Recently, "China Southern Power Grid's "14th Five-Year" Rural Power Grid Consolidation and Improvement Plan" was officially released. According to the "Planning", China Southern Power Grid Corporation plans to invest 187 billion yuan to basically build a safe, reliable, green, efficient and intelligent modern rural power grid by 2025, which will further promote the five southern provinces and regions including Guangdong, Guangxi, Yunnan, Guizhou and Hainan. Rural revitalization and new urbanization construction provide energy support.

The "Planning" requires that by 2025, the company's customers in rural areas will have an average annual power outage of less than 8 hours, the first-end voltage qualification rate of the distribution station area will reach 100%, the voltage qualification rate will not be lower than 99%, and the average distribution transformer capacity of rural households will not be less than 100%. Less than 2.5 kVA, the equalization index of urban and rural power supply services is less than 4.2, the reliability rate of power supply by county is not less than 99.8%, the voltage qualification rate is not less than 97.9%, and the per-household distribution transformer capacity is not less than 2 kVA . The equalization of power supply services in urban and rural areas is basically achieved, and the load growth in rural areas and the demand for safe and reliable power supply are fully met. The quality of power supply and service level are continuously improved, and the level of digital automation and intelligence is significantly improved. The rural power grid is observable, measurable and controllable, and rural distributed new energy sources are realized. The proportion of electric energy in rural energy consumption continues to increase.

The "Plan" clarifies the key contents of five aspects

Consolidate the achievements of a new round of transformation and upgrading of rural power grids, and improve the level of power security in key areas; accurately upgrade rural power grids to help upgrade and upgrade rural modern infrastructure; improve the level of rural electrification to serve agricultural and rural modernization and rural industrial upgrading and development; improve rural distributed New energy consumption capacity, promote the construction of a modern rural energy system; improve the level of rural power supply services, and achieve equal development of urban and rural power supply services.

At present, the "dual carbon" goal promotes the deep integration of green energy development and rural revitalization, and the formation of a green and diverse rural energy system is accelerating. "The company will combine the action of harnessing the wind in thousands of villages and villages and the action of illuminating thousands of households to promote the scientific planning and orderly development of new energy in rural areas, strengthen the effective connection between new energy projects and rural power grids, and achieve a renewable energy consumption rate of 95%. , so that the new energy in rural areas should be 'combined' and fully absorbed." The relevant person in charge of the company's planning department introduced. Taking distributed photovoltaics as an example, the company will focus on promoting the pilot work of distributed rooftop photovoltaics in 83 rural counties and districts in the southern region, do a good job in the calculation of the carrying capacity of the regional power grid, and promote the construction of supporting power grid projects. During the "14th Five-Year Plan" period, Meet the grid-connected demand for 22 million kilowatts of distributed photovoltaics.

With the continuous improvement of the income level and quality of life of rural residents, by 2025, the electricity consumption of the whole society in the rural areas of the five southern provinces will exceed 750 billion kWh, and the maximum load of the whole society will be about 130 million kWh. In order to further consolidate and improve the rural power grid, during the "14th Five-Year Plan" period, the company plans to build and expand 1,140 substations of 110 kV and below, and increase the substation capacity of 110 kV and below by 74 million kVA; build and expand distribution transformers 11.7 10,000 units, new distribution transformer capacity of 29 million kVA, and 380,000 kilometers of new and renovated lines.
