In fact, these tall, wide, white boxes are three banks of Tesla’s new industrial batteries. You’d only know if someone told you (or if you went around the back and found a small sticker with Tesla’s logo and some technical information). But unlike the ones in the renderings unveiled in late April by Elon Musk, the CEO of both Tesla Motors and SpaceX (and the chairman of Solar City, the largest provider of solar power in the United States), these are the real thing, part of a pilot project to see how the batteries—freed from the confines of the Tesla automobile—can help businesses with heavy energy needs.Like, say, a winery.Winery operators can’t afford to take constant power generation for granted. Lighting, air-handling systems, and refrigeration are all critical to the winemaking process. So last year, when a large earthquake and a small plane crash within a month of each other knocked out power at wineries he manages, Mitch Davis knew something had to be done.Davis works for Jackson Family Wines, which has 40 wineries around the world, including its most well-known brand, Kendall-Jackson. In 2012, Jackson Family Wines (JFW) initiated an ambitious green-energy effort with a single rooftop solar-thermal co-generation system. The company now has 6.5 megawatts of solar panels installed across eight wineries, all of which will be operational by the end of summer. That’s the equivalent of the electricity it would take to power 1,300 homes, and is, claims Julien Gervreau, JFW’s senior sustainability manager, the largest solar commitment in the winemaking industry.To read more online, click here.
