Company Overview

GREAT is a Taiwan-based green energy integrator specializing in energy storage systems, battery design and manufacturing, and integrated energy applications, delivering enterprise-level energy services. With extensive experience in battery systems and energy engineering, GREAT has developed strong capabilities across battery modules, energy storage systems, low-carbon cold chain logistics, circular economy applications, and diverse green energy sectors. We provide highly integrated and practical approaches tailored to different industries and application scenarios. Our team brings years of hands-on project execution and system integration experience, starting from overall energy architecture planning. By integrating battery technologies, system design and manufacturing, engineering implementation, as well as Battery Management Systems (BMS) and Energy Management Systems (EMS), we deliver high-quality systems that ensure safety, performance, reliability, and long-term stable operation. In the field of energy storage, GREAT offers a one-stop integration capability covering feasibility assessment, system design and manufacturing, engineering construction, and long-term operation and maintenance. By incorporating high-efficiency charging and storage systems and intelligent energy management technologies, we help clients improve energy efficiency, enhance power resilience, and reduce operational costs and carbon risks. These systems can also serve as key energy nodes for net-zero cities, supporting Vehicle-to-Grid (V2G) applications and integrating with smart street lighting, smart poles, and distributed energy architectures to enable microgrids and city-level energy management. In low-carbon cold chain logistics, GREAT focuses on rear-compartment system integration for refrigerated vehicles, combining battery modules and energy management mechanisms to improve transport efficiency and reduce energy consumption. These applications support logistics and supply chain operations while also extending to urban distribution, low-carbon transportation, and sustainable city infrastructure. In the circular economy sector, GREAT is among the earliest teams in Taiwan to implement second-life applications of retired electric bus batteries and successfully deploy them in energy storage systems. We possess full capabilities in battery evaluation, grading, system integration, and safety management, with proven project experience including collaboration with publicly listed company Allis Electric Co., Ltd. As the energy industry evolves rapidly, GREAT continues to invest in technological advancement. In addition to lithium-ion batteries, we are actively developing next-generation battery technologies such as sodium-ion systems and transforming them into practical, deployable applications. With extensive experience across battery systems, energy storage engineering, and green energy industries, GREAT is a trusted long-term partner for enterprises, industrial clients, and city stakeholders in energy transition and sustainable development.
