HOW MUCH WILL IT COST?
Industry suggestions published by Forbes claimed the 100MW battery farm would cost between $A200 million and $A240 million.
Speaking to reporters on Saturday, Premier Jay Weatherill dismissed this price range and despite
refusing to reveal the exact cost to taxpayers, he said the project would fall well within the $150 million set aside for renewable energy alternatives.
Tesla’s battery division head Lyndon Rive originally suggested a price of $US400-600 kWh, which would put the cost of the 100MWh system at around $A66 million

Things always go over, so say $200 million 100MegaWatt or 100,000kilowatt hours.
100,000 kilowatt hours sells at $0.27 per KW hr or $27,000 worth of electricity per charge.
The battery is not designed to be charged and discharged every day, but only discharged when there is no wind.

Assuming then discharged every second day-- $200 million capital/$27000 of electricity
Payback = 7,407 days for electricity cost to equal battery cost. (not break even!!)
Discharged every second day 7,407 x 2= 14,814 days /365= 40.58 years

So 40 .58 years just to recover the cost of the battery, and that is with the incoming electricity is free!!!!

Except the battery will only last 10 years, = BIG GREEN FAIL
