california aims to 'bottle sunlight' in energy storage push - home battery system

San francisco/Los Angeles-California's green ambitions help the solar and wind industries take root and are taking important next steps to propose a significant increase in energy storage to better integrate renewable energy with the rest of the grid.
Power fluctuations from the sun and wind are large, so capturing it for later use makes supply more predictable.
"We can't just rely on the sun," Governor Jerry Brown said at a solar conference in San Francisco last month . ".
"We have to bottle the sun.
"As renewable energy moves in the direction of empowerment, storage drives in California --
By 2020, the country's electricity supply was third.
The proposal triggered a technical competition that has attracted venture capitalists Peter Thiel and Vinod Khosla.

Not just California.
Germany was a pioneer in storage, and in the United States, the stimulus fund supported projects in New York and Texas.
But Golden State's ambitious renewable energy target is forcing the problem to come here: it wants to store up to 1.
It reached 3 gigawatts by 2020.
This capability is enough for traditional factories to provide electricity to more than millions of households.
Lux Research analyst Steven Minnihan says the California proposal is the first legislation to have a direct and lasting impact on the grid storage market, which he estimates will soar to $10 worth of installations
From $4 billion last year to $0. 2 billion in 2017.
But compared to building a new gas plant, storage costs are high, and many storage projects are built with the help of the economic stimulus fund, which means that utility customers will eventually get most of the labels.
There is also a risk that unverified storage technologies will not be able to fulfill their commitments.
"Taxpayers will be in trouble," said Farzad Ghazzagh, who is analyzing proposals from a branch of the California Utilities Commission, the taxpayer advocate department.
His analysis has not yet been completed, but it is estimated that it will cost $1 billion to $3 billion to install so many storage devices.
Supporters believe taxpayers will benefit because storage allows utilities to avoid building power plants or transmission lines to meet peak demand by providing only a few hours of additional electricity per day.
The electric power Institute found in a report this summer by the California grid regulator that the cost of storage is worth it if all the benefits are taken into account.
As with solar manufacturing, the storage business has encountered some difficulties in its efforts to reduce costs and prove technology.
Battery manufacturer A123 Systems and flywheel manufacturer Beacon Power LLC are one of the most eye-catching companies, both of which filed for bankruptcy after receiving generous support from the USS.
Department of Energy (DoE).
Both have reshaped themselves under new ownership.
The United States acquired A123 for $0. 257 billion. S.

Rockland Capital, a key private equity firm, bought it for $30.

Scott Harlan, managing partner at Rockland, said the third project did not require government support.
In addition to the battery, gates, Thiel and Khosla have all invested in compressed air starter light sail Energy this year, which has received a $1 reward.
7 million people from the California Energy Council demonstrated their technology at the Ventura County naval base.
Gates and Khosla have also invested in Ambri, another storage startup.
"Grid-scale storage has always been one of the areas where we know and know what will happen.
This is a matter of time, "said Andrew Chung, partner of Khosla Ventures.
The California push "really opens the door to startups," Chung added, and so far it has been difficult for these startups to extend small pilot projects to large purchases.
Lux's Minnihan said the real impact of the California initiative will be felt between 2020 and 2030, a move he expects will inspire efforts in other states.
The "Holy Grail" Storage is seen as the "holy grail" of energy because it brings efficiency to any grid.
For example, California has a peak capacity of 51 gigawatts to handle heat that increases air
Adjust the demand, even if there are only two-
It takes thirty most of the year.
Still, without more government funding, utilities like PG & E, Southern California Edison, and Sempra Energy in San Diego will bear most of the upfront costs. A natural gas-
The construction cost of thermal power plants is about $1,000 per kilowatt, while the break-even capital cost of the basic case of EPRI's battery replacement is $1,684 per kilowatt.
"As we sit here today, we all agree that storage is not economical," SunPower Corp Chief Executive Tom Werner said at a public utilities executive meeting in San Francisco.
"But if you go out for five years, I will not object.
"The potential of the market means that many people are willing to take the risk.
Elon Musk, an entrepreneur who founded Tesla Motors, is deploying the automaker's battery technology in solar systems installed by another company he supports, SolarCity.
"I am getting more and more confident that there will be a major breakthrough in ECG storage technology," Musk told Reuters's Global Market Forum chat room . ".
Germany subsidized a large sum of money.
In addition to rooftop solar, the company is actively funding storage devices to balance the grid and is expected to reach $19 billion in domestic market value by 2017.
Germany's gerdmeister company provides vanadium energy storage batteries for American miners and sells them in the U. S. market.
Batteries can charge electric vehicles, store wind and solar energy for the grid, and you can set up a micro-grid when the main power supply is not available.

At the same time, however, GE said that the new nickel chloride sodium battery system integrated into its own Tehachapi turbine is cheaper than the grid
Because it requires less investment in some hardware, it is a battery at the wind farm scale.
This technology keeps the power of the turbine stable in 15 to 30 minutes, thanks to the battery in the General Motors Volt electric vehicle.
This year, the project developer inpower will install three wind farms in Texas.
Venture capitalists have invested $2.
According to the clean technology group, storage capacity has reached 2 billion in the past five years, more than double the previous five years.
