In order to accelerate the implementation of the carbon peak and carbon neutral action plan, build a new type of power system. On August 6, the integration and development of Shaanxi Power Grid has a new timetable. On the same day, the State Grid Shaanxi Electric Power Co., Ltd., jointly funded by the State Grid Co., Ltd. and the Shaanxi Provincial People's Government, was established, and Shaanxi Power Grid took a solid step towards high-quality development.

This is a milestone in the development history of Shaanxi Power Grid. It will promote the unified planning, construction and operation management of Shaanxi Power Grid, promote Shaanxi’s energy transformation, accelerate the construction of a new power system with new energy as the main body, and serve Shaanxi’s new era of catching up and surpassing, and helping to achieve carbon Reaching peaks and carbon neutral targets accumulate energy.

Implement the new development concept and stimulate the multiplier effect of high-quality development

Where is the "new" of the new Shaanxi company? What can it bring? 100 billion yuan is the amount of power grid investment that the new Shaanxi Company strives to complete during the "14th Five-Year Plan" period. As an important infrastructure, power grid construction is essential to promote economic growth and serve to improve people's livelihood. During the period from the 11th Five-Year Plan to the 13th Five-Year Plan, State Grid Shaanxi Electric Power invested a total of 97.7 billion yuan to build a strong smart grid. At present, Shaanxi Province has formed a "two vertical and two loops" 750 kV backbone grid. The 330 kV power grid surrounds load centers such as cities and industrial areas. Flexible and reliable operation.

In addition, the company has comprehensively improved the overall level of rural power grids directly supplied to counties in Shaanxi through a new round of rural power grid transformation and upgrading. At the end of 2020, the power supply reliability rate of the regional rural power grid under the direct management of State Grid Shaanxi Electric Power was 99.856%, the comprehensive voltage qualification rate was 99.796%, and the average household distribution transformer capacity was 2.48 kVA.

The establishment of the new Shaanxi company is conducive to better realizing the effective connection between the power grid planning and the economic and social development plan of Shaanxi, solving the problems of uncoordinated, unbalanced, and insufficient power grid development; conducive to overall coordination and strengthening of Shaanxi power grid construction and avoiding inefficient power grid investment And repeated construction, give full play to the advantages of scale and collaborative management, and reduce coordination and management costs. After the Shaanxi electric power management system is straightened out, the investment channels in the retail areas in the past will be further smoothed. The investment intensity and construction standards of the power grids in the retail counties will be in line with the counties directly managed by the State Grid Shaanxi Electricity, which will contribute to economic and social development. Provide strong protection.

The power grid is stronger, the service is better, the business environment is better, and the enterprise development is more "vigorous"... From speeding up the construction of the power grid to improving the service level to promoting the high-quality development of the enterprise, the establishment of the State Grid Shaanxi Electric Power Co., Ltd. will Promote complementary advantages, stimulate the multiplier effect, and achieve win-win cooperation.

Build a new development pattern to serve the carbon peak and carbon neutral goal

On the day when the new Shaanxi company was established, the second UHV power transmission channel in Shaanxi-Northern Shaanxi-Hubei ±800 kV UHV DC Project (hereinafter referred to as the Northern Shaanxi-Hubei Project) started power transmission, and the abundant resources in Northern Shaanxi were transformed into Strong electric energy, went straight to the land of Central China.

"My family lives on a high slope of loess, and the strong wind blows from the slope... My family lives on a high slope of loess, and the sun walks across the slope." The "gale" and "sun" sung in the song are for nature to northern Shaanxi. Regional gifts.

The North Shaanxi Energy and Chemical Industry Base is one of the four major bases in Shaanxi Province. Northern Shaanxi has 270 billion tons of coal reserves, accounting for 12% of China's. It is rich in wind and solar resources. It is estimated that the installed capacity of new energy power generation will reach more than 40 million kilowatts by the end of the "14th Five-Year Plan" period. Hubei's economic and social development momentum is strong, and the demand for energy and electricity is huge, but the primary energy resources are relatively scarce, and the seasonal characteristics of hydropower are obvious.

As a key project to promote the development of the western region and the rise of the central region, the northern Shaanxi-Hubei project has an annual electricity transmission capacity of 40 billion kwh, broadening the "electric highway" for the large-scale development and utilization of clean energy in northern Shaanxi, and promoting energy development and electric power in northern Shaanxi. Large-scale delivery to meet the electricity demand in Central China.

Shaanxi New Energy is growing rapidly. As of the end of June, the new energy grid-connected installed capacity in the State Grid Shaanxi power grid reached 17.95114 million kilowatts, a year-on-year increase of 41.56%; from January to June, new energy power generation was 15.192 billion kilowatt-hours, a year-on-year increase of 54.73%, and the new energy utilization rate was 97.2%. In order to implement the carbon peak and carbon neutral goals, Shaanxi Province’s "14th Five-Year" development plan puts forward that the total installed capacity of renewable energy in 2025 will reach 65 million kilowatts.

To achieve large-scale grid connection of new energy, but also to maintain a high level of utilization of new energy, how to safely and efficiently receive and send out more new energy power generation is a key issue. From the supply side, new energy will gradually become the main body of installed capacity and electricity; from the user side, a large number of producers and consumers of electricity generation and consumption have emerged in large numbers; from the power grid side, the AC-DC hybrid power grid is still the dominant resource optimization configuration Power, the distribution network has become an active grid and interconnected with large power grids and coordinated operation. The role of the grid’s hub platform has become more prominent. It has become an urgent need to build a new type of power system with more powerful functions, more flexible operation, and more resilient.

Continue to increase investment in power grids, strengthen the construction of transmission channels and UHV transmission channels in the province; adhere to customer-centricity, improve the level of equalization of power supply services; expand the breadth and depth of power substitution, and improve the level of electrification in the province; establish network-wide coordination, The management system of active defense and intelligent decision-making, from the perspective of overall optimization, comprehensively enhance the overall mutual supply and mutual aid ability and anti-risk ability of the power grid... With the new Shaanxi company as the carrier, the company will serve the economic and social development of Shaanxi in a wider range. There will be more, and the intensity will be stronger. ,
