Competitive PriceCompetitive PriceGas to coal competitionGas to coal competitionCoal based power plants give bus bar tariff of less than Coal based power plants give bus bar tariff of less than Rs 2/kWh. Gas based power plants must therefore Rs 2/kWh. Gas based power plants must therefore provide competitive tariff provide competitive tariff

• Economics (Pipeline Vs LNG)
Recent domestic gas finds
Energy security issues
• Kyoto protocol
–Will it impact financial viability of using indigenous coal?
• Inter-relationship of gas and power sector
–Impact of power sector reforms on Oil & Gas Sector
