As of the end of April, the cumulative installed capacity of wind power and photovoltaic power generation in the country exceeded 1.1 billion kilowatts-
Multi-measures to do a good job of new energy consumption
The National Energy Board recently issued a "notice on new energy consumption work to protect the high-quality development of new energy" (hereinafter referred to as "Notice"), clear to accelerate the construction of new energy supporting power grid projects, and actively promote the system to enhance the ability to regulate the coordinated development of the network and sources and other key tasks. Industry sources said that the "Notice" to improve the new energy utilization management mechanism, support the new energy high-quality development, accelerate the construction of a new type of power system and a new type of energy system, and promote the realization of the "dual-carbon" goal is of great significance.
Science-based targeting of new energy utilization rates
The relevant person in charge of the National Energy Administration (NEA) introduced that the NEA has continued to do a good job of new energy consumption, vigorously promote the construction of cross-provincial and regional transmission corridors, strong backbone grids and distribution grids, and continuously improve the regulation capacity of the electric power system, expand the new energy market-oriented trading of power, and promote the rapid development and efficient utilization of new energy.In 2023, the national utilization rate of wind power was 97.3%, and that of photovoltaic power generation was 98%, maintaining a high level. Accompanied by the new energy development to further speed up, as of the end of April this year, the national wind power, photovoltaic power generation cumulative installed capacity of more than 1.1 billion kilowatts, year-on-year growth of about 38%, a substantial increase in the demand for consumption.
At the same time, although the national new energy utilization rate has continued to remain at a high level above 95% since 2019, the pressure on consumption has been apparent in some areas and at some times.
"At present, the system stock of regulation capacity has been basically tapped, the need to add the construction of a large number of new energy storage and other regulation resources, the economic cost is larger, pushing up the cost of energy for the whole society, is not conducive to the sustainable development of new energy on a large scale." Power Planning and Design Institute relevant experts analyzed. Taking into account this factor, the "Notice" puts forward "scientific determination of new energy utilization targets" "part of the resource conditions in the region can be appropriately relaxed new energy utilization targets, in principle, not less than 90%".
The aforementioned experts said that, from the perspective of system optimization to coordinate the development and consumption, appropriate relaxation of resource conditions, new energy power generation cost is lower, the system cost of consumption of new energy utilization target in the region, can be for the development of new energy to leave more space.
Promoting the construction of new energy supporting power grid project
With the large-scale integration of new energy into the grid, the demand for supporting grid construction has risen sharply, and it is necessary to speed up the planning and construction of supporting grids and optimize the process of connecting to the grid.
The Notice proposes to accelerate the construction of new energy supporting grid projects. On the one hand, strengthen planning and management. 500 kV and above supporting grid projects, the annual organization of the national power development plan within the project adjustment, and for the national layout of large-scale wind power photovoltaic bases, watersheds, water and wind integration bases and other key projects to open up a "green channel" to speed up the promotion of a number of new energy supporting grid projects to the rules. On the other hand, accelerate project construction. Energy authorities at all levels, in conjunction with grid companies to establish a new energy supporting grid projects have been included in the planning list, under the premise of ensuring security to accelerate the advance, approval and construction work. In addition, the requirements to optimize the process of connecting to the grid, grid companies should take the initiative to provide services for new energy access to the grid, simplify the review process, and further improve efficiency.
The Notice makes it clear that it will actively promote the upgrading of the system's regulating capacity and the coordinated development of networks and sources. Provincial energy authorities should be based on the new energy growth scale and utilization rate target, to carry out power system regulation capacity demand analysis, according to local conditions to formulate the regional regulation capacity enhancement program. At the same time, to carry out coal power unit flexibility transformation effect, various types of energy storage facilities regulation performance, load-side regulation resources to participate in the system regulation scale and confidence of the comprehensive assessment. In view of the lack of coordination and connection between the planning and construction of some new energy and power grid projects, it is requested to accelerate the planning and construction of supporting power grids while arranging the construction of new energy projects in an orderly manner, scientifically arranging the development and layout of centralized new energy, the commissioning schedule and the direction of consumption in combination with the capacity to consume new energy, and reasonably arranging the development and layout of distributed new energy, and strengthening the synergy between the new energy and the construction of the supporting power grids.
Regularization of consumption monitoring and analysis
Standardizing the statistical management of new energy consumption data to scientifically reflect the real level of new energy consumption and utilization is also a key part of promoting better consumption of new energy.
On the one hand, the caliber of new energy utilization statistics should be unified. The Notice makes it clear that power generation and grid enterprises should strictly implement the statistical methods for wind farms, PV power stations' available power generation and restricted power as stipulated in the Measures for Monitoring and Statistical Management of Wind Farm Utilization and Measures for Monitoring and Statistical Management of Photovoltaic Power Station Consumption issued by the National Energy Administration, and that the new energy utilization rate shall be calculated according to the case of restricted power for system reasons only. "This can exclude the impact of special factors such as irresistible factors, grid connection debugging, planned maintenance, and improper decision-making in market-based trading, and more scientifically reflect the real level of new energy consumption and utilization." Experts from the General Administration of Electric Power Planning and Design said.
On the other hand, the verification and disclosure of new energy consumption data has been strengthened. Power generation and grid enterprises shall report to the National New Energy Power Consumption Monitoring and Early Warning Center the new energy grid-connected scale, utilization rate and available power generation, actual power generation, restricted power, restricted power for special reasons, and other basic data. Power grid enterprises at all levels shall disclose basic data such as utilization rate and available power generation, actual power generation, restricted power generation, restricted power generation for special reasons, etc., to the wind farms and photovoltaic power stations within the scheduling range of their power dispatching agencies on a monthly basis.
The relevant person in charge of the National Energy Board said that it will carry out monitoring, analysis and supervision of new energy consumption on a regular basis, and carry out monthly consumption monitoring, semi-annual analysis and consultation, and annual consumption assessment. Strengthen the supervision of new energy consumption measures across provinces, and urge the relevant units to cancel unreasonable restrictive measures.
