greening the grid: utility-scale energy storage - commercial energy storage systems

When power companies or companies announce that they need new power capacity to meet the growing demand for electricity, most people will think of new power plants and transmission lines.
But some companies have come up with something new: energy storage systems in the grid.
AES Energy Storage is such a company that is creating this emissions-and water-Free technology. Utility-
Scale energy storage technology--
There is no doubt that this will be the subject of clean technology that will be discussed in 2012 (
Quick start has started)--
By enhancing the role of renewable energy in meeting the demand side, especially during the peak period of the day, it can help the green grid.
It also helps to reduce the cost of electricity for consumers.
Brian Perusse, director of energy storage business development at AES, recently took the time to introduce us to more information on this innovative technology.
Here are some excerpts from the conversation.

What is energy storage, and what is it different from energy generation?
Energy storage is an emission.
Fast, highly flexible, readily available and ready for free capacity resources to power the grid.
It is different from other energy generators because it uses the grid as a "fuel" and can deliver or extract power from the grid as needed and at the most valuable time.
The unique ability to provide power and storage power makes the grid more efficient and reliable.
Describe the energy storage technology of AES.
How are they compared to other energy storage technologies?
Storage for AES Energy Storage-as-a-
It saves the need for pilot testing, system integration and technology selection risks.
It is impossible today to simply buy the battery and plug it into the grid, just like replacing the cell phone battery.
AES will perform all the work required to allow, design, engineer, purchase, build and operate an energy storage facility to meet the specific needs of utilities.
More importantly, AES has developed a control platform to optimize the performance of the energy storage system for each specific customer.
How does AES enter the energy storage business?
AES Corporation, the parent company of AES Energy Storage, is one of the world's largest power producers with 30-
A year of history as an innovator in the power industry.
This starts with the use of circulating boiling bed boilers and through advanced combined cycle gas turbine technology, new wind turbines and the latest thin-
Thin film solar technology such as Tellur cadmium.
Established in 2007, AES Energy Storage focuses on the commercial development and operation of the power grid
Scale energy storage.
AES Energy Storage believes that energy storage preparation plays a key role in clean energy
Provide energy equations for emissions
Free, flexible power resources, improve the grid today to prepare for the growing generation of renewable energy in the future.
Does AES have an energy storage project/system in operation?
We currently have 72 megawatts (MW)
In commercial activities or buildings, there are more and more pipelines in the 500 MW project.
Semester development.
We currently operate commercial energy storage facilities in West Virginia, New York and northern Chile.
In developing our business, we work with leading power system operators including ISO in New York, PJM interconnect, ERCOT in Texas, ISO in California and SING in Chile.
We are pleased to recently announce our participation in the commercial operation of the 32 mw storage project of PJM interconnect, the world's largest regional transport organization.
How does the traditional US electricity market model adapt to energy storage?
Energy storage can adapt to any number of market models, and we have deployed commercial facilities to pay for power services, as with other generators that provide the same service today.
Looking into the future, we expect to sign larger facilities contracts under the power procurement agreement, just as we see the development and procurement of wind, solar and traditional power plants.
Are energy storage competing or complementary to initiatives in renewable energy and efficiency? How so? Emissions-
Free capacity is a complement to renewable resources that can help decision makers, utilities and ISOs achieve clean energy goals.
By providing power to the system through emissions when needed most-
Advanced energy storage projects help to keep clean energy by integrating into the grid.
What is the impact of electricity storage on electricity prices?
Energy storage is actually storing energy from the cheapest and most efficient resources and providing energy when traditionally using more expensive resources.
In addition to providing lower energy than peak --
Natural gas plants, energy storage can provide many other benefits to the system, such as delaying transmission investment and reducing the risk of relying on any onefuel commodity.
