The importance of new energy industry investment and construction as a powerful booster of economic growth is self-evident. Recently, Dawu County Development and Reform Bureau issued the "Fourteenth Five-Year Plan for the Development of New Energy Industry." This plan is mainly to plan for the construction of new energy power sources and urban new energy transportation applications in Dawu County, which mainly includes: centralized and distributed photovoltaic power stations; onshore wind power plants; biomass energy applications; urban new energy public transportation And the layout of charging piles; the supporting project of urban warm residential renovation.

The document points out the overall development goals:

Solar energy: Relying on the roofs of large public buildings such as schools, governments, industrial and commercial plants, land combined with agriculture, and idle land, etc., the application of solar thermal and photovoltaics will be fully promoted in the construction of Dawu County.

Wind power: Make full use of the rich wind energy resources of Dawu County, continuously improve the level of wind power generation technology and equipment, accelerate the development of Dawu distributed wind power, and realize the large-scale and industrialization of wind power in Dawu County.

The proportion of new energy consumption continues to increase. By 2025, the installed capacity of new energy power generation will reach about 2 million kilowatts.

The scale of the new energy industry continues to grow. By 2025, the total output value of the county's new energy industry will strive to reach 4 billion yuan, and the industrial added value will strive to reach 2 billion yuan.

Specific target:

By the end of 2025, wind power projects have planned installed capacity of 1500MW, of which 758.4MW will be completed during the "13th Five-Year Plan" period, and 741.6MW will be installed during the "14th Five-Year Plan" period, which will be connected to the grid for power generation.

By the end of 2025, the planned installed capacity of photovoltaic projects is 1,000MW, which will be constructed and connected to the grid during the "14th Five-Year Plan" period. Among them, 800MW has been contracted for the project, and the project will be implemented with an installed capacity of 200MW.

The document also pointed out that the focus will be on the construction of clean energy sources such as wind power, solar energy and biomass, while supporting the development of pumped storage to fully promote the implementation of key energy development tasks in the 14th Five-Year Plan. Fully explore the application potential of new energy in cities and towns, and actively promote the comprehensive application of distributed new energy while intensively building new energy bases. Speed up the construction and increase the flexibility of peak-shaving power supplies, implement "clean replacement" efficiently, and achieve a utilization rate of more than 70% of renewable energy.

The document also gives a detailed introduction to the development ideas, development advantages, construction priorities and development layout of solar power generation in Dawu County.

(1) Development ideas

Ideas for solar development in Dawu County: Utilize contiguous mountains, wasteland and good grid access conditions to focus on building large-scale photovoltaic power stations; combine the development ideas of the State Council’s Poverty Alleviation Office and the Energy Bureau to actively develop centralized photovoltaic power stations, combined with recent large-scale public construction While the project develops distributed rooftop photovoltaic power stations, it also supports the development of poor household photovoltaic power stations in poverty-stricken areas to achieve precise poverty alleviation.

Use financial subsidies or preferential on-grid electricity prices to encourage social funds to invest in the construction of rooftop solar grid-connected photovoltaic power generation facilities as supplementary power sources for enterprise production and office electricity.

There are 34 photovoltaic power stations in the county, with a total installed capacity of 114.992MW. Among them, there is 1 centralized photovoltaic poverty alleviation power station with an installed capacity of 90MW, accounting for 78.3%; 6 multi-village joint construction power stations with an installed capacity of 21.75MW, accounting for 18.9%; 27 Liancun (including village-level) power stations with installed capacity The capacity is 3.242MW, accounting for 2.8%.

(2) Construction focus and development layout

According to the general map of the "Urban Master Plan of Dawu County", the construction of photovoltaic projects mainly uses wasteland and mountains. Under the premise of not changing the nature and use of land, or affecting the ecological environment, adopt the "single-site dual-use" model to develop photovoltaic power generation, agriculture and fishery production, improve the comprehensive utilization of land, develop a low-carbon economy, and promote energy conservation and emission reduction.

For small and medium-sized centralized photovoltaic power plants, the voltage level of 110kV and below is used for online consumption and local consumption, and for large-scale photovoltaic power plants, the voltage level of 220kV is used for external power supply.

Photovoltaic power station panels use 255W polysilicon components, of which 1 MW is a power generation unit. Each power generation unit is equipped with two 500kW inverters and one 1000kVA low-voltage side double split winding box transformer.

Photovoltaic power stations are located in 53 villages in 14 towns and townships in Dawu County. Involving Daxin Town, Chengguan Town, Dongxin Township, Xiadian Town, Yangping Town, Pengdian Township, Luwang Town, Sanli Town, Xincheng Town, Fangfan Town, Sigu Town, Xuanhuadian Town, Gaodian Township, High-speed Railway Test Area.

Investment estimate

Comprehensive analysis of the wind, solar, and biomass resource endowments of Dawu County, combined with the development of power, arranges the construction, access and power generation plans of new energy power stations year by year. As of 2025, the installed capacity of photovoltaic power plants is 1,000MW, the installed capacity of wind power projects is 1,000MW, the installed capacity of biomass is 350MW, and the annual output is 200,000 tons of bio-forming raw materials.

In order to achieve the "dual carbon" goal, the next step is to formulate more active new energy development goals in Hubei Province. As of 2025, the total investment is 30 billion yuan, of which 12 billion yuan is invested in photovoltaic power plant projects with 2 million kilowatts of installed capacity; 12.9 billion yuan is invested in wind power projects with 1 million kilowatts of installed capacity; and 1.8 billion yuan is invested in biomass energy development. New energy public transportation and charging pile construction invested 2 billion yuan; other supporting facilities (low-carbon trading platform, exhibition center and exchange training section) invested 500 million yuan; solar lighting and heating 500 million yuan.
