The water in the river, the wind in the mountains, the endless sunshine... As a major province of clean energy resources, sichuan province's "Decision on Promoting the High-quality Development of Green and Low-carbon Advantageous Industries under the Leadership of Achieving carbon peak carbon neutrality goals" clearly put forward "promoting the integrated development of water, wind and solar multi-energy complementary development", "scientific and orderly development of hydropower", "accelerating the development of wind and solar power generation" and "achieving carbon peak carbon neutrality target strategic support area", which clarified the goals and pointed out the direction for Sichuan's new energy development.
"Green and low-carbon" and "clean energy" are the "hot words" of the two sessions of Sichuan Province this year, in the context of carbon peaking and carbon neutrality, how will Sichuan Province contribute to the realization of the "3060" goal?
Yang Enguo, a deputy to the Sichuan Provincial People's Congress
Yang Enguo, deputy to the Sichuan Provincial People's Congress and member of the Expert Committee of Yalong River Basin Hydropower Development Co., Ltd., suggested that the development of the four major water-wind and solar complementary renewable clean energy bases in the middle reaches of the Jinsha River, the upper reaches of the Jinsha River, the Yalong River and the Dadu River should be studied as soon as possible, the relevant development policies should be clarified, the experience of sichuan new energy development should be explored and accumulated, and the construction of the four major bases should lead the healthy and orderly sustainable development of new energy in Sichuan Province.
The total amount of renewable clean energy resources is the first in the country
By 2025, the installed capacity of clean energy will reach 130 million kW
According to the "Opinions on The Complete, Accurate and Comprehensive Implementation of the New Development Concept to Do a Good Job in Carbon Peaking and Carbon Neutrality" issued by the CPC Central Committee and the State Council, focusing on the overall goal of national "3060" carbon peaking and carbon neutrality, in recent years, a number of policies have been successively introduced to accelerate the development of new energy in the mainland, which focuses on supporting the development of wind and photovoltaic renewable clean energy and the construction of smart grids.
As a major province of clean energy resources, Sichuan Province has the first total renewable clean energy resources in the country, of which hydropower resources are about 148 million kW, mainly concentrated in the Dadu River, Yalong River and Jinsha River basins, and have been completed and put into operation 89.47 million kW. New energy resources are also extremely rich, with more than 100 million kW of developable wind and solar power generation resources, of which the water and wind power generation can be developed in the water and wind complementary clean energy bases planned for hydropower projects in the Dadu River, Yalong River and Jinsha River basins, and the developable resources for wind and solar power generation exceed 80 million kW。

The Provincial Party Committee and the Provincial Government actively responded to the call of the central government, and the Tenth Plenary Session of the Eleventh Plenary Session of the Sichuan Provincial Party Committee adopted the "Decision on Promoting the High-quality Development of Green and Low-Carbon Advantageous Industries under the Leadership of Achieving the Carbon Peak Carbon Neutrality Goal", which clearly put forward "promoting the integrated development of water, wind and photovoltaic multi-energy complementary development", "scientific and orderly development of hydropower", "accelerating the development of wind and solar power generation", "achieving carbon peak carbon neutrality target strategic support area", by 2025, Sichuan Province's installed clean energy capacity will reach 130 million kW, by 2025, In 2030 and 2035, the proportion of clean energy consumption in Sichuan Province will reach 60%, 66%, and 70% respectively, and it will make greater contributions to the establishment of a green, low-carbon circular development economic system and a clean, low-carbon, safe and efficient energy system in the country, and steadily move towards achieving the goal of carbon neutrality.
Renewable clean energy has great potential for development
The development of clean energy has put forward higher requirements for the structure of the power grid
"Although the total amount of renewable clean energy resources is the first in the country, the development of renewable clean energy in Sichuan Province lags behind the national average." Yang Enguo said that by the end of 2020, the total installed capacity of Sichuan's power system will reach 102.95 million kW, of which the installed capacity of new energy is only 6.17 million kW (530 million kW in the country), the annual power generation capacity is 11.3 billion kWh (the national is 727.6 billion kWh), accounting for only 6% and 2.72% of the province's power system, respectively, which is lower than the 24.1% and 9.54% of the national power system level.
According to the 14th Five-Year Development Plan of Sichuan Province, by the end of 2025, Sichuan's new installed capacity of wind and photovoltaics will be 10 million kW, which is only about 1.7% of the same period in the country; by 2030, Sichuan's new energy power generation will account for 19.2%, far below the national target of 30% of new energy power generation, "which is extremely incompatible with Sichuan's new energy resources province." ”

At the same time, Yang Enguo also believes that since the reform of the power system, the power supply construction in Sichuan's power system has developed rapidly, and the largest provincial power grid platform and the largest sending terminal platform in the country have been built, which has made outstanding contributions to the "west-to-east power transmission", but due to the system and mechanism problems, the construction of the Sichuan power grid still lags behind the progress of power supply construction, regardless of the transmission channel and the backbone power grid in the province, there are generally problems such as the construction progress lags behind the power supply construction, the transmission capacity of the high-voltage main network is low, and the upgrading and transformation of the low-voltage distribution network is insufficient.
"The development of new energy has put forward higher requirements for Sichuan's power grid, and the existing power grid structure has affected the existing clean energy benefits in Sichuan, and seriously restricted the development and utilization of wind and solar power generation resources, and the upgrading of the power grid has been very urgent." Yang Enguo said that among the renewable and clean energy that can be developed in Sichuan, both hydropower and wind and photovoltaic resources are mainly distributed in "three states and one city", and the reverse distribution with the electricity load center, the scale of development and the benefits are seriously subject to the transmission and distribution structure and capacity of the power grid.

It is recommended to increase the investment in power grid transformation and upgrading
As soon as possible, the development of the four major water- wind and photovoltaic complementary renewable clean energy bases will be clarified
In terms of making up for the shortcomings of the power grid and coordinating the construction of the power grid, Yang Enguo suggested that the construction of power transmission channels should be accelerated, the intensity of power grid upgrading and capital investment should be increased, and special financial support for power grid transformation and upgrading should be appropriately provided, and at the same time, certain fees should be charged on the sales side and the power supply side, and special funds for power grid upgrading should be established. Technically, as soon as possible, the Sichuan power grid development plan and overall structure will be comprehensively reviewed and optimized, the layout of the relevant regional transmission and distribution network will be comprehensively adjusted, the local consumption capacity of clean energy will be effectively improved, based on the present and long-term, to meet the long-term energy needs of social and economic development in various places, to provide conditions for the large-scale development of wind and photovoltaic resources in the province, to provide renewable clean energy for Sichuan load centers, and to help achieve carbon emission reduction targets。

Yang Enguo also suggested that we strengthen policy guidance, give full play to the power grid regulation role of large and medium-sized hydropower stations, establish and improve the policy of peak regulation and frequency regulation accident standby power supply electricity prices and capacity electricity prices as soon as possible, give priority to increasing the installed capacity of large and medium-sized hydropower stations under construction and in the near future, expand and renovate and increase the capacity of large and medium-sized hydropower stations that have been built with good regulation performance, and strengthen the connection between Sichuan and the northwest power grid, study and implement the feasibility of power supply into Sichuan in Tibet and northwest China, and start the planning and selection of points for pumped storage power stations in the main load area of Sichuan in a timely manner. Increase the reserve of standby regulation power resources to provide strategic reserves for further improving the regulation capacity of the power grid。
Focusing on the construction of the four major water-wind complementary renewable clean energy bases, Yang Enguo suggested that as soon as possible, study and clarify the development of the four major water-wind complementary renewable clean energy bases in the middle reaches of the Jinsha River, the upper reaches of the Jinsha River, the Yalong River, and the Dadu River, establish a special leading group and working group led by the main leaders of the provincial party committee and the provincial government, establish relevant working mechanisms, clarify relevant development policies, coordinate the interests of all parties, innovate the development model, and explore and accumulate sichuan's new energy development experience. And to lead the construction of four major bases to lead the healthy and orderly sustainable development of new energy in Sichuan Province.
