Excerpt: ADELAIDE, Australia — The state of South Australia announced on Friday that it had powered up the world’s biggest battery ahead of schedule: a feat already being heralded as one of this century’s first great engineering marvels and a potential solution to the country’s energy woes. The battery is the size of an American football field ...capable of powering 30,000 homes, and its rapid deployment reflects the union of a blackout-prone state and a flashy entrepreneur, Elon Musk, the founder of Tesla Motors, who pledged to complete its construction in 100 days or do it for free. ...Debate over the battery’s potential has become intense. Federal lawmakers who favor fossil fuels argue that its impact is being exaggerated, while supporters gush that the state’s embrace of Mr. Musk could change the future of energy in Australia — and the world. ...South Australia has the highest electricity prices in the world. This imbalance of supply and demand has resulted in regular blackouts and astronomical bills for the state’s 1.7 million residents. The high-capacity Tesla battery does not create energy, it just stores it. The state already invests in wind and solar energy. The battery would give it a bank of saved energy, which could ease pressure during periods of high demand and help better manage the electrical grid. “More than 40 percent of South Australia’s electricity is coming from wind, which is good,” said Tony Wood, an energy director at the Grattan Institute, a think tank. “But the consideration of how to integrate it — and manage that intermittency — wasn’t so good.”...  https://www.nytimes.com/2017/11/30/world/australia/elon-musk-south-australia-battery.html
