What impact will high temperature and typhoon have on power supply? How to promote the development of energy storage industry?

Recently, the executive meeting of the State Council made a special deployment for the work of ensuring the safety and power supply of energy and power during the summer peak. On July 26, the State Council Information Office held a regular policy briefing of the State Council to introduce the situation of ensuring energy and power supply during the summer peak. Let's see together——

Q1

Q: How will the National Development and Reform Commission implement the requirements of the National Standing Committee and ensure the safety and supply of energy and electricity?

A: At present, the peak summer season has entered a critical period. The economic recovery is superimposed with high temperature weather, and the complexity and difficulty of ensuring energy and power supply security have increased significantly. The National Development and Reform Commission will conscientiously implement the spirit of the important instructions of General Secretary Xi Jinping, and in accordance with the deployment requirements of the Party Central Committee and the State Council, give full play to the role of the inter-ministerial coordination mechanism for the guarantee of coal, electricity, oil and gas transportation, and make every effort to do a good job in energy and power with the sense of responsibility of "always rest assured" Safe and secure work.

The first is to continue to strengthen fuel supply guarantees. Strengthen the supervision of the performance of medium and long-term power coal contracts, increase the supply of natural gas for peak power generation, and ensure that the primary fuel demand is fully met.

The second is to urge all types of generating units to send out as much as possible. Ensure that the thermal power output remains at a historically good level, optimize the operation mode to maintain the peak output of hydropower, and promote the multiple generation and multiple use of nuclear power, wind power, and solar power.

The third is to strengthen scheduling and promote mutual aid between provinces. Give full play to the advantages of unified dispatching of large power grids, do a good job in ensuring power supply in key areas during important periods, organize cross-provincial and cross-regional mutual assistance, and improve the country's ability to ensure power supply security.

The fourth is to make emergency plans based on bottom-line thinking. Guide all localities to dynamically optimize and adjust demand-side load management plans according to actual conditions, and strive to use them as little as possible while ensuring that people's livelihood and key energy consumption will not be affected under extreme conditions.

Q2

Q: What impact will high temperature, typhoon and other weather have on energy supply and power facility operation?

A: Hot weather is a common concern for everyone. Since the beginning of this year, my country's high-temperature heat waves have occurred early, with a wide range, overlapping regions, and strong extremes. There have been 6 regional high-temperature weather processes across the country. High temperature weather will have an impact on energy supply from both supply and demand aspects. On the one hand, from the load side, high temperature weather will lead to an increase in the production and living electricity load of the masses, which will put pressure on the energy supply guarantee. On the other hand, from the perspective of power supply, high temperature and little rain will lead to insufficient output of hydropower generation, which will affect the supply of water storage power generation.

In addition to high temperature weather, meteorological disasters such as typhoons will also affect the safe operation of power facilities and have some adverse effects on energy supply. The meteorological department and the energy management department maintain close communication and cooperation, timely report the latest forecast and forecast, and take effective measures to minimize the impact of weather on energy supply. According to the forecast of the Central Meteorological Observatory, this year's No. 5 typhoon "Dusuri" may land on the coast from Jinjiang, Fujian to the junction of Fujian and Guangdong from the morning to the morning of July 28, and the maximum wind force near the landing center can reach magnitude 14-15. After the 28th, "Du Su Rui" will go deep into the inland and northward, and will further affect the eastern part of our country. The typhoon process is generally conducive to offshore wind power generation, but it is still necessary to pay attention to the impact of strong winds on the safe operation of wind turbines before and after the typhoon lands. It is recommended that Fujian and Guangdong should make preparations for wind power cut-off in advance. In addition, strong winds and heavy rainfall may have a destructive impact on power facilities such as photovoltaic power plants, transmission lines, and substations. It is recommended to do a good job in the maintenance and operation monitoring of power facilities in advance.

Q3

Q: What measures will be taken to regulate the demand side management of electricity?

A: Power demand-side management refers to strengthening the management of power consumption in the whole society. Through the comprehensive adoption of reasonable and feasible technical, economic and management measures, it can realize "peak shaving and valley filling" and relieve the pressure of peak power supply. It is an international common response to peak load. The most economical means.

The National Development and Reform Commission and relevant parties organized the revision of the "Power Demand Side Management Measures", and the public consultation has been completed, and the publication and distribution will be accelerated.

In the next step, we will focus on three aspects of work:

The first is to increase the development and utilization of demand-side resources. In recent years, electric vehicles, new energy storage, distributed power sources, virtual power plants and other new entities and business forms on the demand side have emerged. We encourage various business entities to actively participate in market-oriented demand response and obtain corresponding benefits by independently reducing electricity loads. It is estimated that by 2025, the demand response capacity of each province will reach 3%-5% of the maximum power load; among them, the provinces with the peak-to-valley difference rate of the maximum annual power load exceeding 40% will have a demand response capacity of more than 5%.

The second is to improve demand response incentive policies and market mechanisms. On the basis of carefully summarizing the exploration and practice in some places in recent years, we will further improve the electricity price policy and market mechanism, guide power users to optimize the way of electricity consumption, and actively cut peaks and fill valleys.

The third is to continue to promote the saving of electricity in the whole society. Work with relevant departments to actively promote energy-saving technologies, promote energy-saving renovations, and optimize energy consumption structures in the fields of industry, construction, and transportation. Guide enterprises, institutions, communities, and families to actively practice green and low-carbon production and lifestyles, create a social trend of saving electricity and rationally using energy, and help build a conservation-oriented society.

Q4

Q: How to promote the development of the energy storage industry?

A: Energy storage is the key technology and basic reserve to promote the large-scale development and consumption of new energy and improve the safe and stable operation of the power system. It is of great significance to further promote the green and low-carbon transformation of energy and help achieve the goal of carbon neutrality. There are many energy storage technology routes, including conventional pumped storage, and now emerging electrochemical energy storage, compressed air energy storage and other technical routes. We attach great importance to the innovation and industrial development of various energy storage technologies. In terms of new energy storage, since 2021, the National Energy Administration, together with relevant departments, has successively issued the "Guiding Opinions on Accelerating the Development of New Energy Storage", "Implementation Plan for the Development of New Energy Storage during the 14th Five-Year Plan" and "New Energy Base Power Transmission Configuration". A series of policy documents such as "Technical Guidelines for New Energy Storage Planning" put forward overall requirements, development goals and relevant information on planning and configuration of new energy storage, project management, dispatching and utilization, market mechanism, safety management, personnel training and standard system. Key task arrangement. It provides an important foundation for governments at all levels and industry enterprises to promote technological innovation, application demonstration and industrial development.

In recent years, driven by the demand for large-scale development and consumption of wind power and photovoltaic power generation, and with the support of relevant industrial policies, my country's new energy storage has developed rapidly, and the installed capacity has grown rapidly. As of the end of May this year, the installed capacity of new energy storage has exceeded 12 million kilowatts, and the emphasis on new energy storage has continued to increase across the country. At present, more than ten provinces are carrying out pilot demonstrations of new energy storage, driving the rapid development of various technical routes such as lithium-ion batteries, flow batteries, and compressed air energy storage, and the related industrial chain system is also constantly improving.
