Abstract

The increase in the prices and consumption of electricity has increased the energy bills of many public buildings, including public schools and boarding schools. Thus, improving energy efficiency and energy conservation by developing methods to promote renewable energy (RE) for electricity generation has become increasingly important. The issue of Greenhouse Gases (GHG) emissions is also an important consideration in this research.

This dissertation describes electricity consumption in West Java and Indonesia. In particular, the trend in electricity consumption at the Baiturrahman Boarding School has been analysed by calculating detailed energy consumption for various appliances and works at the school. An energy audit was undertaken, with further specific investigation into water pumping, lighting and refrigeration. Consequently, recommendations include replacement of the existing water pump, reducing the operational time of the lighting system and regular maintenance of the refrigeration to improve the electricity consumption of the school in this case study. Replacing the existing pump with a smaller size pump and reducing the hours of operation to 12 hours resulted in 7.4 MWh electricity or 8.65% of total estimated electricity consumption—a saving of $1,005.21 with a payback period of 0.5 years.

An analysis of electricity generation using RE resources was also conducted using RETScreen and HOMER software. The possibility of implementing wind, solar PV and micro hydro along with grid electricity was considered. This resulted in the recommendation to use 69% micro hydro and 31% electricity grid to supply the boarding school, in order to meet 100% of load with COE of $0.083/kWh, which is almost half of the current electricity rate.
