Four-level Classification System
The four-level classification system divides all companies submitting periodic reports under the Energy Conservation Act into four classes (S, A, B and C) and implements a more vigorous response according to the class.
Since the start of the System, OTC has maintained 'S Class' status, meaning it is an 'excellent energy saver', for all periodic reports up to 2022.
