Abstract: | This study analyses ex-ante socio-economic impacts of biogas systems using a remote rural community
in Ghana as a case study. An analysis was performed for a 300 m3 bio-digester that relies on crop residue
and animal manure as feedstock to produce methane gas for cooking using selected bioenergy economic
and social indicators. With a 10% discount rate, a 30 year bio-digester lifetime and methane tariff starting
at US$ 0.7/m3, the project will have a Net Present Value of approximately US$ 22,000, 16 year payback
and an Internal Rate of Return of 11%. The project will create 4 full time unskilled labour positions during
the investment year and 3 positions during operation years. Using methane from the bio-digester for
cooking will displace approximately 170 tonnes of firewood per year and save the women in the community
a total of 3400 hours per year not fetching firewood. However, only 5% of households are willing to
pay the base tariff of US$ 30/m3 with up to 60% willing to pay less than half the monthly tariff. To make
tariffs affordable to rural households, there is the need for subsidy schemes from government or relevant
agencies. |
