A deluge of batteries is about to rewire the power grid

A pale orange-and-gold sunset bathes the macadamia plantations and avocado orchards that sweep down to Australia’s Byron Bay. The coming dusk is a cue for two sleek Tesla battery packs in the garage at Amileka, a secluded holiday villa nearby. They stir silently into action—powering the appliances in the five-bedroom home’s twin kitchens, recharging a $100,000-plus Model X SUV, driving a filter pump for an 18-meter swimming pool sparkling in the shade of a century-old native black bean tree.
