Recently, the construction preparation of a large-scale agricultural photovoltaic complementary power station on a rural land in Jiangjin, Chongqing has reached a critical milestone. With the announcement of the list of winning bidders, photovoltaic arrays will soon be installed on farmland in this area to achieve synchronous promotion of agricultural production and photovoltaic power generation, injecting new momentum into the local energy structure adjustment. The publicly announced project is the 300 MW Agricultural Photovoltaic Complementary Power Station Project of Dajing New Energy in Jiangjin District, Chongqing. The bidding subject is Dajing New Energy Co., Ltd. in Jiangjin District, Chongqing, which is affiliated with Dajing Investment Holdings.

Clear and concise project overview

The project is located in Jiangjin District, Chongqing, with an installed capacity of 300MW on the AC side and up to 480MWp on the DC side. The capacity ratio is set at 1:1.6. The project selects 666670 monocrystalline silicon modules with a power of 720W, and builds a supporting Shimen photovoltaic 220kV substation. At the same time, 12 35kV collection lines with a total length of 122.3km are laid, and a new 220kV transmission line is built to connect to Zhutuo 220kV substation. The overall project duration is set at 420 days, with ample construction time to orderly advance various processes such as civil engineering, equipment installation, and line installation.

Candidate quotation range announced

From the information released this time, the bidding unit prices of the three winning candidates range from 2.434 yuan per watt to 2.567 yuan per watt. The total bid price of Zhongji Guojian Tianjin Construction Engineering Co., Ltd. ranked first is 1168530000 yuan, corresponding to a unit price of 2.434 yuan per watt; The second place Jiangsu Yanang Electric Power Construction Co., Ltd. quoted 1182300000 yuan, with a unit price of 2.463 yuan per watt; The third place Jiangsu Bincheng Electric Power Construction Co., Ltd. quoted 1232000000 yuan, with a unit price of 2.567 yuan per watt. The clear pricing gradient among various companies fully reflects the current competitive situation in the photovoltaic EPC market.

The potential of agricultural light mode is highlighted

The project adopts a development model of complementary agriculture and photovoltaics, and the lower space of the photovoltaic panels can still be used for crop planting, achieving dual-use in one location. While generating clean electricity to support the dual carbon goals, we will also activate idle rural land resources and drive stable income growth for surrounding farmers.
