China Mobile Leverages "Green Roof of the World" for Base Station Power

China Mobile has now completed its "Green Roof of the World' , a project begun in 2004 to install solar and wind power generating facilities in at least 1,000 sites on the Qinghai-Tibet Plateau at an average height of 4,000 meters above sea level. Huawei has been a lead supplier for the project, which has included installations on Mount Everest.

By the end of 2008, no less than 683 villages and towns (over 70 % of the total) had wireless connectivity, enabling access to the Internet. By the end of June 2009, 1,156 solar power sites had been built on the Qinghai-Tibet Plateau, forming the world's largest solar power site group. Nearly 80% of the 1,000 BTS sites in this area are using solar power now.

The installed solar power capacity of China Mobile in the Qinghai-Tibet Plateau now totals 10,000 kilowatts, with an annual generation capacity of approximately 20 million kWh.

China Mobile now plans to deploy an additional 1,000 solar power sites. In addition China Mobile is researching wind/solar + mains hybrid power supply systems. It is also piloting new sources of power such as fuel cells, small hydro power, and terrestrial heat.
