Please answer the following questions in "Energy Efficiency Basics" multiple choice:

Which knowledge in the hands of an industrial consumer is most likely to lead to discovery of the most valuable energy cost savings?

The total energy bill

The energy bill split between sub-divisions of the plant

The energy bill split between end-uses on the plant

Time-based energy consumption profiles per end-use

السؤال 12

A facility has a demand ratchet rate structure of 75%. In the current billing month, the actual metered demand of the facility was 650 kW. During the previous 11 months, the highest peak demand was 940 kW. How much greater than the actual demand will the billed demand be?

15 kW

55 kW

453 kW

650 kW

Answer 1

11. The timely management of power utilisation in the industry will lead to most efficient energy cost saving ....This is due to the fact however even if the bill is spiltted either sub-divisional wise or between the end users the total energy used would be the same and charged at same tarrif as the previous....This would obviously be the same energy cost as the previous total energy cost. Hence Time based energy consumption profile as per end-use would be best energy cost saving method.

12.

• Highest peak demand in last 11 months =940kW
• Peak demand of this month =650KW
• A provision for demand rate structure of 75% is given .
• This means that the 75% of the max. Peak of last 11 months would be considered as the peak if peak of this month is less than that.
• So 75% of 940 KW would be charged if peak of this month is leass than 75% of 940kW
• 75% of 940kW= 705kW
• As the peak of this month is 650 KW which is less than 705kW .., So 705KW would be considered as max demand of this month.

So difference= 705kW-650KW=55KW
