More ‘Gigafactories’

Tesla’s utility-scale battery will consist of 100 kilowatt-hour blocks that can be grouped to a scale of 500 kilowatt-hours to more than 10 megawatt-hours.
Palo Alto, California-based Tesla is making a bet that its $5 billion “gigafactory” under construction near Reno, Nevada, will enable the mass production needed to drive down battery costs for both cars and energy-storage products that are already serving as a revenue stream for the company. More such factories will be needed to help make the transition from fossil fuels to renewable energy, Musk said.
Tesla, whose batteries are already supplying large customers like Wal-Mart Stores Inc., Cargill Inc., and Jackson Family Wines, has formed partnerships with companies including Green Mountain Power to sell its home batteries, it said. The company is also teaming up with Southern California Edison to install batteries for utilities, while Amazon.com Inc. and Target Corp. will pilot use of Tesla’s batteries for businesses.
