The World\'s Largest Lithium-Ion Battery Farm Comes Online

For nearly a month, a group of 53-
The walking container on the Laurel Mountain Ridge in West Virginia has been drawing power from wind turbines extending in two directions.
These containers have the largest lithium in the world.
Ion battery farms for storing and delivering energy to the grid, the project reflects the emergence of a technology that helps manage the growing production of renewable energy in the country.

The MW project responds quickly to the purchase request from utilities and uses short-lived electricity at different times of the day to balance supply and demand.
The project serves the wholesale market operated by pjm interconnection, which covers 13 states in the eastern United StatesS.
AES announced the start of the energy storage project on Thursday, although it has been serving the PJM grid since Sept. 30. The AES-

Ion batteries from A123 System are located at 98-
Megawatt wind farm built by AES wind power company.
AES Energy Storage and AES wind power are all part of Va Arlington. -based AES Corp.
The success of the Laurel Hill project may be convincing utility lithium-
Ion batteries are ideal for energy storage in power grids.
Although lithium
Ion batteries are common in consumer electronics such as laptops and iPhones, and they just start to appear in cars and companions in power plants.
\"The grid storage market is relatively small, but it is growing and technology costs are falling,\" said John zahurankk, vice president of energy storage operations and deployment at AES . \". Grid-
Connected Energy storage is not a new concept, but it is not popular either.
Pumping water-delivering water to the reservoir and then releasing it to run the generator-is an old and most common method of bank energy.
According to the Power Research Institute for utilities, as of 2010, the technology accounted for 99% of the world\'s 122,866 MW grid energy storage system. Lithium-
By the end of last year, the Ion battery project had a total of about 20 MW worldwide. Lithium-
Ion is not the only battery used for energy storage in the power grid.
Several other types, such as the type of thread usedacid, sodium-

The ion battery encapsulates more energy in a small space, which is smaller in weight and more efficient in operation (
Store and provide more power)
Than some type of battery. But lithium-
Ion battery systems also tend to be more expensive, though as more batteries are designed and manufactured for grid energy storage, their prices should drop, zahurankk said. Lithium-
Ion batteries are one of the most expensive energy storage technologies, says EPRI.
Pumping water and some other non
Battery technology that has been around for a while is much cheaper.
The emergence of grid energy storage technologies and devices corresponds to the increasing number of wind and solar energy that utilities use to meet the national task of using cleaner power sources.
Wind and solar power cannot be generated around the clock, and their power generation cannot be predicted.
The energy storage system helps smooth any process of quickly injecting power into the power grid, which can only work properly if supply and demand balance.
Other companies that are testing lithium using pilot projects-
Ion batteries include Edison in Southern California, Portland General Electric in Oregon and DTE Energy in Michigan.
There are several ways to make money from energy storage.
Storage operators can sell electricity in a short period of time to help utilities and grid operators maintain a balance of supply and demand in seconds or minutes, or they can provide longer periods of electricity during peak hours of energy use, like when people go home at night and turn on lights, TVs and various other appliances.
AES designed the Laurel Hill project for power regulation, in part because the demand for this service has always existed.
Utilities often need to reserve electricity every day to cope with any fluctuations in the grid, which allows AES to calculate the extent of demand and the prices that may be charged, zahurankk said. The 32-

Minute increments.
In the future, AES hopes to build more energy storage farms and supply power for several hours at a time.
This service can gradually replace the demand for fossil fuels.
Based on power plants.
To achieve this, the company will need to be able to build larger and larger projects at a lower cost and design control systems and software to run them.
\"We believe the market will eventually move towards lithium-
\"Ion batteries will bring great efficiency to power generation systems and significantly reduce emissions,\" zahurankk said . \".
Demonstrating its ability to build and operate larger storage systems will also help AES and other storage field developers who choose lithium
Ion batteries-financing projects lined up from banks.
Lenders generally do not fund projects that use new and unverified technologies, and if they do, they may charge a capital premium.
AES built the Laurel Hill project with its own money, and the company declined to disclose its cost.
The company has set up an 8-
Megawatt storage systems in New York and 12-
Megawatt project in Chile.
Is currently building a 20-
Megawatt storage in Chile.
