Energy market mechanisms must evolve in order to support long-duration energy storage, with the existing frameworks having "significant problems" incentivising those technologies, a panel of experts has concluded.
What are China's energy storage incentive policies?
China's energy storage incentive policies are imperfect, and there are problems such as insufficient local policy implementation and lack of long-term mechanisms . Since the frequency and magnitude of future policy adjustments are not specified, it is impossible for energy storage technology investors to make appropriate investment decisions.
Do policy adjustments affect energy storage technology investments?
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.
Do deterministic and uncertain policies affect energy storage technology investment?
To compare deterministic and uncertain policies' incentive effect on energy storage technology investment, this study selects the average peak and off-peak power price difference for energy storage participation in peak regulation auxiliary services in some Chinese provinces as a reference standard in this study.
What are the factors affecting energy storage technology investment?
In addition, there are also many uncertain factors in technological innovation and market related to energy storage technology investment. On the one hand, Technological innovations appear at random points in time and investors are unable to make decisions between adopting existing and new technologies.
Subsidy policies for energy storage technologies are adjusted according to changes in market competition, technological progress, and other factors; thus, energy storage subsidy policies are uncertain. In this section, the investment decision of energy storage technology with different investment strategies under an uncertain policy is studied.
Does China's policy uncertainty affect energy storage technology investment?
Meanwhile, China's policy uncertainty in energy storage technology investment presents as a valuable case study for other countries. Furthermore, the findings of this study are particularly helpful for energy storage investors and policymakers, not only in China but also in other countries.
