According to the U.S. Department of Energy, a typical home in the United States uses approximately 900 kWh of electricity per mo
guapka [62]

Based on the energy generated by the power plant annually, the number of households the plant can support:

  • if energy usage is 10,800 kWh/year = 365000 households
  • if energy usage is 24000 kWh/year = 164250 households

<h3>What is electrical energy?</h3>

Energy is energy that is due to movement of electrically charged particles.

Electrical energy is used in homes for many purposes.

Electrical energy is sold in units of kWh.

Data provided:

Capacity of power plant = 500 MW

Capacity factor = 0.9

Average annual household energy usage = 10,800 kWh/year

Energy generated in a year = 24 × 365 × 0.9 × 500 MW = 3,942,000 MWh/year

3,942,000 kWh/year = 3,942,000,000 kWh/year.

Number of households the power plant can support = 3,942,000,000 kWh/10800 = 365000 households

Number of households the power plant can support is 365000 households

If monthly electricity usage increases to 1,200 kWh

In a year, energy usage = 1200 × 12 = 24,000 kWh/ year

Number of households the plant can support = 3,942,000,000 kWh/24,000 = 164250 households

Therefore, based on the energy generated by the power plant annually, the number of households the plant can support:

  • if energy usage is 10,800 kWh/year = 365000 households
  • if energy usage is 24000 kWh/year = 164250 households
