Maximizing Wind Power Efficiency with Energy Storage
Project Overview
To maximize the value of its high-altitude wind turbines, Wistron Corporation integrated a 752 kWh battery energy storage system (BESS) with a 400 kW PCS in a 20-foot container. The system was designed to capture excess wind generation, store it for later use, and provide a reliable power supply even when wind conditions fluctuated.
By storing surplus energy and discharging it during periods of low generation, the project improved wind power utilization, site reliability, and operational flexibility. With immersion-cooled safety design and automated control between generation and island-mode supply, this installation demonstrates how pairing energy storage with renewables can enhance efficiency, ensure stability, and enable deployment in remote locations.

Challenge
Wistron Corporation, a global ICT manufacturer, partnered with overseas developers to pioneer high-altitude wind turbines capable of capturing energy between 200–800 meters. While the technology provided access to more stable wind resources, it also introduced operational hurdles. Without energy storage, generated electricity had to be consumed immediately, limiting efficiency and flexibility. In addition, the remote nature of high-altitude sites made safety, reliability, and autonomous operation critical.
Key challenges included:
Intermittent wind generation requiring immediate consumption without storage
Inefficient utilization of renewable power without the ability to shift energy use
Need for seamless control between wind generation and island-mode power supply
Remote site location, making safety, reliability, and fire prevention essential
Requirement for an integrated design to match the unique characteristics of high-altitude wind systems
Solution
Etica deployed a 752 kWh battery energy storage system paired with a 400 kW PCS inside a 20-foot container to integrate with Wistron’s high-altitude wind turbines. The system was designed to store excess wind energy, provide stable power when wind output dropped, and operate in island mode for remote sites. Etica handled the integration of the battery cabinet, PCS mechanisms, electronics, and software to ensure seamless operation. The system was configured to:
Capture and store excess wind generation for later use
Discharge stored energy during low-wind periods to ensure reliable supply
Switch automatically between wind generation and island-mode power to serve on-site loads
Enhance site safety with immersion cooling technology, critical for remote, hard-to-service locations
Improve renewable utilization efficiency by aligning generation with actual energy demand
This solution allowed Wistron to maximize wind energy efficiency, ensure power stability at a remote site, and demonstrate how battery storage strengthens renewable integration.
Results
The BESS system improved renewable integration and site reliability:
Efficient use of wind energy by storing excess generation and discharging when needed
Stable power supply for site operations through seamless switching between wind generation and island-mode power
Enhanced safety with immersion cooling technology, critical for remote locations where emergency response is limited
Demonstrated feasibility of combining high-altitude wind power with battery storage as a replicable model for renewable projects
