China’s first million-kilowatt level offshore photovoltaic project was successfully connected to the national power grid, according to China Energy on Wednesday.
Located in the offshore area eight kilometers from Dongying City of Shandong Province, the one-million-kilowatt offshore photovoltaic project has seen the completion of the first 300 photovoltaic platforms, arranged in five rows extending towards the deep sea. Each platform measures 60 meters in length and 35 meters in width, equivalent to the size of five standard basketball courts. The entire project will require the installation of 2,934 such photovoltaic platforms.
This project is currently the largest open-sea offshore photovoltaic project in China, covering an area of approximately 1,223 hectares. It is the first project to apply 66-kilovolt undersea cables and long-distance land cables to offer greater transmission capacity at lower costs.
"Once fully connected to the grid, the annual power generation is estimated to reach 1.78 billion kilowatt-hours, roughly meeting the annual electricity consumption of 2.67 million urban residents in China, saving approximately 503,800 tons of standard coal and reducing carbon dioxide emissions by 1.347 million tons," said Wang Lin, project manager of Shandong Kenli Project.
In contrast to traditional land-based photovoltaic farms where solar panels are typically assembled on-site, offshore photovoltaic farms require a unique approach. The initial assembly phase for offshore installations begins on land. Here, workers meticulously assemble both the solar panels and their supporting structures before transporting the entire unit to the site using tugboats. Once on location, the solar panels are then carefully lifted and mounted onto four pre-installed steel piles, ensuring the stability and functionality of the offshore photovoltaic array.
While only two meters of the steel piles are above the water surface, approximately 23 meters are submerged below, with 17 meters anchored into the seabed. The piles are coated with a special anti-corrosion primer, ensuring a lifespan of over 30 years. Moreover, the platform can withstand strong winds and sea ice as thick as 25 centimeters.
All the photovoltaic panels in this project face south, with a precisely calibrated tilt angle of 15 degrees. This angle maximizes the panels' exposure to sunlight. These double-sided panels not only capture direct sunlight from above but also utilize light reflected from the sea surface. This design enhances the power generation of each panel by around three percent.

Athletes from various ethnic groups across China competed in both traditional sports, such as crossbow shooting and dragon boat racing, and new additions like the debut of coconut tree climbing race on the first official competition day of China's 12th National Traditional Games of Ethnic Minorities.
Opening in Sanya, a coastal city of Hainan Province, on Friday, the grand event gathers nearly 7,000 athletes representing 35 delegations across China who will compete in 18 sports and three demonstration sports. The nine-day event will conclude on November 30.
Competitors at the event are expected to not only showcase their skills and traditional culture, but also enjoy the fun of sports.
Inspired by local people's physical labor of climbing trees to harvest coconuts in Hainan, the coconut tree climbing race made its first appearance this year.
Twelve teams from provinces including Hainan and north China's Hebei participated.
"I feel so excited. I like the sport item very much. It gives us a chance to see the unique customs of different ethnic groups. It's a wonderful chance for us to have such exchanges. I'm so happy to be here," said a spectator from northeast China's Heilongjiang Province.
The board-shoe racing, a popular traditional sport, pits teams of three athletes wearing a single pair of wooden board shoes against each other. Originating from southwestern regions including China's Guangxi Zhuang Autonomous Region, the event has grown in popularity, attracting participants from northern provinces as well.
"The board-shoe racing exemplifies the sports wisdom and collaborative spirit of ethnic minorities. There are 30 teams participating in the event. The registration shows that it is increasingly popular among people of all ethnic groups. Provinces in the northern part are also actively participating in this event. It witnesses the multicultural integration and exchange among Chinese ethnic groups," said Lu Guang, leader of board-shoe racing team from Shandong.
From land-based sports like crossbow shooting and wrestling to water events such as dragon boat racing, the first day of the games featured 15 competitions. Players can not only learn from each other by competing in the field, but also forge new friendship.
"We will show our best and show Yunnan's colorful national sports culture and hard-working and simple spirit," said Li Jixin, coach of dragon boat racing team from Yunnan.
"They are rivals on the field and friends off the field. Athletes' mutual communication and discussion are also conducive to strengthening exchanges between cultures of different ethnic groups," said Guan Yuanhong, leader of the crossbow shooting team from Jiangxi.
