The Qinghai-Hainan Clean Energy Delivery Base has officially commenced construction. The project, with a total planned investment of RMB 73 billion, spans both Qinghai and Hainan prefectures and will deploy 19.44 GW of generation capacity, comprising 9.60 GW of solar PV, 6 GW of wind power, 2.64 GW of supporting coal-fired capacity, and 1.2 GW / 4-hour electrochemical energy storage.
It is recognized as the largest renewable-energy installation and the project with the highest share of green power among all approved national ‘desert, Gobi and wasteland’ mega renewable bases to date. Once operational, it is expected to produce an average of 36 billion kWh of electricity annually, which will be transmitted directly to Guangdong via an ultra-high-voltage (UHV) DC transmission corridor.
Earlier this month, construction began on Phase III of the 2 GW Fishery-PV Complementary Power Project in Shandong Province, another ‘largest of its kind project’ in China (see China Solar PV News Snippets).
Integrated PV manufacturer JA Solar plans to launch a perovskite tandem cell R&D program through its subsidiary. According to the project filing published by the local government, the initiative will involve a total investment of RMB 423.75 million and will be carried out in JA Solar’s cell facility in Yiwu, Zhejiang Province.
The research will focus on perovskite-on-silicon tandem cell solutions. New equipment, including laser grooving tools, plate PECVD, plate PVD systems, full encapsulation equipment, and supporting automation systems, will be procured to establish a dedicated R&D center for high-efficiency perovskite-silicon tandem technologies. Construction is scheduled to begin this month and conclude in March 2026.
Recently, JA Solar published its research on perovskite tandem solar cell technologies, reporting its progress in the top-tier journal Energy & Environmental Science (see China Solar PV News Snippets).
The ‘Zhonglu Island Modern Marine Ranch Complex,’ developed by Jingneng International, a subsidiary of state-owned energy developer Beijing Energy International Holding, has received approval from the Development and Reform Commission of Yuhuan City. Designed as a national-level demonstration island for the marine economy, the project integrates green aquaculture, clean energy, and eco-tourism.
Located on Zhonglu Island in Yuhuan, Zhejiang Province, the project will utilize an already-certified sea area and plans to add more than 1,000 mu of demonstrative aquaculture zones. It will be equipped with 400 MW of marine renewable energy capacity, including 200 MW offshore wind and 200 MW offshore solar PV. Upon completion, the project is expected to generate approximately 940 million kWh of clean electricity annually.
The Hubei Provincial Energy Administration and Development and Reform Commission have released the province’s Energy Storage System Development Plan (2025-2030). The plan calls for a coordinated deployment of pumped-storage hydropower as the backbone and new-type energy storage as a supplementary resource, to build a storage system aligned with the province’s future power system architecture.
According to the plan, the province sets the following development goals:
By 2027: Total energy storage capacity must reach 8 GW, with 5 GW from new-type energy storage and 2.87 GW from pumped-storage hydropower.
By 2030: Total storage capacity must reach 17 GW, supporting the effective integration of more than 80 GW of renewable energy. This includes 8 GW of new-type energy storage and 9.12 GW of pumped-storage hydropower.
