In this article, a closed-loop industrial plant energy evaluation and planning system with a WSN architecture has been proposed. This system eliminates the costs associated with the installation and maintenance of communication cables. The scheme outlined has been implemented in a simplified prototype WSN system, and its industrial feasibility has been verified by the experimental results. The main contributions of this system lie in its nonintrusive, intelligent, and low-cost nature. The efficiency and operating cost of the plant are estimated nonintrusively. The use of speed and torque transducers is eliminated. The motor's normal operation is not impeded. The deployment of a WSN makes high-level intelligent power management feasible
