CHN Energy has fully commissioned its 4 GW Lingwu PV project in Ningxia, following the grid connection of its Phase II 2 GW section. Part of a massive 6 GW mining-subsidence base, the site will deliver 10.8 TWh annually to the east via the 800 kV Ningxia-Zhejiang UHVDC line.

The project pioneers a 'solar-coal-storage-hydrogen' model, bundling PV with existing thermal assets and a 400 MW/800 MWh grid-forming storage system to smooth variability. By repurposing degraded coal lands, integrating 'PV + ecology' for vegetation recovery, and sharing an existing 750 kV coal plant substation, the base sets a benchmark for land reuse and long-distance clean energy transmission in western China.

[SMM PV Flash] Environmental Assessment Publicity for Gokin Solar PV Module Technological Transformation

On October 8, the Guangzhou Municipal Ecology and Environment Bureau approved the environmental impact report form for the high-efficiency PV module renovation project of Gokin Solar (Guangzhou) Technology Co., Ltd.'s 101# module workshop. According to the document, the project is located at No. 2, Hejin Avenue, Automotive Industry Base, Huadu District, Guangzhou. It does not add new land, with a current total site area of 266,532.22 m² and a building area of 213,018.29 m². The facility is primarily engaged in PV module production. This project involves the renovation of the 101# module workshop, and after the renovation, the annual production capacity will be 27.826 million high-efficiency PV modules (12.5217 million N-type TOPCon single-glass 72P, 1.3913 million N-type BC single-glass 72P, 8.3478 million N-type TOPCon dual-glass 72P, and 5.5652 million N-type BC dual-glass 72P). The total project investment is 120 million yuan, of which 1.6 million yuan is allocated for environmental protection.

[SMM PV Flash] PV-grade EVA Rally Continues

This week, a leading petrochemical producer raised the settlement price of PV-grade EVA from the previous cycle slightly to 11,300 yuan/mt. Cost side, raw material price fluctuations have narrowed recently but remain at a relatively high level, providing support for EVA costs. Meanwhile, some petrochemical units have successively entered maintenance, further tightening EVA supply. Foaming-grade EVA is also affected by tight supply, with prices continuing to rise, lending some support to the overall market. Overall, PV-grade EVA prices are expected to consolidate on a strong note in the short term.
