Answer & Explanation

Correct AnswerD. (kWh supplied in a year) / (24 × 365)

Quick Explanation

Annual average load equals total electrical energy supplied during the year divided by the total hours in that year. Therefore Average Load = annual kWh/(365×24), which is option D.

Formula / Key Relation

Annual average load

= Energy supplied in year / Hours in year

= kWh_year / (365×24) kW

Detailed Explanation

Concept & Reasoning

Load is power, whereas kWh is energy. Dividing yearly energy by 8760 hours converts the area under the annual load curve into an equivalent constant average power. The same principle applies to daily or monthly average load using the corresponding number of hours.

How to Solve It in the Exam

Energy ÷ time = average power.

Important Exam Point

Match energy period with the same time period in the denominator.
