Core Viewpoint - The article highlights the successful grid connection of Jiangsu's largest aquaculture photovoltaic project, which integrates solar power generation with aquaculture, promoting both clean energy and ecological farming [1][5]. Group 1: Project Overview - The first phase of the project, located in Lusi Port Town, Qidong City, has a total installed capacity of 400 MW and is expected to generate an average annual power output of 490 million kWh over a 25-year operational period [2][3]. - The project utilizes approximately 5,850 acres of tidal flat area and consists of 121 photovoltaic units, each with a capacity of 3.3 MW, connected to the shore via a cable corridor [3]. Group 2: Environmental Impact - The project is projected to reduce carbon dioxide emissions by approximately 490,000 tons annually, contributing to environmental sustainability [3]. Group 3: Innovative Model - This large-scale tidal flat photovoltaic project adopts a "water-based power generation and underwater aquaculture" model, efficiently utilizing tidal flat resources while integrating clean energy with ecological farming [5].
