China Energy Engineering Group Tianjin Electric Power Construction Co., Ltd. has commenced construction of the Tianjin TEDA Integrated Energy long-duration energy storage power station project, a grid-side facility designed to strengthen the region’s incremental distribution network and accelerate the development of a modern, distributed “source–grid–load–storage” smart power system in the Tianjin Economic-Technological Development Area.
Located on Xintai Street in the Tianjin Economic-Technological Development Area, the project will deploy a multi-technology energy storage portfolio—including vanadium flow battery (VFB) systems, alongside lead-carbon and solid-state battery technologies—to balance safety, sustainability, and performance for long-duration grid support.
Project scale and key specifications
- Power (rated): 177 MW
- Energy capacity: 1,052.93 MWh
- Voltage level: 10/35 kV
- Site footprint: 27,900 m²; building area: 28,900 m²; 3 above-ground floors (no basement); max height 23.934 m
The project is being developed by Tianjin TEDA Comprehensive Energy Service Co., Ltd. (wholly owned by Tianjin TEDA Electric Power Co., Ltd.), and constructed by China Energy Engineering Group Tianjin Electric Power Construction Co., Ltd.
As a core component of the site’s diversified technology mix, vanadium flow batteries are well suited for long-duration energy storage applications that support the power system with peak shaving, frequency regulation, and backup services—helping relieve peak load pressure and enabling greater integration of renewable energy.
Unlike conventional batteries that store energy in fixed electrodes, VFBs store energy in liquid electrolytes, offering advantages that are particularly attractive for utility-scale deployments: robust operational safety characteristics, scalable energy capacity, and strong suitability for high-cycle, long-service applications—aligning with the project’s goal of providing dependable, environmentally responsible grid support.
Upon completion, the Tianjin TEDA project is expected to provide critical grid-side flexibility—supporting renewable energy consumption (curtailment reduction), strengthening system resilience, and helping drive regional energy structure optimization and green transition.
