On May 13, it was learned from CNNC Jiangsu New Energy Co., Ltd. that the sea use for the CNNC Tianwan 2 million kW tidal flat photovoltaic demonstration project has been approved by the State Council, covering an area of 1,875.7761 hectares (about 28,000 mu), with a total investment of about 9 billion yuan, making it the largest offshore photovoltaic project in China.

It’s understood that the project is located in the area of thermal discharge water of the Tianwan Nuclear Power Station in Lianyun District of our city. It is characterized by novelty, tight schedule, heavy tasks, and strong professionalism. The project team is equipped with over 30 professional technicians in marine, ecological, environmental, and fishery fields. In just one year, they completed the preliminary work such as project planning, site selection optimization, and resource and environmental investigations. They also conducted analyses and predictions of hydrodynamic conditions, erosion and deposition, water quality, sediment environment, as well as the impact on the diffusion of thermal discharge water from the nuclear power plant. Additionally, they conducted special studies and assessments on the impact of the project on resources such as birds, shorelines, wetlands and sea areas, demonstrating the practice of three-dimensional layered authorization for sea use and maximizing the benefits of marine resources.

This project is one of the first batch of offshore photovoltaic projects to be submitted to the State Council for approval in China. It is also the largest maritime project with three-dimensional layered authorization for sea use covering the largest sea area in China. The sea use type is for electric power industry, with a duration of 27 years. It is intended for the construction of photovoltaic arrays and their supporting facilities. All sea use spatial layers are water surfaces, and it will be used in a three-dimensional and composite manner with the ed Tianwan Nuclear Power Plant’s warm water discharge area. This is a specific measure taken by our province to implement the Natural Resources Ministry’s Notice on Exploring and Promoting the Work of Three-Dimensional Layered Authorization for Sea Use. It is also a vivid practice in implementing the Natural Resources Ministry’s offshore photovoltaic policy. The supporting energy storage project has entered the final stage of construction, and the supporting engineering is expected to be completed and put into operation by the end of June.

A relevant official from the Provincial Natural Resources Department introduced that after the completion of the project, it can provide 2 billion kilowatt-hours of clean energy annually, save about 795,000 tons of standard coal annually, and reduce carbon dioxide emissions by 609,600 tons annually. The approval of the project has high application value and positive demonstration significance for building a nuclear-photovoltaic integrated green power demonstration base, adjusting regional energy structure, intensively and scientifically utilizing shallow beach resources to develop clean energy industry.
