(Economic Observation) How does China's clean energy "enrichment zone" not mistake "scenery"?
China News Agency, Urumqi, May 30 (Zhou Guangke) In the Junggar Basin, China's second largest inland basin, the construction site of the 750 kV Altay-Zhunbei line project section I was roaring mechanically. The project is expected to be completed in late August this year. By then, Xinjiang will extend the main grid of the 750 kV power grid to the northernmost region, thereby promoting the development of local clean energy.
Xinjiang is located in northwestern China. It is rich in wind and solar resources and is an ideal place for the development of clean energy industry. According to data from State Grid Xinjiang Electric Power Co., Ltd., the total installed capacity in Xinjiang's power grid exceeds 92 million kilowatts, of which clean energy power generation exceeds 36 million kilowatts, accounting for more than 40% of the total installed capacity.
As more and more "wind and light" resources are converted into electrical energy, there is a trend of "supply exceeds demand" for clean energy. The power grid is a pivotal platform for energy conversion, utilization and optimal configuration, and it has also become the key to solving problems. Since the "Thirteenth Five-Year Plan", Xinjiang has gradually formed the main grid structure of the "four-loop power supply network in Xinjiang and four channels for Xinjiang power delivery".
The data shows that, relying on 4 "Xiangdian Power Delivery" channels, in the first quarter of this year, Xinjiang New Energy's "Xinjiang Power Delivery" reached 4.2 billion kWh, accounting for about 20% of the "Xinjiang Power Delivery" electricity. This move not only eases energy consumption in Xinjiang, but also promotes energy conservation and emission reduction in the central and eastern provinces.
In terms of "power supply in Xinjiang", in 2019, Xinjiang's Xinjiang power users marketed more than 46.2 billion kWh of electricity, and the dividends generated through the transaction exceeded 4 billion yuan. Data show that on April 15 this year, the total output of new energy of Xinjiang Power Grid hit a record high, reaching 15.47 million kilowatts, and the output of new energy power generation accounted for more than 54% of the entire network power load at that time.
"New energy + energy storage" is a recognized and important solution to the problem of consumption in the rapid development of clean energy. According to the State Grid Xinjiang Electric Power Co., Ltd., in May of this year, the company completed the 35-kV energy-saving Keping Energy Storage Station No. 1 power grid test, which was the first successful attempt of Xinjiang in the energy storage power plant grid test.
In May this year, the Xinjiang Uygur Autonomous Region Development and Reform Commission issued the "Notice on Doing a Good Job in the Construction of Wind Power and Photovoltaic Power Generation Projects in 2020." The document proposes to continue to promote the construction of pilot projects on photovoltaic side energy storage such as photovoltaic energy storage in southern Xinjiang and centralized energy storage in new energy collection stations; focus on promoting the construction of pumped storage power stations such as Fukang and Hami, and strive for 2023 and 2026 respectively Completed and put into operation.
At the same time, Xinjiang has carried out pilot construction of new energy sources by improving the digital management level and resource allocation capabilities of the power grid. At present, State Grid Xinjiang Electric Power Co., Ltd. has completed the demand analysis and system construction of 15 platforms including grid services, consumption calculation, and technical consulting. The later construction will provide strong technical support for the development of clean energy in Xinjiang.
According to data released by the Development and Reform Commission of the Xinjiang Uygur Autonomous Region, from January to April this year, wind curtailment in Xinjiang continued to decline, and wind power operation was stable; the amount of photovoltaic curtailment and the rate of curtailment decreased slightly from the same period last year. According to estimates, this year ’s clean energy generation in Xinjiang will reach 60 billion kWh. (Finish)
