Thus, total demand = (8,400 × 10) + (3,600 × (10 – 8)) = 84,000 + 3,600 × 2 = 84,000 + 7,200 = 91,200 kWh.

Total Energy Demand Calculation: A Step-by-Step Breakdown of 91,200 kWh

Understanding total energy demand is essential for effective planning in utility management, grid operations, and sustainability initiatives. One effective way to compute total energy consumption is by using a structured formula that breaks demand into clear components—this is exactly what happens in a detailed calculation like Total Demand = (8,400 × 10) + (3,600 × (10 – 8)) = 84,000 + 7,200 = 91,200 kWh.

How the Equation Works – A Clear Explanation

Understanding the Context

This expression captures how different phases of energy use combine to form a complete demand figure:

First term (8,400 × 10):
This represents consistent demand over a period—here assumed at 8,400 kW for 10 hours. Multiplying 8,400 by 10 yields:
8,400 × 10 = 84,000 kWh
Second term (3,600 × (10 – 8)):
This accounts for an adjusted demand during a shorter interval—specifically, 3,600 kW over 2 hours. Subtracting 8 from 10 gives 2, so:
3,600 × 2 = 7,200 kWh

Combining both, the total demand becomes 84,000 + 7,200 = <<84000+7200=91200>>91,200 kWh.

Thus, total demand = (8,400 × 10) + (3,600 × (10 – 8)) = 84,000 + 3,600 × 2 = 84,000 + 7,200 = <<84000+7200=91200>>91,200 kWh.
