Abstract
This research work presents the reliability assessment of electrical load distribution system in Federal University of Petroleum Resources, Effurun (FUPRE), Warri using the Analytical method and ETAP software as the simulation tool to run the reliability assessment of the System. The analytical analysis was conceded out by using August 2018 – August 2019 historical data of Tetfund Classrooms Blocks, Hostels, College of Technology, Administration Block, Health Center, and College of Science Feeder obtained from the Benin Electricity Distribution Company [BEDC]. The results conceded revealed that College of Technology Injection Substation is the most reliable in the distribution network when compared to the other five substations around the institution premises as it recorded system indices of ASAI: 99.30, SAIFI: 1.10, SAIDI: 55.35, CAIDI: 123.04 in August 2018 to August 2019. Nevertheless, the total reliability indices of the six substations under investigation as obtained from the analysis, and it shows that availability of power to FUPRE distribution is very poor as compared with the benchmark of IEEE ASAI of 99.99 for distribution substation availability.

Security of power system reflects the capacity to respond to disturbances, the safety of a power distribution system relates to the system vibrant response and can be through unique studies [2]
Summary
Reliable electric power supply is the bases for modern society. The fundamental capacity of a distribution system is to supply constant electricity to its customers at optimal operating costs with the affirmation of a reasonable quality and congruity consistently at all times. Power system reliability depicts the general capacity of the distribution system to execute its purpose sufficiently. Power distribution system reliability discussions are divided into two separate perspectives, security and sufficiency [1]. Acceptability of a power distribution system is identified to static conditions, and is normally evaluated through power flow simulation studies. Security of power system reflects the capacity to respond to disturbances, the safety of a power distribution system relates to the system vibrant response and can be through unique studies [2]
