Energy Storage Project Subsidy Policy Document
The notice outlines subsidy policies for new energy storage, including the following: Independent energy storage capacity will receive a capacity compensation of 0.2 CNY/kWh discharged,
View DetailsThe government's incentive funds, including policy publicity and fiscal subsidies designed to encourage investment and industrial growth among energy storage operators, are insufficient compared to the national fiscal subsidies granted to the energy storage industry. Specifically, the subsidy coefficient S 1 <a D.
Additionally, the energy storage capacity subsidy is a one-time payment of 200 CNY/kW, while there are ongoing subsidies for charging and discharging (0.5 CNY/kWh) and for peak-valley arbitrage (0.7 CNY/kWh). The energy storage system is assumed to operate for 300 days annually, with two charge-discharge cycles per day.
The subsidy period lasts for 3 years following the completion of the energy storage project. Furthermore, depreciation and maintenance costs for the energy storage system are estimated to be 4 % of the initial system investment cost. The relevant data are summarized and presented in Supplementary Information Table D.1.1.
Government subsidy levels both influence and are influenced by energy storage operators' engagement and power system transformation. Energy storage operators become proactive when their participation profit coefficient exceeds a critical threshold.
As of 2024, China has introduced policies and measures related to energy storage, which primarily fall into four typical categories, encompassing investment subsidies for energy storage projects [17, 18], subsidies for charging and discharging [19, 20], subsidies for installed capacity [21, 22], and subsidies for demand response [23, 24].
The energy storage industry in Chongqing, China, is governed by a comprehensive set of subsidy policies. As such, relevant data from this region more accurately reflect the impact of governmental subsidies on this sector.
