About Grid-Scale Energy Storage
In recent years, while the adoption of renewable energy has been progressing rapidly, solar power generation, in particular, faces the challenge of significant output fluctuations depending on weather and time of day. Therefore, "grid-scale energy storage," which can balance supply and demand by charging during surplus power periods and discharging during shortages, is expected to play a central role in power infrastructure.
