Techno-Economic Assessment of Liquefied Petroleum Gas-Based Alternative Electric Power Generation in Selected Residential Estates in Oyo State, Nigeria

This study examined the technological and economic parameters for Liquefied Petroleum Gas (LPG)-to-Power generation in housing estates in Oyo State, Nigeria. Technological and economic data were obtained through literature, questionnaire and site inspection. An energy project foresight analysis framework was used. The results showed that the housing estates had daily grid electricity demand range from 1438.43 – 8209.98 kWh. The technological specifications revealed gas turbine generator specifications from 0.6 – 3.5 MW and LPG storage tank specifications for 30 days from 30 – 171 m3. Environmental specifications showed CO2 emission mitigation from 331 – 1888 kg. The alternate diesel generation option has storage tank specifications for 30 days from 19 – 109 m3 while CO2 emissions were from 1553 – 8867 Kg. Life Cycle Costs (LCC) for the LPG plant were N 122.74– 132.35/kWh and N 151.62–160.81/kWh for the diesel generator option. The LPG-to-diesel generator estimated annual fuel costs savings were N 229.05 million. The study concluded that LPG option was technologically and economically viable and was a more appropriate alternative electricity option relative to the existing diesel alternative electricity generation option.
