Ranking of state grid energy storage project scale

What is the preferred choice for grid-scale storage?

Lithium iron phosphate batteries, a subset of lithium-ion batteries, are still the preferred choice for grid-scale storage based on cost and energy density considerations.

What is the market for grid-scale battery storage?

The current market for grid-scale battery storage is dominated by lithium-ion chemistries.

What is the grid-scale battery storage capacity in 2022?

In 2022, the installed grid-scale battery storage capacity is 11 GW. Grid-scale battery storage in particular needs to grow significantly. In the Net Zero Scenario, installed grid-scale battery storage capacity expands 35-fold between 2022 and 2030 to nearly 970 GW.

When will large-scale battery energy storage systems come online?

Most large-scale battery energy storage systems are expected to come online in the United States over the next three years. These systems will be built at power plants that also produce electricity from solar photovoltaics.

Can stationary energy storage improve grid reliability?

Although once considered the missing link for high levels of grid-tied renewable electricity, stationary energy storage is no longer seen as a barrier, but rather a real opportunity to identify the most cost-effective technologies for increasing grid reliability, resilience, and demand management.

What was the grid-scale battery technology mix in 2022?

In 2022, the mix of grid-scale battery technologies remained largely unchanged from 2021. Lithium-ion battery storage was the most widely used, making up the majority of all new capacity installed.
