Cogeneration or more popularly known as combine heat and power (CHP) refers to the sequential generation of thermal and electrical energy from the same amount of fuel input within a manufacturing process. This form of generation enhances the utilization of energy efficiently and is highly promoted by the Malaysian Government. Energy efficiency could be increased from 35% to 75 – 80% using this mode of generation. The Energy Commission (EC) had issued more than 26 licenses to major developers in the petrochemical, chemical, steel, refinery, pulp and paper, and district cooling industries to generate electricity as part of their manufacturing processes. The total generating capacity is 645.8 MW, which represents less than 6% of the maximum demand of Peninsular Malaysia. Most of this cogeneration plants uses either natural gas or process waste gas as the main source of fuel. |
