From the article: "If electricity is delivered whenever it 'feels like' being delivered (when the wind is blowing somewhere or the sun is shining), it won't meet the demand-unless the consumer for that electricity has its own gigantic battery storage (which Griffith actually recommends that a household buy). But Griffith does tell us the real cost of solar energy-at least of rooftop solar. He says, 'Remember that the average US cost of grid-based electricity is 13.8c per kilowatt-hour. If rooftop solar achieves the price point it has in Australia of 6-7c per kilowatt-hour, and if batteries achieve a price point of around the same 6-7c per kilowatt-hour per storage cycle, then we will have arrived at that moment when our battery storage can beat the grid on cost.'" I realize it's (massive) utility-scale, but Bhadla[1] has seen energy price bids at 3.2c per kWh. Meanwhile, for residential electrical storage batteries, Spirit Energy quotes[2] an effective cost-per-cycle of around 13p (approximately 16c) in the UK.
