Abstract: Nigeria's overdependence on non-renewable sources of energy has undermined economic growth for more than seven decades. Renewable energy generation promises an electric power supply of >60 gW. Although Nigeria has invested in hydropower as a source of electricity, there is a need to diversify into wind energy sources. This study examines the wind energy conversion systems potential at Ayetoro, Ondo state (latitude 6.1077997 °N and longitude 4.7721257 °E) using a year of data (June 2018 - May 2019) collected at 5 minutes interval. The data was collected from the Marine Science and Technology weather station, which used an Atmos 41 to record wind data at 5.5 m altitude. The wind speed data was adjusted to 50 and 90 m and fitted to the 2-factor Weibull distribution function. The wind directional frequency and operability of wind energy conversion systems were also calculated. About 62% of the wind blew from the South of the Atlantic Ocean. At 50 m altitude, the Weibull shape parameter (K) was 2.74, and the scale parameter (C) was 4.59 m/s. The wind power density peaked at 134.8 W/m2. This wind power density can be classified as class 1 on the NREL wind power classification. The operating probability of a wind turbine with a shut-in speed of 3.5 m/s at 50 m altitude was 62%. Therefore, we conclude that the wind energy potential of the Aiyetoro Coast of the Atlantic Ocean is currently operable for small-scale, local applications but not commercializable for state or national energy distribution.

Abstract: The research attempts to proffer a model solution to some of the problems, militating against the efficient management and maintenance of electricity distribution in Nigeria, using Durba – Kosobo Area as a case study. Thus, the project serves as a prototype for demonstrating the relevance of employing electricity distribution information system. The study site is the Dubar – Kosobo Area bounded by Owode Road to the North, the Apostolic Church Street to the East, Mobolaje Road by the West and by the Hon Raheem Wasiu Street to the South, all in Oyo East Local Government of Oyo State in Nigeria. It lies within Latitude 07° 49' 03" N, and 07° 50' 02" N, Longitude 03° 57' 03" E and 03° 56' 02" E. The relevance of the study is in fault detection, increased revenue generation, quick time to effect repairs, timely schedule maintenance of network facilities and a lot of other advantages. The electricity distribution information system is needed for planning and management. The database design consisted of design phase and construction/implementation phase was made using ArcGIS 10.2 suit of software. The followings were considered under the design phase namely, view of realty, conceptual design and logical design. Attribute data was collected through oral interview from both DISCOs and GENCOs official and the residents in the area about the street name, building use, transformer, and other relevant information. Head-up or on-screen digitizing was adopted on the acquired imagery to trace out the outline of the features within the study area. In the process different layers such as buildings and road-network were electronically traced out using the ArcGIS 10.2 software. This study recommended an increased sensitization and awareness campaign for all stakeholders who are potential users of GIS. The electricity distribution information system is needed for planning and management. It is recommended that the electricity provider, DISCOs and GENCOs Plc should adopt GIS as a tool for efficient management of her facilities to enhance their supply of electricity to users.
