Technical FAQs 4

Why is new energy storage important in China?

SINGAPORE (ICIS)–New energy storage plays a crucial role in ensuring power balance in China, especially in effectively addressing the intermittent issues of new energy generation. It helps alleviate the dual pressures of power supply security and consumption.

How many electrochemical storage stations are there in China?

In terms of developments in China, 19 members of the National Power Safety Production Committee operated a total of 472 electrochemical storage stations as of the end of 2022, with a total stored energy of 14.1GWh, a year-on-year increase of 127%.

How can pumped-storage power (PSP) stations contribute to a low-carbon economy?

Facilitate the development of PSP station systems and a low-carbon economy. Optimizing peak-shaving and valley-filling (PS-VF) operation of a pumped-storage power (PSP) station has far-reaching influences on the synergies of hydropower output, power benefit, and carbon dioxide (CO 2) emission reduction.

How many electrochemical storage stations are there in 2022?

In 2022, 194 electrochemical storage stations were put into operation, with a total stored energy of 7.9GWh. These accounted for 60.2% of the total energy stored by stations in operation, a year-on-year increase of 176% (Figure 4).
