China Nylon City Launches First Phase Grid Connection of 100MW/400MWh Vanadium Flow Battery Energy Storage Project

China’s rapid industrialisation of vanadium flow battery (VFB) technology has recorded another major milestone with the successful first-phase grid connection of the China Nylon City Source-Grid-Load-Storage Integrated Vanadium Flow Battery Energy Storage Project in Pingdingshan, Henan Province.

Designed for a total installed capacity of 100MW/400MWh, the project is among the newest wave of utility-scale vanadium flow battery systems now entering live operation as China accelerates deployment of long-duration storage across industrial parks, incremental distribution networks and renewable energy balancing applications. 

The first operational phase completed commissioning, grid acceptance and synchronisation testing on 29 April 2026, before successfully entering service under dispatch from Pingdingshan Nylon City Power Co., Ltd., formally connecting the installation to the park’s dedicated incremental power distribution network. Developed by Nylon Construction Investment Company, the project has been designated as one of Henan Province’s strategic low-carbon energy infrastructure initiatives under China’s national “dual carbon” policy framework. 

A New Large-Scale Benchmark for Long-Duration Industrial Storage

Planned under a phased implementation model, the China Nylon City facility will ultimately deliver 400MWh of vanadium flow battery storage, supported by:

  • intelligent power conversion and booster systems,
  • integrated digital control and O&M infrastructure,
  • direct interaction with industrial park load centres, and
  • participation in the regional source-grid-load-storage operating platform. 

Unlike merchant standalone battery projects, the installation has been designed as a multi-functional industrial energy asset capable of simultaneously delivering:

  • renewable energy absorption,
  • peak shaving and valley filling,
  • reserve balancing,
  • emergency backup support, and
  • electricity cost optimisation for industrial users.

The project therefore reflects a major structural evolution in China’s use of vanadium flow batteries—from isolated demonstration facilities toward deeply embedded industrial grid infrastructure.

China’s “Source-Grid-Load-Storage” Model Is Creating a Natural Growth Platform for Vanadium

The strategic significance of the Nylon City project lies in its role inside China’s rapidly expanding “Source-Grid-Load-Storage” integrated energy model, in which local renewable generation, industrial demand management, smart distribution systems and utility-scale storage are coordinated within one operating ecosystem.

Within this framework, the vanadium flow battery system will:

Capture and Shift Renewable Power

Surplus photovoltaic and other intermittent clean electricity generated within the industrial cluster can be stored and redeployed during higher demand periods, materially reducing renewable curtailment.

Stabilise Industrial Grid Operations

Through dispatchable balancing, reserve response and emergency support, the battery system will improve power quality, flexibility and operational security across the Nylon City distribution network.

Reduce Comprehensive Electricity Costs

By smoothing demand peaks and optimising energy usage patterns, the installation is expected to improve the long-term electricity economics of manufacturers operating within the industrial park. 

This duty profile aligns closely with the technical strengths of vanadium flow batteries, particularly where operators require:

  • long-duration daily cycling,
  • ultra-high operational safety,
  • long calendar life,
  • deep discharge flexibility, and
  • low long-term replacement risk.

Construction Progressing Toward Full 400MWh Commercial Operation

Following successful energisation of the first stage, project developers confirmed that installation and commissioning of the remaining storage units will continue on an accelerated schedule, with full-capacity operation targeted in the next phase of project delivery. 

Once fully operational, the China Nylon City facility is expected to become one of Henan Province’s flagship examples of integrated industrial renewable-storage deployment and a further demonstration of China’s accelerating confidence in utility-scale vanadium energy storage.
