Construction has begun on Phase III of the 2 GW Fishery-PV Complementary Power Project in Zhanhua District, Binzhou City, Shandong Province. Jointly developed by State Power Investment Corporation (SPIC) and Weiqiao Pioneering Group, the project is being built with a total investment of RMB 10.2 billion. It includes 2 GW (AC) / 2.58 GW (DC) of solar power generation and a 200 MW / 400 MWh battery energy storage system (BESS). Installed on saline-alkali tidal flats, the PV modules are paired with aquaculture below, forming an ecological ‘fishery-solar complementary’ system which is said to be China’s largest of its kind currently. According to local media Shandong Radio and Television, Phases I and II, totaling around 1 GW, have already been grid-connected, while Phase III (350 MW) is now under construction.
Earlier this month, China’s first semi-submersible integrated offshore wind-solar-fishery platform, the CHN Energy Yellow Sea No.1 project, was completed (see China Solar PV News Snippets).
China’s oil and gas giant Sinopec is advancing an integrated wind-solar hydrogen production project in Ulanqab, Inner Mongolia, with an annual capacity of 100,000 tons.
The total investment in the project amounts to RMB 20.5 billion, with an annual green hydrogen output of 100,000 tons and a supporting 2.546 GW renewable power installation. Sinopec has recently completed project registration for the 800.8 MW PV section, which is scheduled to begin construction in June 2026 and is expected to be completed by December 2028, comprising 182 PV arrays.
The generated electricity from both PV and wind farms will supply the hydrogen production system, which will have a design hydrogen capacity of 100,000 tons per year and a hydrogen storage capacity of 261 tons when fully operational.
In July, a subsidiary of Sinopec officially commissioned a 7.5 MW floating PV (FPV) project to supply power to its hydrogen production facility (see China Solar PV News Snippets).
China’s National Energy Administration (NEA) has released a document titled ‘Guiding Opinions on Promoting Integrated Renewable Energy Development’, outlining plans to achieve large-scale, high-level integration of renewable energy by 2030.
The policy emphasizes coordinated development of diverse energy types, promoting complementary multi-energy systems. It calls for optimizing storage configurations at large-scale renewable bases in desert, Gobi, and wasteland areas – mainly solar PV – while leveraging concentrated solar power (CSP), pumped hydro, and new energy storage to support 100% renewable bases. For the distributed sector, the document encourages the development of transport-plus-PV projects, building-integrated photovoltaics (BIPV), and rural distributed wind and PV systems.
Hainan Province has announced a competitive auction process for the 2025-2026 period to determine the mechanism tariff for new energy projects.
The bidding covers wind and solar projects scheduled for full grid connection between June 1, 2025, and December 31, 2026, with a total mechanism power volume of 9.877 billion kWh – comprising 8.232 billion kWh from offshore wind and 1.645 billion kWh from onshore wind and PV combined. The bidding ratio for individual projects is capped at 85%. For onshore wind and PV, the price ceiling is set at RMB 0.3998/kWh, with a floor price of RMB 0.2/kWh, which will be valid for 12 years. For offshore wind, the ceiling is RMB 0.4298/kWh and the floor is RMB 0.35/kWh, with a 14-year term.
Qinghai Province has announced the results of its 2025 renewable power mechanism pricing auction, which attracted lower-than-expected subscriptions.
The bidding covered renewable projects commissioned between June 1 and December 31, 2025, totaling 2.241 billion kWh, of which 1.608 billion kWh are solar PV and 0.633 billion kWh wind. The price range for PV projects was RMB 0.18-0.24/kWh, and RMB 0.205-0.24/kWh for wind.
In total, 27 projects were shortlisted, all securing a tariff of RMB 0.24/kWh, effective for 12 years starting in 2026. Among them, 23 PV projects account for 1.12 billion kWh, and 4 wind projects account for 0.543 billion kWh.
