Technical FAQs 4

What is a 4 hour solar energy storage system?

The system is designed to provide an optimal platform for 4 hours long-duration energy storage applications. As California increasingly relies on solar energy, the state often generates surplus solar energy during the day, this surplus presents an opportunity to shift power supply to meet the evening peak demand.

Why is energy storage important?

In the global energy transition, energy storage is key to integrating generation, grid, load, and storage systems. It enhances grid stability, addresses renewable energy intermittency, and supports a resilient, efficient, and sustainable energy infrastructure, enabling the seamless adoption of clean energy.

Will 4-hour systems bridge the supply gap?

While 4-hour systems bridge the supply gap with their ability to provide short-duration services and use their MWhs for longer periods, they will be of even higher relevance in the future, in which wholesale dominance is expected universally among forecast providers.

What is China's Energy Storage Center?

Through strategic partnerships with the Chinese Academy of Sciences, Zhejiang University, and the University of Electronic Science and Technology of Chengdu, the center advances the development and application of cutting-edge energy storage technologies. The company operates advanced energy storage factories with a total capacity of 4GWh.
