This paper is on the performance analysis of photovoltaic (PV) system integrated into an islanded Nigeria electricity grid. Electricity supply in Nigeria is abysmal and the effects on the economy and quality of life of Nigerians. This work carried out load flow studies of a part of the existing network, namely Afam Power Substation to Yenegoa Transmission Substation and the network with utility scale PV system integrated. Contingency analysis of the system was carried out using a set of possible contingency scenarios. PowerWorld Simulator was deployed in carrying out these analyses. With the incorporation of PV systems, stability was achieved when there was loss of generation. For example, when Afam Generation station was opened, system violations went from 14 (without PV) to 3 (with PV). Finally, the levelized cost of electricity (LCoE) for combined cycle gas turbines and PV systems was conducted. The LCoE for PV systems was 0.08985$/KWh which is less than LCoE of 0.245$/KWh as at 2013. The results also show that such hybrid generation planning can provide a high degree of redundancy in our fragile network
