South Australia Continues Down “Stupid Is As Stupid Does” Path

South Australia is still tilting at windmills, the new version being solar energy. This “stupid is as stupid does” play yields ever higher electric prices.

South Australia, a state of 1.7 million people, is on a renewable energy kick and has encountered price and reliability issues. South Australia first invested in wind power and found wind’s reliability to be a problem when it shuttered its last coal plant that backed up the wind power and exposed its ratepayers to outrageous prices and massive black-outs. It then hired Tesla to install the largest storage battery in the world last November—a 100-megawatt lithium-ion battery—to provide back-up for wind’s intermittency, at a price of $50 million.

Now, South Australia will experiment with solar rooftop panels and Tesla Powerwall 2 batteries to form the world’s largest virtual power plant, costing $800 million. The project will cover 50,000 houses to be fitted with 5 kilowatt rooftop solar systems and 13.5 kilowatt hour Tesla batteries that together could provide up to 250 megawatts of solar power and 650 megawatt hours of storage.
