HOW DOES IT WORK?

It starts with a single cell.

It is the same lithium-ion battery technology found in your tablet, laptop and cell phone

 

Over 44GWh of advanced battery production capability were online in 2012.

Grid battery systems from AES depend on prominent brand name suppliers that have been producing batteries for 20 years.

GRID BATTERIES

ARE RECHARGEABLE

Batteries on the grid are always plugged in, so they never run out.

Batteries help to maintain balance between supply and load.

On the power grid, batteries can act as both generation and load, serving multiple functions:

Battery Based grid storage is in commercial operation today.

A total of 1.5 million MWh of service delivered, AES has the most comprehensive and accomplished fleet of battery-based energy storage in the world.

IS IT DEPENDABLE?

There when you need it.

A 64 MW energy storage resource consists of 1.3 million batteries – each its own unit of power.

Compare this with a power plant, which typically has only 3 or 4 units, and the reliability implications become clear.

Grid battery resources are designed in array architectures to increase reliability and eliminate downtime.

If one of millions of batteries does not perform, the resource continues working.

Energy storage helps to keep the lights on.

IS IT SCALABLE?

A meaningful grid resource.

 Battery-based energy storage shares a supply chain with the transportation and consumer electronics industries.

This established supply chain ensures that they can become a meaningful grid resource.

Energy storage arrays are modular by nature, making it easy to add up to hundreds of MW capacity.

The cumulative manufacturing of grid-ready batteries can outpace established resources.

Worldwide pumped hydro installed base
In the next 10 years, the cumulative manufacturing of grid-ready batteries will be greater than the installed base of pumped hydro.
By 2024, the cumulative grid-ready battery capacity will exceed combustion plant capacity by more than 4X.

With no additional fuel, water use or emissions, they are easier to permit and can be deployed quickly to meet expanding needs over time.

IS IT SUSTAINABLE?

There when you need it.

Battery-based energy storage enables an expanded renewable energy future.

The EIA expects 28,000 MW of new renewables in the next 10 years.
At the same time, 82,000 MW of power plants will be retired.

Energy storage can serve as a replacement resource for aging power plants to absorb renewable energy. In fact, energy storage is doing this today.

The AES Laurel Mountain battery array is charged entirely from wind generation.

The AES US battery fleet is estimated to reduce associated emissions by 62,000 tons of CO2, 329 tons of SO2 and 97 tons of NOx per year.

Battery-based storage creates a resilient grid.

It is an always-on resource with no emissions or water use.

In PJM, the AES US battery fleet enables the system to absorb variable renewable energy giving the regional grid operator the ability to balance a full 104 MW of variation in less than 1 second.

Batteries are recyclable

Batteries last more than 15 years.

They are centrally located, making for easy recycling at the end of their useful life.

HOW MUCH DOES IT COST?

Over the next 25 years, the US EIS predicts we will invest over $75 billion on peaker plants.

A portion of that planned investment can be applied to energy storage, with greater benifit.

The bottom line:
Energy storage costs less than a peaker power plant.

The switch to storage has already begun.

AES' battery facilities in Ohio and West Virginia have already delivered $20 million of benefit to ratepayers vs. approaches using power plants.
