This is a list of energy storage power plants worldwide, other than pumped hydro storage. Many individual energy storage plants augment electrical grids by capturing excess electrical energy during periods of low demand and storing it in other forms until needed on an electrical grid. The energy is later converted back. . • • • • . • • • • The Moss Landing Energy Storage Facility, the world’s largest lithium-ion battery energy storage system, has been expanded to 750 MW/3,000 MWh.

Most of the world's grid energy storage by capacity is in the form of pumped-storage hydroelectricity, which is covered in List of pumped-storage hydroelectric power stations. This article list plants using all other forms of energy storage.
At any point in time since the early 20th century, the largest power station in the world has been a hydroelectric power plant. 1. 2. 3. 4.
The $207.8 million energy storage power station has a capacity of 300 MW/1,800 MWh and uses an underground salt cave. Chinese developer ZCGN has completed the construction of a 300 MW compressed air energy storage (CAES) facility in Feicheng, China's Shandong province. The company said the storage plant is the world's largest CAES system to date.

The $207.8 million facility boasts an energy storage capacity of 300 MW/1,800 MWh and occupies an area of approximately 100,000 m2. According to ZCGN, it is capable of providing uninterrupted power discharge for up to six hours, ensuring power supplies to between 200,000 and 300,000 local homes during peak consumption periods.
Battery storage power plants and uninterruptible power supplies (UPS) are comparable in technology and function. However, battery storage power plants are larger. For safety and security, the actual batteries are housed in their own structures, like warehouses or containers.

Tuvalu's power has come from electricity generation facilities that use imported diesel brought in by ships. The Tuvalu Electricity Corporation (TEC) on the main island of operates the large power station (2000 kW). Funafuti's power station comprises three 750 kVA diesel generators with 11 kV operating voltage, which was installed in 2007. Total power output is 1,800 kW. The old generators have remaine. [pdf]
Tuvalu's power has come from electricity generation facilities that use imported diesel brought in by ships. The Tuvalu Electricity Corporation (TEC) on the main island of Funafuti operates the large power station (2000 kW).
The Government of Tuvalu worked with the e8 group to develop the Tuvalu Solar Power Project, which is a 40 kW grid-connected solar system that is intended to provide about 5% of Funafuti ’s peak demand, and 3% of the Tuvalu Electricity Corporation's annual household consumption.
The pacific island nation of Tuvalu is on track to achieving its goal of 100% renewables by 2030, with the recent commissioning of a 500 kW rooftop solar project and 2 MWh battery energy storage system in it’s capital Funafuti. Image: United Nations Development Programme Pacific Office
The construction of pumped storage power stations among cascade reservoirs is a feasible way to expand the flexible resources of the multi-energy complementary clean energy base. However, this way makes the hydraulic and electrical connections of the upper and lower reservoirs more complicated, which brings more uncertainty to the power generation.
By 2020, the Pacific island state of Tuvalu aims to become the first country in the world to generate 100 percent of its electricity from renewable sources such as solar, wind, and biofuel. At present, some 77 percent of the country’s installed capacity comes from a power station on the island of Funafuti.
The first large scale system in Tuvalu was a 40 kW solar panel installation on the roof of Tuvalu Sports Ground. This grid-connected 40 kW solar system was established in 2008 by the E8 and Japan Government through Kansai Electric Company (Japan) and contributes 1% of electricity production on Funafuti.
