How Does Electricity Get Into Your Home?

1. Power Plant

Electricity begins at a power plant. Power plants can use coal, natural gas, nuclear energy, or renewable sources like solar, wind, or hydropower. These plants generate electricity at very high voltages to allow efficient transmission over long distances.

2. Transmission Lines

Electricity travels through high-voltage transmission lines supported by tall towers. These lines carry electricity across cities and regions. The high voltage reduces energy loss during transport.

3. Substation

At substations, the voltage of electricity is reduced using transformers. This makes it safer for distribution to local areas and prepares it for use in neighborhoods.

4. Distribution Lines

Electricity moves through distribution lines, usually mounted on poles. These carry lower voltage electricity into residential and commercial areas.

5. Transformer

A neighborhood transformer further reduces the voltage to a level safe for home use (typically around 220 volts in the Philippines). This ensures appliances can operate safely.

6. Service Drop

The service drop consists of wires that connect the distribution line to your home. These wires deliver electricity directly to your house.

7. Electric Meter

The electric meter measures how much electricity your household consumes. This reading is used by utility companies to calculate your bill.
