During the Reporting Period, the Group’s approved capacity of photovoltaic projects increased by 320.08 MW, and the accumulative approved capacity of projects not yet commenced was 607.2 MW. The agreed capacity of photovoltaic projects increased by 7,260 MW and the accumulated agreed capacity of photovoltaic projects was 19,459 MW. As at the end of 2022, the Group operated photovoltaic power generation projects with accumulated capacity of 120.32 MW and accumulated installed capacity under management of 296.12 MW. The number of hours available for photovoltaic projects was 1,404, 9 hours up from the same period of last year and 67 hours higher than the national average of photovoltaic power used.

The Company participated in an equity investment for the construction of Hebei Fengning pumped storage power station project (河北豐寧抽水蓄能電站項目), the designed total installed capacity of which amounted to 3,600 MW, which will be developed in two phases with installed capacity of 1,800 MW each for pumping and water retention functions such as peak load regulation and valley filling. As of December 31, 2022, a total of 7 units had been put into operation under the Hebei Fengning pumped storage power station project （河北豐寧抽水蓄能電站項目）. During the Reporting Period, the agreed capacity of pumped storage of the Group increased by 6,400 MW. Four projects in Hebei, including Huanghuatan Pumped Storage Power Station in Laiyuan, Baoding; Qiaojiahe Pumped Storage Power Station in Yixian, Baoding, Sandaogou Pumped Storage Power Station in Luanping, Chengde, and Yangjiaqiao Pumped Storage Power Station in Pingshan, Shijiazhuang, with a total of 5,800 MW, have been included as key preliminary projects of pumped storage in Hebei Province during the “14th Five-Year Plan” period.

The Group actively attempted to explore investment in new energy storage projects. During the Reporting Period, the Weichang Flywheel Energy Storage Demonstration Project (圍場飛輪儲能示範項目) and the Jingjing Flywheel Energy Storage Demonstration Project (井陘飛輪儲能示範項目) developed by the Group, namely, were included in the “2022 List of Independent Energy Storage Demonstration Projects on the Grid Side of Provincial Planning (First Batch)” issued by the Development and Reform Commission of Hebei Province, which are located in the northern grid of Hebei Province and the southern grid of Hebei Province, respectively. The Group will also continue to try to invest in new energy storage projects outside the province.
