Tesla Wants to Build a Battery for Your House

12th of February 2015

(Bloomberg) — Tesla Motors Inc., best known for making the all-electric Model S sedan, is using its lithium-ion battery technology to position itself as a frontrunner in the emerging energy-storage market that supplements and may ultimately threaten the traditional electric grid.“We are going to unveil the Tesla home battery, the consumer battery that would be for use in people’s houses or businesses fairly soon,” Chief Executive Officer Elon Musk said during an earnings conference call with analysts Wednesday.Combining solar panels with large, efficient batteries could allow some homeowners to avoid buying electricity from utilities. Morgan Stanley said last year that Tesla’s energy-storage product could be “disruptive” in the U.S. and in Europe as customers seek to avoid utility fees by going “off-grid.” Musk said the product unveiling would occur within the next month or two. "We have the design done, and it should start going into production in about six months or so,” Musk said. “It’s really great.”Tesla already offers residential energy-storage units to select customers through SolarCity Corp., the solar-power company that lists Musk as its chairman and biggest shareholder. Tesla’s Fremont, California, factory is also making larger stationary storage systems for businesses and utility clients. The Palo Alto, California-based automaker has installed a storage unit at its Tejon Ranch Supercharger station off Interstate 5 in Southern California and has several other commercial installations in the field
