In recent years, based on the rich energy advantages, the Qinghai Provincial Government in accordance with the “Qinghai to build an important new energy industry base” important guiding spirit, to create a national clean energy demonstration province as a traction, and steadily promote. Two million kilowatts of Hainan and Haixi new energy base, and built the first large-scale energy storage lights in the country.
The Thermal Power Demonstration Project is the world's largest PV power plant cluster and the largest 850 MW water-photovoltaic power plant in Longyangxia, with an average annual growth of 1 million kilowatts, and an average annual growth rate of 581 TP3 T. The development and utilization of solar energy is at the forefront of the country. Based on the strong peak shifting capacity of the broad power grid and the upstream Yellow River terraced hydropower plants, in March 2016, Qinghai's surplus PV power was delivered to East China for the first time at 98 million kWh. Through inter-provincial cross-border power trading, in 2017, Qinghai added a cumulative total of 2 billion kWh of new energy and energy sources, realizing new energy consumption in the provincial market.
As the first ultra-high voltage DC transmission project in Qinghai, Hainan + 800,000 volts DC transmission project will start construction within the year and is expected to be put into operation in 2020. After the project is completed and put into operation, it will mainly transport new energy and is expected to generate 52.3 billion kilowatt-hours of electricity annually and reduce coal burning by more than 2,200 tons. It will effectively promote new energy in Qinghai and the entire Northwest China, realizing a wider range of water and fire mutual aid, wind and light complementation, and promoting the green transformation and upgrading of energy. With the expansion of the scale of the market outside the province, the advantages of large-scale and long-distance transmission of clean electricity from the extra-high voltage grid are becoming more and more prominent.
From 0 hours on June 17, 2017 to 24 hours on June 23, 2017, Qinghai had seven consecutive hours of all-clean power supply. During this period, a total of 1.18 billion kWh of electricity was used, resulting in “zero-emission” electricity. Since May 2016, the Portuguese National Grid has surpassed the Portuguese National Grid in terms of duration, operational difficulty and power supply structure for 4 days and 107 hours of clean energy supply. This is the first time in China, and it is of great significance to promote China's energy transformation, and to promote the sustainable, efficient and healthy development and efficient utilization of clean energy.” The general manager of Qinghai Electric Power Company said.
Following Green Harmony 2017, Qinghai realized seven days of completely clean energy supply. After the groundbreaking step of saying goodbye to fossil energy, Qinghai will once again run 216 hours of green power for nine days to achieve “zero emissions” in the province.
Qinghai's clean energy is widely distributed, with strong spatial and temporal complementarity. There is complementarity between light and light, wind and wind, wind and light, wind, light and water, which can smooth the rise and fall of new energy sources. At the same time, by utilizing the fast regulation ability of hydropower and the energy storage of light and heat, the power generation quality of new energy can be greatly improved, so as to achieve clean power. Excess ratio.
Based on the strong peak shifting capacity of the broad power grid and the upper Yellow River terrace hydropower stations, in March 2016, Qinghai's surplus PV power was delivered to East China for the first time at 98 million kilowatt-hours (kWh). Through inter-provincial cross-border power trading, in 2017, Qinghai added a total of 2 billion kWh of new energy and energy sources to realize new energy consumption in the provincial market. With the expansion of the scale of the extra-provincial market, the advantages of large-scale and long-distance transmission of clean electricity from the extra-high voltage grid are increasingly prominent.
