The first distributed power generation project of ready-mixed concrete industry in Haikou was successfully connected to the grid

Recently, Haikou Meilan Plant was built in the west of China Construction, and the first distributed power generation project of ready-mixed concrete industry in Haikou was successfully connected to the grid.

With the transformation of energy structure and the emphasis on the development and utilization of renewable energy in China, the construction prospect of distributed photovoltaic power generation as a renewable energy technology is very broad. However, the difficulty hindering the large-scale development of distributed photovoltaic power generation is that distributed photovoltaic power generation requires sufficient construction land and sufficient lighting conditions for construction projects, and the return period of project investment is too long.

As a central enterprise in the concrete industry in Qiongzhou, China Construction West is committed to promoting the transformation of the industry and promoting the green and high-quality development of the industry. Therefore, Meilan Plant (Haikou Xijiantongfa Green Building Materials Co., Ltd.), which is located in the tropical monsoon region, is selected as the pilot plant and station, giving full play to the advantages of the preferential policies of the free trade port and the geographical conditions of the plant and station, and using the existing silo and the vacant roof of the office roof for the construction of the photovoltaic project.

Because concrete supply belongs to all-weather operation, it inevitably consumes a lot of industrial electricity during the peak period, which brings a lot of load to the State Grid and produces a high peak electricity price difference. In order to stabilize the peak electricity price of the mixing station, the idle space of the silo and office roof of the mixing station is fully utilized. After connecting with the newly introduced charging piles in the plant station, the energy supply problem of the new energy loader and the new energy mixer in the plant station is solved, and the self-driving vehicles of the employees in the plant station can be charged. There are many typhoons in

Hainan region, and the project construction is facing greater pressure of project progress. China Construction Western Construction Meilan Plant set up a project special work leading group at the first time, defined the four stages of construction preparation, project promotion, security, closing and grid-connected, drew up a work list for each stage of key tasks, determined the time node, inverted schedule, wall chart operations, and successfully completed the project within 80 days. The project is expected to generate about 1.1656 million degrees of electricity annually. Compared with traditional thermal power, it can save 419 tons of standard coal annually, reduce emissions of 1162 tons of carbon dioxide, 35 tons of sulfur dioxide, 17 tons of nitrogen oxides and 317 tons of carbon dust, which is equivalent to planting 2066 trees for Haikou City every year. After the grid-connected construction of the

project, China Construction Western Construction also officially owns the first ready-mixed concrete station in Haikou City, which is built and connected to the grid for power generation. In the later operation, through the mode of "self-use, surplus power grid" to meet its own electricity demand, the additional power generation will be supplied to the surrounding enterprises, and the green transformation and development of the industry will be promoted with practical actions. Zhu Xiangyi, Secretary-General of

Hainan Concrete Association, said that the distributed photovoltaic power generation project was the first photovoltaic power generation project in Haikou City to be combined with the ready-mixed concrete industry, which had industry demonstration significance for promoting the green upgrading of the concrete industry and promoting the "double carbon" transformation of the free trade port.
