Tesla Planning Battery for Emerging Home Energy-Storage Market
By Dana Hull and Mark Chediak – Feb 11, 2015, 10:48:18 PM
(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.
But the even larger market may be utility clients.
“A lot of utilities are working in this space and we are talking to almost all of them,” Chief Technology Officer JB Straubel said on the earnings call Wednesday. “This is a business that is gaining an increasing amount of our attention.”
California sees energy storage as a critical tool to better manage the electric grid, integrate a growing amount of solar and wind power, and reduce greenhouse gas emissions. Utilities like PG&E Corp. are now required to procure about 1.3 gigawatts of energy storage by 2020, enough to supply roughly 1 million homes.

Hedge against Electricity BlackOuts from storms like Hurricane Sandy or Hot Summers.
By CHRISTOPHER MIMS
Elon Musk and his cousin, Lyndon Rive, have always been close. Their mothers are twins, and Messrs. Musk and Rive grew up together.
“We’ve known each other for as long as we’ve been conscious,” said Mr. Musk, speaking at a panel this week at a private conference in New York.
There is an obvious, almost brotherly affection between the two men. Mr. Musk says Mr. Rive “is an awesome guy and really hardworking and driven, and you can trust him with anything.” And when Mr. Rive recounts the drive to Burning Man in 2004 when Mr. Musk told him his next venture should be in solar power, Mr. Rive says that when Mr. Musk tells you what area to get into next, you get into it.
Their closeness continues, and if Messrs. Musk and Rive can achieve their shared vision, the result will be a transformation of the world’s, or at least America’s, energy infrastructure.
The companies the two men run—Tesla Motors Inc. and solar energy system provider SolarCity Corp.—are uniquely compatible. It isn’t just a product of the affiliation of their founders, but is also a consequence of Mr. Musk sitting on the board of SolarCity and being its largest individual shareholder.
Tesla makes cars, but it also—in the not too distant future—will make batteries. Lots of them. Tesla is building a $5 billion “gigafactory” in Nevada for batteries, one so large that it will, says Mr. Musk, be larger than the whole of earth’s current capacity for manufacturing lithium-ion batteries, most of which currently go into phones, tablets, laptops and other mobile devices.
At the conference Wednesday, Mr. Musk disclosed that a portion of the gigafactory’s capacity will be set aside for building “grid-scale storage.”
In other words, Tesla is going to continue its tradition of manufacturing battery packs for SolarCity, only on a much grander scale.
Up to now, SolarCity has sold Tesla-built battery packs to a handful of corporate and residential customers. The rationale is simple: The sun doesn’t always shine, so the best way to manage solar power on-site is to save it up for cloudy days and overnight.
SolarCity’s revenue has been growing 100% a year since its founding in 2006, and Mr. Rive says his goal is to maintain that pace for as long as possible. To that end, SolarCity announced in June the acquisition of Silevo, a Silicon Valley-based maker of solar panels that Mr. Rive insists is capable of producing at scale the most efficient solar panels on the market.
Mr. Musk said that while his gigafactory won’t exclusively sell grid-storage batteries to SolarCity, conversations with the company are “our best feedback as to deciding what the product would look like.”
Mr. Musk went even further, describing “the product” as a bank of batteries that “looks good,” is about 4-inches thick and can be mounted on the wall of the garage in a home.
Thanks to the economies of scale that will come from Tesla’s gigafactory, within 10 years every solar system that SolarCity sells will come with a battery-storage system, says Mr. Rive, and it will still produce energy cheaper than what is available from the local utility company.
Mr. Musk also noted that in any future in which a country switches fully to electric cars, its electricity consumption will roughly double. That could either mean more utilities, and more transmission lines, or a rollout of solar—exactly the sort that SolarCity hopes for.
America’s solar energy generating capacity has grown at around 40% a year, says Mr. Rive. “So if you just do the math, at 40% growth in 10 years time that’s 170 gigawatts a year,” says Mr. Rive. That’s equivalent to the electricity consumption of about 5 million homes, which is still “not that much,” he says, when compared with overall demand for electricity. “It’s almost an infinite market in our lifetimes.”
There are almost innumerable barriers to the realization of Messrs. Musk and Rive’s plan. For Tesla, there is the possibility that a superior battery technology could come to market soon after Tesla and its partner, Panasonic Corp., build their gigafactory, rendering their $5 billion investment obsolete. And SolarCity has almost the exact same problem with its ambition to build its own solar panels. While Mr. Rive says that Silevo’s technology is “next generation” and can compete with the cheap panels that China has been exporting to the rest of the world, the oughts are littered with the carcasses of U.S. solar panel manufacturers who claimed they could do the same, including Solyndra Inc.
And while this is a threat to shareholders rather than his aims, there is also the risk that Mr. Musk will find other, more efficient routes to reaching his stated goals, which include moving the world onto electric transport and solar power generation as quickly as possible.
For example, when asked whether or not the U.S. should erect trade barriers designed to protect American solar-panel manufacturers, Mr. Musk said: “If the Chinese government wants to subsidize the rollout of solar power in America, OK, it is kind of like ‘thank you’ is what we should be saying.” And in a subsequent interview at The Wall Street Journal’s offices in New York, Mr. Musk emphasized that “the reason I created Tesla was to accelerate the transition to sustainable transport. And I made that clear to investors.”
Despite the dumping of solar panels by China representing a substantial threat to SolarCity’s $750 million bet on Silevo—which includes a $350 million acquisition cost and an estimated $400 million to build a solar panel manufacturing plant in Buffalo, N.Y.—Mr. Rive agrees with Mr. Musk that there should be no barriers to trade in solar panels.
“Any extra tax on solar is just bad,” says Mr. Rive. “We have a big problem to solve—let’s solve that problem.”
That “big problem” is climate change. And Mr. Rive has been no less public than Mr. Musk about the purpose of his company being more than turning a profit. It’s one more thing their companies—and the two men—have in common.

Companies Unplug From the Electric Grid, Delivering a Jolt to Utilities
By REBECCA SMITH and CASSANDRA SWEET CONNECT

At Kroger’s food-distribution center in Compton, Calif., a tank system converts organic waste into biogas to produce electricity used by the facility
On a hill overlooking the Susquehanna River, two big wind turbines crank out electricity for Kroger Co.’s Turkey Hill Dairy in rural Lancaster County, Pa., allowing it to save 25% on its power bill for the past two years.
Across the country, at a big food-distribution center Kroger also owns in Compton, Calif., a tank system installed this year uses bacteria to convert 150 tons a day of damaged produce, bread and other organic waste into a biogas that is burned on site to produce 20% of the electricity the facility uses.
These two projects, plus the electric output of solar panels at four Kroger grocery stores, and some energy-conservation efforts are saving the Cincinnati-based grocery chain $160 million a year on electricity, said Denis George, its energy manager. That is a lot of money that isn’t going into the pockets of utilities.
From big-box retailers to high-tech manufacturers, more companies across the country are producing their own power. Since 2006, the number of electricity-generation units at commercial and industrial sites has more than quadrupled to roughly 40,000 from about 10,000, according to federal statistics.
Experts say the trend is gaining momentum, spurred by falling prices for solar panels and natural gas, as well as a fear that power outages caused by major storms will become more common.

“The battle cry is Hurricane Sandy,” said Rick Fioravanti, vice president of energy-storage technology at DNV Kema, a Netherlands-based consulting company.
The growing number of companies that are at least partly energy self-sufficient is sending a shudder through the utility industry, threatening its revenues and growth prospects, according to a report earlier this year by the Edison Electric Institute, a trade association for investor-owned electric companies.
State and federal regulators say they are worried that utilities could end up with fewer customers to pay for costly transmission lines and power plants.
Utility executives, meanwhile, are asking themselves a disquieting question: “Am I going to just sit here and take it and ultimately be a caretaker of a museum, or am I going to be part of that business” that’s emerging, said Nick Akins, chief executive of American Electric Power Co., a big Ohio-based utility. AEP is considering helping its customers install their own generating facilities.

How Fuel Cells Work
On-site generation still accounts for less than 5% of U.S. electricity production. But it is peeling off some of the bulk sales that utilities find especially profitable. And some of the companies getting into the business think it is approaching a tipping point called “grid parity,” at which point power would be as cheap to make as to buy from a utility.
Since 2007, when the first solar arrays went up on its store roofs in California, the installed costs of Wal-Mart Stores Inc.’s solar systems have dropped from $6 or $8 per watt of capacity to about $3.50 per watt, said David Ozment, the company’s senior director of energy management. He said he expects the retailer to be paying as little for solar power as utility power “in less than three years,” opening the floodgates to solar expansion.
Wal-Mart produces about 4% of the electricity it uses but intends to make 20% by 2020, taking advantage of idle acreage on thousands of store rooftops.
On-site generation isn’t a new idea. It existed before the electric grid—the interconnected system of power plants, substations and transmission lines that ferry power thousands of miles—was stitched together beginning in the 1920s.
But for most of the past 50 years, the practice was associated mostly with remote locations like Alaska fish canneries or industrial facilities like oil refineries that generated lots of waste heat that could be harnessed for power production.
Almost overnight, that niche market has gone decidedly mainstream. Six years ago, Google Inc. attracted attention by installing big solar arrays atop its Silicon Valley complex in California. Other tech companies followed suit, worried about ensuring power supplies for energy-hungry server farms and achieving sustainability objectives.
Apple Inc. now gets 16% of its electricity from solar panels and fuel cells that run on biogas. Apple’s data center in Maiden, N.C., makes all the power it consumes, a company spokeswoman said.
BMW AG’s assembly plant in South Carolina, which made 300,000 vehicles last year, gets half its electricity from an on-site energy center that burns methane piped to it from a nearby garbage dump. Drugstore chain Walgreen Co., which has solar panels at 155 stores, plans to install them at 200 more.
Falling equipment prices make on-site generation increasingly attractive. From 2002 to 2012, the cost of installed solar systems fell by half, according to an August report from the Lawrence Berkeley National Lab. Companies also have the option of leasing big solar systems, rather than incurring the capital cost of buying them.
Many “clean energy” projects also qualify for federal and state subsidies. In the case of solar installations, there is a 30% federal tax credit, which is set to drop to 10% in 2017. Government officials say a shift to greener energy resources is good since it reduces the output from coal-fueled power plants, which produce about 40% of the nation’s electricity and are the most polluting.
But analysts say the importance of subsidies has been waning, overshadowed by steep declines in the cost of power-generating equipment. For example, the cost of solar modules—the biggest single component in a rooftop solar system—has dropped about 80% in the past four years, to about 65 cents a watt from about $4 a watt, said Galen Barbose, a senior researcher at the lab.
Companies also are turning to wind turbines and technologies like fuel cells, batteries, small natural-gas turbines and reciprocating engines, which are natural-gas-fueled cousins of the auto’s internal combustion engine.
Engineering and technology company SAIC Inc. is installing enough generating capacity at a data center outside New York to meet the center’s core needs, with batteries for backup power. The system uses reciprocating engines burning natural gas, an option considered reliable in storms because gas pipelines are buried.
A report released by the White House in August estimated that power outages caused by bad weather cost the U.S. economy $18 billion to $52 billion a year in lost productivity from 2003 to 2012.
Demand for fuel cells in the U.S. is coming primarily from telecom companies, hotels and universities, said David Wright, CEO of ClearEdge Power Inc., a manufacturer in Hillsboro, Ore. Many buyers want reliable on-site generation as a hedge against storm-related outages.
By next year, Verizon Communications Inc. plans to install $100 million worth of fuel cells from ClearEdge and Bloom Energy, as well as solar panels, at 19 data centers and other facilities in seven states, including New York and New Jersey.
Some traditional utility companies are edging into the on-site generation business.
Edison International, which owns big utility Southern California Edison, recently bought a Chicago-based developer of rooftop solar projects, SoCore Energy LLC, and it is an investor in solar-finance company Clean Power Finance.
As power production becomes more decentralized, “I want to make sure the company is deeply involved,” said Edison CEO Ted Craver.
