As of 2023, pumped-storage hydroelectricity (PSH) was the largest form of grid energy storage globally, with an installed capacity of 181 GW, surpassing the combined capacity of utility-scale and behind-the-meter battery storage, which totaled approximately 88 GW. [44]
Holtsville Energy Storage Project Battery, Li-Ion 440 110 4 United States Holtsville, New York 2025 Holtsville Energy Storage, LLC is a proposed 110 MW / four-hour battery energy storage facility in Brookhaven, New York, with enough storage energy capacity to power 18,366 homes, bringing numerous positive impacts to the local community and economy.
Hornsdale Power Reserve is a 150 MW (194 MWh) grid-connected energy storage system owned by Neoen co-located with the Hornsdale Wind Farm in the Mid North region of South Australia, also owned by Neoen. The original installation in 2017 was the largest lithium-ion battery in the world at 129 MWh and 100 MW. [1]
The company stated that Megapack was designed to meet the needs of large-scale battery storage projects, as with the Powerpacks. [3] Tesla acquired a former JC Penney's distribution center in Lathrop, California, in 2021 and converted it into a battery plant called Megafactory, [4] with a target capacity of 40 GWh/year when finished.

Dec. 7—AUSTIN — As part of continued efforts to increase transparency into grid operations, ERCOT on Thursday announced the new Energy Storage Resources (ESR) dashboard and Integration Report ...
Companies engaged in generating electricity from renewable energy with battery storages are poised for massive growth.
However, grid batteries do not have to be large, a large number of smaller ones (often as hybrid power) can be widely deployed across a grid for greater redundancy and large overall capacity. As of 2019, battery power storage is typically cheaper than open cycle gas turbine power for use up to two hours, and there was around 365 GWh of battery ...
In 2013, the database covered 409 projects; it aimed to cover all energy storage projects globally by 2014. [2] By 2020, it covered 1,686 projects, [3] comprising 22 gigawatt power of US grid storage capacity. Pumped-storage hydroelectricity is around 90% of the energy capacity. Storage facilities are 80% efficient. [4]
