China has begun construction on an ultra-high voltage direct current (UHVDC) power line stretching 2,681 kilometers from the Xizang Autonomous Region in the west to the Guangdong-Hong Kong-Macao Greater Bay Area in the east. With a total investment of USD7.5 billion (CNY53.2 billion), the project is expected to be the world's largest clean electricity transmission line once completed in 2029.

The line will carry up to 10 million kilowatts of power and supply over 43 billion kilowatt-hours of clean electricity annually to the Greater Bay Area--equivalent to half the output of the Three Gorges Dam. Operators State Grid Corporation of China and China Southern Power Grid estimate this will reduce coal consumption by 12 million tons and cut greenhouse gas emissions by 33 million tons per year.

The project is expected to stimulate development of new power equipment, attract over USD14.1 billion (CNY100 billion)  in industrial investment, and create more than 100,000 jobs.

The initiative continues China's West-to-East Power Transmission Project, which began in the 1990s to transfer abundant energy from the resource-rich west to industrialized eastern regions. Xizang, sitting on the world's highest plateau, generates over 99% of its electricity from clean sources, while Guangdong remains China's largest power consumer.

By 2050, Xizang plans more than 10 transmission corridors exporting over 500 billion kilowatt-hours annually, reinforcing China's strategy to maximize renewable energy usage and support clean energy supply across the nation.
