Year 2017 was the 3rd year since the first day of operation for this plastic factory. An average of 35% electricity usage was utilized during off-peak period and 7500 kW of maximum demand was declared. Connected load charge (CLC) of RM8.50/kW is applicable when the actual maximum demand recorded on any month is less than 85% of the MD declared in phases during year 1 until year 4 and less than 75% of the total MD declared for year 5 and year 6. Tabulate your results. a. Compute the monthly and total annual electricity cost for the post-retrofit period according to industrial tariff E3 (refer to Electricity Tariff Schedule TNB Malaysia in Open book materials folder). [CLO2-PLO4:03] (7 marks) b. Calculate the CLC costs per annum. Then determine a new MD declaration and calculate the savings on CLC in the same year based on your suggestion. [CLO2- PL04:04] (3 marks) (This tariff is effective from 15 January 2014 and supersedes the previous tariff schedule which was effective from 1st June 2011) Schedule 1 TNB tariff rates are set out as follows:- 8.
