On April 21, Siemens held a digital microgrid ecosystem launch event at Siemens CNC (Nanjing) Co., Ltd. (SNC), themed “Microgrid Intelligence: Leading a Zero-Carbon Future.” During this event, Siemens announced the successful operation of its first integrated solar and storage project in its Chinese factory at SNC.
SNC has fully implemented Siemens’ comprehensive digital microgrid solution, which builds upon the operation of distributed photovoltaic systems and industrial lithium battery energy storage systems. By utilizing the optimization algorithms of the Siemens Smart ECX carbon management platform and the real-time control strategies of the SICAM A8000 microgrid controller, the facility has achieved efficient energy utilization and significantly reduced carbon emissions.
“I am pleased to see the successful operation of the integrated solar and storage project at SNC. This represents an important innovation and practice by Siemens in advancing energy management through digitalization and low-carbon technologies,” said Lin Bin, Executive Vice President of Siemens (China) Ltd. and General Manager of Siemens’ Smart Infrastructure Group in Greater China. “The successful experience of the SNC project has created a replicable digital microgrid solution that will provide valuable references for other factories and parks in optimizing source-grid-load-storage management, achieving energy savings and emissions reductions, and promoting energy transition.”
The digital microgrid solution implemented at SNC optimizes the management of the solar and storage systems. This solution employs Smart ECX and SICAM A8000 as decision-making and control units, leveraging cutting-edge technologies such as the Internet of Things and artificial intelligence. It provides comprehensive and precise energy management and carbon footprint services for the factory, which include real-time energy monitoring and analysis, carbon reduction path planning and quantification, and source-grid-load-storage optimization management. Additionally, it can utilize load forecasting models for real-time optimization of solar and storage operating modes, ensuring a 100% consumption ratio of green electricity while lowering electricity costs and carbon emissions.
Furthermore, the 1860 kW/5580 kWh high-security lithium battery energy storage system, which is a core energy facility for microgrid dispatch management at SNC, can reduce electricity costs through peak shaving and valley filling applications. During peak electricity demand in summer, this storage system can also provide stable power for the core loads of SNC for up to three hours. It is estimated that by applying Siemens’ digital microgrid solution, SNC can reduce its annual electricity expenses by approximately 250,000 yuan.
At the launch event, Siemens signed a strategic cooperation agreement with Shanghai Xinjinqiao Energy Technology Co., Ltd. (hereinafter referred to as “Xinjinqiao”). This partnership aims to promote the implementation of Xinjinqiao’s energy microgrid and low-carbon smart park operational model, leveraging the benchmark project in the Xinjinqiao industrial park. The two parties will establish a strategic partnership in areas such as energy microgrids and virtual power plants, and low-carbon smart parks, committed to the digital and low-carbon transformation of energy management and operational models in the park.
