| After deciding to set up ultra mega power projects (UMPPs) to improve power supply across the country, the government’s next big step would be to set up eight ultra supercritical power plants (USCPPs). It is well accepted that power generation is the primary contributor to greenhouse gas (GHG) emissions in India. This however, does not mean that in meeting our electricity needs we have to be environmentally insensitive. A viable and sustainable solution lies in encouraging generation from “clean” coal. It is important that India moves away from subcritical pulverized coal or “dirty” coal to commercial supercritical combustion technology. The supercritical coal based units have faster starting time & load changes and are more suitable for daily start up/shut down operation and have better efficiency at part load operation. While the adoption of supercritical technology in the coal power plants is a part of the proclaimed government agenda, the poor achievements of the same in the tenth five year plan mean a lot has to be done in order to make them a reality. |
