Battery
Electric energy is stored and utilized for adjusting the supply and demand of power generation. In Hokkaido, storage batteries have been installed in various locations. Notably, in Toyotomi Town, one of the world’s largest storage batteries has been installed for output adjustment of wind power generation.
The introduction of grid-scale storage batteries is rapidly increasing, approaching half of the annual average demand in the Hokkaido area.
- Grid-scale storage batteries are expected to become widespread as they can be utilized for power regulation to expand the adoption of renewable energy.
- To maximize the use of renewable energy in Hokkaido, storage batteries are an essential technology for stabilizing the power supply. They are also a critical component in forming microgrids and contribute to enhancing regional resilience.
Installation Status of Storage Batteries (Grid-Scale Storage Batteries and Regional Microgrid Storage Batteries)
- As equipment for adjusting wind power generation output, one of the world’s largest grid-scale storage batteries (720,000 kWh) has been installed in Toyotomi Town.
