Recently, two units under China Energy Engineering Group have achieved outstanding results in the bidding for photovoltaic power generation projects. China Energy Engineering Group Guangdong Thermal Power Engineering Co., Ltd. plans to win the bid for the first phase 500MW EPC project of the Fuping 1GW photovoltaic power generation guarantee grid connection project. China Energy Engineering Group Hunan Thermal Power Construction Co., Ltd. plans to win the bid for the construction and equipment bundling procurement project of the 500000 kW low-carbon transformation photovoltaic project in Yili Gongliu Industrial Park of Huaneng Xinjiang Gongliu New Energy Company. The total bidding price for these two projects reached 2.288 billion yuan.  

The construction site of the Fuping 1GW photovoltaic power generation guarantee grid connection project is in Fuping County, Baoding City, Hebei Province, including Shijiazhai Township, Datai Township, and Taiyu Township. The project aims to construct a photovoltaic power station with a rated capacity of 500MW on the AC side and 600MWD on the DC side. A 220KV booster station will also be built to support the project, which will include two 250MVA main transformers. At the same time, an energy storage system with a capacity of 100MW and a storage duration of 1400MWh needs to be built. Electricity needs to be transmitted through a 25 kilometer long line to achieve grid connection.  

The bidding content for this project is very comprehensive. We need to construct a photovoltaic field area, responsible for the booster station and energy storage system, as well as laying collection and transmission lines. The preliminary design and construction drawing design of all these parts need to be done, and the completion drawings need to be prepared later. The company is responsible for purchasing various equipment and materials, transportation, and daily management. All building installations, equipment debugging, and trial runs must also be completed. The project also includes communication connection, system debugging, and grid acceptance. The winning company shall also carry out maintenance and upkeep during the quality assurance period, assist in handling grid connection procedures, participate in special acceptance and corresponding coordination work. These tasks are very specific and require the company to have strong management and technical capabilities.

According to the bidding information, the EPC (Engineering, Procurement, and Construction) project for the first phase of the Fuping 1GW Photovoltaic Power Generation Guarantee Grid Connection Project, with a total capacity of 500MW, is ranked first by China Energy Engineering Group Guangdong Thermal Power Engineering Co., Ltd. The winning bid amount is 1890551997.64 yuan. China Gezhouba Group Electric Power Co., Ltd. ranks second with a bid amount of 1935022651.15 yuan. China Energy Engineering Group Zhejiang Thermal Power Construction Co., Ltd. ranks third with a bid amount of 1884241838.22 yuan.  

Another project, the low-carbon transformation photovoltaic project of Huaneng Xinjiang Gongliu New Energy Company Yili Gongliu 500000 kW Industrial Park, involves construction and equipment bundling procurement, located in Yilegadai Village, Gongliu County, Ili Kazakh Autonomous Prefecture, Xinjiang. This village is about 90 kilometers away from Yining City and only 9.8 kilometers away from Gongliu County. The planned photovoltaic capacity for the project is 500MW, with a capacity ratio of 1.17. The project also requires the construction of a new 220kV collection station. The gathering station is planned to have three main transformers, each with a capacity of 240MVA. Only two of them will be built in this phase, and the remaining locations will be reserved for future expansion. In addition to the main transformer equipment, it is also necessary to construct an energy storage facility with a capacity of 50MW and a storage time of 100MWh. All electricity is transmitted to the 220kV Gongliu substation through a 220kV line. This route is 25 kilometers long.  

The winning bid for this project was ranked first by China Energy Engineering Group Hunan Thermal Power Construction Co., Ltd., with a bid amount of 398203953.91 yuan. China Aneng Group Third Engineering Bureau Co., Ltd. ranks second with a bid amount of 429700540.93 yuan. China Energy Engineering Group Northeast Electric Power First Engineering Co., Ltd. ranks third with a bid amount of 411570946.19 yuan. Through these two projects, it can be seen that the company needs to complete a lot of work, including site selection, design, procurement, transportation, construction, commissioning, maintenance, etc. The winning bidders are China Energy Engineering Group Guangdong Thermal Power Engineering Co., Ltd. and China Energy Engineering Group Hunan Thermal Power Construction Co., Ltd. The winning bid amount and bidding amount are displayed according to the announcement and have not changed.

The bidding prices of the top three bidding companies have been made public for each project. The project content is rigorous, the work requirements are meticulous, and all aspects must be executed according to regulations. These photovoltaic power generation projects have a large construction scale and numerous tasks. It is not only necessary to manage the construction work well, but also to ensure the safety and reliability of equipment procurement and energy storage facilities. The company needs to coordinate design and construction with power grid connection, and strictly promote construction according to project requirements. Every step must ensure quality. The bidding process is open, the participating companies are orderly, and the bidding results are transparent. The project construction has a promoting effect on the local energy development and can also promote the progress of the new energy industry.Editor/BIian Wenjun
