Which country has the most battery-based energy storage projects in 2022?

In 2022, the United States was the leading country for battery-based energy storage projects, with approximately eight gigawatts of installed capacity.

What type of energy storage is available in the United States?

In 2017, the United States generated 4 billion megawatt-hours (MWh) of electricity, but only had 431 MWh of electricity storage available. Pumped-storage hydropower (PSH) is by far the most popular form of energy storage in the United States, where it accounts for 95 percent of utility-scale energy storage.

What is the total MW of battery storage in the US?

As of December 2017, there was approximately 708 MW of large-scale battery storage operational in the U.S. energy grid. Most of this storage is operated by organizations responsible for balancing the power grid, such as Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs).

How many GW of pumped-storage hydropower are there?

According to the U.S. Department of Energy (DOE), the United States had 22 GW of PSH storage incorporated into the grid in 2015. This amount has increased by 2 gigawatts (GW) in the past 10 years.

Who operates most of the large-scale battery storage in the US?

Most of the 708 MW of large-scale battery storage operational in the U.S. energy grid is operated by organizations charged with balancing the power grid, such as Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs).
