Tan Hongen, Chairman of State Grid Sichuan Electric Power: Vigorously support large-scale application of new energy storage

China Energy Storage Network News: State Grid Sichuan Electric Power has a deep understanding of the important significance of Sichuan as a province with rich clean energy resources in the national energy security strategic pattern. It insists on being rooted in Sichuan and serving the whole country, striving to be the leader, promoter and pioneer of clean and low-carbon energy transformation, and contributing more to building a new pattern of green and low-carbon energy development and building a new power system.

The significance and characteristics of building a new power system

Building a new power system is of great significance to the transformation and development of the power industry and enterprises.

The new power system is characterized by clean and low-carbon, safe and controllable, flexible and efficient, intelligent and friendly, and open and interactive. From the perspective of the power grid, the new power system presents a pattern in which large power grids are dominant and various power grid forms coexist, and the hub platform role of the power grid is further highlighted; from the perspective of the system as a whole, the operation mechanism and balance mode of the new power system have undergone profound changes, and the power system and other energy systems such as natural gas are increasingly becoming a coordinated and interactive whole.

The power grid connects energy production and consumption, and is a hub platform for energy conversion, utilization, and transmission configuration. As the construction of the new power system is further promoted, the role of the power grid will become more prominent, and it will also face higher requirements. Power grid companies need to jointly overcome a large number of scientific and technological problems at the technical level, establish a multi-dimensional and three-dimensional scientific and technological system under the integration of multiple disciplines, and achieve a high degree of integration of digital technologies represented by "big cloud, things, mobile, intelligence and chain" and advanced physical technologies in the energy field, that is, to achieve horizontal multi-energy complementarity and vertical source, grid, load and storage coordination. At the same time, it is also necessary to accelerate innovation and deepen reform to achieve innovative breakthroughs in management and power market mechanisms.

Take the main responsibility and build a new power system

From a national perspective, Sichuan is an important clean energy base in my country. Sichuan has a technically exploitable hydropower installed capacity of 148 million kilowatts, and a technically exploitable installed capacity of wind power, solar power and other new energy sources of over 100 million kilowatts. In addition, Sichuan's energy development is gradually shifting from "hydropower-oriented" to "hydro, wind and solar power", and its resource endowment advantages are becoming more prominent.

From the perspective of the whole province, energy and electricity are key areas to help achieve the goals of carbon peak and carbon neutrality. As an important part of the "5+1" modern industrial system, the proportion of non-thermal power installed capacity in Sichuan's total installed capacity and the proportion of non-thermal power generation in total power generation are both over 80%. At the same time, Sichuan, which is in the process of new industrialization and urbanization, needs to promote carbon peak and carbon neutrality in a scientific and orderly manner, and provide clean, low-carbon, safe and efficient energy and power guarantees for the province's economic and social development.

From the perspective of the industry, the power grid is a key link in promoting the construction of a new power system. After years of development, the Sichuan power grid has focused on both the synchronization of energy and power supply and economic and social development within the province, as well as the extensive interconnection between Sichuan and other provinces and participation in the national power balance, in the process of building a new power system, promoting the formation of a large power grid as the leading power grid and the coexistence of various power grid forms such as microgrids and distributed energy systems.

From the perspective of enterprises, building a new power system is a favorable opportunity for the transformation and reform of State Grid Sichuan Power. With the large-scale development of new energy and the widespread access to adjustable loads, the traditional power system will change from "source follows load" to "source, grid, load and storage coordinated interaction". State Grid Sichuan Power can make up for the shortcomings of enterprise operation and power grid development while leveraging its first-mover advantage to promote the construction of a new power system, and achieve higher quality, more efficient and more sustainable development.

Accelerate the low-carbon transformation of energy

In recent years, State Grid Sichuan Electric Power has actively explored the low-carbon transformation of energy and electricity, and took the lead in business digitalization and digital industrialization. It has created a batch of "electricity +" products and "electric eye" brands, and its digital development index has reached 67, leading the company's system.

State Grid Sichuan Electric Power has researched and formulated the "Task List for Implementing the Carbon Peak and Carbon Neutrality Action Plan", focusing on "three efforts" to promote carbon peak and carbon neutrality, and strive to build a new power system that conforms to Sichuan's conditions and has Sichuan characteristics.

We will strive to upgrade the power grid to an energy internet and serve the low-carbon transformation of energy. During the 14th Five-Year Plan period, State Grid Sichuan Electric Power will fully promote the construction of 1,000 kV UHV AC projects and increase the construction and transformation of distribution networks. We will strengthen the overall coordination of sources and networks to meet the needs of timely delivery of new energy. We will cooperate with the government to plan distributed power sources and provide one-stop, full-process, high-quality services. We will promote the construction of pumped-storage power stations in accordance with local conditions, vigorously support the large-scale application of new energy storage, create a clean energy configuration platform that complements water, wind and light, and coordinates and interacts with "source, grid, load and storage" to enhance system flexibility.

We will focus on increasing scientific and technological innovation to support the safe, stable and economic operation of the system. We will increase our efforts to tackle key scientific and technological problems in new power systems. We will accelerate digital transformation and build a highly flexible, digital and intelligent power system "brain". We will accelerate the application of new technologies, proactively deploy new energy storage, hydrogen energy and other fields, and explore new technologies for efficient consumption of new energy.

We will focus on deepening the application of green energy on the consumer side, and serve the end-users to reduce emissions and increase efficiency. We will promote the establishment of a sound electricity price formation mechanism, participate in the construction of a unified national electricity market, promote the coordinated development of the electricity market and the carbon trading market, and help establish a clean energy inter-provincial sharing mechanism at the national level. We will strengthen cross-sector integration and electricity substitution, and radiate and drive the development of emerging industries. We will accelerate the construction of the energy big data center, promote government-enterprise cooperation to build the Tianfu New District Park City Carbon Neutral Demonstration Zone, create an "energy smart brain", accurately depict the "carbon footprint", and promote the green and low-carbon transformation of energy consumption.

The 14th Five-Year Plan period is a critical period for achieving the goals of carbon peak and carbon neutrality. State Grid Sichuan Electric Power will unify its thoughts and actions with the spirit of the Sixth Plenary Session of the 19th CPC Central Committee, shoulder the responsibility of being a "major weapon" and "pillar", and accelerate the construction of a new power system around the goals of carbon peak and carbon neutrality, and show new actions and make new contributions in the new era and new journey.
