China's 1,100 kilovolt ultra-high voltage direct current (UHVDC) power transmission project, a major line that stretches from Xinjiang Uygur Autonomous Region to Anhui Province, has delivered over 300 billion kWh of electricity from west to east as of Sunday since it began operation in September 2019.

The project, which starts in Changji Hui Autonomous Prefecture of northwest China's Xinjiang Uygur Autonomous Region and ends in Xuancheng City in southern Anhui Province, has supplied a total of 300.001 billion kWh of electricity as of 05:00, sufficing 133 million households in a year, according to the real-time data of the Guquan converter station in Xuancheng. "Since it began operation, the output of this project amounts to saving 90 million tons of standard coal and reducing carbon dioxide emissions by more than 255 million tons for east China, playing an important role in promoting energy transformation and development," said Gui Xuexiang, deputy head of the Guquan converter station's power transformation operation and maintenance office.

The Changji-Guquan UHVDC power line has a length of 3,324 kilometers, passing through the six provinces and regions of Xinjiang, Gansu, Ningxia, Shaanxi, Henan and Anhui. It has the world's highest voltage level, biggest transmission capacity, and longest transmission distance.

The project has sent out rich thermal, wind and solar power in the western region, fully verifying the advantages of China's UHVDC transmission technology in terms of large capacity, long distance and high efficiency.

S Africa declares national disaster as flooding batters northern region

South Africa's National Disaster Management Centre declared a national disaster on Sunday as heavy rains and flooding continued to batter northern parts of the country.

According to local media reports, continuous rainfall since late December has caused severe flooding in Limpopo Province, where at least 17 people, including two children, have died. Minister of Cooperative Governance and Traditional Affairs Velenkosini Hlabisa said in a statement on Sunday that 20 people had been killed in flood-related incidents in Mpumalanga Province.

More than 1,600 homes and 31 schools have been affected in Limpopo, while over 1,000 homes in Mpumalanga have suffered varying degrees of damage. The flooding has also forced the partial closure of Kruger National Park, one of Africa's largest wildlife reserves, with more than 600 visitors evacuated after rising waters inundated access roads and campsites.

The South African National Defence Force has deployed two helicopters to assist with rescue operations and evacuate residents stranded in hard-hit areas.
