  On February 20, the Sichuan Anyue 100MW/200MWh new energy storage demonstration project invested and constructed by Sichuan Investment New Energy officially started construction. This project is one of the first batch of new energy storage demonstration projects in Sichuan Province and the first landmark project of Sichuan Investment Group in the field of centralized energy storage. The project is located in Anyue County, Ziyang City, Sichuan Province, with a total investment of approximately 220 million yuan. It is planned to be officially completed and connected to the grid on May 30, 2025. After the project is officially connected to the grid and put into operation, the annual average discharge is expected to be 35,270MWh.

  In the latest ground-mounted PV tender of the German Federal Network Agency, the winning bids hit the lowest record since February 2019.   The winning bids ranged from 0.0388 euros/kWh to 0.0495 euros/kWh, with an average volume-weighted price of 0.0476 euros/kWh, about 6% lower than the average winning bid in the previous round (0.0505 euros/kWh). People's enthusiasm for participation in the German ground-mounted PV tender continued to rise. The tender was oversubscribed by two times, with 524 bids received, totaling 4,708MW. Previous ground-mounted PV tenders also encountered similar oversubscription. In the end, in the tender held on December 1, 2024, the German Federal Network Agency approved a total of 242 bids and signed a total of 2,150MW of PV capacity. "The tendered capacity in this round of ground-mounted photovoltaic tenders was once again significantly higher than the tendered capacity. The continued high level of competition has led to a further decline in the winning bids, which has reduced the public funds available for new projects," said Klaus Müller, President of the Federal Network Agency. In Germany's latest solar project tender, Bavaria ultimately received the most photovoltaic power capacity, with 120 projects totaling 916MW, which is consistent with the results of previous tenders. Schleswig-Holstein followed closely behind, with 231MW of photovoltaic power capacity and a total of 21 projects. Lower Saxony ranked third with 192MW of power capacity and 18 winning projects. Since the adoption of the "Solar Package" last year, this is the first time that the rules for meeting minimum natural environmental protection standards have been implemented in the tender, which aims to improve the compatibility of ground-mounted photovoltaic projects with nature and landscape. On the other hand, in this tender, the measures to increase the maximum capacity of projects to 50MW and the "solar special project" were not applied. The next ground-mounted photovoltaic tender will end on March 1, 2025. Photovoltaic power will take more responsibility for the entire system In other related news, the German government recently adopted several important energy policies. One of the policies stipulates that photovoltaic power will take more responsibility for the entire power generation system. The draft law aims to take measures to address the growing challenge of temporary overgeneration as more renewable power capacity is put into operation. The changes introduced will better integrate power peaks in the grid and strengthen photovoltaic systems while improving network security. The operation of energy storage systems will also be simplified. In addition, the changes are aimed at better handling of negative electricity prices, the controllability of renewable power plants and the controllability of network operators. Robert Habeck, Federal Minister for Economic Affairs and Climate Protection, said: "The decision taken by the Bunde...

  Recently, the 4.2MW photovoltaic project of Beijing-Dezhou Expressway of Xiong'an Jiaotong Company, a subsidiary of Hebei Jiaotong Group, has successfully completed on grid solar system power generation, marking the official operation of the project.   After the project is put into operation, it is expected to generate 5.1436 million kWh of clean electricity per year. According to the coal consumption of thermal power generation, the standard coal consumption per kWh is 300 grams, which is equivalent to saving about 1,543.08 tons of standard coal per year, reducing carbon dioxide emissions by about 5,128.17 tons, sulfur dioxide emissions by about 154.31 tons, and nitrogen oxide emissions by about 77.15 tons. It is of great significance to promote regional energy conservation and emission reduction and help achieve the "dual carbon" goals.   In July 2024, the distributed photovoltaic power generation project of Beijing-Dezhou Expressway issued an EPC general contracting bidding announcement. It is learned from the bidding documents that the project is built in Suqiao Service Area, Longhuzhuang Parking Area, Daliu Town Parking Area, Beijing-Dezhou Expressway Maintenance Center, Huadu Toll Station, Bazhou East Toll Station, as well as service areas, parking areas, and highway slopes.   The project has a total of 15 grid-connected points, all of which are 0.4kV and connected to the low-voltage side of the plant box transformer nearby. The "self-generation and self-use, surplus power to the grid" method is adopted. The energy storage system is configured at 20%/2 hours and adjusted according to the access system plan.   During the project construction, Xiongan Jiaotong Company worked with the professional team of Jijiao Energy to overcome many technical difficulties and construction challenges. From the road safety assessment and design of the project to equipment procurement, construction and grid connection, all parties worked closely together to strictly control the quality and safety of the project and ensure the smooth progress of the project. At the same time, the project follows the concept of green environmental protection, pays attention to the protection of the surrounding ecological environment during the construction process, and achieves a win-win situation of economic and ecological benefits.   The smooth grid connection of the project has added new impetus to the green development of highways in Hebei Province, and also provided a successful example for the integrated development of highways and clean energy. Up to now, the highways under the jurisdiction of Xiongan Jiaotong Company have a total of 36.2 megawatts of grid-connected photovoltaic power, with remarkable results.
