[Wind power system has become the second largest power source in Yunnan]Recently, new energy projects in Yunnan have been put into operation and connected to the grid smoothly. The power generation in Yunnan has reached a new high. At present, the installed wind power system has reached 11.21 million kW, becoming the second largest power source in Yunnan after hydropower. The energy authorities of Yunnan Province will further standardize the competition and distribution of photovoltaic resources in the province, strengthen factor guarantee, and coordinate and promote the synchronous construction of source network projects. We will ensure that 7 million kW will be connected to the grid in the first half of 2023 and 15 million kW will be put into production within the year. Data show that in the first quarter of 2023, the average utilization hours of wind power equipment in Yunnan reached 914 hours, much higher than the national average level of 615 hours. In the first four months of this year, wind power generated 12.427 billion KWH, up 18.78% year on year, becoming the main source of incremental power in Yunnan Province. Yunnan Province has excellent wind energy resources. The wind resources are proportional to the altitude, and the wind speed, the average wind power density and the utilization hours in the upper altitude area all increase. Because most of the mountain Basi areas in Yunnan Province are between 1000m and 2000m above sea level, the high altitude downwind resources have a significant topographic effect, resulting in a higher utilization hours. Data show that the number of hours of wind power utilization in Yunnan ranks the top two in China all year round. Editor/Xu Shengpeng
The fourth phase of Huaneng Yuhuan Power Plant has completed the delivery of the world's first 650 ℃ coal-fired demonstration unit HT700R steam turbine rotor in Shanghai. The rotor adopts domestically produced high-temperature alloy and collaborates with multiple units to tackle the challenges of the entire chain, marking the emergence of new materials from the laboratory and laying a solid foundation for the timely production of core components for this national major scientific and technological research project.

The main structure of the signal complex building for the railway from Yining City to Aksu City in Ili Prefecture, constructed by CR21G, has been topped out, making it the first topped out signal building on the entire line. The project is located near the operating line, with strict construction control measures. After the completion of the railway from Yining City to Aksu City in Ili Prefecture, it will fill the gap in the Tianshan Railway, weave a large railway network in Xinjiang, and reduce logistics costs between the north and south of Xinjiang.
