Tesla represents only a fraction of the likely demand growth. According to BMI, China will build twice as much new lithium-ion battery capacity as the U.S. by 2020. Lithium is relatively abundant in the earth’s crust but often hard to get to, and the technology needed to extract it can differ from one deposit to another.

I can see this being a good buffer for solar or wind power. Even an hour of reserve can help with flow of electricity. The wind can stop or clouds can come over and it increases demand on the coal plants during that time. The battery can also absorb spikes so that it does not go back into the generators or panels, although it would be cheaper to install capacitors to help with a lightning strike. I use a whole house surge protector now, it works well, so did the battery backup I first got. But the battery backup only protected the computer, the surge protector protects the house. We got lots of surges before, I hate having things burn out and it is hard to prove that lightning killed things unless you have multiple things burn out at the same time. Insurance deductable is two hundred fifty bucks, the surge protector cost me seventy bucks.
Your lithium-ion batteries power your smartphone, laptop, and camera. Elon Musk’s powers South Australia. On December 1, a mega-battery built by Musk’s Tesla company was officially activated and is now supplying power to an electricity grid in South Australia. On Friday, RenewEconomy posted some of the results of Tesla’s efforts in Australia and they were rather impressive. Apparently, the battery has reduced service costs by as much as 90 percent.
“In the first four months of operations of the Hornsdale Power Reserve (the official name of the Tesla big battery, owned and operated by Neoen), the frequency ancillary services prices went down by 90 per cent, so that’s 9-0 per cent,” said McKinsey and Co. partner Godart van Gendt.
Did anyone ever mention the war torn Afghanistan..? That’s where the most lithium comes from (free of charge)…!

Only about 30% of US power generation comes from coal fired plants. It's mostly all natural gas plants now.
The stunning numbers behind success of Tesla big battery
The Tesla big battery in South Australia has already taken a 55 per cent share in the state’s frequency and ancillary services market, and lowered prices in that market by 90 per cent, new data has shown.
The stunning numbers on the economics of the country’s first utility-scale battery were presented at the Australian Energy Week conference in Melbourne on Thursday by McKinsey and Co partner Godart van Gendt.
Speaking as part of a panel on the leading technologies and strategies that will help manage the transition to renewables in Australia, van Gendt said the data was more evidence that battery storage would “play a very big role.”
He said that a lot of discussion around the success of the big battery – the biggest of its kind in the world, and delivered at break-neck speed – had focused on the fact that “we did it,” and not on the economics.
“So, I thought I’d give you a few numbers from the market data,” van Gendt said.
“In the first four months of operations of the Hornsdale Power Reserve (the official name of the Tesla big battery, owned and operated by Neoen), the frequency ancillary services prices went down by 90 per cent, so that’s 9-0 per cent.
“And the 100MW battery has achieved over 55 per cent of the FCAS revenues in South Australia. So it’s 2 per cent of the capacity in South Australia achieving 55 per cent of the revenues in South Australia.
“So that’s great for the first battery in the market,” he added, “but if you’ve already had 55 per cent of the FCAS that are now gone, right… and a 90 per cent drop in price, then the business case for the second battery, of course, is a bit less attractive.
1.1 Services provided by the Hornsdale Power Reserve
1.1.1 Energy arbitrage
Under normal conditions, 30 MW of the battery’s discharge capacity is made available to NEOEN for commercial operation in the National Electricity Market (NEM). Of the battery’s total 129 MWh energy storage capacity, 119 MWh may be used for this mode of operation.
1.1.2 Reserve energy capacity
The remaining 70 MW of battery discharge capacity is reserved for power system reliability purposes. This 70 MW reserve capacity has not been dispatched to date. (snip)
1.1.3 Network loading control ancillary services (NLCAS)
1.1.4 Frequency Control Ancillary Services (FCAS)
2.1.1 Quality of regulation FCAS delivery
Data available to AEMO demonstrates that the regulation FCAS provided by the HPR is both rapid and precise, compared to the service typically provided by a conventional synchronous generation unit. (snip)
Not to mention if you own a Prius or hybrid then I guess you're quite fine with child slavery. Cobalt anyone?
Not to mention that if you are driving an all-electric car you are essentially subsidizing the coal industry, if you live in America. Where do you think the electricity from your house comes from?
a sum of money granted by the state or a public body to help an industry or business keep the price of a commodity or service low.
On topic, if Musk is so bedazzling smart, why not tie the battery to solar? Wind and Tidal are stupid inefficient.
iirc, a prius does more damage to the earth than a one ton pickup in it's serviceable lifespan. no links handy, just something I remember seeing... batteries are a nasty business.
Yawn. Not only is this old “news” but it too late for his company. There are several technologies that blow his tech out of the water.
Flow batteries is the best one. Next is thermal energy storage. Then, energy generation will be more efficient. His whole battery factory will be passe when graphene batteries come out. It is a losing battle no matter what you feel about him. He is behind the curve.
HPR also provided regulation FCAS to South Australia during the activation of the 35 MW FCAS constraint on 14 January and 8 March 2018. Historically, during the times that this constraint has bound, regulation FCAS prices in South Australia have typically exceeded $9,000/MWh due to the limited number of suppliers of these services in the region. However, on 14th January, HPR provided additional supply into FCAS regulation markets (Figure 20), and average Raise and Lower Regulation prices were $248/MWh during the event. AEMO estimates that this reduced the cost of regulation services by about $3.5 million during the five hour period in which the constraint bound.
