Stand alone small level power systems as a route to low investment decentralized systems with low gestation period is a worthwhile proposition which is being considered and implemented in many third world countries. When the concept of mini-grid is associated with renewable sources of energy such as solar, wind, hydro and biomass, small-decentralized power generation systems lessen the often over-dependence on fossil fuels. Fossil fuel are used at excessively and lead to warming problem due to net carbon-dioxide transfer into the atmosphere besides being a cause of unhealthy trade balance for developing countries. This paper describes a stand alone 0.5 MVA steam powered generator system, which utilizes agricultural residues as fuel. A complete technical description of the system is given. The economic and social impact of such a set-up is also given.
