In 2020, domestic storage capacity will break 53GW

At the 6th China International Energy Storage Conference recently held, the China Energy Storage Applications Branch of the Chemical and Physical Power Industry Association released the "Research Report on China's Energy Storage Applications (2016)" (the "Report").

The "Report" pointed out that it is estimated that during the "13th Five-Year Plan" period, the domestic energy storage market will show a rapid development trend. By 2018, it will be an advanced application stage of energy storage technology demonstration; in 2020, the application of advanced energy storage technologies will be vigorously promoted on the user side; in 2030, the application of advanced energy storage technology solutions will be popularized.

From the market trend, it is estimated that by the end of 2020, the accumulated energy storage systems in 6 major areas such as domestic auxiliary power market, base station backup power, wind power generation, distributed generation and microgrid, new energy vehicle refueling substation and household energy storage are expected to accumulate Installed capacity of 53GW, the next five-year compound annual growth rate of 9.5%.

From the six major areas of supporting energy storage situation is expected by the end of 2020, the power auxiliary market, base station standby power, wind power generation, distributed generation and micro-grid, new energy vehicle charging station and household energy storage and other six major areas The cumulative installed capacity of supporting energy storage systems were 25GW, 21GW, 6.2GW, 364MW, 228MW and 42MW, respectively. The top three fields accounted for 98.8% of the market.

From the technical trend of supporting storage batteries, it is estimated that by the end of 2020, the accumulated installed capacity of physical storage in China will be 31GW, accounting for 58.8% of the total storage capacity. The storage capacity of chemical storage will still be about 22GW. The market Accounting for 41.2%.
