Abstract-This paper presents a proposed hybrid system based on diesel generator and solar photovoltaic (PV) as an effective option to power a small remote community. The cost of running diesel generator speedily due to erratic power supply in a small remote community that is not grid connected is highly expensive and not environmentally friendly. A solar PV was used to reduce or augment the continuous diesel generator sets, resulting in reduced cost of operation and maintenance. A proper solar radiation data and sizing based on the specification of the PV system and battery bank was done. In addition, a comparative study was carried out considering two scenarios of the proposed model system. In the first scenario, the diesel generation, solar PV system was treated as autonomous (or standalone). In the second scenario, the proposed model system was connected to the grid system. It is discovered that powering the small remote community with the proposed hybrid system is much more beneficial and encourages competition with other conventional energy sources, because it minimizes both operating costs and pollutants emissions. Furthermore, analysis results obtain from HOMER software shows that is promising to implement the on-grid system.

Sequel to the trend of the epileptic nature of electricity power supply in some part of the country, this paper provides a maintainability model for this problem in Uyo. Different statistical test were employed in the work. The data was subjected to both descriptive and inferential analysis. It was observed that the set of outage data used in the research were identically and independently distributed. Different distributions were tested to obtain the best fitted distribution. Hence the maintainability model for the total outage power data was proposed as, . Furthermore, it was observed that the lognormal distribution was the best distribution to model the maintainability of the electric power supply in Uyo.
