6 FAQs about [Guorong energy storage adjustment]

What is the investment threshold for energy storage in China?

At this stage, the investment threshold for energy storage to involvement in China's peaking auxiliary services is 0.1068 USD/kWh. In comparison, the current average peak and off-peak power price difference in China is approximately 0.0728–0.0873 USD/kWh.

How does policy uncertainty affect energy storage technology investment in China?

Policy adjustment frequency and subsidy adjustment magnitude are considered. Technological innovation level can offset adverse effects of policy uncertainty. Current investment in energy storage technology without high economics in China. Subsidies of at least 0.169 yuan/kWh to trigger energy storage technology investment.

How to judge the progress of energy storage industry in China?

Chen Haisheng, Chairman of the China Energy Storage Alliance: When judging the progress of an industry, we must take a rational view that considers the overall situation, development, and long-term perspective. In regard to the overall situation, the development of energy storage in China is still proceeding at a fast pace.

Should energy storage charge and discharge strategies be adjusted?

Shandong, Gansu and other regions implemented complete price adjustments for all TOU periods. While the widening of the peak and off-peak price difference is beneficial to behind-the-meter energy storage applications, energy storage charge and discharge strategies must also be adjusted to adapt to the changes to the peak and off-peak period.

Do policy adjustments affect energy storage technology investments?

The primary conclusions are summarized as follows: The frequency of policy adjustments and the magnitude of subsidy adjustments have different levels of impact on energy storage technology investments. The adverse effect of the subsidy adjustments magnitude is much more significant than the impact of the policy adjustments frequency.

Should energy storage be invested in China's peaking auxiliary services?

Therefore, direct investment in future energy storage technologies is the best choice when new technologies are already available. At this stage, the investment threshold for energy storage to involvement in China's peaking auxiliary services is 0.1068 USD/kWh.
