Project Overview
TengQi Technology supplied PC-structure transformer panel radiators for the Chir 100MW/200MWh electrochemical energy storage station and associated booster substation project in Uzbekistan. The radiator solution was developed around the operating characteristics of energy storage transformers, including frequent charge-discharge transitions, variable thermal loads, outdoor installation conditions, transformer interface coordination, and corrosion protection requirements.
Application Background and Engineering Requirements
The Chir project is a grid-scale energy storage development comprising an electrochemical energy storage station and a supporting booster substation. In contrast to applications operating under relatively steady loads, energy storage systems experience repeated charging, discharging, and power-regulation cycles. These operating conditions can cause transformer loading and temperature rise to change frequently over time.
Located in a temperate continental climate, the project also requires equipment suitable for outdoor exposure and substantial day-to-night temperature variation. For the transformer radiator package, the engineering focus included thermal management compatibility, structural durability, surface protection, and alignment with the transformer tank interface and installation arrangement.

Solution Approach
Oil Channel Design for Variable-Load Operation
The radiator design incorporated oil channel optimization in coordination with the thermal management requirements of the energy storage transformer. This design approach supports oil circulation and heat transfer during changing load conditions, helping the radiator assembly maintain its intended cooling function as transformer temperature rise varies through charging and discharging cycles.
Outdoor Corrosion Protection Configuration
A B05 coating system with a total dry film thickness of 200 μm was specified for the project, with corrosion protection capability up to C5-M level. The coating configuration was selected to strengthen surface protection for outdoor equipment exposed to humidity, temperature variation, and potential corrosive influences.
Actual suitability for a specific corrosivity category depends on local environmental conditions, customer specifications, coating quality control, transportation and installation practices, and subsequent maintenance arrangements.
Transformer Interface and Installation Coordination
As an external cooling component of an oil-immersed transformer, the panel radiator must align with the transformer tank interface, mounting location, and overall equipment layout. The Chir project radiator package was coordinated with the transformer connection requirements to support installation, system integration, and future inspection and maintenance activities.
Project Relevance for Energy Storage Infrastructure
- Thermal management support: The configuration addresses the cooling requirements associated with variable-load transformer operation in electrochemical energy storage applications.
- Outdoor durability considerations: The coating system integrates corrosion protection requirements into the radiator package for outdoor booster substation conditions.
- Coordinated equipment integration: Combining cooling, interface matching, and surface protection requirements within one radiator solution helps improve technical continuity across manufacturing, installation, and maintenance stages.
- Applicability to renewable power projects: The project demonstrates the role of transformer panel radiators in energy storage station and booster substation equipment integration where thermal cycling and environmental exposure require focused engineering consideration.
