On December 10th, the world's largest surface floating photovoltaic power plant China Three Gorges Group Three Gorges New Energy Corporation Anhui Huainan 150 MW surface floating photovoltaic project formally connected to the grid for power generation.
The project is located in Panji District, Huainan City, Anhui Province. China Three Gorges Corporation Three Gorges New Energy Co., Ltd. uses the idle water surface in the coal mining subsidence area with a total investment of about 1 billion yuan. The total installed capacity of the project is 150 megawatts. Construction starts in July 2017. In May 2018, all grid-connected power generation will be realized. After completion, the annual power generation will be about 150 million kWh of clean electricity, equivalent to about 530 hectares of broadleaf forest plantation, saving about 53,000 tons of standard coal annually, and reducing carbon dioxide emissions by about 195,500 yuan. Ton, to reduce the deforestation of about 54,000 cubic meters, to meet the electricity needs of about 94,000 households in urban and rural areas.
During the construction of the project, China Three Gorges Group actively fulfilled the social responsibility of the central enterprises, fully exerted its advantages in technology, management, brand, talents and capital, utilized the abundant solar energy resources in Huainan, built a photovoltaic base combined with ecological management, and actively explored “fishing”. The "new model of light complementarity" has truly transformed the subsidence area into a green energy base. At the same time, it actively communicates with the local government to establish a new model of win-win cooperation between government and enterprises. Through project construction, the use of coal mining subsidence areas idle water, the annual rental cost of more than 2 million yuan, can make the original idle water produce sustained economic benefits To increase income for farmers; project construction, routine maintenance, and component cleaning also make heavy use of local idle labor, bringing continuous and stable jobs and benefits to local farmers. The construction of this project has become a livelihood project that will help local farmers shake off poverty and increase income.
Three Gorges Anhui Huainan 150 MW water surface floating photovoltaic project pays more than 25 million yuan a year, which can provide local governments with continuous and stable taxation, helping local governments to shift coal mining subsidence areas from “baggage” to “wealth,” and the industrial layout from “ Underground “turned to the ground” and changed the development mode from “black” to “green”, which played a good role in demonstrating the combined development of the comprehensive utilization of land and the new energy industry, led to the development of local economy, and realized the development of resource-based cities. The fundamental transformation.
The National Energy Administration promotes the integration of idle water surface in coal mining subsidence area with the development of new energy, promotes the green development of coal mining subsidence areas, and boosts and leads the national new energy development model. The project construction has also been highly valued and supported by the Anhui Provincial Party Committee and the provincial government. The provincial party committee and provincial government leaders highly appreciated the Three Gorges Group's construction of the world's largest floating photovoltaic power station using the coal mining subsidence area in Huainan City, and expressed that it would fully support the power station to become a fine engineering and business card project, and further promote Huainan City. Coal mining subsidence area comprehensive management, development and utilization, to explore a new development path.
According to Lu Chung, Secretary of the Party Group and Chairman of China Three Gorges Group, water surface photovoltaic is a new exploration of new energy development and one of the effective paths for the transformation and development of many resource-based cities. China Three Gorges Group has taken the lead in the deployment of surface photovoltaics in Huainan to explore and reduce the cost of photovoltaics. The effective measures to reduce the cost of operation and maintenance will lay a solid foundation for the promotion and application in the country in the future. It is necessary to strive to build this project into the world's largest, most technologically advanced, and highest-level water quality photovoltaic engineering project, and to sum up a set of reproducible water photovoltaic construction experience and technical specifications.
It is understood that, compared with traditional photovoltaic power plants, floating photovoltaic power plants will install photovoltaic power generation components on the surface of the floating body, with no use of land resources, reduce the evaporation of water, the floating body blocks the sun to inhibit the growth of algae, while water on the photovoltaic components Cooling and cooling cables can significantly improve power generation efficiency.
