储能是电力系统不可或缺的灵活性调节资源。储能系统如何建设、使用，在一定程度上影响着电力结构调整进度。近年来，分布式光伏发展势头迅猛，装机量迅速攀升，推动分布式光伏和分散式储能相结合。同时，分布式光伏和储能相结合，在用户侧可以发挥保电、降低用能成本、降碳减排等功能，进而疏导储能成本，促进储能产业健康发展。

7月15日，昆山市人民政府办公室印发《关于加快推进分布式光伏发电项目开发建设的工作意见》。文件指出鼓励装机容量2兆瓦及以上的分布式光伏发电项目，按照不低于装机容量8%的比例配建储能系统 ， 储能系统作为分布式光伏发电项目组成部分一并办理备案。

截至目前，已有多地对分布式光伏配建储能设施提出了明确要求，分布式光伏配储建成趋势，新能源储能将逐步一体化！

江苏苏州： 2MW以上的分布式光伏，按不低于装机容量的8%配置储能，鼓励装机容量2兆瓦以上的光伏项目，按照不低于装机容量8%的比例配建储能系统。

5

山东枣庄： 分布式光伏项目按照装机容量的15%-30%、时长2-4小时配置储能设施，或者租赁同等容量的共享储能设施；

6

河北： 屋顶分布式光伏项目逐步按照“光伏+储能”方式开发建设，可选择自建、共建或租赁等方式灵活开展配套储能建设，配套储能装置应满足10年（5000次循环）以上工作寿命，系统容量10年衰减率不超过 20%。

可以预见的是，随着部分地区试点先行，成效显著后再进行推广，分布式光伏配建储能将有广阔的市场空间。

Energy storage is an indispensable flexible regulation resource in power system.  How to construct and use energy storage system affects the progress of power structure adjustment to a certain extent.  In recent years, the development momentum of distributed PV has been rapid, and the installation volume has risen rapidly, which promotes the combination of distributed PV and distributed energy storage.  At the same time, the combination of distributed photovoltaic and energy storage can play the functions of power preservation, energy cost reduction, carbon reduction and emission reduction on the user side, so as to channel the energy storage cost and promote the healthy development of the energy storage industry.

July 15, Kunshan City people's Government office issued "on accelerating the development and construction of distributed photovoltaic power generation project working opinions".   The document points out that distributed photovoltaic power generation projects with installed capacity of 2 MW or more are encouraged to build energy storage systems at a rate of no less than 8% of the installed capacity, and the energy storage systems shall be registered as part of distributed photovoltaic power generation projects.  

Up to now, many places have put forward clear requirements for distributed photovoltaic collocation and energy storage facilities. The trend of distributed photovoltaic collocation and storage is complete, and new energy energy storage will be gradually integrated!

Zhuji, Zhejiang: The capacity of photovoltaic energy storage facilities should not be less than 10% of the installed photovoltaic capacity while the distributed photovoltaic development is required. The new energy storage facilities constructed in Zhuji City can receive a one-time energy storage facility investment subsidy of 200 yuan /kWh from the municipal finance.   Enterprises investing in new energy storage facilities can rent and sell energy storage capacity to photovoltaic investment enterprises in a market-oriented way, and the leased and sold capacity can be regarded as 10% energy storage quota.

Zhejiang Yongkang: Encourage non-household distributed photovoltaic power stations to build energy storage facilities according to 10% of the installed power generation capacity, make full use of the time-of-use tariff mechanism, proactively cut peak and fill valley, and optimize the load demand of regional power grids.   In the scheme, it is proposed that energy storage projects on the side of non-residential users (annual utilization hours no less than 600 hours) should be subsidized according to the power of energy storage facilities, and the subsidy standard is 150 yuan, 120 yuan and 100 yuan/kW.

Shaoxing, Zhejiang: It is recommended that in the whole life cycle of non-household distributed photovoltaic power stations, energy storage facilities should be built according to 10% of the installed power generation capacity. The storage time of energy storage facilities should be more than 2 hours, so as to provide certain capacity support and regulation ability for the power system.

Suzhou, Jiangsu: For distributed PV over 2MW, energy storage shall be installed at least 8% of the installed capacity. Photovoltaic projects with installed capacity over 2MW shall be encouraged to install energy storage systems at least 8% of the installed capacity.

Zaozhuang, Shandong: Distributed photovoltaic projects are equipped with energy storage facilities according to 15%-30% of the installed capacity and lasting for 2-4 hours, or rent shared energy storage facilities with the same capacity;

Hebei: Rooftop distributed photovoltaic projects are gradually developed and constructed in accordance with the "photovoltaic + energy storage" mode. Supporting energy storage construction can be flexibly carried out by self-construction, co-construction or leasing. Supporting energy storage devices should meet the working life of more than 10 years (5000 cycles), and the 10-year decay rate of system capacity should not exceed 20%.  

 

 

It can be predicted that with the pilot in some areas first, and then promoted after remarkable results, distributed photovoltaic energy storage will have a broad market space.
