Siemens Energy offers E-STATCOM and Storage solutions specifically designed to meet the unique needs of AI datacenter grid connections. The number of AI datacenters is increasing rapidly, leading to several challenges: increased power demand leads to voltage instabilities, and extreme power fluctuations of AI datacenters can lead to damage of nearby equipment (e.g. gas-turbines).
In response, the flyer recognizes the following critical factors: the rapid increase in the number of AI datacenters is driving up energy requirements; individual datacenters have high energy demands, contributing to fluctuating loads that heighten the risk of grid instability; and ensuring power quality is essential to protect existing assets, while voltage and angle stability are crucial for reliable grid operation.
The modular E-STATCOM solution ensures power quality by addressing both voltage stability and AI datacenter load fluctuations. Its adaptable design allows it to effectively respond to the planning uncertainties associated with datacenter construction, providing a robust framework for AI infrastructure management. By reducing peak load demands, the system can lower the overall connection costs for datacenters.
Additionally, the Qstor Battery Energy Storage System ensures uninterrupted operations, improves power quality, and supports energy efficiency by demand response, peak shaving, and renewable energy integration. It serves as a safeguard against power outages and fluctuations.
Siemens Energy offers a wide range of digital solutions: securing the most valuable infrastructure and core operations with digital control and protection; leveraging asset digitalization for advanced software-based monitoring and diagnostics solutions; and advisory services to address challenges like voltage stability, grid code compliance and reliability — including a fully compliant grid connection concept for the data center and end-to-end cybersecurity solutions.
And what's more: comprehensive service packages for all energy supply equipment and 24/7 access to the technical experts hotline.
