Europe, China and Japan also has focused on developing energy storage in recent year. Currently United States leads the world in terms of deployment of energy storage technologies for the grid applications. US currently has over 24 GW of energy storage deployed for grid applications. Here are the list of top 5 major energy storage projects going on across the world.

In November 2008, AES installed 1-MW –250 kWh Altairnano Li-Titanate system to the parking lot the PJM Interconnection's headquarters building. That unit has been wired into a feeder line and has been selling frequency regulation into the PJM Ancillary Service Market since January 2009. It has been in almost continuous operation since May of 2009.
AES Energy Storage and A123 Systems announced the commercial operation of a 12 MW – 4 MWh frequency regulation and spinning reserve project at AES Gener's Los Andes substation in the Atacama Desert, Chileo 18th Nov 2009. The project helps improve the reliability of the electric grid in Northern Chile and uses A123 Systems' Hybrid Ancillary Power Units, a lithium -ion battery system.
AES Laurel Mountain energy storage facility utilizes 32 MW Li-Ion batteries along with 98 MW wind farm to supply ancillary services to the grid. The project has been operational since October 2011.
Based on success of AES Los Andes project, in 2012 AESGener and AES Energy Storage announced the commercial operation of the second energy storage project in Northern Chile, integrating 20MW of advanced battery - based energy storage with a 544MW thermal power plant.
Beacon’s Stephen Town Frequency regulation plant utilizes 200 high speed flywheels to provide fast frequency regulation service to NYISO since 2011. The plant is rated at 20 MW – 5 MWh and was the largest energy storage facility providing frequency regulation US at the time of installation.
