On July 4, 2022, the Xinjiang Uygur Autonomous Region Development and Reform Commission issued a notice on issues related to printing and distributing the second batch of market-oriented grid-connected new energy projects in the autonomous region in 2022. A total of 67 projects were included in the list. Among them, two new energy projects including the Hami solar thermal storage and multi-energy complementary integration green power demonstration project invested and constructed by China Energy Construction were selected.

According to the list, the total installed capacity of 67 projects is 47,832,500 kilowatts, of which 27,390,000 kilowatts are photovoltaic projects, 13,495,000 kilowatts of wind power projects, and 6,947,500 kilowatts of storage capacity. The distribution and storage types include solar thermal and electrochemistry. Among them, there are 13 solar thermal power generation projects with a total of 1.35 million kilowatts, accounting for 19.43% of the distribution and storage scale.

The China Energy Construction Hami solar-thermal storage and multi-energy complementary integrated green power demonstration project invested and constructed by China Energy Construction Investment Corporation ranks first in the project list. The total designed installed capacity of the base is 1.5 million kilowatts, including 1.35 million kilowatts of photovoltaic and 150,000 kilowatts of solar thermal. . According to the notice, the projects included in the list are deemed to be on record, which marks the official landing of the world's largest solar thermal storage demonstration base project in Xinjiang.

Solar thermal base site

The solar thermal base is located in Hami City, an important area for Xinjiang power delivery. The local atmosphere has good transparency, less cloud cover, and abundant light resources. The annual sunshine hours are 3,300 to 3,500 hours, which is one of the areas with the most sunshine hours in the country. It is very beneficial to solar thermal power generation.

Hami Solar Thermal Project

The solar thermal base will continue the peak shaving function of the power grid system and adopt a thermal storage type solar thermal construction scheme. The solar thermal power station adjusts the output at different time periods by starting and stopping peak shaving and output reduction, so as to smooth the photovoltaic output curve. At the same time, the electric heating device can further exert the adjustment characteristics of the solar thermal power station, receive the amount of abandoned wind and photovoltaic power from the grid system, and then generate electricity and use it when the load peaks, so as to improve the peak capacity of new energy.

Effect drawing of control center of solar thermal base

The solar thermal base will also build a comprehensive energy base regulation center that is clean-led, multi-energy complementary, domestically leading, and world-class by building a comprehensive energy Internet and an integrated solar-thermal storage regulation center. The project construction is an innovative demonstration of the market-oriented grid-connection model beyond the guaranteed grid-connection scale, which is conducive to the construction of a new power system with new energy as the main body, and is conducive to increasing the proportion of non-water renewable energy power consumption in Xinjiang Autonomous Region and promoting new energy. The sustainable and healthy development of the industry has important practical significance. Editor/Zhao E
