Electricity is produced at a generation facility either by renewable or non-renewable energy sources.
Transmission Lines and Substations
After the electricity is generated, it travels through high-voltage transmission power lines to electric substations, where the voltage is lowered. 1104490758730
Once the voltage is lowered the electricity travels over distribution power lines, which ultimately deliver the electricity to our homes and businesses.
Distributed generation systems like rooftop solar panels produce electricity when their energy source is available, such as when the sun shines. When the energy source is unavailable, the home or business receives electricity from the grid. If the system produces more electricity than needed, the excess power is sent back to the grid.
