How much energy storage capacity does the energy storage industry have?

New operational electrochemical energy storage capacity totaled 519.6 MW/855.0 MWh (note: final data to be released in the CNESA 2020 Energy Storage Industry White Paper). In 2019, overall growth in the development of electrical energy storage projects slowed, as the industry entered a period of rational adjustment.

How big are energy storage projects?

By the end of 2019, energy storage projects with a cumulative size of more than 200MW had been put into operation in applications such as peak shaving and frequency regulation, renewable energy integration, generation-side thermal storage combined frequency regulation, and overseas energy storage markets.

Which energy storage technologies are most important?

Physical energy storage technologies need further improvements in scale, efficiency, and popularization, and substantial progress is expected in 100 MW advanced compressed air energy storage, high density composite heat storage, and 400 kW high speed flywheel energy storage key technologies.

Should energy storage be included in the cost of transmission and distribution?

Such are the basic conditions for energy storage to be included in the cost of transmission and distribution of electricity. Energy storage is of vital importance to the energy transition. The opening of the power market can help elevate energy storage to become a natural core part of the power market.
