During the Reporting Period, the Group added 42 MW of registered photovoltaic capacity, and the total capacity of projects registered but yet to be commissioned amounted 649.2 MW. It added 1,000 MW of new agreed photovoltaic capacity and the cumulative effective agreed photovoltaic capacity was 10,958 MW. As at the end of 2023, the Group operated photovoltaic power generation projects with an accumulative operating capacity of 126.12 MW and accumulative installed capacity under management of 296.12 MW. The utilization hours of photovoltaic projects were 1,376 hours, a decrease of 28 hours as compared with the previous year, which was 90 hours higher than the national utilization hours of solar power announced by the China Electricity Council.

The Group 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 load shifting and valley filling. As at 31 December 2023, the Hebei Fengning Pumped Storage Power Station Project had a total of 10 units in operation. In May 2023, the NDRC issued the Notice on Capacity Tariffs of Pumped Storage Power Stations and Related Matters, approving the capacity tariffs of 48 pumped storage power stations in operation and intended to be commissioned by the end of 2025, of which the capacity tariff of the Fengning Phase I Project was RMB547.07/kW and the capacity tariff of the Fengning Phase II Project was RMB510.94/kW.

During the Reporting Period, the Group added an independent storage agreement capacity of 500 MW for a 500 MW shared storage power station project in Antu County, Jilin Province. The Qingxian 2*480MW Gas Power Plant Project developed by the Group has obtained approval from the HDRC, and its Ruoqiang Suntien 160,000 kW/640,000 kWh independent new energy storage project has completed filing with and obtained approval from the Development and Reform Commission of Bayinguoleng Mongol Autonomous Prefecture in Xinjiang Autonomous Region. Meanwhile, the Group will also try to invest in new energy storage projects in Hebei and beyond.
