Renewable power can come in fits and stops, depending on whether the wind is blowing and if the sun is shining, but the supply doesn’t always come at the exact same time as demand. Improved batteries could help utility companies store power from renewable power to even-out the spikes and spikes and valleys those sources produce. And, of course, residential homes could store more solar power from their own solar panels to reduce their reliance on the over- taxed grid—a reduction that utilities would also welcome.
可再生能源是具有间歇性的，取决于是否在刮风，取决于太阳是否在发出光亮，但是在对可再生能源有需求的时候却不一定会有供给。经过改进后的电池可以帮助电力公共事业公司储存来自于可再生能源的能量和其他资源产生的能量。并且，可以肯定的是，居家户可以通过自家的太阳面板储存更多的太阳能，减少对电力的过度依赖，这种减少也受到公共事业公司欢迎。
Tesla’s move into the electrical utility market isn’t exactly novel says Sam Jaffe, a former industry analyst at Navigant Research and founder of battery technology company Cygnus Energy Storage. There are already dozens of companies offering battery packs for utility companies. But he says Tesla’s move is a validation of the market, and its scale will make it a major player.
Navigant Research前市场分析师、Cygnus Energy Storage电池科技公司创始人山姆.杰夫说道，特斯拉进驻电力公共市场的举动并不是特别新奇。现在已经有几十家公司为电力公共事业公司提供电池支撑。但是他也说道，特斯拉的举动是经过市场验证后的结果，其经营范围将使特斯拉成为市场的主要参与者。
“In 10 years the grid will be cleaner, less expensive to maintain, and more reliable,” Jaffe says. “And that will be thanks to energy storage technology.”
“电网在未来十年都将是较为清洁的能源，同时维护费用也比较低廉，且更可信。”杰夫说道，“这点要多亏能源储存技术。”
Excess Capacity
超额生产能力
Tesla’s first expected foray beyond cars also highlights that the company’s battery manufacturing capacity may soon be its strongest asset. Last year [Tesla announced](http://www.wired.com/2014/02/teslas-giant-battery-factory- save-apple/)its plans to build a 10-million-square-foot battery manufacturing plant istened the Gigafactory. That capacity could easily be put to use building batteries for not just cars and houses, but for electronics such as laptops and cell phones. And that could be just the beginning.
特斯拉第一次针对汽车市场的达到预期的突袭，也同时表明其公司的电池制造产能将在不久的以后占据公司最大的资产份额。去年，特斯拉宣布其将建立以Gigafactory命名的、占地千万平方米的制造工厂计划。如此生产能力将很快的投入到电池的使用中，这些电池不仅是为汽车和家庭提供电力，也为其他电子设备供电，比如掌上电脑和收集。这一点可能仅仅只是特斯拉举措的开始阶段。
