Abstract :
This study analyzed the electricity generation potential from wind at Kano, Nigeria (12.05°N; 08.2°E; altitude 472.5 m;
air density 1.1705 kg/m3). Twenty one years (1987 to 2007) monthly mean wind speed data at a height of 10 m
were assessed from the Nigeria Meteorological Department, Oshodi. The data were subjected to different statistical
tests and also compared with the two-parameter Weibull probability density function. The outcome shows that the
average monthly wind speed ranged from 6.6 to 9.5 m/s. Seasonally, average wind speeds ranged between 6.6 to
8.5 m/s and 7.4 to 9.5 m/s for dry (October to March) and wet (April to September) seasons, respectively. Also,
estimated monthly wind power ranged between 3.6 and 12.5 MWh/m2. The most probable and maximum energy
carrying wind speeds were also determined and the two parameters of the Weibull statistics were found to lie
between 2.1 ? k ? 4.9 and 7.3 ? c ? 10.7, respectively. These results indicate that wind speeds at Kano may be
economically viable for wind-to-electricity at and above the height of 10 m. In addition, five practical turbine
models were assessed for the site’s wind profile, with results suggesting strong economic viability.
