The Nigeria 330KV integrated power network consisting of 52 buses, 64 transmission lines and sixteen generating stations was studied. The network was subjected to different reactive power loadings ranging from 25%, 50%, 75%, 100%, 125% and 150% respectively with and without UPFC and TCSC FACTS devices using Newton-Raphson power flow algorithm and Genetic Algorithm (GA) for optimally locating these devices on the network. The heavily loaded active power lines were identified. The heavily loaded active power lines are thirteen (13). These include: Katampe

Wind energy is one of the cleanest sources of renewable energy sources (RES) in Nigeria but among the least utilized even with its enormous abundance. This work investigates wind energy availability and its utilization in some selected areas of the six geopolitical regions. The area under study is part of North-West (Gumel, in Jigawa State), Part of North-East (Maiduguri, Gamboru and Baga in Bornu State and Kumagunnam in Yobe State), Part North Central (Pankshin and Biu in Plateau State), Part of South-West (Lagos State), Part of South-East (Ihiala in Anambra State) and Part of South-South (Buguma in Rivers State). Rescreen (renewable energy) software was used to analyse the data obtained from Nigeria meteorological agency (NIMET). The result obtained showed the average wind speed for the various locations under study and it was found that there was drastic fluctuation of the speed of wind between June and October, and this was decreasing in this order. Furthermore, Kumagunnam and Gamboru has a high wind speed from January to march. This could be attributed to climatic/seasonal changes in weather pattern and it was also found that this is proportional to the cube of wind speed which is not linearly related to wind speed.

Electrification of Faculty of Engineering (FOE) located in Choba Campus in University of Port Harcourt is often realized through distribution network from Port Harcourt Electricity Distribution Company (PHEDC). FOE buildings, each consists of two floors with basement, academic staff offices, administrative rooms and public facilities. Huge sum of money is spent daily to run generators and noise pollution has come to live with us. Nigeria however has immense exposure to solar radiation all through the year. It has highest daily solar radiation of 7.0KWh/m 2 /day and lowest of 3.5KWh/m 2 /day. Choba has average radiation of 4.55kWh/m 2 /day and temperature of 27.23 0 C. Choba is at 4 0 49'27'' North latitude and 7 0 2'1'' East longitude and altitude (elevation) of 20m (64ft). Load profile for FOE was carried out to determine the number of solar panels and inverter rating. Monthly average radiation was obtained from Nigeria meteorological agency between January 2014 to December 2018.The proposed PV system plant capacity is estimated at 100kW based on estimated load profile. Various tools such as system yield factor, capacity utilization factor, performance ratio were used in carrying out performance of 100kW PV system. Plots of I-V characteristics at constant irradiance, P-V characteristics at constant temperature and irradiance and efficiency curve of P-V panels were obtained. The PV is expected to meet 123,228.38kWh annual load demand for FOE, using PVsyst software. This supply period of electricity is between official hours of 8am to 4pm daily and estimated that annual DC energy generated from the system is 126619kWh/year, whereas available energy exported is 121914kWh/year.
