The Brief
More than 800 industry representatives met in Xining, Qinghai province, for the 20th China Solar Thermal Electricity Conference to discuss strategies for scaling concentrated solar power (CSP). Convening from August 12 to 14, the conference aligned technical and industrial priorities with China's upcoming 15th Five-Year Plan targets and a broader national objective of reaching 15 gigawatts (15 million kilowatts) of installed solar thermal capacity by 2030. Key discussions centered on advancing core technologies, lowering construction costs, and commercializing integrated solar thermal and storage systems.
Why it matters
Solar thermal power uniquely integrates electricity generation with built-in thermal storage, providing critical peaking support and grid stability for renewable-heavy energy systems. With China targeting 15 gigawatts of solar thermal capacity by 2030, industry progress on cost reduction and technical scalability will determine how effectively the technology can support the broader integration of intermittent wind and solar power.
China context
Under China's dual carbon targets and the ongoing construction of a new power system, northwestern provinces like Qinghai serve as primary bases for clean energy generation and transmission. The regional development strategy is progressively shifting from standalone photovoltaic and wind installations toward full-chain 'solar thermal plus storage' systems to alleviate grid congestion and manage dispatch challenges.
Editor's View
EDITOR'S VIEW — Analysis and inference, not factual reporting.
While concentrated solar power provides continuous, dispatchable renewable energy that conventional solar PV cannot easily match without massive battery installations, its primary barrier remains the high capital expenditure and levelized cost of electricity. The target of 15 gigawatts by 2030 signals serious policy intent, yet achieving this benchmark will rely heavily on whether the domestic supply chain can replicate the rapid cost deflation previously seen in China's photovoltaic and wind manufacturing sectors.
What to watch
- Specific solar thermal installation quotas and support mechanisms outlined in the upcoming 15th Five-Year Plan
- Technological breakthroughs in domestic CSP equipment and subsequent changes in levelized cost of electricity (LCOE)

More than 800 industry representatives gathered in Xining, the capital of northwestern China's Qinghai province, to map out the commercialization pathway for concentrated solar power (CSP) and energy storage systems, according to a report by China News Service.
The 20th China Solar Thermal Electricity Conference, held from August 12 to 14, focused on technological innovation as a primary driver for deploying solar thermal projects at scale. Delegates aligned discussions with the development goals of China's upcoming 15th Five-Year Plan, specifically addressing the national development target of reaching 15 gigawatts (15 million kilowatts) of installed solar thermal capacity by 2030.
Discussions throughout the three-day event centered on overcoming technological bottlenecks, reducing project construction costs, and establishing a full industrial supply chain. Concentrated solar power, which uses mirrors to focus sunlight and heat a transfer fluid to drive conventional steam turbines, incorporates thermal energy storage that allows plants to generate electricity reliably even when the sun is not shining.
Qinghai and other northwestern regions in China have become central testing grounds for integrated renewable energy complexes. These hybrid projects combine solar photovoltaics, wind power, and solar thermal generation, using thermal storage systems to balance grid fluctuations and provide stable baseload and peak-shaving power for long-distance transmission lines.
