Mahagenco fly ash utilization unsatisfactory @ 63%

NAGPUR: Mahagenco has been frequently hauled up by environmentalists for not taking measures to control air pollution. The company has always defended its conduct by saying that poor quality coal makes it difficult to do that. Now, a Central Electricity Authority (CEA) audit has revealed that even fly ash utilization by Mahagenco is far below the minimum expected level.

Ideally, the entire fly ash should be used, but CEA considers performance by companies in the range of 75% to 100% utilization as satisfactory. However, Mahagenco’s utilization figure is 63%. The national average is 55.6%. The biggest power producer NTPC has a very poor record of 43% utilization.

While many generation companies fare even worse, there are some utilities, mostly private, that use the entire fly ash. CEA has compiled data for 66 companies for the first half of 2013-14. Sixteen power utilities have used the entire fly ash generated by them. Twenty-one have used up 75% to 100% while the remaining 29 are below 75% usage. Mahagenco falls in the third category.

During this period, Tamil Nadu has achieved fly ash utilization level of more than 98% while Delhi, Gujarat, Jharkhand, Punjab, Rajasthan and West Bengal achieved fly ash utilization level of more than 70%.
