Average mobile ESS unit price per 20kWh in China

How much energy storage capacity will China have by 2030?

To meet the demand from its power system, China will have to cumulate 460 GWh of energy storage capacity by 2030, among which 350 GWh shall be battery or electrochemical energy storage, and 110 GW pumped hydro storage.

What is the price gap between ESS and batteries?

In March, the price disparity between ESS and batteries has continued to shrink. The average price of a 280Ah/0.5C storage battery hovered around 0.38 yuan/Wh in March 2024. According to our data, the average winning price for a 2-hour ESS is approximately 0.63 yuan/Wh, resulting in a price gap of around 0.25 yuan/Wh.

How much does a MWh system cost?

MWh (Megawatt-hour) is a measure of energy capacity (how long the system can continue delivering that power output). For example, a 1 MW / 4 MWh BESS has four hours of storage capacity.So, while the system might be $200,000 per MW, the effective cost can be $800,000 per MWh if it has four hours duration.

What is China's energy storage capacity?

China's electrochemical energy storage capacity grew rapidly, with 5 GWh added in 2021 (an 89% year-on-year increase) and 15.3 GWh added in 2022 (a 206% year-on-year increase).

What happened to ESS bid prices in March 2024?

In March 2024, ESS bid prices varied depending on their storage capacity, with an overall downward trajectory evident, particularly in the case of four-hour ESS bids, which hit yet another all-time low. Raw material prices for storage battery are expected to remain stable. At the outset of 2024, battery prices experienced a decline.

Why is energy storage a problem in China?

Issues such as poor actual operating rates of renewable-storage integrated facilities continue to strangle the development of energy storage in China. Currently, China is still managing to refrain from fossil fuel imports, aiming to reach carbon peak and carbon neutrality by 2060.
