Reduction of APC by improving utilization factor ofCHP, Stage I units Feed Regulating Stations.

Differential Pressure optimization and ID fan margin

improvement.


20/31

Lower PLFReasons

High partial loading due to equipment problem

Coal shortage

Lower merit order


21/31

Lower PLF

Action for mitigation of risk Preventive and predictive maintenance planning

More coal being lifted with proactive persuasion with

CIL Optimization of ECR by discouraging high specific

cost coal, use of MGR/RJ coal with restricted blending,raniganj coal of G6 grade to be preferred instead of

G5/G4/G3 coal as there is steep rise in price.


22/31

Under recovery of O&M Charges

Reasons

Checks during O/H:

Action for mitigation of risk(Ash Utilization initiatives)


28/31

Action for mitigation of risk(Ash Utilization initiatives)

Initiatives for Fly ash Brick Sector: Presently 25 parties lifting 18000 MT/month of f ly ash from ash silo in free of cost

for use in Fly ash brick manufacturing against only one party in last year. Fly ash is being issued within 14 days in every case after submission of application

with proper documents. 25 more parties/persons applied for fly ash in this regard are in pipeline in

different stage Application format and procedure is made available in BSPCB site for more

accessibility. Initiatives for Clay ash Brick Sector A Demonstration project for ash utilization in clay-ash brick manufacturing has

been organized to raise confidence among brick manufacturers for use of ash inbrick manufacturing and to popularise the clay ash brick in place of clay brick. Workshops for Brick kiln owners/ ash brick manufacturers for using ash in

brick manufacturing. 15000 MT pond Ash is being transported on free of cost to Brick klin.

Other Initiatives for Maximizing Ash Utilization Dedicated Road for ash transportation is constructed from NTPC gate to

Ekchari, bypassing Kahalgaon town from May-2013. Wind breaking wall has been constructed and water sprinkling is being done

on regular basis at Kahalgaon railway siding. Ash transportation in Jumbo bags directly by railway successfully done on

12.09.2013 on trial basis and now it is streamlined. It is being done by oneparty, Railway is being contacted for other parties. This process iseconomical and environment friendly

Ash Utilization through low land filling for public utility land, compilation is

in advance stage. First phase quantity will be 2.5LMT.
