Chengdu is encouraging the integration of new energy storage systems with distributed photovoltaic (PV) installations to enhance the power grid’s capacity. On April 27, the Chengdu Municipal Government issued a notification outlining several policy measures aimed at strengthening the city’s electricity supply capabilities. One of the key highlights is the provision for land requirements for new energy storage projects.
For new energy storage stations that are included in the annual plan and occupy independent land, priority will be given to ensuring land use indicators according to public facility planning. In cases where public facility land is unavailable, industrial land may be utilized according to the regulations set for industrial parks. The land for user-side energy storage projects will be planned uniformly in conjunction with industrial parks and commercial enterprises.
For existing substations where construction is not feasible due to space constraints, the planning can allow for energy storage stations on the grid side. New public substations that meet construction conditions may be established nearby, ensuring a stable number of public substations. Furthermore, constructing new energy storage facilities on existing state-owned land will not require planning permits.
The policies also encourage the development of user-side energy storage. Following a principle of adaptability and flexibility, support will be provided for installing new energy storage systems at data centers, communication bases, commercial enterprises, industrial parks, and electric vehicle charging stations. Enterprises with high electricity consumption and stringent demands for power reliability and quality, such as those in precision manufacturing, finance, and battery production, are encouraged to install energy storage facilities as needed. Additionally, significant electricity users are urged to establish safe and reliable mobile or fixed energy storage systems as emergency backup power sources.
Moreover, the city aims to accelerate the construction of distributed photovoltaic projects. Specific areas have been designated for distributed PV development, categorized into red, yellow, and green zones to guide orderly growth based on demand. Projects in yellow zones should incorporate new energy storage systems with a capacity of no less than 20% of the installed capacity for 2-hour duration. In red zones, this figure should be at least 50%. The energy storage devices must be planned, constructed, and operated simultaneously with the photovoltaic projects.
Priority will also be given to ensuring electricity supply. During periods of demand response or other special circumstances, systems that include user-side storage and distributed PV, and that are connected to the virtual power plant with a capacity that exceeds 20% of the user’s average electricity load (calculated based on the average of the last seven days before the response, excluding the additional capacity from PV and storage), will be granted priority to meet their normal electricity needs, provided that the system operates safely and reliably.
This notification reflects Chengdu’s commitment to building a modern, first-class power grid and further enhancing the city’s electricity supply capabilities while promoting high-quality economic and social development.
