60. SWOT analysis – fossil power Strengths Decentralised; Established technology, Significant research input to meet various end use, Centrally processed fuel available; Sales, service and other support network well established; Energy cost (was) a small fraction of the product cost; Ideal fuel for transport Weakness Fuel price linked to international market (now); Driven by governmental subsidy pattern; Global warning (now) ; Competition in product line – establish to reduce the fuel cost (now) Opportunities Small scale industries growing rapidly; Gestation period nearly zero; Energy costs (was) lower than grid cost Threats Environmental ; Governmental dependence on the pricing
61. SWOT analysis – Biomass power Strengths Decentralised; Strengthens self-reliance; Environmentally sound; Locally available fuel; Potentially adequate to replace fossil fuelled energy conversion Weakness Replicability not yet proven (Low visibility) ; Capital cost may (claimed) be too high; Fuel dispersed; Standardization of technology package with services, etc Opportunities Costs are declining; Gestation period low; Power generation costs lower than fossil fuel system; Fossil fuel substitution very high; Potential very high ; Available for continuous duty operation Threats Power sector reforms may under emphasize biomass based systems
