China’s largest tidal flat photovoltaic (PV) energy storage station, constructed by China Huadian Corporation Ltd., has officially commenced operations on the salt-alkali tidal flats of the shores of Bohai Bay.
Covering an area of 18,000 mu (approximately 1,200 hectares), the project involves the installation of nearly 2 million photovoltaic panels. It integrates solar power generation with salt production, creating a synergistic industrial model that combines water-based solar power generation with the brine evaporation process for salt production.
During construction, the project prioritized ecological preservation of the tidal flats by utilizing existing salt field dikes for PV array zoning, thereby minimizing damage to the natural landscape.
As one of China’s third batch of large-scale wind and PV bases, the project boasts an installed capacity of 1,000 megawatts, supplemented by a 200 MW/400 MWh energy storage system.
The station is expected to generate 1.442 billion kWh of electricity annually, sufficient to power approximately 500,000 households. It is estimated to save 444,000 tons of standard coal each year, significantly reducing carbon emissions and contributing to the green energy transition.
With an average of over seven hours of sunlight daily, the station efficiently harnesses abundant solar energy resources. To address the intermittent and unstable nature of solar power, the station is equipped with an advanced energy storage system that stores surplus energy in batteries, ensuring reliable power supply during low sunlight periods or peak evening demand.
Acting as a green catalyst for development, the project enables local residents to share in the benefits of clean energy, achieving a dual success of ecological sustainability and economic growth.
