The Caipeng Photovoltaic Power Station in Shannan Prefecture of Xizang Autonomous Region has launched operations for its second phase, becoming the world’s highest-altitude photovoltaic station. 

This project surpasses the first phase’s record altitude of 5,100 meters after Reaching elevations between 5,046 and 5,228 meters.

The station covers 134 hectares and now has a total installed capacity of 150 MW. It is expected to generate 246 million kWh of electricity annually, sufficient to power over 50,000 households. 

The project will save approximately 46,800 tons of coal and cut 129,400 tons of carbon dioxide emissions each year, contributing to China’s carbon reduction goals.

The first phase of the station, operational since late 2023, has already produced 40 million kWh of electricity. It reduced seasonal power shortages in Shannan Prefecture and critically stabilized the regional power supply.

The second phase has advanced bifacial photovoltaic panels, which can generate power from both sides by absorbing reflected light from snow and the ground improving efficiency by 20%.

It is designed to encounter extreme conditions, including temperatures as low as -40°C, high winds, and heavy snow, these panels are built to last over 25 years.

The project incorporates innovative grid-forming energy storage technology which addresses renewable energy’s intermittency by storing solar power during the day and delivering it at night. This will ensure a stable and reliable electricity supply to the Xizang grid.

With solar power now accounting for 24.8% of China’s total installed electricity capacity, the Caipeng Photovoltaic Power Station demonstrates the country’s commitment to renewable energy and its efforts to develop sustainable infrastructure in even the most challenging environments.
