SMRAAD’s 6kW L-Type Wind Turbines Power Smart, Sustainable Streets in Tongli

In the historic water town of Tongli, Suzhou, a modern energy revolution is unfolding along its scenic pathways. In 2026, SMRAAD, in partnership with State Grid Jiangsu, completed an innovative distributed energy system that blends tradition with cutting-edge technology. The project features 6kW L-type vertical axis wind turbines integrated with commercial energy storage cabinets, providing clean, reliable power to the town’s smart streetlights and electronic information displays, as vividly captured in the photograph.
The system is a masterclass in urban sustainability. The L-type turbines, with their compact vertical design, are perfectly suited to Tongli’s gentle, variable winds, operating silently and efficiently without disrupting the town’s tranquil ambiance. The energy they generate is stored in robust, grid-connected battery cabinets, ensuring a steady power supply even during calm periods. This stored energy directly powers the sleek, modern streetlights and digital displays that line the pedestrian paths, enhancing safety and visitor experience while eliminating the need for fossil fuel-based grid power.
For Tongli, this project is more than an infrastructure upgrade—it’s a statement of environmental stewardship. The 6kW turbines are projected to generate over 13,000 kWh of clean electricity annually, reducing the town’s carbon footprint by approximately 10 metric tons each year. By harnessing local wind resources, Tongli is not only cutting emissions but also showcasing how renewable energy can be seamlessly woven into the fabric of a historic community.
“Tongli’s charm lies in its balance of old and new,” said a SMRAAD project engineer. “This wind-storage system allows us to preserve that balance while powering the town’s future with clean, smart energy. It’s a model for how heritage sites can lead the way in sustainability.”
This Tongli project solidifies SMRAAD’s reputation for delivering tailored, future-ready energy solutions. By combining L-type wind technology with commercial energy storage, we’ve created a blueprint for smart, sustainable urban infrastructure that respects the past while embracing the future.
