Late in May, the Shandong Energy Regulatory Office released the settlement of the new energy "two rules" and auxiliary services market in April 2021, and six energy storage power stations received a total of RMB267,500 in compensation for peak shaving. This is also the first time for Shandong Energy Storage Power Station to participate in the ancillary service market and publicize the compensation results.
Among the six energy storage power stations, Yuwangzhongjing Energy Storage Power Station has the highest peak shaving income of RMB92,383, ranking first in the province. The Tushanshengyang Energy Storage Project in Yantai, which was partly constructed by Yangguang Power, was the next, with RMB60,772. According to the data, the six photovoltaic power stations equipped with energy storage paid a total of RMB635,500 for peak shaving in April, while the energy storage income reached RMB267,500, accounting for 43.6% of the total allocation. The proportion of several energy storage power stations in the peak shaving allocation of the corresponding photovoltaic project varies from 12% to 61%.
At present, Shandong is vigorously promoting the development of energy storage. Shortly before the Shandong province issued The Implementation Opinions to Carry out the Energy Storage Application Demonstration, and the file points out that the new centralized wind power, photovoltaic power generation project, in principle should construct or lease storage facilities no less than 10%, and continuous charging time should be no less than 2 hours. The file has also clarified that compensation standard for energy storage demonstration project to participate in power grid peak shaving is RMB 200 / MWh. In addition, 1.6 hours of peak shaving priority power generation plan will be given for every 1 hour of charging accumulatively. The first energy storage demonstration projects will have a scale of about 500,000 kilowatts, and the policy is tentatively scheduled to be implemented for five years.
