Positioning of energy storage in the energy industry

What are energy storage systems?

Energy storage systems are technologies that store excess energy for later use, ensuring a reliable and stable supply of electricity when demand peaks. These systems are especially important for incorporating intermittent renewable energy sources, such as solar and wind, into the energy grid.

Why is energy storage important?

Energy storage is rapidly emerging as a vital component of the global energy landscape, driven by the increasing integration of renewable energy sources and the need for grid stability. As the world transitions towards cleaner energy systems, innovative storage solutions are gaining prominence, enabling more efficient use of renewable resources.

What is the external value of energy storage in China?

For China’s most widely used dual-pricing system, the external value of energy storage in the market can be regarded as reflecting and radiating value through the electricity market and capacity market, where the capacity market includes some functions of the ancillary services market.

How does energy storage work?

Energy storage creates a buffer in the power system that can absorb any excess energy in periods when renewables produce more than is required. This stored energy is then sent back to the grid when supply is limited.

What is a battery energy storage system?

Electricity storage systems play a central role in this process. Battery energy storage systems (BESS) offer sustainable and cost-effective solutions to compensate for the disadvantages of renewable energies. These systems stabilize the power grid by storing energy when demand is low and releasing it during peak times.

Will energy storage play a role in China's future power system?

As the Chinese government proposes ambitious plans to promote low-carbon transition, energy storage will play a pivotal role in China’s future power system.
