13 EGAT Coal Procurement Strategy EGAT is procurement the high quality coal from the foreign to thoroughly support power plant life with adequate quantities. Contracting mix to take advantage of coal market positions Investment in overseas coal mines for coal supply security Quality requirements : Bituminous and Sub bituminous coal Competitive delivered cost To mitigate the risks: - Diversification of countries - Diversification of coal mines - Diversification of load ports 13

16 Conclusion Coal will remain one important fuel in Thailand s fuel mix to enhance energy supply security of the economy Environment impact and social perception on coal will play a dramatic role in power projects. The application of CCT by both power generation and industrial operators will reduce pollution emission from coal utilization CCTs Supercritical PC Cogen. CFBC Industry CWM 16
