The task ahead India’s growing economy requires adequate supply of energy Per capita consumption of electricity of 800 Kwh is lower than
world average of 2200 Kwh Energy deficit ~ (-7%) & Peak Demand Deficit ~(-9.4%) T&D Losses ~ 25 to 50% India’s installed electric power generation would have to
increase to 861 GW by 2030 to sustain economic growth of 8-9%.
India needs to effectively tap all sources of Power Generation

•CO2 emissions•Ash disposal•Coal transportation bottleneck through rail
Need for Clean Coal Technologies
•Supercritical/Ultrasupercritical
•Integrated Gasification Combined Cycle
• Carbon Capture & Sequesterization
Indian Coal Quality Issues with Coal based PowerInstalled capacity : 17624 MW
660/800 MW units planned for all future coal based projects Parameters adopted
247 kg/cm2 535/565 and 565/593 deg C Supercritical technology mandatory for Ultra Mega Projects Many more supercritical units in pipeline.

High efficiency ~ 43-45 %
Potential for achieving even higher efficiency ~ Using advanced class Gas Turbines( Up to 50 %)
Potential for Green House Gas(GHG) Reduction
Low water consumption: Since 2/3 of power is generated from Gas Turbine
India pursuing demo project of 100 MW- Feasibility study done by Nexant USA through USAID
Gas based power
•Gas Availability for power generation to be enhanced.
•Expanding gas pipelines/LNG terminals
•Advanced class Gas turbines : Thermal efficiency of 60%
