Abstract

Electricity has become one of human basic needs beside food and water. The demands increase significantly with rapid industries and advance technology development. Currently, Malaysia is depending mostly on fossil fuels to generate electricity particularly from natural gas which will eventually deplete soon. However, the process of generating electricity extensively from fossil fuels produce greenhouse gas especially carbon dioxide. Therefore, a sustainable electricity generation is required. One sources of energy that started to get attention is biogas release from sewage treatment plant (STP) which contains up to 70 % methane. Unfortunately, the biogas is commonly flared or release to atmosphere. The main objective of this study is to develop multi-period planning of centralized sewage treatment plant (CSTP) for electricity generation in Iskandar Malaysia. It can be divided into 5 stages; problem formulation and superstructure construction, data gathering, mathematical modelling, General Algebraic Modeling System (GAMS) coding and result analysis. This model is used to propose the optimal network and location to build CSTP which can meet electricity demand.
