Tesla CEO Elon Musk expects 'hundreds' of battery gigafactories

Tesla Motors has officially announced it will build a massive electric vehicle battery factory, which it calls a gigafactory, to make a huge amount of cheaper lithium-ion pack for the EVs of the future. It says these packs are so important that it is working on plans for a gigafactory in two locations, just to make sure there is a Plan B if something goes wrong with Site A. But how many gigafactories could there one day be? According to Musk's vision, expressed at the World Energy Innovation Forum held at the Tesla Factory in Fremont this week (where he also said that using the Lotus Elise as the basis for the Tesla Roadster was not the best idea), the auto industry will one day need hundreds of battery gigafactories. Now, that's not hundreds of Tesla gigafactories, but he thinks there will need to be 200 just to supply the automotive industry. Throw in stationary energy storage and iPads that run all year, and the number climbs even higher. One benefit of all these cells coming to market will be cheaper electric vehicles. Originally, Tesla said that its gigafactory would be able to reduce the per-kWh cost of a Tesla battery pack by "more than 30 percent." Musk repeated that number at the Forum this week, saying, "I think we can probably do better than 30 percent." The groundbreaking of the first Tesla plant could take place next month. Oh, and as a side note: doesn't Michigan look odd in the image above? We are one with the lake, apparently.

Tesla making plans for Gigafactory in at least two states

Ever since February, when Tesla officially announced that it would build a gigafactory to make the incredible number of lithium-ion batteries it expects to need to power its electric vehicles, we thought it would be located in one of four states. Those four states – Texas, Arizona, New Mexico and Nevada – have been lobbying the automaker ever since, hoping to hear that the new, $5-billion plant and its 6,500 jobs would set up shop within its borders. Turns out, two of them might get some good news soon. "We want to minimize the risk timing for the gigafactory to get up and running" – Elon Musk CEO Elon Musk said Tesla will announce locations in "at least two" states where it could build the gigafactory, according to Bloomberg. He said, "What we're going to do is move forward with more than one state, at least two, all the way to breaking ground, just in case there's last-minute issues. The number one thing is we want to minimize the risk timing for the gigafactory to get up and running." This isn't to say that Tesla will actually build two gigafactories (at least, not yet, but Musk hinted there may come a day when the automaker will need a second one), just that it is going to make sure there is no hiccup in the supply of lower-cost battery packs for the upcoming lower-cost Tesla EV, sometimes referred to as the Model E. The gigafactory is expected to not only produce more li-ion cells than were made globally in 2013 but also to reduce the cost of the overall pack by 30 percent, setting the stage for the $35,000 Tesla EV (estimated) to appear.

Sun and wind could power Tesla Gigafactory for EV batteries in Nevada

Next week is Tesla Gigafactory week. The California automaker has a major announcement planned, and it's all about its intention to build a battery factory so large, the company is pulling out the giga prefix. At some point in the next seven days, we expect to hear where Tesla will build the plant, who it will partner with, how it will pay for it and lots of other details. The production volume is expected to be at least 30 gigawatt-hours-worth per year. The Gigafactory will take in the raw materials for lithium batteries and put out finished packs, not only for the electric vehicles made by Tesla and its automotive customers, but also for massive amounts of renewable energy storage – that's a niche the company plans to begin to occupy sometime early next year with residential-sized products. The production volume is expected to be at least 30 gigawatt-hours-worth per year. That's more storage than all the lithium battery factories in the world combined produce now. Color us impressed. Now, you might be thinking, "Is it really necessary to go that big at this point in time?" In a word: yes. Tesla CEO Elon Musk has said its upcoming, more-affordable vehicle – widely expected to be called the Model E – will wear a $35,000 price tag and boast a battery big enough to take it 200 miles on a charge. To achieve this, the cost of the cells needs to come down dramatically, and so it's no coincidence that the time frame for the new facility will parallel that of this car. According to Musk, the benefits from the economies of scale will see a cost drop between 30 and 40 percent. Of course, historically high prices are one of the main reasons why battery storage has not been widely used in the renewable energy sector, so this development could help drive more demand for cleaner, affordable energy, which, in turn, will drive demand for more storage. That's the kind of vicious cycle we like to see. Musk said the Gigafactory will be "heavily powered" by wind and solar energy. Speaking of renewables, that is where the Gigafactory will get much of its needed energy. During the call with financial analysts that accompanied the release of its 2013 fourth quarter earnings report, Musk mentioned that the new plant will be "heavily powered" by wind and solar energy, and will also use older Tesla packs for storage. These will help deflect the traditional arguments against wind and solar, that the sun doesn't shine at night and the wind doesn't always blow.
