  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...

  According to CCTV News, on January 7, the largest tidal flat photovoltaic storage power station in the country and the largest single-unit photovoltaic project in operation in Shandong Province, the Huadian Shandong Laizhou Large-scale Salt-alkali Tidal Flat Photovoltaic Storage Integrated Project, was connected to the grid for power generation. The entire project covers an area of ​​18,000 mu, with a total of nearly 2 million photovoltaic panels laid. After all are put into production, it will not only provide a steady stream of clean electricity, but also inject brine under the photovoltaic panels to increase salt production and income for local people. The Huadian Laizhou Large-scale Salt-alkali Tidal Flat Photovoltaic Storage Integrated Project is one of the third batch of large-scale wind power photovoltaic bases in the country, with an installed capacity of 1,000 megawatts and supporting construction of a 200 megawatt/400 megawatt-hour electrochemical energy storage project. The power station integrates "photovoltaic power generation + salt production" and realizes a composite industrial model. It is reported that after the project is put into production, it can generate 1.442 billion kilowatt-hours of electricity per year, which can meet the annual electricity consumption of about 500,000 households. 444,000 tons of standard coal are saved annually. The salt-light complementary mode is adopted. The solar panels all use double-sided double-glass technology. Under the irradiation of sunlight, the brine reflects light to the back of the module, which can increase the power generation efficiency by about 3%. At the same time, the photovoltaic modules have a thermal effect, which can increase the temperature of the salt pool by about 2°C, increase the concentration of brine, and increase the salt production, thus achieving a complementary and win-win situation between salt production and photovoltaic power generation. The project also built a supporting energy storage system power station. The white boxes in the picture above are like huge power banks. When the sun is strong during the day, the excess solar energy is stored here, and the stored electricity is released at night, becoming a photovoltaic power station that can generate electricity at night. At the same time, due to the use of new electrochemical energy storage technology, it not only has the function of a power bank, but also can play a role in voltage stabilization and frequency regulation when the power grid fluctuates, ensuring the safety and stability of the power grid. Tidal flat photovoltaic energy storage power stations usually refer to photovoltaic energy storage projects built in complex areas such as sandy and silty areas along the coast of oceans and rivers with excellent sunshine conditions. Taking the Huadian Laizhou saline-alkali tidal flat photovoltaic storage integrated project as an example, the annual average sunshine time here is more than 2,600 hours...
