On 30 December, the Inner Mongolia Energy Group proudly announced the successful grid connection of its landmark Dengkou 605 MW/1410 MWh Energy Storage Project. This cutting-edge facility, the largest independent energy storage power station in China, integrates state-of-the-art flow and electrochemical storage systems, setting a new standard for renewable energy solutions.

Key Project Highlights

The Dengkou Energy Storage Project showcases a dual energy storage system:

  • Lithium Iron Phosphate (LFP) Batteries: A 505 MW/1010 MWh system.
  • Vanadium Flow Batteries (VFB): A 100 MW/400 MWh system, divided into two 50 MW/200 MWh packages:
    • Package 1: Awarded to Shanghai Electric (Anhui) Energy Storage Technology Co., Ltd., valued at ¥403.96 million (¥2.0198/Wh).
    • Package 2: Awarded to V-Liquid Energy Co., Ltd., valued at ¥434.6 million (¥2.173/Wh).

The vanadium flow battery technology provides unmatched safety, long-duration energy storage, high cycle efficiency, and extended lifespan. Once fully operational, this system will enhance grid stability and reliability while advancing renewable energy adoption and utilization.

Engineering Excellence

The project's construction process adopted an innovative approach to excavation and installation, focusing on precision and efficiency. The team meticulously designed site-level systems, including piping, cabling, foundations, and grounding. A multi-layer strategy enabled seamless installation and backfilling, ensuring timely completion and operational readiness.

A Vision for Renewable Energy

This groundbreaking initiative marks a significant milestone in renewable energy infrastructure. It highlights the Inner Mongolia Energy Group’s dedication to innovation and sustainable development while demonstrating how large-scale energy storage can catalyze the global transition to renewable energy.
