According to data from the National Energy Administration, the new installed capacity of wind and light in 2020 will hit a record high of 120GW. As of the end of 2020, my country's wind power and photovoltaic grid-connected installed capacity reached 280 million kilowatts and 250 million kilowatts respectively. And under the macro background of the national “30·60” carbon emission reduction, the installed capacity of new energy is still full of imagination.

        However, as the penetration rate of photovoltaic and wind power in the entire power system continues to increase, how to adapt new energy to the grid has become a top priority. Among them, the importance of energy storage is self-evident.

        As a result, at the beginning of the "14th Five-Year Plan", Shanxi, Ningxia, Qinghai, Inner Mongolia, Guizhou and other provinces have released new energy configuration energy storage plans, and photovoltaic + energy storage will also become the mainstream mode of future photovoltaic power station development.

        However, it should be noted that the current economics of energy storage are still not perfect, and the rigid requirements for energy storage in photovoltaic power plants will inevitably bring additional costs to developers. According to calculations by industry insiders, at present, although the winning unit price of energy storage EPC has dropped by 23% from the beginning of 2020, based on the 20% installed capacity of the photovoltaic project and the energy storage time of 2 hours, the supporting energy storage will increase the initial investment cost of the enterprise by 8%- 10%.

The proportion of new energy projects with energy storage equipment is not less than 10%, and the energy storage time is more than 2 hours. And give priority support to integrated projects with a high energy storage ratio and a long time. Implement the "Hydropower + New Energy + Energy Storage" coordinated development model. New energy and energy storage systems are simultaneously configured for newly built and newly put into operation hydropower stations, so that the ratio of newly added hydropower to new energy and energy storage capacity reaches 1:2:0.2. Balance in place. In addition, the trial draft clarifies that the province’s power grid electricity sold by the self-generated and self-storage facilities in the "new energy + energy storage" and "hydropower + new energy + energy storage" projects will be given an operating subsidy of RMB 0.10 per kilowatt hour. The Ministry of Information Technology has identified projects that use more than 60% of the energy storage batteries produced in the province, and an additional subsidy of 0.05 yuan per kilowatt-hour will be added. The subsidy targets are electrochemical energy storage projects that will be put into production in 2021 and 2022. The subsidy time limit is tentatively set for January 2021. From 1st to December 31st, 2022.

4. Inner 

        Mongolia On January 25, the Energy Administration of Inner Mongolia Autonomous Region issued the "Inner Mongolia Autonomous Region Renewable Energy Power Consumption Guarantee Implementation Plan". The "Plan" calls for vigorously developing new energy and further increasing the capacity of renewable energy power consumption. The total amount of renewable energy power consumption will be more than 25%, and the high-quality development of renewable energy in the autonomous region will be promoted.
