Obtained permission for disposal of 10.00 Lakh MT Ash in low Lying Area from Land Owner & RO –CECB. Major Concerns: Facing difficulties in smooth functioning of plant due to lack of Man Power Manpower : Critical Vacant position / Required Numbers in all departments are as below: Operation : Executive = 08/24 ( UCE= 2/4, Boiler Desk Engr = 2/4, TG Desk Engineer= 3/4 ,), Non Exe- 12/24 (Boiler/TG/Comp/FOPH Operators) Mechanical Maintenance = 05/ 11, C&I = 04/ 12 AHP=01/04, CHP=01/03,, WTP = 01/ 07, Electrical = 02/ 15, Environment Head- 01/01 Others (Coal – CIL, Ash disposal, Admin, OHC, Stores, etc.) = 8/23 Annual Increment of staff. C- off policy . Incentive policy with Deemed PLF. Steam Leakage from LP Turbine front gland seals. Ash Generation & Disposal report in Nov 2023 : Ash Generated =51440 MT ( Ash %- 44.30 %) Ash disposed for Construction of Road ( NHAI ) + Low Lying Areas =95957 MT 38
