Simulation Study on Energy Mix for Power Generation in Temburong Eco Town

Abstract

There is an eco town development plan in Temburong District, Brunei Darussalam. The eco town concept is about applying energy efficiency technologies to achieve lower energy demand, especially electricity, to be used by buildings, and renewable energy such as solar photovoltaic (PV). At the request of the Ministry of Energy and Industry (MEI), Brunei Darussalam, ERIA conducted a research study. The study measured the impact of the application of energy efficiency technologies for buildings and installation of solar PV with electricity storage as power supply system based on the Temburong district development plan prepared by Town and City Planning Department under the Ministry of Development (MOD). For energy efficiency technologies for buildings, ERIA applied two types of building energy intensity (BEI): (i) normal township (ordinary BEI) and (ii) eco township (green BEI, like Green Building Index in Malaysia). In Temburong District, several types of buildings – office, hotel, shopping mall, hospital, and others – will be constructed based on the Temburong district plan. If MOD could apply the eco township (GBI), electricity demand would be reduced by 30% from the normal township, which is a significant effect. In general, if buildings could apply the eco township (GBI), construction cost would be higher than that of the normal township, but power generation cost could be saved due to lower electricity demand. Focusing on initial cost of solar PV and storage, the eco township (GBI) will contribute a reduction of about US$ 100 million compared with the normal township.
