Integrated solar manufacturer Tongwei has announced that its module manufacturing bases in Sichuan, Yancheng, and Nantong have received product water footprint verification statements from TÜV Rheinland for its TWMNH-66HD PV modules.
The company stated that the verification was conducted in accordance with ISO 14046:2014 and followed a ‘cradle-to-grave’ assessment framework, covering direct water use during production and indirect water consumption across the supply chain, in order to quantify water use and environmental impact over the product’s full life cycle.
Tongwei emphasized that it is the first PV manufacturer in China to complete a full life-cycle product water footprint verification.
Recently, Tongwei’s Advanced Photovoltaic Device Pilot Test Platform was one of 21 platforms selected by MIIT as a national-level manufacturing pilot test platform (see China Solar PV News Snippets).
Solar module and energy storage system manufacturer Risen Energy has signed annual strategic cooperation agreements for energy storage projects with 2 channel partners – Tingshan Energy and Haihe New Energy.
Tingshan Energy focuses on Guangdong, Zhejiang, and Shandong as its core markets. Under the agreement, the 2 parties plan to jointly deploy 50 MWh of energy storage systems (ESS) during the cooperation period, covering utility-scale, commercial and industrial (C&I), and residential storage projects.
Haihe New Energy, which specializes in EPC services with operations primarily in Shandong and Zhejiang, has also reached a cooperation scale of 50 MWh of energy storage equipment with Risen Energy.
Recently, Risen Energy announced that its Hyper-ion module series has achieved a carbon footprint of 301.765 kg CO₂-eq/kWc under the French carbon footprint assessment (see China Solar PV News Snippets).
The Hainan Provincial Development and Reform Commission, together with other authorities, has issued a policy notice on promoting the construction of zero-carbon industrial parks in the Hainan Free Trade Port.
The document proposes advancing low-carbon and zero-carbon transformation of various industrial parks in a planned and phased manner, and supporting qualified parks to take the lead in developing zero-carbon industrial parks. It also calls for stronger integration between industrial parks and surrounding zero-carbon energy sources, including wind, solar PV, solar thermal, biomass, and nuclear power, as well as the development of green electricity direct supply to parks.
Under the defined indicator system for zero-carbon industrial park construction, the policy explicitly requires that PV coverage on usable building rooftops must be at least 50%.
Jilin Province has released the results of its first round of mechanism-based electricity price bidding for renewable energy projects. The original plan targeted projects reaching full capacity operation between June 1, 2025, and December 31, 2026, with a total mechanism-based electricity volume of 4.58 billion kWh, including 3.86 billion kWh from wind power and 0.71 billion kWh from solar PV.
According to the results, 1,164 renewable energy projects were selected for a total allocated volume of about 4.05 billion kWh. Of the total, 1,141 solar PV projects secured approximately 0.28 billion kWh at a mechanism-based price of RMB 0.334 per kWh, while 23 wind power projects obtained about 3.78 billion kWh at RMB 0.250 per kWh.
Henan Province has released its mechanism-based electricity price bidding plan for wind and solar projects scheduled to come online between June 1, 2025, and December 31, 2026. The plan provides a total mechanism-based electricity volume of 10.51 billion kWh, including 3.91 billion kWh for wind power and 6.60 billion kWh for solar PV.
Both solar and wind projects are subject to the same bidding price ceiling of RMB 0.349 per kWh. However, the bidding floor differs by technology, with wind power set at RMB 0.113 per kWh and solar PV at RMB 0.121 per kWh. The awarded mechanism-based electricity prices will apply for a duration of 12 years.
