In a landmark project demonstrating the commercial viability of sodium-ion technology, a 50 MWh sodium-ion battery energy storage system was deployed at an industrial park in Jiangsu Province, China, successfully reducing energy costs by 35% while improving grid stability.
Project Overview
The industrial park, housing over 20 manufacturing facilities with a combined peak demand of 15 MW, required a cost-effective energy storage solution to manage peak demand charges and integrate on-site solar generation.
Solution
A containerized sodium-ion battery system was deployed, providing 10 MW / 50 MWh of storage capacity. The system performs peak shaving, load shifting, and frequency regulation services.
Results
- 35% reduction in electricity costs through peak shaving
- 92% round-trip efficiency
- Over 2,000 operational hours with zero safety incidents
- Projected ROI of 4.5 years
