Emissions reduction from a power system in India is traditionally considered in terms of installation of expensive abatement equipment. This paper describes a systems approach to achieve emission reduction targets for different pollutants in a least-cost manner that considers a wide range of options viz. adjustment within the system through integrated operations of the system and alternative mines-power station coal-supply linkages, coal imports, switching to cleaner modes of generation (from coal to gas), and installation of abatement equipment. A linear programming modeling framework is developed for the three electricity regions of India (western, southern, and northern) for different emission reduction levels for the four pollutants CO[sub 2], SO[sub 2], NO[sub x], and fly ash. The model considers the detailed coal mines-to-power plant linkages, the coal import for the coastal coal-based plants, details of all major interstate and inter-regional transmission lines, and the generating unit characteristics. It is found that installing abatement equipment in an attractive option for reducing fly ash and NO[sub x], that an additional gas-generation capacity is needed to reduce SO[sub 2] along with abatement, and that the share of gas generation increases drastically when a CO[sub 2] reduction constraint is incorporated.
