Energy storage (ESS)
−5.81%ESS
The energy storage system (ESS) theme covers companies that make batteries and related hardware for storing electricity, such as large battery packs for utilities, data centers, and homes, along with power conversion and control equipment. Korean investors often group these firms together because they share exposure to the same drivers, including the expansion of renewable power that needs storage to smooth output and demand for backup power. Many of these companies are also linked to the broader battery supply chain, so their shares tend to move with global electric vehicle and grid-storage trends.
