wasted, it's recycled. Instead of just using coal fired off peak power, systems like that can now use intermittent power like solar and wind.
The costs of expanding the Snowy scheme might be too high compared to other forms of storage though. Previous attempts to upgrade it have all been shelved because of that, no reason to believe a new study will show any different.

I thought snowfalls were decreasing over time so the only way the snowy scheme could be expanded would be to "recycle" the water back through the system? We already have the basis of a huge pumped hydro storage system. Why not adapt it to true pumped hydro storage and future proof it!

It's already being done in The Snowies.

When I visited a few years ago i learned that they also do cloud seeding. To promote more snowfall in winter months to fill the lakes for warmer months

Yep - I remember going on a tour through Talbingo (Tumut 3) power station when I was a kid. My parents had the dry cleaning business at Tumut at the time and one of my father's mates was an engineer with the Snowy Scheme, and he took us on a tour that included some areas that the general public usually did not get to see.
Three of the six generating units at Tumut 3 can operate as pumps, pumping water back up into the Talbingo Dam above the power station during "off peak" periods when demand is lower, providing energy "storage" for want of a better word. I believe that Tumut 3 was the first "pumped storage" hydro plant in Australia.
A bloody good idea if you ask me. The ability to do this, coupled with renewable energy sources (wind / solar & others) will go a long way towards meeting future power requirements. This type of energy storage CAN provide base load power on demand.
