In Xinyang, Henan, where renewable energy penetration exceeds 62%, the dense precision manufacturing clusters (electronics and optical devices) require ultra-stable power quality. As one of Henan Province's first independent energy storage demonstration projects, this 100MW/200MWh immersion-cooled station — powered by Kortrong's core system solutions — has achieved over 500 days of safe, zero-incident operation since grid connection. It has become a vital enabler for high-proportion renewable integration and reliable power supply for sensitive loads.
This is Central China's largest immersion-cooled independent energy storage project by scale. Kortrong deployed 20 sets of self-developed
5MW/10MWh Immersion-Cooled Battery Container.
By fully submerging battery cells in dielectric coolant, the technology physically isolates oxygen and eliminates thermal runaway risks at the source — shifting safety philosophy from traditional “passive fire protection” to cell-level “intrinsic immunity.”
The dynamic flow immersion cooling maintains inter-cell temperature differences below 2°C, effectively minimizing localized aging and internal short-circuit risks while extending system lifespan and protecting long-term asset value.
As immersion cooling scales to hundred-megawatt-hour levels, industry focus has moved beyond “Is it safe?” to “Can it deliver long-term, stable, and high-performance operation in complex grid environments?” This demands strong end-to-end capabilities in electrical compatibility, station-level thermal management, and grid response.
With full-stack self-developed technology, Kortrong has built a significant technical barrier in system coordination and reliability, fully realizing the intrinsic safety advantages of immersion cooling at utility scale.
In high-renewable grids, competition centers on lifecycle cost per kWh. Every efficiency improvement directly impacts returns.
Kortrong's solution adopts a box-type transformer + AC-DC integrated immersion-cooled system with independent cluster control. This architecture eliminates inter-cluster circulating currents, increasing depth of discharge (DoD) by 5% versus conventional systems.
Combined with the superior temperature uniformity of immersion cooling, the system minimizes auxiliary power consumption and unlocks greater potential of pack-level management — achieving optimal overall efficiency and delivering measurable ROI advantages.
Kortrong's cell-level intelligent energy management system breaks data silos to enable smart decision-making, automatic regulation, and full coordination.
Powered by reinforcement learning algorithms, it continuously optimizes ancillary service strategies while accumulating rich operational data across source-grid-load-storage applications.
This has established a complete spot market trading closed loop — from electricity price forecasting and strategy generation to trade execution and post-trade optimization — supporting integrated operation of spot trading, ancillary services, and medium-to-long-term contracts. The system elevates energy storage from basic strategy execution to sophisticated asset management.
Cloud-based predictive maintenance further enhances safety through early fault warning and precise positioning.
The Xinyang project has markedly strengthened local grid peaking capability and serves as a practical benchmark for China's new energy storage sector.
Looking ahead, Kortrong will continue to focus on customer needs, delivering high-quality products and services to advance the renewable-dominated new power system.
