[Another sea-crossing bridge in Xiamen is about to start construction] On March 22, 2023, the candidates for the survey and design of the cross-East Sea Channel Project in Xiamen have been announced, and the recommended candidates for the bid are Shanghai Municipal Engineering Design and Research Institute Co., Ltd. and Fujian Provincial Transportation Planning and Design Institute Co., Ltd. consortium. The project is located in Jimei District, Tong'an District and Xiang'an District. It starts from Haixiang Avenue, crosses the East China Sea using a public-rail bridge construction scheme, and ends at Xidong Road Airport Expressway, with a total mileage of about 20.9km. The main line of the project adopts the first-class highway and urban expressway, and the auxiliary road adopts the standard of urban trunk road. The main line of the land section has 6 lanes in two directions, the main line of the highway in the sea area has 8 lanes in both directions, and the number of main lines of the track is double; auxiliary roads: Jimei and Tong'an sections have 4 lanes in both directions, and Xiang'an section has 6 lanes in both directions. The design speed of the main line is 80km/h, the design speed of the auxiliary road is 40km/h, and no auxiliary road is set in the sea area. The main line bridge of the land section is 9,938 meters / 4, including 2 super-large bridges: the total length of the Jimei section of the super-large bridge is 2,035.5 meters; the total length of the Xiang'an section of the super-large bridge is 6,838.5 meters. The combined highway and rail bridge in the sea area is about 6.22 kilometers long. The sea-crossing bridge spans two waterways, of which the west navigation hole adopts a cable-stayed bridge with a span of (188+330+188) m; the east navigation hole adopts a steel truss girder with a span of (110+132+110) m. 110m steel truss girders are used for non-navigation holes. The connecting bridge at both ends is 1.82 kilometers long, which is basically the same type as the bridge in the land area. The tentative estimated price of the project is 19.997 billion yuan, of which construction and installation costs are about 13.575 billion yuan. Editor / Zhao E

• [South Africa: Install 18GW of renewable energy generation projects by 2030]
• South Africa is one of the best places in the world to develop photovoltaic projects due to its abundant photovoltaic power resources. The country has set a target of installing 18GW of renewable energy generation facilities by 2030, and photovoltaic systems are expected to make up a large part of that target. The South African Government's Renewable Energy Independent Generator Procurement Program (REIPPP) has been successful in attracting investment and supporting the development of photovoltaic projects in the country. The Renewable Energy Independent Generator Procurement Program (REIPPP) launched its sixth bid window in April 2022. The goal is to add 2,600MW of renewable energy to South Africa's energy mix. Meanwhile, South Africa's national energy regulator NERSA approved the establishment of 15 independent power generators in May 2022 and June 2022. Editor/Xu Shengpeng

• [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
