What is a battery energy storage system?
A battery energy storage system (BESS) is an electrochemical device that charges from the grid or a power plant and then discharges that energy to provide electricity or other grid services when needed.
Are utility-scale battery energy storage systems a source of electric power?
Utility-scale battery energy storage systems have been growing quickly as a source of electric power capacity in the United States in recent years. In the first seven months of 2024, operators added 5 gigawatts (GW) of capacity to the U.S. electric power grid, according to data in our July 2024 electric generator inventory.
How do energy storage systems work?
Instead, they store electricity that has already been created from an electricity generator or the electric power grid, which makes energy storage systems secondary sources of electricity. Energy storage systems use more electricity for charging than they provide when supplying electricity to the electricity grid.
How many MW is battery energy storage?
In 2010, only 4 megawatts (MW) of utility-scale battery energy storage was added in the United States. In July 2024, more than 20.7 GW of battery energy storage capacity was available in the United States. Battery energy storage systems provide electricity to the power grid and offer a range of services to support electric power grids.
What is battery storage and why is it important?
Battery storage is one of several technology options that can enhance power system flexibility and enable high levels of renewable energy integration.
Can batteries save energy?
Batteries are “a really obvious solution” to reducing need for peakers, says Daniel Chu, senior energy planner for the New York City Environmental Justice Alliance. Storing extra power in batteries also extends the hours of the day that you can use clean energy.
