Where does Los Angeles get its electricity from?

Have you ever wondered where the electricity in your house comes from? It’s a bigger question than you might think! Every single one of LA’s power-consuming structures is connected to our gigantic, multi-state, billion-dollar energy system. Your humble home is the end of a story stretching hundreds of kilometers and involving thousands of people.

The power supply that Los Angeles uses every day is a technical marvel. We’re giving you the shocking truth about where the energy that powers your coffee maker every morning comes from. Enjoy Mike Diamond’s Guide to Los Angeles Power Networks.

Who is the power of Los Angeles?

The Los Angeles Department of Water and Power (LADWP) provides all of the electricity that LA uses on a daily basis. The LADWP is that largest public utility company in the country. 9400 employees help manage an electrical system that has over 7,880 megawatts of power. In total, the LADWP power system delivers over 26 million on average Megawatt hours of electricity to LA every year.

The LADWP was founded in 1902 to deliver water to LA. In 1916 it also started distributing electricity. The LADWP is led by five members Board of Water and Power Commissioners selected by the mayor of LA and approved by the city council.

What creates all the power of LA?

According to the California Energy Commission 2019 report, California generates its electricity in the following ways:

  • 0.12% coal
  • 16.53% large hydropower
  • 42.97% natural gas
  • 8.06% nuclear
  • 0.02% oil
  • 0.20% crude oil / waste heat
  • 2.92% biomass
  • 5.46% geothermal
  • 2.67% small hydropower
  • 14.22% sun
  • 6.82% wind

California is a national leader in renewable energy generation. Every part of California – including LA – is rapidly scaling its use of renewable energy. By 2030, the state wants to obtain 50 percent of its electricity from renewable sources.

In order to achieve this goal, the LADWP is involved in the Strategic long-term resource plan for Power (SLTRP). The SLTRP is a 20-year plan to align LA with Senate Bill 350 and LA’s 100% clean energy initiative. As part of this plan, LA will eliminate coal as an energy source, reduce natural gas consumption, incorporate more renewable energy sources, and more.

LA power generation and transmission

Where the Los Angeles Electric Company gets its electricity

The LADWP sources the power it delivers to LA from many sources, both inside and outside California. You’d be surprised to find your power comes from Arizona, Utah, Wyoming, and Oregon. These sources include:

  • Hydropower plants
  • Natural gas power plants
  • Landfill biogas conversion stations
  • Hydropower plants
  • Solar systems
  • Wind turbines
  • Geothermal plants
  • Nuclear power plants

All of these power sources are massive transmission and distribution Infrastructure. In order to move and distribute the power of LA the following is required:

  • 3,507 miles of overhead power lines (in five states)
  • 124 miles of underground transmission lines
  • 15,452 Transmission masts
  • 6,752 miles of overhead lines
  • 3,626 miles of underground distribution lines
  • 160 Distribution stations
  • 21 receiving stations
  • 128,693 distribution transformers
  • and more

A total of 25,000 miles of power lines and cables are required to carry and distribute LA’s power!

How power gets to your Los Angeles home

This infographic explains the high voltage journey electric power takes to your home. The steps are described in more detail below the graphic.

How does LA's power come to you?

‌Phase 1: transfer

1. System for the “Step Up” substation

A Los Angeles substation.

Each of LA’s many power generators is connected to a substation (sometimes called a power station).

Substations “increase” the voltage in order to prepare the electricity for long distances through the transmission network. Whenever an electrical current is passed through something (like transmission lines) it loses some energy electrical resistance. The higher the voltage of the current in the transmission line, the more less current resistance wasted. By “overloading” the voltage of the electricity generated, substations ensure that it reaches you without losing its effectiveness.

2. First substation to the transmission network

After converting low-voltage electricity to very high-voltage electricity, substations send electricity into transmission circuits. These circuits run from the substation near the facility to the local substations in your city. A single transmission line can hold up to. successfully conduct electricity 300 miles.

There are two types of transfer circuits:

Overhead lines Transmit electricity over long distances. You are supported by the huge steel transmission towers that you are probably familiar with.

Underground circuits are used in high-density urban areas where there is no space for transmission towers. LA uses 124 miles of underground electrical circuits.

Phase 2: Distribution

3. Transmission network to the “Step Down” distribution station

The Los Angeles transmission grid carries electricity to you,

Your energy has already traveled hundreds of miles down the transmission lines to reach your area. However, before it can get into the distribution network, it has to pass another substation. Instead of charging the electricity with more voltage, these transformers remove the voltage to make it safe for distribution.

After passing through the transformer, the electrical power reaches a “distribution bus”. The distribution bus divides the current in several different directions. LA uses 160 substations to transfer its electricity to distribution.

4. Second substation to the distribution network

Now your power is almost yours. After passing through the “step-down” transformer and the bus in the substation, the electricity enters the local distribution network.

LA’s distribution network, as you can probably imagine, is huge. The city uses 6,752 miles of overhead power lines and 3,626 miles of subway distribution lines. These lines run through the entire city in order to supply every single connected building with electricity.

5. Distribution network for you!

A transformer from Los Angeles.

As soon as the distribution line reaches your immediate area, it connects to a Distribution transformer -Either carried on pylons or buried underground.

Distribution transformers “reduce” the amount of electricity that flows through the power lines. This process lowers the voltage of the electricity to around 240 volts to make it safe for home use.

This reduced current flows through the house connection line from the distribution transformer to the meter box in your house. The meter box records how much electricity is entering your house and what voltage this electricity is. The electricity flows through the meter box and into your circuit breaker, where it is distributed throughout your home via your electrical panel.
