Forecast of Power Capacity Addition till 2040

Renewable energy will remain the fastest developing power sources in China in the future.

To expand the development of renewable energy has to overcome the problems and

challenges brought by its randomness and intermittently to the power grid.

Energy storage technology is used in renewable energy generation, which can convert

the random power generation into relatively stable output. It can improve the controllability of

power generation output, suppress power fluctuation, and improve the quality of power, so

that the wind power generation and PV generation can be widely used in power supply

system.

Generally speaking, China's energy storage development focus on the development of

pumped storage and electrochemical storage, such as Flow Batteries and Li-ion Batteries.

By the end of 2016, the installed capacity of energy storage units in China has reached

27GW, of which 99% is pumped hydro energy storage and 1% is electrochemical energy

storage.
