Recently, the 500 kV transmission project from Hongyanhe Nuclear Power Station to 500 kV Wafangdian Substation in Dalian, Liaoning Province is stepping up construction, and it is planned to be put into operation at the end of April. This project is an important project to implement the goal of peak carbon dioxide emissions and carbon neutrality. It will further optimize and improve the 500 kV grid structure in Dalian, meet the needs of six units in Hongyanhe Nuclear Power Station, replace 2.28 million tons of standard coal annually, and reduce carbon dioxide emissions by more than 6.25 million tons.

During the '14th Five-Year Plan' period, Liaoning Electric Power of State Grid accelerated the construction of new power system, actively served the green and low-carbon transformation of energy, planned to build more than 300 substations with a capacity of 60 million KVA and a line length of 13,000 kilometers, focusing on strengthening the power grid construction in areas with fast load development in central and southern Liaoning and areas with rich new energy in northwest Liaoning, and serving Liaoning's all-round revitalization and the realization of the 'double carbon' goal.

To speed up the project landing and key breakthroughs, State Grid Liaoning Electric Power has rolled out the 'Double Carbon' task list and power grid planning, promoted the coordinated development of power grids at all levels as a whole, and built a strong platform for clean and efficient utilization of coal, water, nuclear, wind and other energy sources.

In 2021, Liaoning Electric Power of State Grid increased 'four new and four expanded' 500 kV substations to enter the '14th Five-Year Plan' power grid planning; The 500 kV Yongan Substation, which was put into use in the new energy delivery, opened up a green energy 'highway' from the northern Liaoning light resource-rich area to the central Liaoning load center.

In 2022, Liaoning Electric Power of State Grid fully promoted the demonstration of the first batch of 7.25 million kilowatts wind power project access system overall plan, started the feasibility study of the supporting project ahead of time, simplified the approval process of access to the power grid by 2 items, and reduced it to 10 working days, so as to provide better power services for the early connection of new energy. Accelerate the preliminary work of 500 kV key projects such as Fuxin Toyota Boost, Chaoyang Lizhou Expansion, Huludao Shaheying Expansion, etc., and comprehensively improve Liaoning Power Grid's capacity to absorb new energy and optimize the allocation of resources.

Gao Kai, head of Liaoning Power Dispatching and Control Center of State Grid, said: 'With the gradual completion of 4.8 million kilowatts of low-cost new energy planning projects in the province, the installed capacity of new energy will grow rapidly again. It is estimated that the wind power generation of Liaoning Power Grid will increase by 16.1% year-on-year, and the photovoltaic power generation will increase by 21.1% year-on-year. '

At the same time, Liaoning Electric Power of State Grid actively serves the high proportion of new energy consumption and high-quality development, completes the grid-connected service of new energy, calculates the consumption capacity of new energy on a rolling basis, strengthens the dispatching and operation management of new energy, and conducts research on key technologies of new power systems.

In order to realize the early grid connection and power generation of new energy, Liaoning Electric Power of State Grid started the online service process of new energy grid connection, and updated the defect rectification situation and process node information of the stations before grid connection in real time; Compile the new energy grid-connected service guide and manual, standardize the professional management requirements of various departments, clearly standardize the professional management standards and acceptance requirements of provincial and local power companies, and strengthen risk prevention and control.

In addition, Liaoyang Power Supply Company actively docked Gongchangling Urban and Rural Public Transport Integration Project, accelerated the construction of charging pile supporting facilities, met the electricity demand of 76 charging parking spaces, promoted the green, environmental protection and intelligent traffic construction in Gongchangling District, and created a new green traffic demonstration area. 'The electricity service of the power supply company has accelerated the opening operation of all electric buses, and made the whole district bid farewell to the history of no buses. Urban buses are gradually entering a new era of green energy conservation and emission reduction.' Yu Hailiang, head of Liaoyang Gongchangling District Transportation Bureau, said.

At present, electric vehicle charging stations in Liaoning cover all cities and some expressway service areas. State Grid Liaoning Electric Power and related industrial units have built 375 charging stations, totaling 2,650 charging piles; The annual charging capacity exceeds 25 million kWh, and the annual alternative fuel exceeds 80,000 liters. At the same time, State Grid Liaoning Electric Power will also build 1,000 charging piles in the county, complete the layout of vehicle networking platform to rural areas, make a good layout plan of charging and replacing power network, and form an efficient, stable and sustainable vehicle network interactive business model and market operation mechanism to help realize green and low-carbon travel.

It is understood that in 2022, State Grid Liaoning Electric Power will continue to promote the electrification development of electric vehicles, port shore power, etc., dig deep into the replacement potential of industrial production kilns and boilers, speed up the construction of rural electrification upgrading projects, and promote clean heating 'coal to electricity'. At the same time, it will promote the energy efficiency of Liaoning's whole society, and strive for the electric energy to account for 24% of the terminal energy consumption, and add more than 30 billion kilowatt-hours of electric energy instead of electricity.

State Grid Liaoning Electric Power Co., Ltd. will also actively serve the development of rural clean energy, promote the revolution of comprehensive energy production and consumption, change the rural energy consumption mode and improve the comprehensive energy utilization efficiency; Further strengthen the power supply capacity of rural power grid, improve the grid structure, promote the access of distributed power sources and the consumption of new energy, and help the sustainable development of rural distributed new energy.
