QUESTION #20 MARKS The contracted demand of a chemical plant is 1000 KVA The average monthly MD recorded is 800 KVA only. The average monthly energy consumption is 1.6 million unit. The utility bill analysis provides the following billing components. Minimum monthly billing demand is 80% of contracted MD or the actual recorded MD whichever is higher. Minimum power factor may be maintained is 0.9 0.5% of unit charge for every 0.01 point below the 0.90 PF will be charged additionally as penalty. 0.5% of unit charge for every 0.01 point above the 0.95 PF will be given as incentive for maintaining higher power factor. MD charge is RM300 per KVA Energy charges is RM0.4 per KWH Energy Manager of the plant has proposed to improve the power factor from 0.86 to 0.96 by adding capacitors in the distribution system. Determine the following: a) MD reduction in KVA (10 Marks) b) Monthly Cost saving.
