1. Project Overview

Located in Lianyungang City, Jiangsu Province, China.

This represents the nation’s largest single-site ‘fish-solar complementary’ photovoltaic power generation project (total installed capacity: 940MW).

A supporting 94MW/188MWh lithium iron phosphate energy storage power station has been constructed to enhance renewable energy integration capacity and grid stability.

On 19 November 2024, the first phase of the project successfully connected to the grid.

Shanghai Huijue Technology provided the integrated solution and key equipment for the energy storage system.
