From October 19 to 21, the Bureau of Ecology and Environment of Wanzhou District of Chongqing issued a public announcement on the acceptance of environmental impact assessment of two major photovoltaic projects. The total installed capacity of the two photovoltaic projects is 222MW , with a total investment of over 900 million yuan .
Guoneng Chongqing Wanzhou Longsha Photovoltaic Project
On October 21, the Bureau of Ecology and Environment of Wanzhou District of Chongqing issued an announcement on the acceptance of the EIA documents of Guoneng Chongqing Wanzhou Longsha Photovoltaic Project.
According to the announcement, the project is planned to be implemented in Longsha Town, Xiangshui Town and surrounding villages and towns in Wanzhou District of Chongqing, and will be constructed by Chongqing Wanzhou Wanxiang Longyuan New Energy Co., Ltd. with a total installed capacity of 172 MW. There are 43 photovoltaic power generation units in
the project, including 25 6.15 MWp, 7 5.62 MWp, 4 4.95 MWp, 4 3.08 MWp and 3 1.87 MWp photovoltaic arrays. The main equipment adopts 650Wp monocrystalline silicon double-sided photovoltaic modules and 460 kW string inverters .
Every 28 PV module strings are a PV string, and every 33 ~ 34 PV strings are connected to a 460 kW string inverter, totaling 374 inverters. Each photovoltaic sub-array is boosted to 35kV by one box-type transformer, and multiple transformers are connected in parallel at the high-voltage side to form a combined unit to form a circuit of collector line, with a total of 7 circuits of 35kV collector lines connected to the booster station.
The photovoltaic power generation unit is mainly composed of photovoltaic array, string inverter, box-type transformer, etc.
This project covers a total area of 3131432.5 m ², with a total investment of 710.48 million yuan . The total duration of the
project is planned to be 30 months.
Guoneng Chongqing Wanzhou Yanshan Agriculture (Forestry, Fishery) Light Complementary Project
On October 19, the Bureau of Ecology and Environment of Wanzhou District of Chongqing issued a public announcement on the acceptance of the EIA of Guoneng Chongqing Wanzhou Yanshan Agriculture (Forestry, Fishery) Light Complementary Project.
According to the announcement, the project is located in Yanshan Township, Wanzhou District, Chongqing, and is constructed by Guoneng Chongqing Wanzhou New Energy Development Co., Ltd. with a total investment of 19121 0.14 million yuan . The main construction contents of
the project include photovoltaic field area, 35kV collector line and 110kV booster station. There are 17 array areas in the photovoltaic field area of
the project, with a total land area of about 89,6000m ². 660Wp N-type monocrystalline silicon photovoltaic modules and 320kW string inverters are used. The fixed bracket/flexible bracket installation method is adopted; Installed capacity of PV area is 65.0166 MWp and rated capacity is 50 MW .
The project plans to adopt 17 Hua-style box-type transformers with a single capacity of 1600kVA, 2500kVA and 3200 kVA respectively, and design 12 photovoltaic power generation units with a rated capacity of 3.2M W, 4 photovoltaic power generation units with a rated capacity of 2.5M W and 1 photovoltaic power generation unit with a rated capacity of 1.6M W. The construction period of the
project is 12 months.
