A healthier new energy power generation industry can better help the "double carbon" reach the standard
Representative members talk about science and technology supporting economic stability and long-term development

To achieve the goal of peak carbon neutrality, promoting the green and low-carbon development of electricity is an important part.
This year's two sessions, many deputies have set their sights on this field, and put forward a series of constructive opinions and suggestions on promoting the healthy development of the new energy power generation industry.
An important force in the transformation of the energy structure
"Constructing a new power system with new energy as the main body is an important task in the process of achieving carbon peaking and carbon neutrality in my country. New energy power generation will become the main force of future power supply." Zhang Tianren, deputy to the National People's Congress and chairman of Tianneng Group Express.
According to the data disclosed by the National Energy Administration at the end of January this year, my country's renewable energy power generation has been growing steadily.
"In the process of large-scale application, the level of photovoltaic power generation, wind power and other renewable energy power generation technologies has been continuously improved, and the cost has continued to decline. The grid parity without subsidies has been fully realized, and it has become an important force in my country's energy structure transformation." National People's Congress Representative, Sunshine Cao Renxian, chairman of the power supply, said.
Zhang Tianren believes that accelerating the construction and integration of wind power and photovoltaic power generation projects and increasing the supply of clean power will not only help ease the tension between power supply and demand, but also help achieve the goal of dual control of energy consumption and promote low-carbon energy transformation.
Problems such as electricity price and consumption still need to be solved
However, there are also shortcomings in the rapid development.
"At a time when the electricity consumption of the whole society in my country is increasing steadily and the new energy power generation has reached a new high, there are still problems that are not conducive to the sustainable and healthy development of the industry." Zhang Tianren believes that the new energy power generation industry needs to be further regulated, and its healthy and sustainable development should be promoted. sequential development.
Cao Renxian pays special attention to the issue of new energy on-grid electricity prices.
He analyzed that since the second half of 2020, the prices of materials and equipment related to the photovoltaic industry chain such as polysilicon have risen. In addition, photovoltaic power plants need to be equipped with a certain proportion of energy storage systems as required, and investment has increased. Overall, the power generation cost of photovoltaic power plants has increased by 20%— 25%.
"Because the on-grid electricity price is based on the benchmark price of coal in various places and is relatively low, the return on investment of photovoltaic power plants has fallen sharply or even lost money." Cao Renxian said.
Zhang Tianren mentioned that some areas have insufficient capacity to absorb new energy power. For example, the "Three Norths" areas with concentrated wind power installed capacity are far away from the load center, so it is difficult to consume on-site, and the development of the power grid is lagging behind.
In addition, the development goals of new energy power are frequently adjusted, and special plans at all levels cannot be effectively connected. There have been problems such as disconnection between local planning and national planning, and disconnection between new energy power generation and power grid planning.
He also mentioned that the vicious competition in the new energy power generation industry has intensified. The current project development method often allocates new energy resources to entities who have no desire to hold operating projects for a long time, and even breeds a group of middlemen who specialize in resource transfer information introduction. .
It is recommended to take multiple measures to solve the problems of industrial development
How to promote the healthy development of the new energy power generation industry, the representatives gave their suggestions.
In terms of new energy on-grid electricity prices, Cao Renxian suggested that the guaranteed purchase price of new projects should be determined based on the kWh cost of photovoltaic power plants in various regions plus reasonable income, and the price should be calculated once a year.
He also suggested that the green power trading market should be accelerated to mature, and a mandatory green power trading market with quota system should be established in a timely manner to release the development potential of both green power suppliers and demanders; and a price mechanism for the energy storage system of photovoltaic power plants should be established as soon as possible.
"It is recommended to issue a special plan for energy storage as soon as possible to promote the implementation of support policies for the allocation of energy storage facilities for new energy projects... to ensure that new energy can be delivered, supplied and used well." Zhang Tianren said.
In addition, he proposed that the interconnection of provincial power grids in the region should be strengthened to effectively alleviate the peak load regulation pressure in some regions; the mode of national financial subsidy support should be adjusted to promote reasonable pricing of products and avoid vicious competition.
It is worth noting that Zhang Tianren also mentioned the concept of "new energy +".
He suggested to combine agriculture, sand control, fishery, tourism, etc. with new energy power generation applications, improve land use efficiency, and realize a comprehensive development model that can generate electricity at the top and control desertification at the bottom, planting, fish farming, and combination with ecotourism. .
