China's largest 'Linear Fresnel' solar thermal energy project connected to grid

Date: 2024-12-23

On December 22, CTG's Hami 1GW 'Solar Thermal + Photovoltaic' Integrated Energy Demonstration Project—China's largest 'Linear Fresnel' solar thermal energy project—was successfully connected to the grid.

Located in Hami city, northwest China's Xinjiang Uygur Autonomous Region, this project boasts a total installed capacity of 1GW, comprising a 100MW 'Linear Fresnel' solar thermal energy storage power station and a 900MW photovoltaic station.

The photovoltaic station is now fully operational, and the construction of the solar thermal energy storage power station is still underway.

Once fully connected, the solar thermal energy storage power station will enhance grid stability by providing critical frequency and peak regulation, forming a complementary clean energy hub with the photovoltaic station.

The project is expected to generate approximately 1.86 billion kWh of electricity annually, saving about 558,700 tonnes of standard coal and reducing carbon emissions by over 1.5 million tonnes each year.

The "Linear Fresnel" technology is one of the most advanced approaches in solar thermal energy storage. It leverages light reflection and refraction, enabling the "Solar Thermal + Photovoltaic" system to generate electricity with photovoltaics during the day and with solar thermal energy at night. This ensures stable and controllable power output, enhancing the grid's capacity to accommodate renewable energy.
