100 Climate Actions from Cities in Asia and the Pacific


Delingha’s new Concentrated Solar Power (CSP) project is providing a boost of 50 megawatts (MW) of clean energy to the power grid and reducing CO2 equivalent emissions by an estimated 195,000 tons every year.

The 50 MW CSP plant in the city of Delingha, Qinghai Province, is the first of its kind in the PRC and came into operation in May 2020. The plant works using parabolically shaped panels that concentrate sunlight to heat water to steam, which in turn drives a turbine to create power. The thermal element of the design allows the plant to be combined with energy storage facilities, thus providing greater flexibility compared with traditional wind or solar energy. The plant will reduce an estimated 195,000 tons of CO2 per year.



As well as constructing the first-of-its-kind utility-scale CSP plant in Qinghai Province, the project also includes capacity development and training in CSP design, construction, and operation and management.

The project was made possible through an ADB-loan of $150 million and $96.68 million in counterpart financing from the China General Nuclear Power Corporation (CGN).

The Challenge

Delingha has an abundance of solar resources that can propel the growth of a solar-based industry, but the city is constrained with limited financial resources and hands-on technology experience.


Economic Employment opportunities will help to diversify and boost the local economy.

Social This project is contributing to diversifying the local economic base as well as creating 334 unskilled jobs annually during construction and 30 permanent jobs during operation and maintenance.
