Renewable energy construction to speed up green development to add impetus

Only innovation can be self-strengthening, in order to compete. At present, the focus of the global new energy industry has further shifted to China, and China's production of photovoltaic modules, wind turbines, gear boxes and other key components account for 70% of the global market share; The conversion efficiency of silicon heterojunction cells independently developed by Longi Green Energy, a photovoltaic enterprise, reached 26.81%, setting a world record; In 2022, equipment made in China will contribute more than 40% of the global carbon dioxide emission reduction from renewable energy.

The layout of development has been continuously improved, and new models and business forms have emerged

The sun shines on the south Taihang Mountains, and the blue photovoltaic curtain wall extends like a wave. Henan Huixian City Peizhai industrial Park, plant construction is in full swing. "After the plant is installed with photovoltaic curtain wall, it can generate about 330,000 KWH per year, saving electricity cost about 300,000 yuan, and the remaining electricity can bring additional income, which has attracted many enterprises to sign up." Huixian City Zhangcun township Party secretary Guo Dongwei introduced.

Make full use of mountain terrain, farmer roofs, factory buildings and other resources to promote distributed photovoltaic construction. It is expected that by the first half of this year, the number of household photovoltaic installations in Huixian City will exceed 20,000 households, and 150 industrial and commercial photovoltaic power plants.

Centralized and distributed development is carried out simultaneously, and the layout of renewable energy development is optimized.

"Big and strong", the construction of large-scale wind power photovoltaic bases focusing on deserts, Gobi and desert areas is progressing smoothly. As of April this year, the first batch of 97.05 million kilowatts of base projects have been fully started, the project grid work actively promoted, and strive to be completed and put into operation by the end of this year, the second batch of base projects have started construction, and the third batch of base projects have been issued and implemented.

"Small and beautiful", distributed development has become the main way of wind power photovoltaic development. On the roof of the building, the courtyard and the field, the fan whirls and the photovoltaic panel shines. In the first quarter of this year, 33.66 million kilowatts of new grid-connected photovoltaic installations were added, of which 18.13 million kilowatts of distributed photovoltaic power generation, accounting for more than 53%.

The relevant person in charge of the National Energy Administration said that at present, China is focusing on the desert, Gobi and desert areas, accelerating the construction of seven new energy bases on land such as the upper reaches of the Yellow River, Hexi Corridor and Yellow River. Promote the development and construction of the two major water-scenery comprehensive bases in Sichuan, Yunnan, Guizhou, Guangxi and Southeast Tibet; We will promote large-scale offshore development of offshore wind power and far-reaching offshore demonstration development.

New models and new business forms are emerging, and renewable energy application scenarios are integrated and innovative.

The construction site of the Three Gorges new generation grid friendly green power station demonstration project is in full swing in Ulanqab, Inner Mongolia. Under the photovoltaic panel, cold and drought tolerant plants such as alfalfa and Chinese leymus are planted, and the green development model of "power generation on the board and planting under the board" is taking shape.

"Photovoltaic panels can reduce surface water evaporation and increase vegetation growth rate. The first phase of the project will be completed and put into operation by the end of 2021, and the second and third phases are scheduled to be completed by the end of this year." Three Gorges energy construction management branch north construction management deputy director Zhang Xiaolong said.

In Qinghai, through the integration of "ecological photovoltaic + energy storage + heat storage", the State Power Investment has met the power supply and heating needs of more than 30,000 farmers and herdsmen in Guinan County. In Xinjiang, the SINOPEC Kuqa Green Hydrogen demonstration project has entered the sprint stage of production, and the annual output of green hydrogen can reach 20,000 tons using the advantages of local abundant solar energy resources. New models and new forms of business, such as photovoltaic + agriculture, photovoltaic desertification control, and hydrogen production from renewable energy sources, have formed a new situation of multi-energy complementarities, local conditions, and diversified integrated development.

The construction of power transmission channels has been accelerated, and the level of consumption has been effectively improved

Most of our country's scenic resources are distributed in the "three north" area, while the electricity load is mainly concentrated in the central and eastern and southern regions, and the cross-provincial transmission pressure is large; Coupled with the intermittent volatility of wind power and photovoltaic power generation, large-scale and high proportion access in the future will bring challenges to the smooth operation of the power system. Therefore, renewable energy must be developed on a large scale, but also a high level of consumption.
