From late September to early October 2025, the Chinese photovoltaic market will experience a peak in bidding. Several state-owned enterprises and energy companies, including China National Energy Corporation, China Power Construction Corporation, Datang Corporation, and Zhong'an Electric Investment Corporation, have successively released bidding notices for EPC general contracting of photovoltaic projects, with a cumulative installed capacity of 1715MW (approximately 1.7GW). The project types cover various modes such as photovoltaic desertification control, agricultural photovoltaic complementarity, and full self use.

This round of bidding includes five key projects. The largest 600MW photovoltaic sand control project in Yecheng County, Xinjiang, is being tendered by Zhong'an Power Investment (Henan) Energy Co., Ltd. for the construction of a 60MW/120MWh energy storage system. It is planned to be fully connected to the grid by December 31, 2026. The project is divided into two bidding sections, requiring bidders to have at least two EPC projects of 100MW or above centralized photovoltaic power plants in the past five years.

The National Energy Group's 214MW photovoltaic project in Inner Mongolia adopts a fully self operated mode, with an actual installed capacity of 256.8MWp, and will be equipped with a new 110kV booster station and a 9-kilometer transmission line. The project has a planned duration of 12 months and requires bidders to have 2 photovoltaic EPC projects with a capacity of 100MWp or more. Joint venture bidding is not accepted.

The Xizang 50MW photovoltaic sand control pilot project of CEC is located in Shigatse City, with a total planned construction period of 6 months. It will achieve full capacity grid connection before April 30, 2026. This project has clear requirements for the team configuration of bidders, with a minimum of 18 personnel for project management, and a requirement for two 50MW or above photovoltaic power generation EPC projects.

The two agricultural photovoltaic complementary projects laid out by Datang Group in Chongqing have a total scale of 250MW. Among them, the 200MW project is located in Jiangjin District with a planned construction period of 366 days; The 50MW project is located in Tongliang District, with a planned construction period of 150 days. Both projects require bidders to have a corresponding scale of photovoltaic EPC performance in the past five years, with the 200MW project explicitly accepting consortium bidding.

Industry analysis points out that the projects subject to this centralized bidding have obvious demonstration significance. Photovoltaic desertification control projects in Xinjiang and Xizang combine the development of new energy with ecological governance, spontaneous self use projects in Inner Mongolia explore new modes of local consumption, and agricultural photovoltaic complementary projects in Chongqing maximize land use benefits. The promotion of these projects will not only drive the growth of China's photovoltaic installed capacity from 2025 to 2026, but also demonstrate the important supporting role of the photovoltaic industry in achieving the "dual carbon" goal.

It is reported that the bidding deadline for this round of bidding is concentrated in mid to late October 2025, and it is expected to attract many high-quality photovoltaic enterprises to participate in the bidding, laying a solid foundation for the construction of subsequent photovoltaic projects.
