Fossil Fuels have a significant impact on small island countries in the Pacific. Sustainable developments are key for the development of these countries. One such strategy involves using renewable energy resources that are locally available. This paper focuses on a feasibility study for a sustainable campus at the National University of Samoa using a grid connected PV system.
Information from eight years of historical energy consumption, seven weeks of energy load profile data and the potential rooftops of buildings for the two campuses (upper and lower) were analysed using RETScreen and HOMER software.
The pre-feasibility study by RETScreen revealed that it is possible to offset all the university electricity consumptions from solar panels from all the university rooftops buildings to achieve sustainable campus. Also, the HOMER feasibility analysis for 25 years shows that it is economically viable for the university to have its electricity supplied by a grid connected PV system. This is based on the feed-in-tariff of $0.25 AUD, electricity retail price of $0.50 AUD, a real interest rate of 8%, the average market price of the PV panel, battery and inverter.
However, it is not technically possible for the university to have such a system, due to the utility requirements unless energy storage is used. HOMER simulation revealed that system with batteries become more expensive and uneconomical for the university.
It is recommended that a strong support from the government is required for the National University of Samoa in order to achieve a sustainable campus through the use of a grid connected PV system. Also, more research is needed in the area of electrical energy storage in order to increase the solar PV penetration onto the diesel utility grid in the country.
