Lianyungang, Ganyu – November 19, 2024 – The first phase of China’s largest single-unit scale “fishing-photovoltaic complementary” solar power project, Hengdian DMEGC Lianyungang Ganyu Dongshang Photovoltaic Power Generation Project, has successfully been connected to the grid. Roche Energy provided the critical energy storage equipment and system solutions for this project, offering strong support for the coordinated operation of the photovoltaic generation and energy storage systems. The successful grid connection of this project is of great significance for optimizing the regional energy structure and achieving the “dual carbon” goals.
Energy Storage and Photovoltaic Synergy: Empowering the Green Energy Transition
Hengdian Group DMEGC Magnetics Co., Ltd. (referred to as “DMEGC”, stock ticker 002056.SZ) has invested in and constructed the country’s largest single-unit “fishing-photovoltaic complementary” 940MW photovoltaic power project at the Lianyungang Ganyu Dongshang photovoltaic station. The first batch of capacity has successfully been connected to the grid and is generating electricity. The project also includes the construction of a 94MW/188MWh lithium iron phosphate (LiFePO4) energy storage station to enhance the stability of photovoltaic power generation and the dispatching capability of the grid. Roche Energy provided the project with a standardized 20-foot containerized energy storage solution, featuring a large pack design with 104 battery cells, each with a capacity of 5.015MWh. The solution was delivered with high quality within one month, supporting peak-shaving, frequency regulation, grid dispatch, and other functions, ensuring stable system operation.
Modular Design: Efficient Delivery and Operation
The containerized energy storage system adopts a modular design, significantly improving manufacturing, installation, and maintenance efficiency. Roche Energy provided a string-based solution design by connecting storage batteries in series into multiple modules, optimizing the system’s flexibility, manageability, and operational efficiency. The equipment integrates key components, including energy storage power conversion systems (PCS), energy storage batteries, primary systems, monitoring systems, fire protection systems, and temperature control systems, meeting the requirements for efficient operation and safety.
A Benchmark Demonstration: Leading the Future of the Energy Storage Industry
Roche Energy was involved in the project from the very beginning, ensuring optimal performance of the energy storage equipment under complex grid conditions. The successful grid connection of this first phase project is of great significance for regional renewable energy development and energy structure optimization, while also providing a demonstration case for the integration of fishing-photovoltaic complementary systems with energy storage. In the future, Roche Energy will continue to focus on the research and development of energy storage technologies and the implementation of projects, providing more efficient and reliable energy storage solutions to support the sustainable development of the renewable energy industry.
