“It’s not that Taiwanese factories don’t want to save energy; they just don’t know how.” In a recent interview, KAI-YI CHANG, Founder and Chairman of HYES, pointed out a common paradox facing Taiwanese enterprises: while electricity costs rise and ESG pressures intensify annually, most companies remain uncertain about where to begin their efficiency journey.
Having spent over a decade traversing various industrial zones, KAI-YI CHANG observed a recurring phenomenon: motors, inverters, and machinery all appear to be functioning normally, yet overall power consumption remains inexplicably high. “In many cases, it’s not that the equipment itself is inefficient—it’s that poor Power Quality is forcing the equipment to consume excess power,” KAI-YI CHANG explains.
Energy Efficiency: Reducing “Forced Power Consumption” True energy saving is not just about replacing equipment; it is about ensuring that machinery is no longer “forced” to overwork. The reactor filtering technology introduced by HYES is designed to mitigate high-order harmonics, three-phase imbalance, and voltage surges, restoring power to a “clean” and stable state. When equipment is no longer disrupted by electrical noise and interference, the load naturally decreases, leading to lower energy consumption.
Over the past year, HYES has assisted numerous factories in the electronics, metalworking, chemical, and plastics industries in completing energy-saving verification. These projects typically achieve energy reduction rates exceeding 12%, with some large-scale industrial chains surpassing 18%. Crucially, all data is verified by third parties. “Energy saving must be based on evidence, not intuition,” KAI-YI CHANG states.
Energy Baselines: “Walking into the Factory to See the Truth” The most critical phase of the HYES process is establishing an Energy Baseline. KAI-YI CHANG emphasizes that a baseline is more than just a graph of meter readings; it requires a deep understanding of the energy characteristics of every production process.
He shares an example where an initial baseline model for a factory failed to yield accurate predictions. After a deep-dive analysis, it was discovered that the plant’s production data included defective products, which skewed the perceived energy efficiency. Once the baseline was adjusted to reflect actual output, the energy-saving results became immediately clear and more credible.
An Integrated Strategy: From Energy Saving to Sustainability Beyond power quality improvement, HYES utilizes its EMS (Energy Management System) platform to help factories monitor power fluctuations. The company also provides a comprehensive suite of services, including solar energy installation, Renewable Energy Certificate (REC) procurement, carbon footprint verification, and government subsidy application assistance.
KAI-YI CHANG believes that energy efficiency and sustainability are now inextricably linked. “Energy efficiency lowers costs, while sustainability ensures a company remains in the global supply chain,” he notes. With the upcoming implementation of CBAM and carbon fees, precise energy management will be the only way for businesses to adapt successfully.
KAI-YI CHANG concludes that HYES’s role is not merely selling hardware, but helping enterprises “achieve energy efficiency and net-zero requirements in the most cost-effective way.” True sustainable competitiveness comes from making energy savings visible, verifiable, and long-lasting.
