China Energy News: The solar thermal industry is facing new opportunities for development, and experts suggest further improving the electricity pricing mechanism

On March 17th, China Energy Daily published a review article that interviewed industry experts such as Sun Rui, a consultant from the General Electric Power Planning and Design Institute and Vice Chairman of the Solar Photothermal Alliance Expert Committee, Wang Yi, Director of the Standardization Management Center of China Electricity Union, and Jin Jianxiang, Chairman and Chief Engineer of Zhejiang Kesheng Technology Co., Ltd.

The article believes that with the construction of a number of complementary new energy projects for wind, solar, and thermal energy, China's solar and thermal industry has ushered in new development opportunities. However, at present, the power grid company only pays the local benchmark electricity price for coal-fired power generation, which makes it impossible for the power generation cost of solar thermal power projects to be transmitted to the backend, and the investors cannot achieve it, which restricts the development of the solar thermal power generation industry. There is a market, demand, technology, and equipment in China's solar and thermal industry, but there is a "lack of policies", making it difficult for existing electricity pricing policies to reflect the value of solar and thermal projects.
