Battery Energy Storage System (BESS)

Research Target:

BESS companies

Research Content:

With the growing adoption of renewable energy, both grid-scale battery energy storage systems (BESS) and BESS installed at renewable power plants are drawing increased attention as key solutions for enhancing power-generation resilience.

Following the May 2022 revision of the Electricity Business Act, operators that discharge electricity from BESS with an output capacity of 10 MW or more are now classified as electricity utilities.

For the purposes of this report, “BESS businesses” refer to companies that generate revenue through the wholesale electricity market and the demand response market. This report examines current market trends and provides an outlook on the future development of BESS businesses.
