You need to do some reading. The 2 dams already exist so Snowy can run for a week without needing any pumped work to begin. Unlike a Battery, Pumped Hydro HAS Generators, so you are totally wrong. They will sell Electricity at night @20c and buy @10c to RENEW the Upper Dam making a 10c PROFIT as an example. There will be no need for Nukes as planned Pumped Hydro will cover that generation requirement. You are just being disengenuios. Bye.
