AES Energy Storage has developed and deployed grid-scale energy storage projects in five different US Regional Transmission Operator systems and in the Northern grid of Chile. Beginning with our initial systems in 2008, the company has a proven track record of combing leading technology suppliers with solid engineering, construction, and operations of energy storage systems for the power grid. The projects below highlight our capabilities to take energy storage from the concept stage, through development, and into operations.
AES Energy Storage Projects
Angamos - 40 MW - in Operation
Overview
The Angamos project provides critical contingency services to maintain the stability of the electric grid in Northern Chile, an important mining area. The project continuously monitors the condition of the power system and if a significant frequency deviation occurs, such as the loss of a generator or transmission line, the Angamos system provides up to 20MW of power or load nearly instantaneously This output can be maintained for 15 minutes at full power, allowing the system operator to resolve the event or bring other standby units online.
The fast, frequency responsive capabilities of this project help improve the restoration response time of the system and avoid unneccesary emergency load shedding.

Laurel Mountain - 64 MW - In Operation
Overview
The Laurel Mountain energy storage project is a fully-integrated portion of the Laurel Mountain Wind Farm, develop with AES Wind. The energy storage portion of the project provides frequency regulation in the PJM market while also being available to help manage the rapid rate of change of output that can occur with fluctuations in wind conditions. The project achieved commercial operation in the third quarter of 2011 and is currently supplying emissions free operating reserve capacity in the PJM market.

Los Andes - 24 MW - in Operation
Overview
The Los Andes project provides critical contingency services to maintain the stability of the electric grid in Northern Chile, an important mining area. The project continuously monitors the condition of the power system and if a significant frequency deviation occurs, such as the loss of a generator or transmission line, the Los Andes system provides up to 12MW of power or load nearly instantaneously This output can be maintained for 20 minutes at full power, allowing the system operator to resolve the event or bring other standby units online.
The fast, frequency responsive capabilities of this project help improve the restoration response time of the system and avoid unneccesary emergency load shedding.

Johnson City - 16 MW - in Operation
Overview
Johnson City is expected to be the largest Li-ion battery system in commercial service on the US power grid when completed. Phase 1 (16MW) is currently online and supplies frequency regulation to the New York Independent System Operator (NYISO) market. This new regulation capability will add to the responsiveness of the power system and help support thousands of MWs of wind development expected to occur in New York over the coming years.
The project is adjacent to an existing AES generating station.

Project Barbados - 2 MW - Commercial Pilot Completed
Overview
Project Barbados went online in November 2008 as the first Li-ion battery system connected to the power grid for commercial services. This system completed the certification testing for regulation, similar to a generating unit, and has been in use since that time, with high demonstrated levels of availability. The Project is paid and settled as a regulating resource in the ancillary services market.
The Project has been recognized by PJM as an innovative approach that brings important fast reponse capabilities to the market.

Project Sano - 4 MW - Pilot System in Operation
Overview
Project Sano is a 4MW energy storage resource installed in 2008 adjacent to an existing AES Corporation generating plant. This unit passed the required system certification testing for frequency regulation and was involved with several pilot efforts with the California Independent System Operator (CAISO) as they evolve their market for new technologies.
The project is used primarily as a testing and controls development platform today and was a succesful part of a demonstration project by AES Energy Storage and it's technology partners.

Project Carina - 4 MW - Technical Pilot Completed
Overview
Project Carina was a first of its kind project, succesfully demonstrating the use and benefit of a multi-megawatt scale Lithium-ion battery based storage system for providing ancillary services on the power grid. Launched in 2007, the Project was completed in early 2008. KEMA Consulting performed the system validation demonstrating its capability to effectively perform a frequency regualtion profile, maintain a state of charge, and perform in ancillary services markets.
The Project was completed with the cooperation of AES Energy Storage, Indianapolis Power & Light, Parker-Hannifin, Altairnano Technologies, Sargent & Lundy, and KEMA Consulting.
