on April 1, the core benchmarking project of the country’s second batch of “shago wilderness” large-scale wind power photovoltaic bases built by China energy construction Gezhouba company, the world’s largest single-phase construction of “light and heat storage” integrated project-China energy construction Hami “light (heat) storage” 1500MW base project photovoltaic zone officially started.
The project is located in the Cha Ha Spring area 60 kilometers northeast of Santanghu Town, Barkol County, Hami City, Xinjiang, with a total area of about 50000 mu. The project adopts the integrated collaborative mode of “photovoltaic + photothermal + thermal storage” to build 1350MW photovoltaic and 150MW photothermal, and to build 1 heat absorption tower, 2 220 kV boost collection stations and transmission lines. China Energy Construction Gezhouba No.3 Company has undertaken the construction of bid section 4 of the photovoltaic area of the project. The main construction content is 406.97MWp photovoltaic square array area construction and installation project, covering the whole process of site clearance, site leveling, construction contracting, project grid connection, acceptance and standard creation.
As the core carrier of China’s photothermal power generation technology innovation, the project focuses on the extreme environmental pain points of the Gobi and achieves a number of key breakthroughs. The photothermal part of the project is equipped with an 8-hour high-temperature molten salt heat storage system. Through the combined operation of photothermal and photovoltaic, with intelligent dispatching system and “two-way energy storage” mechanism, the all-weather power supply mode of “photovoltaic power generation in the daytime and photothermal compensation at night” can be realized, and the deep coupling of thermal storage photothermal and photovoltaic can be realized, so that two different solar power stations can shine in the Gobi Desert at the same time, convert ever-changing solar energy into “100 percent green power” with stable output to create an adjustable grid-friendly power model project.
After the completion of the project, the annual power generation is expected to be about 3 billion kilowatt-hours, of which about 2.8 billion kilowatt-hours are photovoltaic power generation and about 0.2 billion kilowatt-hours are photothermal power generation. It can save 868000 tons of standard coal and reduce carbon dioxide emissions by 2.256 million tons each year, with significant ecological benefits. In the next step, the project department will closely follow the time limit target, scientifically coordinate the allocation of resources, strengthen the construction organization and management, strictly control the safety and quality barriers, ensure the efficient and orderly progress of various construction tasks, and make every effort to build the project into a safe, reliable, green and low-carbon boutique project.
